WATER RESOURCES
SERVICE
V. Raudsepp, P.Eng.
Deputy Minister of
Water Resources
It would be fair to describe 1972 as a significant year in the history
of the British Columbia Water Resources Service.
This year saw not only the 10th anniversary of the establishment of
the Water Resources Service as a separate Service within the Department
of Lands, Forests, and Water Resources, but faced the Service with heavy
challenges, expansion, and reorganization. At all staff levels the challenges
were accepted enthusiastically and with a sense of pride that, in so short
a life-span, the Service had grown to be one of the most basically essential
of the resource-use and environment-protection Services within the structure of the Government of British Columbia, as permitted within the framework of the policies of the Province.
That 1972 was to be a year of challenge became apparent during the
year's early weeks, with our Snow Survey Bulletins reporting abnormally
heavy snow-packs lying throughout the Province, posing the threat of
potentially disastrous flooding during the freshet period. The threat materialized, serious flooding did occur on a wide scale, but precautionary
measures were taken in time and a major disaster averted in areas where
water storage had been developed. A full report of this flood threat and
resulting damage is attached to these introductory notes.
The flood damage caused by the 1972 snow-melt and heavy rainstorms
demonstrated that extensive land developments for residential and commercial use had taken place on flood plains and other areas which are
subject to water damage. The Government instructed the Water Resources
Service in July to review all future land subdivision and rezoning proposals
from a flood-control point of view. This assignment to the Deputy Minister
involves a review of all the land-zoning by-laws sent to the Department of
Municipal Affairs and all the subdivision proposals on flood plains submitted to the Department of Highways. A total of 105 proposals was
reviewed in 1972.
One more fortunate result of the heavy snow-pack was that, in terms
of availability of water supply, 1972 was an excellent year with stream-
 Y 10

flows across the Province well above average and consequently very little
demand for water-use regulation based on minimum supply conditions.
There are now four main arms of the British Columbia Water
Resources Service—(1) Water Rights Branch, from which the Service
originated and which controls the use of surface water under authority of
the Water Act and supervises the administration of improvement districts
incorporated under that Act; (2) Water Investigations Branch, which deals
with technical water resource matters not falling directly under the terms
of the Water Act; (3) Pollution Control Branch, which administers the
Pollution Control Act, 1967, as amended; (4) the Service's large Chemistry
Laboratory, located in Vancouver and absorbed from the Department of
Health Services in 1971.
Additionally, there are (5) the Pollution Control Board, which deals
with pollution control standards and appeals from decisions of the Director of the Pollution Control Branch; (6) the Inspector of Dykes, who
administers the Dykes Maintenance Act; (7) the Supervisor of the Southern Okanagan Lands Project; (8) the Personnel Officer; (9) the Departmental Comptroller, handling the Service's accounting system; and (10)
the Mail and File Room.
All of these branches and ancillary services reported major increases
in their responsibilities and work loads during 1972.
Water Rights Branch issued a record total of 1,746 water-use licences
during 1972, bringing the number of licences in effect by year's end to
26,873. Work continued on the vital task of updating more of the Province's very old water rights maps, and increased administrative efficiency
was reported through the use of the Branch's new data processing system.
The administration, engineering, legal, and accounting services for
British Columbia's 305 improvement districts—which operate local community water supply, irrigation, drainage, sewerage, and other works—
involved a high level of participation by the Branch, whose District Engineers also were subjected to increased demands on their time and resources,
particularly due to their growing involvement with the Province's regional
districts.
Water Rights Branch's Power and Major Licences Division had an
exceptionally active year in 1972. Division staff took the initiative in
securing the drawing-down of major reservoirs and other peak-flow reduction efforts to avert a major flood disaster, and were actively involved in
various aspects of implementation of the Columbia River Treaty, notably
in connection with the Kootenay Canal Plant project, Mica Dam Reservoir
preparation, and the initial filling programme for the Libby Reservoir (Lake
Koocanusa ).
Estimated electric energy generated in the Province during 1972 saw
a 10.4-per-cent increase over 1971 to a total of 31,446 million kilowatt-
hours.   Of this, some 834 million kilowatt-hours were net export.
 DEPUTY MINISTER'S REPORT
Y 11
Water Investigations Branch continued its long-term studies of the
Province's undeveloped hydro-power potential, notably in connection with
the Liard River and, in conjunction with the British Columbia Hydro and
Power Authority, the Lower McGregor and Clearwater River systems in
connection with the Federal-Provincial Fraser River flood-control storage
review.
Growing participation in joint Federal-Provincial agreements placed
heavy strains on the senior Water Investigations Branch staff. Among
these agreements are the Fraser River Flood-control Programme, the four-
year Okanagan Basin Study, and implementation of the ARDA (Agricultural and Rural Development Act) water projects programme.
On a more intensive scale than the Okanagan Basin Study, the Branch
during 1972 entered its second year of the Service's own water-quality management study of the Kalamalka-Wood Lake watershed. In November
1972 a well-attended public information meeting was organized by the
Branch to give the local community opportunities for discussion of the
first year's progress report on this study. Later, the same month, a similar
public meeting arranged for land-owners in the Southern Okanagan Lands
Project area was also much appreciated locally.
Pollution Control Branch in 1972 underwent its sharpest-ever increase
in staff—from 1971's establishment of 85 to a new 1972 total of 185—,
moved into greatly expanded headquarters office space in Victoria, and considerably increased its district office staffs and facilities throughout the
Province.
During 1972 the Branch conducted three further public inquiries into
pollution control technology for British Columbia's major industries—in
March at Cranbrook and Vancouver into the mining and allied industries;
in May at Vancouver into the petro-chemical industry; in November at Kamloops into the food-processing, agriculturally oriented, and other miscellaneous industries. Preparations were also well advanced for a further
inquiry into municipal-type waste discharges, scheduled for April 1973 at
Victoria.
From all these inquiries it is planned that reports embodying specific
sets of minimum waste-treatment objectives ("pollution control codes")
are submitted to the Pollution Control Board by the Director of the Pollution Control Branch for adoption as official pollution control policy guidelines throughout the Province.
On November 1, 1972, the Minister of Lands, Forests, and Water
Resources announced, in interviews carried by all news media, that the
Provincial Government had decided to start enforcing the Pollution Control
Act's penalty provisions through the Courts. Pollution Control Branch, in
close association with a Departmental Solicitor seconded from the Attorney-
General's Department for service in the Water Resources Service, has been
actively pursuing this change in Cabinet-level policy, and by the year's end
a number of prosecutions were before the Courts.
 Y 12
B.C. WATER RESOURCES SERVICE
The Chemistry Laboratory also saw a major increase in staff during
1971 (from 32 to 52) and a 67-per-cent increase in the yearly total of
analyses performed, to 92,000 compared with the 1971 total of 55,000.
In October 1972 the Laboratory completed and released its final report
on an air-quality study in the Lower Mainland area of the Province, this
three-year study having originated in 1968 by the Public Health Service
prior to the Laboratory's transfer to the British Columbia Water Resources
Service.
The above-mentioned study is a part of several research projects and
studies under way by the Water Resources Service's own staff. Additionally,
the Service financially sponsors some research projects, graduate studies,
and other activities by external agencies and specialists, notably at the
University of British Columbia and the British Columbia Research Council. During 1972, these external research activities have included a solid-
waste recychng study; a study of hydrologic modelling and into the
problems of operating a flood-control reservoir to best advantage; experiments with a computer technique as an aid in planning river engineering
works; pollution control-oriented studies of leaching from sanitary landfills; and the decomposition of wood residuals.
These introductory notes are now followed by special reports on implementation of the Fraser River Flood-control Programme, a report on the
1972 flood damage in British Columbia and, in subsequent pages, the
detailed annual review of operations for 1972 by the separate branches and
sections of the British Columbia Water Resources Service.
The British Columbia Water Resources Service has received valuable
assistance in its work from many departments of British Columbia and
Government of Canada administrations and numerous outside institutions
such as universities, local governments, and individuals and associations
who have brought forward ideas and suggestions which have provided additional enlightenment in the difficult task of water resource and environmental quality management.
FRASER RIVER FLOOD-CONTROL PROGRAMME
The Fraser River Flood-control Programme under the Federal-Provincial agreement of 1968 was not particularly active on the ground during
1972, for, although there were numerous applications in hand for the
improvement of dyking, drainage, and bank protection, much of the work
carried out during the year was related to studies and designs, and in particular to reviews by the municipalities of the project proposals prepared
for execution. Only one project was initiated in the field. An agreement
between the Province and the Corporation of the District of Matsqui led to
the start of river-bank protection and dyke improvement in that municipality.   Details of this programme are to be found elsewhere in the Report.
During 1972 the West Langley Dyking District, the East Langley Dyking District, the Salmon River Dyking District, and the Derby Dyking Dis-
 DEPUTY MINISTER'S REPORT

trict, all improvement districts under the Water Act, were dissolved and
their assets and liabilities transferred to the Corporation of the Township
of Langley. Municipal forces assumed responsibility for the upkeep of the
flood-control and drainage works. Some or all of these areas will have
works improved or built under the Fraser River Flood-control Programme,
with the municipality participating in the role of the local authority.
FLOOD DAMAGE, 1972
A significantly high spring run-off on all Mainland streams from a
high snow-pack caused localized flooding in many areas of the Province.
Major rivers and their tributaries provided the greatest concern, and damage to private property and crop loss occurred in many valleys from the
Peace River to the southern boundary of the Province.
For comparative purposes, it can be noted that the maximum daily
discharge of the Fraser River at Hope was 457,000 c.f.s., which is the
second highest on record, only being surpassed by the recorded peak flow
at Hope in 1948 of 536,000 cf.s., and an estimated discharge of 620,000
cf.s. in 1894.
On June 16, 1972, the Premier of the Province announced that the
Government of the Province of British Columbia was prepared to help
individuals who had experienced property damage, and the municipalities
where public works had suffered, by providing financial assistance from
the Provincial Major Disaster Fund. The Province engaged the services
of the Canadian Independent Adjusters Conference and a Flood Reparations Committee was established to review and approve all claims appraised
by the Conference members.
Claims were received from many parts of the Province. One of the
hardest hit areas was the Similkameen Valley and its tributaries, where
recorded flows were exceeded and losses were significant. Three houses
on Hedley Creek in the settlement of Hedley were completely destroyed,
including total erosion of the properties. Major erosion also occurred on
Allison Creek and Summers Creek. Orchards and farm lands in the
Similkameen Valley were inundated, resulting in loss of land and crops.
The high discharge of the Similkameen River at the confluence with the
Okanogan River in the State of Washington created an anticipated reversal
of flow in Osoyoos Lake, with resultant flooding at Osoyoos and adjacent
shoreline. Over 550 claims were approved from the Similkameen-Osoyoos
area.
The City of Kamloops and its adjoining municipaUties were subjected
to high river-levels. Aggressive action was needed and emergency dyking
and evacuation procedures were in force for several days. From this area
alone, approximately 330 claims were processed.
Elsewhere in British Columbia, communities such as Prince George
and local points in the Okanagan Valley and in the Kootenays suffered in
varying degrees.     The  Lower Fraser Valley experienced  heavy  seepage
 Y 14 B.C. WATER RESOURCES SERVICE
from high river-levels which reached a maximum of just over 23.3 feet
on the gauge at Mission.
The southwest portion of the Province received an unprecedented
rainstorm on July 12 which caused damage to homes along Vancouver's
north shore and inundated farm crops in the lowlands between Chilliwhack
and the sea. Individuals affected by this storm were granted financial help,
and claims for damages were included in the assistance programme.
By the end of December, 2,775 claims had been processed and, including expenses, the Province had approved for payment from the Provincial Major Disaster Fund a total of over $7,668,500. Of this amount,
approximately 90 per cent has been paid out by the year's end.
At the completion of this flood-damage assistance programme, it is
estimated that approximately 2,950 claims will have been processed and
the total amount paid from the Provincial Major Disaster Fund will be in
the order of $8,034,000.
Late December rains created localized flooding conditions in the
Duncan area of Vancouver Island. The Province extended financial assistance for this area from the Provincial Major Disaster Fund, and, by the
year's end, approximately 100 claims for private-property damage were
being appraised by independent appraisers.
 WATER
RIGHTS
BRANCH
The Water Rights Branch is the agency of the Provincial Government which administers
the control and use of surface water under the authority of the Water Act.
The main principles of the Water Act regarding the use of water are:
(1) The property in and the right to the use and flow of all the water at any time in
any stream in the Province are for all purposes vested in the Crown in the right
of the Province. The common law principle of riparian water rights has been
abolished.
(2) Prospective users of water must file applications for water licences. There is a
procedure for notifying the Deputy Ministers of Agriculture and Recreation and
Conservation and all those whose rights might be affected, all of whom have a
right of objection to water applications.
(3) Licence-holders have a right to the use of water under the terms and conditions
of the water licence issued by the Comptroller of Water Rights. Earlier licences
have priority over licences issued later.
(4) Retention of a water licence is dependent upon the beneficial use of the water,
payment of the water-licence rentals, and observance of the regulations of the
Water Act.
(5) A water licence is generally made appurtenant to a parcel of land, mine, or
undertaking, and it will pass with any conveyance or other disposition thereof.
(6) If it is necessary that a water licensee construct works on another person's land,
he can expropriate the land reasonably required if a voluntary agreement cannot
be reached. If the works will be on Crown land, the water licensee may acquire
a permit to occupy Crown land for such purpose.
The second major function of the Water Rights Branch is to generally supervise and assist
in the administration of the improvement districts which have been incorporated under the
Water Act for irrigation, waterworks, drainage, dyking, street-lighting, fire protection, and
several other purposes. An improvement district is a self-governing public corporate body
administered by elected Trustees. The undertaking of an improvement district can be financed
by Provincially guaranteed debenture issues.
The administration of the Water Act is carried out by the Comptroller of Water Rights
and his staff, who are located at a headquarters office in Victoria and district offices at Victoria,
Kamloops, Kelowna, Nelson, Prince George, and New Westminster.
Water is a natural resource which often has a controlling influence on economic development of other resources and, therefore, is in competitive demand by the utilizers of other
resources. Much of the vast industrial expansion presently occurring in this Province is associated with the use of British Columbia water.

 WATER
RIGHTS
BRANCH
H. D. DeBeck, P.Eng.
Comptroller of Water Rights
The Water Rights Branch is responsible for the administration of all use of
surface water in British Columbia under the provisions of the Water Act. For this
purpose a licensing system has been developed in British Columbia over the course
of the last century which applies to all surface water in the Province with provision
for extension to groundwater licensing when required. In addition to providing
for the administration of water use, the Water Act also makes provision for the incorporation of improvement districts which provide local services in water-related
and other fields.
On-the-spot investigation and determination has been a guiding principle in
the administration of the Water Act for many years, both in new licensing and in the
administration of existing rights. For this purpose the Branch maintains six district
offices staffed mainly by engineers and technical people who are available for the
first-hand investigation of all sorts of water problems in addition to licensing matters.
By the use of district and headquarters staff, the Water Rights Branch carries out a
great number of engineering studies on water matters, including water supply,
erosion, flooding, and dam safety.
The year 1972 was marked by floods in many areas of the Province, resulting
from an exceptionally heavy snow-pack and heavy rains during the melting period.
On some streams it seems likely that the flood flows may have been the highest
during this century. All district engineers were heavily involved in activities related
to the floods, and the Power and Major Licences Division provided staff work for the
Comptroller in directing the operation of major storages in the Province for flood-
abatement purposes. Significant peak-flow reduction was achieved by this means
on the Fraser River, and almost full control was achieved on the Columbia River.
The co-operation of major storage licence-holders, such as British Columbia Hydro
and Power Authority and Alcan, as well as many other licensees, was very much
appreciated.
The flood situation resulted in excellent water supplies throughout the summer
in most streams, with a resulting reduction in the need for water-use regulation by
District Engineers. This was fortunate, because work related to floods had required
about two months of full staff commitment at most district offices.
In the field of water licensing, the number of new applications received was
down slightly to 1,515, while the number of conditional licences issued increased to
1,746. In records going back to 1959 this was the first year in which conditional
licences issued exceeded new applications, although it should be noted that this
situation results in part from the number of licence amendments from which new
conditional licences are issued to replace old licences.   However, there has been a
17
 Y 18 B.C. WATER RESOURCES SERVICE
reduction in the number of water licence applications outstanding to 2,522 from last
year's peak of 2,827. Although this reduction, the first since 1964, is gratifying, it
should be noted in this connection that the number of applications presently outstanding is equivalent to about one and one-half years' output of new licences.
The water rights maps maintained in our Administrative Draughting Room are
probably the most essential of the working records used in water resource administration. In addition to their use for recording water licences and applications, they
are also used in clearance procedures for applications under the Pollution Control
Act, 1967, the Land Act, and the Forest Act. Administrative procedures are made
more difficult because coverage of the Province by maps of this series is far from
complete and because many of the water rights maps in use are more than 40 years
old and in very bad condition. For this reason it is gratifying to be able to report
that the Draughting Office was able to produce 107 new maps during 1972, thus
maintaining the new high level of production established last year, which was more
than double the rate of new map production over the preceding five years.
In dealing with applications for new licences, the main burden rests on the
District Engineer, who is responsible for the inspection of every application. Objectors are contacted to ensure that they fully understand the application and that
they have an opportunity to state fully their objections. The engineer makes a firm
recommendation on each application, and for practical reasons these recommendations are usually accepted by the Comptroller. The work load resulting from new
applications has greatly increased in recent years, not only because of the increase
in the number of applications but also because of the increasing complexity of many
of these applications and the increasing number of objections. At the same time
there has been a steady increase in the variety and complexity of the other responsibilities of district office staffs resulting from such problems as flooding and erosion,
resource-use conflicts, and the greatly increasing scope of the activities of regional
districts in which the District Engineers participate as members of the technical
planning committees.
A new and enlarged data processing system was largely completed during the
year. The value of this new system has already been demonstrated by the usefulness
of many special print-outs made to assist in engineering and administrative studies.
Alphabetical and numerical card indexes have been provided to the district offices
as a result of the adoption of this system, thus providing for simplified and standardized record-keeping at these offices
The upward revision of water licence rentals, which was fully in effect for the
first time in 1972, resulted in adjustments to quantities for some licences and the
abandonment of others. The number of water licences in effect as of December
8, 1972, was 26,873, comprised of 12,494 final licences and 14,379 conditional
licences.
Activity in the Improvement Districts Division continued high during the year.
A number of feasibility studies was carried out with regard to proposed new systems,
or the rehabilitation of old ones, and final design and supervision of construction
were provided for several small projects where special circumstances warranted such
assistance. However, the main responsibility of the Division continued to be administrative, involving a continuing general review of district administration and
capital projects involving borrowing. Many proposals prepared by consultants were
reviewed with respect to both technical suitability and economic feasibility.
A new responsibility was undertaken during the year in connection with the
continuing surveillance of the operation and maintenance of irrigation systems constructed with Federal and Provincial Government funds under the ARDA pro-
 WATER RIGHTS BRANCH
Y 19
gramme. By agreement with the Federal Government, the Province assumes the
responsibility for the proper operation and maintenance of all such systems, in order
to assure compliance with the intent of the statutes involved an<i tne agreements
made under them. A programme in this regard is still in the early stage of development. In particular, the effect of the service of subdivisions from these systems is a
matter of major concern.
The Power and Major Licences Division continued, during the year, to be
occupied with various aspects of the Columbia River Treaty development, particularly with the Canal Plant project. The Water Resources Service has been assigned
a co-ordinating role in the preparation of the Canadian portion of the Libby Reservoir which is being carried on by several departments of the Government of British
Columbia, and liaison is also being carried on with United States authorities. Staff
work on these matters has been provided by the Power and Major Licences Division.
This has included maintaining staff in the field during the critical portions of the
initial filling programme.
Because of the wide seasonal variation in stream-flows in British Columbia, the
storage of water is one of the most significant features of water management in the
Province. More than 600 storage dams of all sizes are now under licence in British
Columbia. In some circumstances such dams are capable of imposing a severe
hazard to life and property, particularly in the mountain valleys of British Columbia.
For this reason a programme of inspection of storage dams is carried on, based on
the powers of the engineer and the Comptroller under the Water Act. This programme is divided between the staff of the district offices and the headquarters staff
of the Power and Major Licences Division. The importance of this programme was
demonstrated during the record floods last spring, when many storages were operated
for flood-abatement purposes and no dam failures occurred.
The activities of the Water Rights Branch for 1972 are recorded in greater detail in the reports of the individual divisions of the Branch in the pages following.
WATER LICENSING DIVISION
W. R. Tuthill, Chief of Division
The Comptroller of Water Rights administers the Water Act, under which rights
to the diversion of water within the Province are granted for almost every conceivable use. Licences are issued for domestic, waterworks, irrigation, mining, industrial, power, storage, and other purposes. Licences are required, with few exceptions, before any person, company, corporation, community, or government agency
uses water from any surface-water source.
The Licensing Division is responsible for the processing of new applications for
licences and amendments to existing licences. In order to maintain complete records,
the Division is divided into two offices—the General Office, which handles the clerical
aspects of licensing, and the Draughting Office, which handles the mapping requirements. These offices are responsible for maintaining the many files, indexes, maps,
and other records required for the orderly processing of new and pending applications
and keeping track of the rights granted under existing licences and amendments
thereto. Close liaison is required with the District Engineers Division and its six
district offices, situated at strategic locations in the Province, for field investigations
and reports on applications and amendments.
The upward revision of rentals in 1972 resulted in many adjustments to quantities and the abandonment of some licences.

 WATER RIGHTS BRANCH
Y 21
The enlarged data processing system was completed during the year, with the
exception of the inclusion of the major power licensees. Many special print-outs
were made utilizing the system to assist in administrative and engineering studies.
Alphabetical and numerical card indexes were provided for all the district offices.
Compilation of new water rights maps for the recording of water licences again
received special attention with 107 maps, showing subdivisions, roads, railways,
watersheds, etc., being completed. Large-scale mapping of the Similkameen River
area was nearly completed.
The work load of the Licensing Division remained high during 1972, as shown
in the following reports of the General and Draughting Offices.
General Office
During 1972 the number of new applications for water licences was 1,515,
compared with 1,733 for 1971. This decrease, coupled with increased emphasis
being placed on the processing of applications and the issue of new licences, has
resulted in there being almost 300 fewer pending applications than at the end of
November 1971. This is the first reduction to have occurred since 1964.
Applications for approvals under section 7 of the Water Act, either for the use
of water for a period not exceeding 90 days or to authorize changes in and about
streams, have remained fairly constant for the last three years.
We received fewer objections to applications in 1972 than in any of the preceding four years. This may possibly be due to an increased public awareness that
objections concerning the pollution of water sources should be made to the Pollution
Control Branch, rather than to the Comptroller of Water Rights.
Applications for the amendment of existing water licences by apportionment,
transfer of appurtenancy, or change of works or purpose, have increased slightly
over last year. The number outstanding, however, has been reduced, mainly because
the number of licences issued during the year was nearly 300 more than in any
previous year.
Four hundred and eight pollution control permits have been cleared and our
findings brought to the attention of the Pollution Control Branch. During the year
an indexing system for these applications has been introduced.
The number of water-users' communities incorporated under the Water Act
now stands at 92, compared with 87 at the end of November 1971.
The enlarged data processing system referred to in our 1971 Report has proved
very satisfactory and the majority of problems with it have been overcome. From
it we have obtained much data that were not previously available to us.
Several small changes were made to the regulations under the Water Act during
the year under review. These related to the statutory time limits set out for water
licence applications which, in many cases, had been found to be impractical, and to
various sections concerning applications for licences for power purpose.
Staff changes during the year were fewer than usual; the resignation of one staff
member enabled us to promote three others and to transfer a fourth to a more
interesting position. The staff establishment now comprises one Administrative
Officer 1, two Clerks 5, three Clerks 4, three Clerks 3, two Clerks 2, two Clerks 1,
one Clerk-Stenographer 3, one Clerk-Typist 2, and one Clerk-Typist 1.

Administrative Draughting Office
The Administrative Draughting Office is staffed by a Technician 2, a Supervising Draughtsman, four Draughtsmen 1, a Clerk 5, and two Clerks 3. Main functions of this office are checking the legal status and clearing of water applications;
compiling, revising, and maintaining water rights maps; preparing plans for water
licences; clearing land applications for the Lands Service; timber sales for Forest
Service; pollution control permits for Pollution Control Branch; checking petitions
and preparing legal descriptions for improvement districts; and attending to requests
for maps and various information from our district offices, other departments of
Government, and the public.
Applications for water licences and amendments to licences received by the
Licensing Division are cleared through the Draughting Office, and a complete check
is made of the legal status of every application received. In most cases this work
entails a search of records of other departments of Government, such as Land
Registry Office, Surveyor of Taxes, Lands Service, Department of Highways, etc.
Upon completion of this work, all applications are entered on the water rights maps
and in the stream registers which together form a record of all pertinent data regarding all water licences and applications within the Province.
The Draughting Office is responsible for checking all petitions received requesting incorporation into an improvement district. Checking petitions involves
searches of records of the Land Registry Office and Surveyor of Taxes to obtain
correct property descriptions. When the petitions to incorporate an improvement
district have been checked and found correct, a plan showing all lands within the
boundaries of the proposed district is drawn up and a legal description defining the
boundaries of the district is prepared. During 1972, 12 new districts were incorporated and the boundaries of 65 districts were amended.

DISTRICT ENGINEERS DIVISION
M. L. Zirul, P.Eng., Chief of Division
Investigation of and reporting and recommending on applications for new water
licences has continued at a high level and the total number still requiring attention
at the six district offices has been reduced for the second successive year from the
number outstanding at the beginning of the period, in spite of a continued high level
of incoming new applications. The effort required to avoid losing ground in this most
important area of district office administration does restrict, to a large degree, the
attention that can be devoted to dam inspections, the undertaking of water supply
reports, and other engineering endeavours without additions to staff. Notwithstanding this limitation, a relatively large number of engineering studies are undertaken
and completed each year, administration of existing water licences, including the
resolution of conflicts, investigation of complaints involving water use or interference
with or contamination of stream flows, receives continuing attention.
During the snow-melt period, excessive run-off from the heavy snow-pack of
the preceding winter made it necessary to take all engineering staffs of Mainland
offices from their normal duties and involve them full time in the flood-fighting programme and follow-up inspections and reporting on flood damage, and assisting
agencies involved in damage assessment for the purpose of determining reparations
entitlements from the Province's Major Disaster Fund. Documentation accomplished by the District Engineers of the extent of flooding within developing areas is
expected to be of value in future land-use planning.
The active dam inspections programme and documentation of storage data,
commenced last year, has been continued at the Kelowna District Office and a start
has been made on a similar programme at the Kamloops Office.
Except for resignations of one Assistant District Engineer and one Engineering
Assistant, both at the Kamloops Office, the staff situation was relatively stable during
the year. Replacement staff has been engaged for the Kamloops vacancies and this
situation is expected to be back to normal early in the new year. Having senior district staff members with excellent experience in their field continues to be an asset
 Y 24
B.C. WATER RESOURCES SERVICE
and has enabled this Division to maintain a relatively good position in spite of
increasing responsibilities and volume of work.
District offices of the Water Rights Branch are located at Kamloops, Kelowna,
Nelson, New Westminster, Prince George, and Victoria. Each district office is in
charge of a District Engineer who is responsible for administration of the Water Act
within the several water districts under his jurisdiction. For administrative purposes,
the Province is divided into 27 water districts, based mainly on watershed areas.
The District Engineers are expected to operate relatively independently in their
administration of the Water Act. Each also holds membership on the technical
planning committees of the regional districts within his area and on various inter-
sector resource-use committees. The District Engineer at Kelowna participates in
meetings of a Public Involvement Task Force under the Okanagan Basin Agreement
and is also involved in the Wood Lake-Kalamalka Lake study group. The Prince
George District Engineer attends meetings of a Greater Prince George Area Services
Committee in an advisory capacity and represents Water Resources Service on a
Maxan Lake Resource Use study being conducted in the Burns Lake area.
Individual reports of the six District Engineers follow. The table below summarizes activities associated with water licence applications and administration of
existing licences for the 12-month report period ending October 31, 1972.

Kamloops District Office
D. E. Smuin, P.Eng., District Engineer
Climate and topography, as well as water supply and demand and purposes for
which water is used, vary widely within the region making up the Ashcroft, Cariboo,
Kamloops, and Nicola Water Districts which are administered by the Kamloops
District office. This region includes the drainage basins of the Chilcotin, Upper
Quesnel, North and South Thompson, Nicola, Coldwater, Seton, and Bridge Rivers
and constitutes a large part of the south central part of British Columbia. The Kamloops District office staff consists of a District Engineer, two Assistant District
 WATER RIGHTS BRANCH
Y 25
Engineers, a Technician, an Engineering Assistant, a Clerk-Stenographer, a Clerk
engaged on a temporary-continuous basis, and two temporary Engineering Aides.
Vacancies occurred as a result of resignations of Engineering Assistant J. D. Cummings, in August, to attend university, and of Assistant District Engineer P. E.
Anning, P.Eng., in September, to accept other employment. Recruitment is under
way and it is hoped these vacancies will be refilled by the year-end.
The weather during December 1971 and January and February 1972 was
characterized by continuing snowfall and cold temperatures. The resulting well-
above-average snow-pack in the various watersheds within the region, combined
with a cool, late spring, produced flows of flood proportions in all streams during
the snow-melt period. River-levels in most areas equalled or exceeded those recorded in the flood year of 1948 and only the occurrence of periods of cool weather
prevented more catastrophic flooding. Notwithstanding, extensive property damage
occurred in many areas. In particular, a dyke failure in a newly subdivided area
adjacent to North Kamloops, known as Oak Hills, resulted in water damage to
approximately 100 dwellings and 55 mobile homes. The above-normal run-off
provided more than ample water to storage reservoirs. Although precipitation during July, August, and September averaged only 75 per cent of normal, base flows
of most creeks were well above their long-term minimums.
An average number of water-sharing complaints was received during the year,
but these mainly resulted from inadequate works rather than shortage of water in
the source. Several flooding and erosion problems, particularly in the Nicola and
Coldwater Rivers near Merritt, required investigation.
A programme for inspection of the many small dams within our administrative
region was initiated this year, using the District Technician and an Engineering
Aide, resulting in a total of 42 dams being inspected. Because of a shortage in
engineering staff, it has not yet been possible to review the dam inspection reports
or to order repairs or other maintenance by the licensees where considered necessary.
The work load associated with the technical planning committees of the regional
districts continues to increase as the regional districts become more involved in land-
use planning. The District Engineer was appointed Vice-Chairman of the Technical
Planning Committee of the Cariboo Regional District. In addition to this involvement, a considerable amount of staff time was given to assisting improvement districts
and water-users' communities in their administrative and engineering problems.
Six engineering studies were completed this year, four of which were required
to determine whether parks proposed on or near certain Interior lakes would conflict
with future water-storage requirements.
As well as the administrative work indicated in the summary attached, the
Kamloops District office staff carried out 42 inspections of various water-storage
dams, investigated 51 complaints regarding shortages or misuse of water, made 47
miscellaneous field inspections regarding other water-use administration, sampled
the Lac Le Jeune snow course five times, maintained observation on three test wells
for Groundwater Division, and attended 56 meetings of improvement district trustees
and others.
Engineering Investigations and Projects
Assistance was given to the Improvement Districts Division in supervision of
water-supply construction projects for Clearwater and Spences Bridge Improvement
Districts and in conducting related surveys. Engineering staff provided a design and
supervised the construction of a mainline extension by the Coldwater Improvement
District to a Lands Service subdivision in the Coldwater Improvement District.

Kelowna District Office
E. D. Anthony, P.Eng., District Engineer
The Kelowna District office is responsible for the administration of the Water
Act in the Grand Forks, Princeton, Fairview, Vernon, and Revelstoke Water Districts. These districts include the Kettle, Similkameen, and Okanagan River Drainage Basins; the Shuswap River Drainage Basin above Sicamous; and that part of the
Columbia River drainage area from its confluence with the Canoe River downstream
to Arrow Lakes. The Kelowna District office administers in excess of 5,000 water
licences within this area.
Personnel of the Kelowna District office consist of a District Engineer, two
Assistant District Engineers, a Technician, an Engineering Aide, and a Clerk-
Stenographer. In addition, temporary staff are hired during the summer to conduct
final licence surveys.   There was no change in permanent staff during the past year.
The April 1 water-equivalent readings at the majority of the snow courses
within the aforementioned watersheds were the highest ever recorded. As a result,
the volume of run-off during the freshet period in the major river systems, on which
records are maintained, exceeded previous volumes. The inflow to Okanagan Lake
from April 1 to June 30 was 636,400 acre-feet, exceeding the previous maximum
recorded inflow of 579,200 acre-feet in 1948. Okanagan Lake rose to a maximum
elevation of 1,124.7 feet AMSL on June 30, 0.91 feet above normal full-pool elevation of 1,123.79 feet, and remained above the full-pool elevation until August 4.
A large number of lakeshore properties suffered flooding damage as a result of the
high-water conditions.
In spite of favourable weather conditions during the snow-melt period, flows
in the majority of streams in the area were the highest ever recorded. Flow in the
Similkameen River at Nighthawk reached a peak of 45,800 cf.s. on June 1, compared to the previously recorded maximum of 38,700 cf.s. on May 30, 1948. Approximately 12 square miles of low-lying land within the Similkameen Valley was
flooded, several farms suffered loss of land from erosion, orchards at Cawston were
inundated, and many residential properties and buildings at Princeton, Hedley,
Keremeos, and Cawston were damaged. Highway and rail access within the basin
was interrupted or restricted several times by rampaging streams. Residences and
tourist facilities along the lakeshore suffered flooding damage as a result of backing
up of Similkameen flows into Osoyoos Lake. Other complaints of flooding were
received from the Summerland, Enderby, Lumby, Sicamous, Malakwa, and Revelstoke areas.
A total of 227 water-storage reservoirs is authorized under licences in the area
administered. Of these, 118 were inspected during the year and repairs were ordered
on 90 structures. Twelve were ordered breached or rebuilt. Storage structures are
currently under construction on Haynes and McCullough Lakes near Kelowna,
Demer Creek near Enderby, Clearwater (Madden) Lake near Oliver, Columbia
River (Mica Creek Dam) near Revelstoke, and Stevenson Lake near Princeton.
No licensed storage dams failed or caused damage to public or private property as
a result of the record run-off.
Run-off during the summer period remained above average and relatively few
complaints requiring regulation of water supplies were received. A concentrated
effort to reduce the backlog of administrative and engineering problems resulted in
a total of 270 applications for water licences being processed and left only 96 still
requiring attention at the close of the report year, October 31, 1972.

In addition to the foregoing, staff of the Kelowna District office adjudicated 10
water-use disputes, attended 81 meetings of regional districts and improvement districts and other groups, sampled one snow course, prepared 86 final licence reports,
and 63 water licence amendment reports, observed 17 groundwater stations, made
95 miscellaneous field inspections, and investigated a multitude of flooding and
erosion complaints.
Engineering Investigations and Projects
Supervised installation of the water-supply system for Larkin Waterworks District near Armstrong for the Improvement Districts Engineering Division. Prepared
a profile of the proposed water-supply mainline for the Big Eddy Waterworks District near Revelstoke and a plan and profile of the existing water-supply system of the
Silver Star Waterworks District, also for Improvement Districts Division.
Prepared a report on the availability of water in the Kalamalka Lake Watershed.
Prepared a preliminary report on damage as a result of high flows in the Similkameen
River basin. Investigated and prepared reports on the feasibility of constructing
flood-control works along Armstrong Creek near Keremeos and bank protection to
correct an erosion problem on the Illecillewaet River near Revelstoke.
Nelson District Office
T. H. Oxland, P.Eng., District Engineer
The Nelson District Office administers the Water Act in the Nelson, Kaslo,
Cranbrook, Fernie, and Golden Water Districts. This area comprises some 25,000
square miles in the southeast part of British Columbia and includes the upper drainage basins of the Columbia and Kootenay Rivers.
District office personnel consist of a District Engineer, two Assistant Engineers,
a Technician, and a Clerk-Stenographer. In addition to the permanent staff, a Clerk
is retained on a temporary-continuing basis to maintain files and records, and, during
the summer months, two temporary survey personnel are employed to carry out
surveys required in water licence administration.
Stream-flow during the year was generally above normal and exceeded that of
the 1971 season. Run-off from the exceptional snow-pack of last winter caused
extensive flooding in the Columbia and Kootenay Valley bottoms, particularly within
the Town of Golden. Elsewhere in the district, high flows in smaller tributary
streams caused considerable damage to both residential and farm lands.

Complaints of local flooding arising out of the exceptional run-off required
attention; however, water-sharing disputes were minimized. Several allegations of
logging operations affecting water quality required investigation, especially where
the effects of these operations were aggravated by high stream-flows.
In addition to ordinary water licence administration, a considerable amount of
staff time was required assisting improvement districts and water-users' communities
and in attendance on the technical planning committees for three regional districts
and the Inter-Sector Committee for the Environmental and Land Use Committee.
In all, 63 of these meetings were attended during the year.
The reporting on applications for water licences was down from last year, with
262 being dealt with. The lower production resulted from demands for inspection
of flooding problems, as well as the attention to amendments to existing licences. A
total of 222 amendment applications was processed during the season.
The change-over of the office filing system, to correspond with that used at
headquarters office, was completed during the year. Except for the reorganization
of the technical and reports library, the updating of records, which started almost
two years ago, is now complete.
The bar graph included with this report extends the data contained in reports
for 1970 and 1971 and also shows reports submitted for licence amendments since
1967.
Staff reviewed the construction of a sediment-impoundment dam on Erickson
Creek in the Sparwood area. This dam, designed by consulting engineers, is intended to remove debris carried by run-off from the large strip-mining operation in
this area. The performance of this impoundment dam, as well as one constructed
last year on Harmer Creek in the same area, is under continuing review.
Several division tanks were designed by our engineering staff, with construction
being carried out by the water-users concerned. Generally, these tanks are intended
to resolve long-standing water-sharing disputes or to distribute equitably available
flow where the water source is considered fully recorded.
Inspections of two storage dams resulted in instructions being issued for the
repair and modification of the existing structures, one on Gold Creek near Cranbrook and one on Norns (Pass) Creek near Castlegar.
In co-operation with the Department of Highways, a culvert was placed at the
outlet of Lillian Lake near Invermere to control the level of the lake and maximize
recreational and wildlife use.
The drainage culvert installed in Makay-Taylor slough near Kimberley was
inspected during the freshet period and found to be performing as expected for the
prevention of local flooding.
New Westminster District Office
E. G. Harrison, P.Eng., District Engineer
The administrative area of the New Westminster District office comprises the
Vancouver and New Westminster Water Districts in the southwest part of the
Province. Most attention is required in the Lower Fraser Valley and Sechelt-Powell
River areas.
Water supplies from the streams in the area held up well in spite of a six-week
period in the last half of July and in August when practically no rainfall was registered. As a consequence, the number of complaints and disputes regarding water
shortages was minimal and most were easily resolved. This factor, and a drop in
the number of applications for water licences received, enabled the office staff to
decrease the number of applications for water licences requiring attention. The out-
 Y 30 B.C. WATER RESOURCES SERVICE
standing backlog was reduced from 238 to 166 at the end of the report year in spite
of the flood situation requiring a great deal of staff attention during the early part of
the season.
Water licences on streams in the Sunshine Coast area are receiving considerable
attention in connection with planning by the Department of Highways of the relocation of Highway 101, especially in the Gibsons bypass area. This is an important
area of study by the Technical Planning Committee of the Sunshine Coast Regional
District, of which the District Engineer for Water Rights Branch is a member.
Similar involvement is required of the Technical Planning Committee of the Squam-
ish-Lillooet Regional District, where the appointed member from this office is Vice-
Chairman. Water supply and water licensing are proving to be important aspects
involving technical planning committee recommendations to the regional districts.
Increased interest in the administration of natural resources is shown in the
objections and comments received with respect to applications for water licences,
proposed amendments to existing licences, and in connection with proposed improvements to streams. Objections were received in connection with a proposed removal
of logging debris from Alpha Lake at Whistler. On the other hand, no objections
were received to similar work being carried out in nearby Green Lake. The work in
Alpha and Green Lakes is being carried out in conjunction with the Lands and Forest
Services.
The New Westminster District office is staffed by a District Engineer, Assistant
District Engineer, Technician, two Engineering Aides, and a Clerk-Stenographer.
Previous interference with office output, due to staff vacancies, did not occur this
year.
Prince George District Office
C. E. Wilson, P.Eng., District Engineer
The Prince George District office administers the Water Act in the Prince
George, Quesnel, Peace River, Liard, Fort Fraser, Hazelton, Prince Rupert, and
Atlin Water Districts, which include the drainage basins of the Taku, Stikine, Nass,
Skeena, and Fraser Rivers draining to the Pacific, and the huge Liard and Peace
systems draining to the Arctic.
The Prince George District office staff during 1972 consisted of a District
Engineer, an Assistant District Engineer, a Technician, and a Clerk-Stenographer,
all on a permanent basis, and an Engineering Aide retained on a temporary-continuous basis. During the survey season, one student was employed to assist in the
final licence survey programme. The employment of an Engineering Aide on a
continuous basis has assisted greatly in furthering the final licence survey programme,
and the output of final licence reports was increased as a result.
The high run-off from a record snow-pack averaging some 144 per cent of the
long-term average in the north central area was aggravated by an exceptionally high
June precipitation. The water level reached on the Fraser River in Prince George
was the second highest on record, being exceeded only by the flood of 1948. Only
the operation of the Nechako Reservoir prevented the water levels in Prince George
from exceeding the 1948 levels. Precipitation for the remainder of the season was
average and only a few complaints of water shortages were received and little regulation of water diversions was required.
The Nechako River jammed with ice at its confluence with the Fraser River at
Prince George on December 18 and remained in that condition throughout the
winter. Flooding from high water levels, which persisted until January 6, necessitated a number of evacuations from the Cottonwood Island area in Prince George.
 WATER RIGHTS BRANCH
Y 31
Following additional flooding of the same area during the spring freshet, many of the
residents left the island permanently.
The backlog of applications for water licences requiring attention at the Prince
George office has been reduced to 170, down 11 from last year, due partly to a
decrease in the number of new applications received during the year. Work requirements in other areas continued to increase over last year to the point where it is
apparent an increase in staff will be required in order to keep pace.
Close liaison was maintained with the Branch's Improvement Districts Engineering Section and with improvement districts in the Prince George area, particular
attention being given to Blackburn, Pineview, Buckhorn, Nechako, Parkridge, and
Lafreniere Improvement Districts. Districts in other areas outside of Prince George
were visited a number of times regarding water supply and sewerage projects, particularly in the Hazelton area. In total, 65 meetings with improvement district
trustees were attended during the year.
Technical planning committee meetings of five of the six regional districts within
the Prince George District office administrative area were attended regularly, totalling 22 meetings. The District Engineer was appointed Chairman of the Technical
Planning Committee of the Fraser-Fort George Regional District for a third term.
He also continues to act on committees for a study of Greater Prince George area
services and for the study of the effects of resource uses on the Maxan Lake area.
Measurements of groundwater levels and of snow courses were continued for
the Groundwater and Hydrology Divisions, and a programme of stream measurements on various water-short streams was continued.
The demands on the water resource have continued to increase with the growth
in industry in the central Interior. A large mine near McLeese Lake began production this spring, and a pulp-mill at Quesnel this fall; a pulp-mill at Mackenzie is
expected to go into production in December. A renewed interest in placer-mining
is taking place in the Barkerville-Bowron Lakes area as a result of the increase in
gold prices.
There is a total of 151 dams in the area under jurisdiction, 27 of which are for
power generation. A total of 49 man-days was spent on emergency duties arising as
a result of the flood situation during the heavy run-off period. In addition, field
studies were carried out to assist in determining the effect on Nechako River flows
of natural storage on Cheslatta Lake during the period of controlled spillage of the
Nechako Reservoir. In order to record the extent of flooding within the settled
areas on many of the major streams, enlarged copies of aerial photographs were
taken into the field, and flood lines as determined by direct observation were marked
thereon. Assistance was given to the Flood Reparations Committee and the claims
adjusters appointed by the Province in their review of flood-damage claims.
An investigation was made of flooding on Tudyah Lake near McLeod Lake on
the John Hart Highway as a result of the backwater effect of Williston Lake, following that reservoir's reaching full storage level for the first time and testing of spillway
facilities.
In addition to the foregoing, investigations of flooding and erosion were made
at Foreman Flats on the Fraser River, Tabor Creek, the Salmon River near Prince
George, Bowron Lake and Bowron River, Swift Creek at Valemount, the Pine River
near Chetwynd, Charlie Lake near Fort St. John, an unnamed creek at Hudson Hope,
the Skeena River at Hazelton and at Thornhill, the Bulkley River at K'san, Thornhill Creek near Terrace, at locations within the Nechako Improvement District at
Prince George, and Red Bluff Improvement District at Quesnel.
Investigations were made of alleged erosion and settlement of the Alcan weir
on the Nautley River and possible effect on Fraser Lake, of unauthorized works on

unnamed creeks near Hazelton alleged to affect Highway 16, and the main Canadian
National Railways line, and of unauthorized works on an unnamed creek near
Hudson Hope and on Bouchie Creek near Quesnel.
A proposal to divert the McLeod River into the Pack River below McLeod
Lake was the subject of several meetings with the Department of Indian Affairs, the
Forest Service, and the Department of Highways. The proposal was dropped.
Victoria District Office
P. G. Odynsky, P.Eng., District Engineer
The Victoria District office administers the Water Act in the Victoria, Nanaimo,
and Alberni Water Districts which covered Vancouver Island, the Gulf Islands, and
adjacent islands.
The office staff during 1972 consisted of a District Engineer and one Engineering Assistant, and was augmented during the summer by the hiring of two temporary
employees to carry out final licence surveys and allied work. Facilities of the Water
Licence Division were used for clerical and stenographic requirements; one of the
temporary employees was retained on a continuing basis to assist in coping with the
increasing work load.
Within the area administered, water is used largely for domestic and industrial
supply. Inroads into agricultural use are observed to be occurring as a result of
subdivision of farm lands for suburban housing developments.
Weather throughout the Vancouver Island region varied widely during 1972.
Cold and wet winter weather, with recurring snow and rain, caused the Koksilah and
Cowichan Rivers and streams, including Craigflower Creek and others, to overflow
and wash out roads and flood homes. In February, temperatures warmed, but
frequent rain storms melted higher snows causing a recurrence of flooding. An
exceptionally severe storm which struck the Greater Victoria area on Sunday, March
5, produced one of the largest March downpours on record. The 18-hour rainfall
was reported to be 2.77 inches at Gonzales, 3.77 inches in mid-city, and 4.34 inches
at Sooke. Hundreds of homes experienced flooded basements and washed-out driveways, lawns, and gardens. Staff inspected flooding in new subdivisions in the Happy
Valley and Langford areas at the height of the storm.
The month of May proved to be the driest on record, precipitation being only
0.08 inch at the City of Victoria. June and July had high temperatures interspersed
with cool, showery periods. August to November brought the driest and mildest fall
weather on record. In spite of dry weather in the latter part of the year, complaints
of water shortages were less than average.
Flooding, which invariably occurs annually during the winter months in the
Vancouver Island region, varies from year to year with the location and intensity
of the rainstorms. From Victoria District Office records, the major areas subject to
flooding during the past eight winters have been as follows:
January-March 1972—Greater Victoria area, Cowichan and Koksilah
Rivers at Duncan.
January 1971—Cowichan River at Duncan, Nanaimo, and Langford
areas.
January 1970—Lantzville and Nanaimo areas.
January 1969—Nanoose, Nanaimo, Port Alberni, Greater Victoria.
January 1968—Extensive flooding throughout a large area ranging from
Campbell River to Courtenay, Port Alberni, Nanaimo, Duncan,
Cowichan Lake.   Greater Victoria escaped this widespread storm.

The Victoria District Engineer has established liaison with Department of Highways officials for joint inspection of new land developments involving watercourses
in an effort to recognize flood-damage potential prior to the approval of subdvision
plans and so minimize the hazard of flooding in new subdivisions.
In addition to flooding complaints, staff handled a large number of complaints
involving pollution of water supplies, water shortages, interference with stream-flows,
and unauthorized works in streams. The District Engineer attended 17 meetings of
technical planning committees of regional districts, the business of which included a
detailed review of several subdivision and zoning by-laws and applications for land-
use contracts.
The review of Pollution Control Branch permits within the Vancouver Island
region, for comment on the possibility of their effect on water sources, is a new task
that has demanded considerable staff time. In particular, an application by the City
of Port Alberni which involved the diversion of a watercourse in order to use the
stream-bed as a dump-site.
IMPROVEMENT DISTRICTS DIVISION
R. A. Pollard, P.Eng., Chief of Division
There are now 304 improvement districts incorporated under the Water Act.
During 1972 the following new districts were incorporated: Armstrong Bay Improvement District, D'Arcy Waterworks District, Deep Bay Waterworks District, Dewdney
Area Improvement District, Eagle Rock Waterworks District, East Kawkawa Lake
Improvement District, Granthams Landing Improvement District, Headquarters
Road Improvement District, Lexington Improvement District, Lillooet Riverside
Improvement District, Osprey Lake Waterworks District, Tabor Lake Improvement
District. The following districts were dissolved: Derby Dyking District, East Langley
Dyking District, Edgewood Waterworks District, Salmon River Dyking District,
Union Bay Fire Protection District, West Langley Dyking District, West Sechelt
Waterworks District.
The territorial boundaries of an improvement district and the object or objects
for which the district is incorporated are set out in its Letters Patent. Upon petition
of the trustees, the Letters Patent may be amended to include new lands within the
district or exclude land, or to include extra objects. The Letters Patent of 61 improvement districts were amended in 1972, most changes being boundary amendments.
Many districts which were originally incorporated for one purpose now have
several objects. Over 90 per cent of the districts supply domestic water; about 50
per cent fire protection; 30 per cent street-lighting; and 20 per cent irrigation water.
To a lesser extent the districts provide garbage collection, dyking and drainage,
sewers, parks, and a dozen other services.
In recent years it has been Government policy not to incorporate new districts
under the Water Act with objects other than domestic and irrigation water supply,
dyking and drainage, and land improvement, except where it is infeasible for a
municipal corporation to provide the required service. Nor has it been Government
policy to expand the objects of an existing improvement district incorporated under
 Y 34 B.C. WATER RESOURCES SERVICE
the Water Act with objects other than the foregoing, again except in special circumstances.
All improvement districts are empowered by the Water Act to raise revenue by
the levying of a tax or taxes upon one or more of a number of bases, and by the
imposition of tolls and other charges. They are also empowered to issue debentures
to obtain funds for capital purposes. In many cases, improvement districts' debentures and interest thereon are guaranteed by the Province pursuant to the Improvement Districts Assistance Loan Act. There are now $14,018,400 of such guaranteed
debentures outstanding, of which $5,130,400 are serial debentures and $8,888,000
are term debentures. Sinking funds for redemption of the term debentures are held
by the Province in the amount of $630,460. During 1972, debentures of $1,957,000
were guaranteed.
Engineering Services
The Improvement Districts Division provides a technical service to improvement districts, or communities considering incorporation as improvement districts,
throughout the Province. This service is variously concerned with domestic water-
supply schemes, irrigation projects, or drainage and sewerage works. The nature of
assistance provided falls generally into three categories, as follows:
(1) Where new schemes or rehabilitation of existing works are contemplated, an engineering investigation is required, and a preliminary
report must be prepared giving technical recommendations, cost estimates, and an assessment of the economic feasibility of the scheme.
The incorporation of an improvement district or extension of the
boundaries of an existing district are not usually recommended unless
such a study shows that the new area can be economically served. A
similar economic feasibility study is required where an existing district
proposes to take on new objects, before amendment of the Letters
Patent is recommended. The aforementioned feasibility studies may
be undertaken by the Division if the land-owners in the benefiting
area or district cannot afford to retain an engineering consultant.
Generally, the Division provides these engineering services for depressed rural areas, while in more affluent areas the benefiting landowners are required to engage a professional consulting engineer at
their expense.
(2) Once the decision to initiate a project has been made, the district
then submits plans, specifications, and details of proposed financing
methods prepared by their engineering consultants for checking and
approval. With the notable exception of water-supply projects carried
out under the Federal-Provincial ARDA programme, for whose
design and construction the Water Investigations Branch largely, and
the Improvement Districts Division and private consultants to a lesser
extent, provide engineering services, in most instances plans and
specifications for proposed works of districts are prepared by professional consulting engineers retained and paid by the district.
However, the Division's primary engineering role is to review plans,
specifications, proposals and reports of other professional engineers
prepared for non-ARDA projects of improvement districts. Frequently, details of a project are discussed with the district's consultants, and revisions or modifications recommended. Sound
engineering and economic feasibility are prerequisites to a recommendation for a Government-guaranteed loan.
 WATER RIGHTS BRANCH
Y 35
(3) In the case of non-ARDA projects, to assist certain improvement
districts where works must be installed, the financing of which will
result in economic hardship, the Division assumes full responsibility
for the engineering of a project. After having completed preliminary
surveys and investigations, the Division prepares final-design drawings, specifications, and contract documents, and provides supervision
of construction. Advice is also given to districts regarding operational
problems, or modifications and repairs to existing systems.
Throughout the year, personnel from the Division travelled extensively in the
Province, holding meetings with district trustees, organization committees, municipalities, and other groups concerned with problems of development.   About 70
improvement districts were visited regarding their administration alone.
Reports Prepared and Under Preparation
Bamfield—In 1967 the Division prepared a preliminary feasibility report on
domestic water supply to this settlement on the west coast of Vancouver Island,
which concluded that a community water system would be relatively expensive. At
the request of local residents, the Division reviewed the present situation, which is
essentially unchanged.
Barrowton Waterworks District—This small district, 10 miles south of Chilliwack, obtains domestic water by gravity from Engineers Creek on Sumas Mountain.
The dam, supply main, and sections of the distribution system are in disrepair. The
Division prepared a memorandum outlining the work necessary to rehabilitate the
system. These renewals were estimated to cost approximately $15,200.
Bates Beach (Seal Bay areas)—At the request of the Regional District of
Comox-Strathcona, the Division had previously investigated the feasibility of providing a domestic water supply to these two extensive areas north of Comox. In a
memorandum to the regional district, the Division summarized its investigations and
proposed that the areas could better be served regionally, rather than by the creation
of local improvement districts.
B.C. Fruitlands Irrigation District—Hook Ranches Ltd., a major land-owner
in the Brocklehurst area near Kamloops, requested the District to provide water and
sewer services to a proposed development for some 1,200 new houses. The Division
advised the district throughout their negotiations with the company with a view to
protecting the interests of existing water-users in the district. Furthermore, before
the 1972 freshet of the Thompson River, the Division recommended against inclusion of new lands in the district and any extension of services therefore until the
adequacy of proposed dyking had been properly appraised. The scheme is presently
in abeyance pending the outcome of a ministerial hearing under the Environment
and Land Use Act into flood protection.
Clearbrook Waterworks District—The Division investigated the circumstances
of a dispute between the improvement district and the neighbouring District Municipality of Matsqui, and prepared a memorandum recommending a solution.
Covert Irrigation District—The Division investigated an appeal over assessment
for taxation of a major land-owner in this district, 4 miles west of Grand Forks, and
prepared a comprehensive memorandum thereon.
Eagle Rock Waterworks District—This district was formed to provide domestic
water to the Spallumcheen Industrial Area bordering Highway 97, 6 miles south of
Armstrong. The Division prepared a feasibility report for the proposed water system.
 Y 36 B.C. WATER RESOURCES SERVICE
Fanny Bay Waterworks District—The domestic water system of this small district 14 miles south of Courtenay was constructed about 50 years ago to supply a
sawmill and logging camp. When the logging company suspended operations, a
group of local residents bought the system and the district was incorporated in 1963.
The system, except for new pipes in a recent subdivision, is worn out. The Division
is preparing a report on its proposed rehabilitation.
Hedley Improvement District—In May 1972 the supply portion of this district's
domestic-water system was devastated by a flood on Hedley Creek. The affected
works consisted of an intake at a concrete dam on Hedley Creek and 2 miles of 10-
inch diameter and 1.3 miles of 8-inch, wood-stave pipe, which conveyed water by
gravity along the route of an access road beside Hedley Creek, including 11 bridges,
to a distribution reservoir at the site of the old mill of the Nickel Plate Mine.
Replacement of the damaged works would have cost an estimated $95,000. In the
emergency, the district obtained a temporary supply by pumping from a sump
excavated beside Hedley Creek near the townsite. The Division prepared a preliminary report on proposed rehabilitation of the damaged water system, which
recommended abandonment of the gravity supply from Hedley Creek in favour of
a pumped supply from a drilled well near the townsite. The district has since successfully developed an excellent well source, from which water is being pumped into the
original distribution system. This work will be financed partly from approximately
$60,000 flood reparations to be paid by the Province and partly from revenues
derived from recently increased water rates.
Grand Forks Irrigation District—This large district's irrigation system, installed
in 1922, pumps water from the Kettle River and conveys it at low head via an extensive network of shallow-buried, concrete pipes and flumes. Although operable, the
system is now obsolete. Individual farmers repump for sprinkler irrigation water
delivered to their land for furrow irrigation. A new, modern system is urgently
needed if agriculture is to continue as a source of income.
The Division prepared a report on modernization of the district's works, which
concludes that the most economic and flexible source for a new irrigation and farm
domestic-water system would be groundwater, if this could be proved-up in quantity.
The report recommends that an investigation of the groundwater potential of the
area be carried out as a research project under the ARDA programme. Assuming
success in developing groundwater sources, a new pressure system for sprinkler
irrigation and domestic use to serve an 828-acre area, where irrigation water is most
urgently needed, was estimated to cost $1,100,000. Irrigation charges would be
approximately $24.50 per acre per annum.
Mountain View Waterworks District—This small district, 3 miles north of
Armstrong, operates a farm domestic-water system designed by the Division and
installed in 1971. The Division has prepared a comprehensive, "as-built" and system-operating report, including drawings.
Nechako Improvement District—This district, which stretches 7 miles along
the John Hart Highway east of Prince George, is contemplating major additions to
its water system. The Division prepared a comprehensive brief on the affairs of the
district since its inception and a memorandum-report on all the relevant administrative, technical, and financial matters involved.
Otter Lake Waterworks District—Following approval of ARDA Project 89004
to provide farm domestic water to this community near Armstrong, the district's
boundaries were enlarged to include the "R.S.M." lands. The Division prepared a
 WATER RIGHTS BRANCH
Y 37
feasibility report on proposed extension of the district's system to these new lands,
which resulted in approval of ARDA Project 89027 to serve the area.
Pemberton North Improvement District and Village oj Pemberton—At the
request of the Regional District of Squamish-Lillooet, a study was commenced for
the improvement and possible extension and integration of the water-supply systems
of the improvement district and village, which obtain domestic water by gravity from
the same intake on Pemberton Creek and use a supply pipe jointly. Due to other,
urgent work, the Division was unable to complete the assignment and suspended the
study when the village engaged a private consultant. The Division is now reviewing
a report by the consultant on the village's system.
Slocan Park Improvement District—The Division prepared an "as-built" report,
including drawings, for the domestic and irrigation water system constructed as
ARDA Project 29043.
Sorrento Waterworks District—The district was requested by a developer to
include additional lands within its boundaries and to extend its water system to serve
the area. The Division advised on the necessary draft agreement between the two
parties, but the developer finally abandoned the project.
Winter Harbour—This settlement, near the entrance to Quatsino Sound on the
west coast of Vancouver Island, comprises approximately 16 houses, a school, and
two fishing camps. Limited domestic-water supplies are obtained individually by
gravity from nearby creeks. At the request of local residents, the Division prepared
a preliminary feasibility report on a community water system. The report concluded
that the most economic source would be groundwater, if available, and recommended
test-drilling. Assuming success, a pumped supply to serve approximately 28 domestic connections and the two fishing camps was estimated to cost about $25,300.
Walhachin Waterworks District—This small district, 5 miles west of Savona,
obtains domestic water by gravity from an intake on Jimmies Creek, 2 miles from
the district. The entire supply system urgently needs rehabilitation. Previous test-
well drilling at or below Walhachin having proved unsuccessful, the present situation
was reviewed. The cost of a minimum, new system to replace the existing intake,
supply pipe-line, and distribution storage reservoir was estimated at $29,200.
Wells Improvement District—Near Barkerville, this district was incorporated
to take over the water and sewer systems owned and operated by the Cariboo Gold
Quartz Mining Co. Ltd. The extensive water-supply system is in disrepair. The
Division commenced a study on proposed rehabilitation of the water system, but
when the Cariboo Regional District retained a consultant to study sewage disposal
in Wells, the Division's waterworks study was suspended pending a decision by the
regional district to have their consultant study the water-supply problem also.
Design and Engineering Services
Clearwater Improvement District—A 5,000-foot, 6-inch diameter, AC pipe extension of the district's system was installed to serve the Wells Gray Hospital. At
the request of the Wells Gray Hospital Society, in order to obtain within the budget
a gravity supply with fire protection rather than a limited, pumped supply, the
Division designed, ordered materials for, and supervised construction under contract
of the extension, and prepared an "as-built" report with drawings. Total project
cost was $18,227, being within the estimate.
 Y 38
B.C. WATER RESOURCES SERVICE
Irvines Landing Waterworks District—In 1971 the Division set the standards
for a domestic-water system to be installed by a developer for this district on the
Sunshine Coast, and reviewed the plans and specifications therefore. This year the
Division inspected the new system after installation, and is arranging for deficiencies
to be corrected before transfer of ownership to the district.
Larkin Waterworks District—In 1972 this district, 5 miles south of Armstrong,
completed the remaining 10 per cent of ARDA Project 89003 by direct labour, with
design and supervision of construction by the Division. The system consists of two
drilled wells, each equipped with a submersible pump, a 32,400-imperial-gallon,
concrete reservoir, and 33,000 feet of pipe ranging from 2-inch diameter, Class 160
PVC to 6-inch, Class 150 AC.
Ootischenia Improvement District—The new domestic-water system to serve
this district near Castlegar, 95 per cent completed in 1971, was finished in 1972.
The system was installed by direct labour, with design and supervision of construction by the Division, at substantially less than the estimated price. Most of the
works were located on private land to minimize construction costs and to avoid installation in the Highway Department's rights-of-way. Water consumption in the
district and water levels in the well-source are being studied to determine the potential of the aquifer.
Spences Bridge Waterworks District—Since its inception this district has obtained domestic water by gravity from Murray Creek through an old, 4-inch, supply
pipe owned by and used jointly with CP Rail. Not only is this pipe reaching the end
of its useful life but also the demands of the district and other joint users have exceeded its capacity. At the request of the district, the Division designed, ordered
materials for, and supervised the installation under contract of a new, larger pipeline to replace the 4-inch. The new supply main consists of 1,900 feet of 8-inch
diameter, Dl pipe, and 1,250 feet of 8-inch and 100 feet of 6-inch AC pipe, and
cost $27,917 in place, slightly exceeding the estimate.
Village oj Fort Nelson—At the request of the Lands Service, the Division designed, prepared plans, specifications, and contract documents for, requisitioned
materials for, and, assisted by staff of the Prince George District Engineer's Office
of the Water Rights Branch, supervised the installation under contract of water and
sewer system extensions to serve a 90-lot Crown subdivision in the village. Total
cost of these extensions was approximately $114,000.
Inspection of ARDA Systems
In the Federal-Provincial Agricultural and Rural Development Agreement
under the Agricultural Rehabilitation and Development (British Columbia) Act,
the Province assumes responsibility for the proper operation and maintenance of all
works constructed in ARDA programmes. In January 1972 the Division was
assigned to inspect the ARDA systems completed by improvement districts in British
Columbia and to investigate the affairs of these districts to ensure compliance with the
intent of the Act. J. W. Webber has been appointed ARDA Supervisor—Improvement Districts, to head up a section of the Division to implement this inspection
programme, for which additional staff will be required.
Routine inspections of the ARDA system of the following districts have been
completed: Canyon Waterworks District, Grandview Waterworks District, Kaleden
Irrigation District, Otter Lake Waterworks District, and Wood Lake Improvement
District.

In addition, the section has been actively investigating administrative and technical problems in the following districts: Canyon Waterworks District, re subdivision; Kaleden Irrigation District, re subdivision; Larkin Waterworks District, re
inadequate service to high land; Naramata Irrigation District, re boundary extensions
for subdivisions; Peachland Irrigation District, re taxes and tolls; Slocan Park Improvement District, re pipe-line rights-of-way; Wood Lake Improvement District, re

POWER AND MAJOR LICENCES DIVISION
H. M. Hunt, P.Eng., Chief of Division
The Kootenay Canal Plant project has been a matter of major concern to the
Division during 1972. Although project construction was well under way prior to
the start of the report year, negotiations were continued into 1972 relating to the
integrated power benefits which will be derived from the Kootenay Canal Plant.
These negotiations, leading to an agreement among Cominco/West Kootenay Power
and Light, British Columbia Hydro and Power Authority, and the Province, have
been quite protracted owing to the complexity and ramifications of the problem.
Libby Reservoir preparations have proceeded satisfactorily, although property
acquisition has tended to be slow. A partial reservoir fill was observed by Divisional
staff in 1972 to a level some 54 feet below final full pool; this was followed by a rapid
drawdown to facilitate construction of certain remedial works in the United States.
Final preparations required by the Columbia River Treaty will be made prior to the
1973 freshet.
Programmes of construction at Mica Project and the Whatshan Redevelopment
continued satisfactorily, the latter plant (50 mw.) being placed on line in December.
During the period, Units 6, 7, and 8 were placed in service at G. M. Shrum Powerhouse on the Peace River.
The programme of inspection of existing dams throughout the Province was
maintained with the object of ensuring that all major impoundments are in a safe
condition. These regular inspections are conducted in conjunction with the district
offices.
Power Licence Administration
It should be noted that, in addition to the following report, the Annual Review
oj Power in British Columbia, dated July 1972, provides further details on power
developments and should be referred to where noted.
Power Licence Applications
The only noteworthy power application dealt with during the past year was for
the development of 2,610,000 kw. at Mica Dam on the Columbia. This will be
generated from a total of six units at 435 mw. each, of which the first two will be
installed in 1976. The storage dam had already been licensed for that purpose in
1962.
Approval oj Plans
Review of plans and construction progress concerning major water licence applications and approvals, particularly those dealing with power developments, is undertaken for the Comptroller of Water Rights by this Division. During 1972, such
projects included W. A. C. Bennett Dam, Mica Dam, Whatshan and Kootenay Canal
Plant projects, as well as other smaller projects. To assure the Comptroller that
these projects were being constructed in accordance with approved plans, Divisional
staff visited Mica project, and Kootenay Canal Plant twice each during the past year,
and made visits to several smaller projects to ensure that rehabilitation or reconstruction work required by the Division was being carried out according to approved
plans. Work was progressing favourably on both Mica and Kootenay Canal projects. Mica Dam is now about 95 per cent complete, while Kootenay Canal Plant
is about 24 per cent complete. On the Peace River Development, Units 6, 7, and 8
(227 mw. each) were installed in the G. M. Shrum Powerhouse.   Contracts were
 WATER RIGHTS BRANCH
Y 43
awarded to Russian and Japanese manufacturers for the first four 595,000-h.p.
turbines at Mica Powerhouse, while the matching 435-mw. generators will be built
by a Canadian company. The British Columbia Hydro and Power Authority commenced excavation for the canal and powerhouse at the Kootenay Canal Plant and
completed an access bridge across the river just upstream from Cominco's South
Slocan Plant. The Authority's Whatsan Plant was rebuilt to a capacity of 50 megawatts and re-entered service in December 1972.
A more detailed report on the construction progress of the major projects
named above appeared in the 1972 Annual Review oj Power in British Columbia.

The administration of all major power licence rentals is supervised by this
Division, while billing is done with computer assistance. A tabulation of rentals,

Flood Control at Major Hydro-electric Power Reservoirs
General
During 1972 the Province experienced perhaps the most widespread flood
threat in its history. Major disasters were, with one significant exception at Kamloops, prevented by the various large water reservoirs and dyking systems strategically located throughout the Province.
It was realized early in March that a serious situation was developing, and the
co-operation of many other agencies was sought by the Division to assist in solving
the problem. Among those particularly concerned with optimizing the operation of
reservoirs were ALCAN Limited and the British Columbia Hydro and Power Authority, which reservoirs had been constructed for hydro-electric power purposes.
In general, flood-control reservoirs, if available, can be considered to fall into
three principal categories, though some may have elements of more than one; these
are—
(a) "anticipatory," being storage that, due to its remoteness from flood-
damage areas and corresponding time lag in achieving full effectiveness, must be operated to a pre-planned programme often well in
advance of the flood;
 Y 44 B.C. WATER RESOURCES SERVICE
(b) "flexible," being storage that can be manipulated successfully during
the course of a flood to improve its effectiveness; and
(c) "emergency," being local storage that is reserved for a last-ditch effort
to prevent or relieve a rapidly deteriorating situation.
Fraser River Basin
Apart from the Thompson River Sub-basin, the Fraser River Basin is provided
with hydro-electric power reservoirs, which, with co-operation of the owners and
accepting certain power losses, could provide flood-control storage of a significant
magnitude. Specifically, ALCAN's Nechako Reservoir can provide anticipatory
storage, British Columbia Hydro's two Bridge River Reservoirs (Downton and
Carpenter Lakes) could provide flexible storage, and British Columbia Hydro's
Stave Reservoir could be held in reserve as emergency storage, accepting certain
losses in power generation.
At the start of the 1972 run-off season it was felt that the Nechako Reservoir
was at a higher level than desired and that some pre-flood drawdown should be
undertaken. Due to ice jams at Prince George it was not possible to start until
April 13, when a spill of 12,500 cf.s. (an increase of 10,000 cf.s.) was released
at Skins Lake spillway. This was continued until May 10 and had the effect of
lowering the reservoir by 2 feet more than would otherwise have occurred. As
natural flows were stable during this period, a unique opportunity was presented for
observing the rate of travel of a sudden increase in flow.
The dash-pot effect of Cheslatta Lake, downstream of Skins Lake spillway of
Nechako Reservoir, in smoothing and retarding the wave front as it passed downstream was most pronounced. While first signs of the sudden increase in discharge
from the spillway on April 13 were not observed at Isle Pierre gauge at Nechako
River for 55 hours, river flow increased uniformly thereafter for about three weeks
until the total flow increment of 10,000 cf.s. was being passed.
It was anticipated that the flood would peak out on or about June 1. Accordingly, the spillway gates were closed by ALCAN on May 11 at the request of the
Comptroller of Water Rights. Owing to the rising local inflow downstream from
the spillway, however, observations on rate of transmission down the river of the
sudden drop in discharge were less well defined. Full co-operation received from
ALCAN is recognized.
Both Downton and Carpenter Reservoirs on Bridge River were empty ahead of
time, and the entire storage space was available for flood control. As a possible
emergency measure it was arranged with British Columbia Hydro that partial closure
of the power plant would be effected in order to reduce flows into the lower Fraser
River even further. Because these reservoirs are not too far removed from the
Lower Mainland area, and there are no intervening lakes, their storage comes in the
flexible category.
Stave River Reservoir, being very close to Mission in the Lower Mainland,
was held in reserve for emergency use. The top 6 feet, which would normally be
allowed to fill, was retained drawndown for flood control until the peak was imminent. British Columbia Hydro and Power Authority fully responded to the Water
Resources Service requests for flood-control manipulation.
The general course of the 1972 freshet on the Fraser River started out in a
somewhat similar manner to that of 1948; however, in mid-May a more gradual
rise was evident and on June 8 it was concluded (erroneously, as it turned out) that
the peak was past and that the threat of flooding was over. In an unexpected turn
of events, the Province was subjected to very heavy rains, ranging in some parts up
 WATER RIGHTS BRANCH
Y 45
to 3 inches in three days. The effect of these upon a well-primed snow-pack was very
close to disastrous. Kamloops, already the scene of a dyke failure, was very seriously threatened, but managed to escape by inches. In Prince George the low-lying
area, known as Cottonwood Island, was completely inundated; on June 14 the
Branch's District Engineer and assistant toured the area by canoe, and reported that
the water was 15 inches over the top of the dykes. The peak at Prince George
occurred at 8 a.m. on June 15, and from then on flows receded rapidly for a week.
At Mission the peak occurred on June 17. During the final four days, emergency
storage was called into use and Stave, Ruskin, and Bridge power plants were cut
back to spinning reserve. To accomplish this, British Columbia Hydro were obliged
to fire up the Burrard thermal plant in order to replace the lost generation.
On June 18 it was concluded (this time correctly) that the peak had passed;
however, there were still many problem areas throughout the Province and a close
watch was maintained for some time thereafter.
The cumulative effect of all the storage operations has not been completely
assessed as yet, but it is believed that the flow reduction at Hope was around 40,000
cf.s. A true perspective of the flood threat will be reached by appreciating that the
total volume of run-off between April and September at Hope was 72,750,000
acre-feet or 8 per cent greater than that in the same period of 1948 when an estimated $20 million of damage was caused in the Lower Fraser Valley.
Columbia River Basin
At the outset it was felt that the Columbia Basin was adequately protected.
This turned out to be correct in spite of the fact that it was subjected to the worst
flood of the century. During the latter half of June the situation appeared critical
as hydro-electric power reservoirs approached maximum levels, but, fortunately,
inflows stabilized.
The Columbia Treaty storages were operated initially for control in the United
States where peak storages were reached two weeks earlier than in Canada. Thereafter, it was possible to control the Arrow Lakes Reservoir for the benefit of Trail,
and this was done with a good measure of success. It was also most fortunate that
Libby Dam in the United States was brought into partial operation for the first
time.
Libby and Duncan Reservoirs are both in the anticipatory category for flood-
control purposes and were operated to minimum release during the peak. Arrow
storage is considered to be flexible both for United States and Canadian purposes.
It is also possible to use some surcharge at Arrow for emergency control; but this
was not needed.
The snow-melt in the Columbia Basin usually occurs two or three weeks behind
that in the Fraser Basin. The Province-wide heavy rains of mid-June therefore fell
on a ripe snow-pack, causing considerable alarm. Arrow Reservoir was 10 feet
below full pool at the time and it was decided to hold it at that level and retain the
space for the expected peak. By careful manipulation it was possible to control the
flow at Trail so that only minimal damage was experienced. By the end of June it
was evident that the danger period had passed and Arrow Reservoir was allowed to
fill in a normal fashion.
Peace River Basin
Lake Williston was well below full pool at the start of the spring run-off so little
trouble was anticipated.   The reservoir did in fact fill and a considerable quantity of
 Y 46
B.C. WATER RESOURCES SERVICE
water was spilled. The beneficial effects of this regulation were felt at a number of
down-stream communities in the Province and in Alberta, as the volume of run-off
was among the highest of record.
Generation and Load Growth
Interim Estimate jor Past Year
Duing 1972, Provincial electric-power requirements grew at a normal rate, and
the results of a quick year-end survey are tabulated below. It will be noted, from
the tabulation, that the rate of load growth for the whole Province is 8 per cent; this
is slightly above the long-term (1930-70) average of 7.65 per cent.
The generation data, which must be considered provisional, are expressed in
gigawatt-hours (gwh.) or millions of kilowatt-hours.

Long-term Growth
A 10-year analysis of growth in electric power requirements appears in the
Annual Review oj Power in British Columbia. For the period 1961—71, the mean
annual rates of growth were: Total generated, 7.92 per cent; total required within
British Columbia, 7.85 per cent. The difference in the two growth rates is due to
imports and exports which vary substantially from year to year, but which indicate
a growth in over-all net export over the period.
A graph showing peak and average energy requirements from 1930 to date
is included herein, and it will be noted that, on the average, a fairly constant rate of
growth has been maintained since 1955.
Future Power Development
Undeveloped Hydro Power-sites
A summary of known undeveloped power-sites appears in Table V of the 1972
Annual Review oj Power in British Columbia. As the data were compiled from
reports dating back, in some cases, to the 1920's, they should not be regarded as
definitive nor as more than a long-range planning aid. In most cases no environmental impact studies have been carried out and, therefore, economic feasibility of
a site has not been established. A detailed listing of the more desirable sites in the
Province appeared in the consultant's report to the British Columbia Energy Board,
in connection with its recent Provincial Power Study.

Dam Inspection
During 1972 the dam-inspection programme, instituted in 1967, was continued
and a total of nine field trips was made. Twenty-eight major dams were inspected
for adequacy and safety, as well as four smaller structures. Of these, Mica Dam
and McCulloch Dam were inspected while under construction to ensure compliance
with the previously approved plans. Other dams recently completed, such as Bulman
Dam, Fish Hawk Dam, and Peachland Dam, were inspected to ensure that their
initial operation had proceeded satisfactorily and without incident. Most of the
remaining visits were made as part of the continuing schedule of inspections to
ensure that adequate maintenance was being carried out and that no adverse conditions had developed. As a result of these inspections, recommendations were made
to the owners of several of the dams concerning improvements in maintenance practices, and rehabilitation work was inspected at one dam. Follow-up visits were
made to ensure that the rehabilitation was being properly implemented.
In addition to the inspection of the structures in the field, a continuing programme of studies was followed in the office, during which various aspects of dam
safety were investigated, such as dam stability, flood-handling capability, and reservoir-bank stability. Also, during 1972, further work was done on a study of instrumentation techniques applicable to large dams with a view to establishing minimum
standards for new construction.

and Light Co. Ltd. concerning the installation and operation of the Canal Plant on
the Kootenay River below Corra Linn Dam, and the allocation of benefits from
Libby and Duncan storages to this plant.
Columbia River Treaty
Permanent Engineering Board
The Power and Major Licences Division is responsible for providing technical
support to British Columbia membership on the Permanent Engineering Board of
the Columbia River Treaty. Among the several functions required under the terms
of the treaty, the Board has to report to the Governments of Canada and the United
States of America on progress being achieved under the treaty, to assist in reconciling differences between the development agencies of the two nations (termed the
"Entities"), and to assemble flow records of the Columbia and Kootenay Rivers at
the International Boundary.
The Chief of the Power and Major Licences Division is the nominated alternate member to A. F. Paget, who retired from the position of Deputy Minister of
Water Resources in 1969 and who is one of the two members representing Canada.
Responsibilities of the alternate member include assisting the member in the performance of his duties and taking his place at Board meetings in his absence. In
addition, the Chief of the Division is a member of the Permanent Engineering Board
Committee, whose function is to assist the Board in considering proposals and operating plans received from the Entities.
The Division Chief attended two meetings of the Board during 1972 and participated in an inspection tour of facilities under construction, which included Mica
Dam, Libby Dam, as well as a visit to the Third Powerhouse at Grand Coulee in
Washington. A joint meeting with the Canadian and United States Entities in
Victoria was also attended.
Libby Reservoir
On January 27, 1966, the United States exercised its option under the Columbia
River Treaty to commence construction of Libby Dam on the Kootenai River near
Libby, Mont. The schedule attached to the January 1966 exchange of notes and
the terms of Article XII of the treaty require the project to be in operation by June
30, 1973, Canada is responsible for providing the reservoir area in Canada and this
task is being undertaken by several departments of the Provincial Government, with
the over-all work being co-ordinated by the Deputy Minister of British Columbia
Water Resources Service.
Partial filling of the reservoir up to elevation 2405 commenced in April 1972
and filling to full pool elevation of 2459 is scheduled to commence in the spring of
1973.
Negotiations for the acquisition of privately owned property have been progressing rather slowly owing to owner resistance to settlement. Of the total of 7,900
acres of private property to be acquired by the Government, some 6,250 acres or 79
per cent have been purchased to date. Expropriation proceedings must be instituted
to ensure completion on schedule.
The British Columbia Forest Service has now cleared completely 9,100 acres
or 98 per cent of the estimated 9,240 acres of forested land. A Forest Service machine crew of up to 18 men has been engaged in piling and burning of debris around
the perimeter of the reservoir following recent reservoir drawdown, and it is expected that most of the debris will be disposed of by the spring of 1973.
 WATER RIGHTS BRANCH

The 29 miles of new roads necessitated by the flooding are now complete. The
Kikomun bridge and the Gold Creek bridge were opened to traffic in June, while the
Wardner Highway bridge and the Canadian Pacific Railway overpass at Wardner
were opened to traffic in October.
A joint study by the Government of British Columbia and Canadian Pacific to
evaluate compensation for track modifications between Fort Steele and Wardner,
made necessary by the reservoir, was undertaken; and it is anticipated that the track
work will be completed prior to the 1973 freshet.
Preliminary designs of three water-fowl holding-ponds at Wardner are complete
and, if the area selected is found to be suitable for retaining water following the
spring freshet, the first pond will be constructed in the summer of 1973.
Parks Branch planners of the Department of Recreation and Conservation have
been working on a limited-use facility with boat-launching ramp in the Wardner
waterfront area and have also gone ahead with the development of a 1,390-acre park
south of Kikomun Creek. By the summer of 1973 they expect to have a fairly
extensive day-use beach and a 50-unit campground in operation at the mouth of
Kikomun Creek.
A meeting was held on December 14, 1972, in Victoria with representatives of
the United States Corps of Engineers, the authority responsible for construction of
Libby Dam and reservoir preparation in Montana, to discuss progress and items of
common interest and concern.
  WATER
INVESTIGATIONS
BRANCH
The Water Investigations Branch was formed in late 1962 as a consequence of the creation
of an independent British Columbia Water Resources Service.
The functions of the Water Investigations Branch, which is headed by the Chief Engineer,
are to deal with technical matters pertaining to the water resources of the Province not directly
connected with the administration of the Water Act and the Pollution Control Act, 1967. These
functions, carried out by various divisions of the Water Investigations Branch, are briefly summarized below.
(1) Water Supply and Investigations Division:
(a) Irrigation and domestic water-supply investigations to assist and advise in
the development and maintenance of water-supply projects.
(6) Surveys and mapping in connection with water-resource planning, investigations, and construction.
(2) Hydrology Division:
(a) Snow surveys and snow-melt run-off forecasting to guide judicious utilization
of water supply.
{b) Hydrologic studies of the Province to compile and evaluate basic hydro-
meteorological data for use in planning, engineering studies, and related purposes.
(3) Groundwater Division: Collection of existing groundwater data and investigation and
evaluation of groundwater potential to encourage and guide the future use and conservation of this source of water supply.
(4) Basin Planning and Power Division:
(a) Development of plans for water conservation and management on a regional
basis.
(b) Investigation and inventory of undeveloped hydro-electric power potential of
the Province.
(5) ARDA Division: Processing of water-project proposals made under the Agricultural
and Rural Development Act, and investigation, design, and supervision of projects.
(6) Projects Division:
(a) Flooding, drainage, and stream-erosion investigations to give engineering
advice and assistance in solving water-damage problems.
(b) Implementation of projects under the Canada-British Columbia Fraser River
Flood Control Agreement.
(7) Ecology Division: To undertake and direct limnological and ecological surveys in
connection with water-resource planning, investigations, and development projects.
(8) The above divisions are supported by a Draughting Office and a Records Compilation
and Reports Section.
The above functions are carried out in co-operation with a number of other Governmental
agencies with an aim to enable the British Columbia Water Resources Service foster better use
of water resource, which is one of the principal physical foundations of the economic development of the Province.

INVESTIGATIONS
BRANCH
B. E. Marr, P.Eng.
Chief Engineer
The Water Investigations Branch was created in December 1962, and deals
with technical matters related to the water resources of the Province, which matters
are not directly connected with the administration of the Water Act and the Pollution
Control Act, 1967.
To carry out Branch functions, seven divisions have been formed and a detailed
account of their activities in 1972 is given in the following pages. Also included
are reports on the operation of the Draughting Office, Records Compilation and
Reports Section, and the Reports Library. The latter two offices also perform certain services for the other branches of the Water Resources Service.
The increased work load and responsibilities assumed by the Branch during the
year necessitated certain organizational changes. A new position of Assistant Chief
Engineer (Technical) was created and filled by P. M. Brady, former Chief, Projects
Division. J. D. C. Fuller transferred from Chief, ARDA Division, to head up the
Projects Division, and J. V. Eby became Chief, ARDA Division.
In December the Branch assumed increased responsibility under the Fraser
River Flood Control (1968) Agreement and is now responsible for the design and
construction phases of the programme. The Fraser River Joint Programme Committee has been disbanded and the Programme Director and his staff have been transferred from New Westminster to Victoria and will be absorbed into the Projects
Division.
Under the Fraser River Flood-control Programme, applications for participation have been received from 17 local authorities. Of these, two are under construction, the Districts of Kent and Matsqui, with a total estimated cost of approximately
$5,000,000. In the case of four projects, those for the Districts of Pitt Meadows,
Richmond, Chilliwhack, and Delta, project reports are complete, including preliminary design and cost estimates and these projects, with a total estimated cost of
$30,000,000, are ready to proceed as soon as the local authority enters into an agreement with the Province. Also, a section of the District of Surrey project involving
rehabilitation of the Nicomekl and Serpentine River Dams, considered to be emergency work, could go to contract immediately upon signing of the local agreement.
Under the terms of the Fraser River Flood Control Agreement, it is required
that a review of the programme of upstream storage set out in the 1963 Final Report
oj the Fraser River Board on Flood Control and Hydro-electric Power in the Fraser
River Basin be carried out, including any additional measures, with a view to recommending further flood protection, utilization, and control of the water resources of
the basin. Among other responsibilities delegated to the Water Investigations
Branch is the re-evaluation of the ecological impact on all resource-users, of the
upstream storage proposals.   In September 1970 a committee was formed to under-
53
 Y 54 B.C. WATER RESOURCES SERVICE
take these ecological studies. This committee is comprised of seven branches of
Government, both Federal and Provincial, and is carrying out its assignment through
the following studies:
(1) To assess the existing and potential mines in reservoir areas, and
economic effects of flooding on the existing and potential mines:
(2) To review the timber inventory and analyze the impact of flooding
on forest management and operations:
(3) To evaluate present and projected social and economic outdoor
recreational values of affected areas
(a) in their present and undammed state; and
(b) with the establishment of the proposed dams:
(4) To determine the benefits and disbenefits to wildlife resources of
System E flood storage proposals:
(5) To determine the benefits and disbenefits to fresh-water sport fishery
resources of System E flood storage proposals:
(6) To determine the effects upon anadromous fish populations in tidal
and nontidal waters resulting from System E flood storage proposals
and to evaluate the potential biological changes in the intertidal and
lower areas of the estuary, including much of the Gulf of Georgia:
(7) To prepare an analysis of Canada's commitments to the United States
under the International Pacific Salmon Fisheries Commission Treaty:
(8) To prepare an economic analysis of System E flood storage proposals
as it affects the anadromous fisheries resources:
(9) To assess the loss of agricultural production in flooded areas and the
benefits from potential production of farm lands irrigable from the
reservoirs:
(10) To assess farm-land benefits to be derived in the Lower Fraser Valley,
in areas outside dykes, due to upstream storage.
The Okanagan Basin Study is now entering its final stage with the final report
scheduled for completion in late 1973. A number of bulletins have been published
outlining progress to date on the various aspects of the study and the public involvement programme is now getting into full gear with the formation of a number of
task forces, including representation from the various interest groups in the Okanagan
Valley. This will allow the planning process to be responsive to the wishes of the
people of the area as called for under the Canada-British Columbia Okanagan Basin
Agreement. A special study group has been set up under T. A. J. Leach, Assistant
Chief Engineer (Administration), to carry out these aspects of the study assigned to
the Branch, and the present status of the study is outlined in the Assistant Chief
Engineer's report.
The Hydrology Division now operates 210 snow courses throughout the
Province and these gave early indication of record or near record accumulation of
snow in 1972. Warning of potential flooding was given in the Snow Survey Bulletins
published by the Branch for the Okanagan, Similkameen, Kettle, Thompson, Fraser,
Upper Kootenay, and Upper Columbia regions. Advance warning of possible flood
conditions alerted the various responsible agencies and allowed pre-planning of
emergency measures. Examples of action taken include storage of water on the
Nechako Reservoir, which materially reduced flood levels in the Lower Fraser Valley
and operation of the Okanagan flood-control works to reduce flood losses in the
Okanagan Valley.   The co-operation of the Water Survey of Canada and the At-
 WATER INVESTIGATIONS BRANCH
Y 55
mospheric Environment Service is acknowledged in providing stream-flow and
weather information.
The high run-off in 1972 caused flooding and erosion problems at a number of
locations throughout the Province, including the Kamloops area and the Similkameen
Valley. A large number of problem areas was inspected by Branch staff and, in a
number of cases, assistance was given in the design and construction of flood-control
works.
The Branch continues to be involved in water projects under the Federal-
Provincial ARDA programme (Agricultural and Rural Development Act). Since
the start of this programme in 1963, a total expenditure of $34,200,000 has been
authorized and some $31,000,000 actually expended on approved ARDA water
projects. A total of 49 projects has been completed and 14 are under construction.
Projects essentially completed during 1972 include the Kaleden Irrigation District,
Keremeos Irrigation District, Vernon Irrigation District, Otter Lake Waterworks
District, Peachland Irrigation District, and Westbank Irrigation District.
In 1971 the Branch was assigned the management of the construction of the
Squamish River training works on behalf of British Columbia Railway. This work
was carried out by consultants and involved the extension of the flood-control dyke
previously designed and constructed by the Branch, dredging of a new river channel,
and the completion of the dyke and timber-pile wall guide. The training dyke forms
part of a proposed harbour development and the cost of construction was approximately $2,000,000.
Work continued on the mapping of existing and potential major water-storage
sites to provide basic data for water-planning purposes. It is intended to train the
survey crews to include water-quality sampling in future bathometric survey programmes. The surveys to date have been mainly concentrated in the Okanagan
and Similkameen watershed. The survey crews were also busy in 1972 collecting
information in flooded areas during the peak run-off period, and this included establishing flood profiles, determining stream velocities, and defining the flood plain. It
is anticipated that flood-plain mapping will become of increasing importance in the
future.
A task force has been appointed under the Environmental and Land Use Technical Committee to investigate practicability of obtaining wholesome water supply
from streams the watersheds of which are subject to multiple use and to recommend
policy and procedures for consideration of such land-use conflicts. Background
information is being collected in support of the task force and, in late 1972, a
questionnaire was distributed to the operators of all public waterworks systems in
the Province to select their views on multiple use of their watersheds and any conflicts of which they are aware.
Work continued on the inventory of the undeveloped water-power potential of
the Province, including the Liard River system. In connection with the Fraser River
Flood Control Agreement, field investigations were carried out, including drilling
and seismic exploration to prove-up the feasibility of two possible storage-sites
included under System E of the Fraser River 1963 Final Report. These are the
Lower McGregor River project and the Hemp Creek project on the Clearwater
River system. In the case of the McGregor site, further exploration is being carried
out by the British Columbia Hydro and Power Authority, and good co-ordination
was maintained by the two agencies to avoid duplication of effort.
The programme of collecting groundwater data continues, and this information
is much used by other agencies.  The procedures for storage and retrieval of data
 Y 56 B.C. WATER RESOURCES SERVICE
were improved during this year and it is hoped to make further improvements in this
area.
As part of the study of the hydro-geology of the Gulf Islands initiated in 1971,
it was decided to undertake an intensive programme of groundwater investigation on
Mayne and Gabriola Islands to develop techniques for assessing this important water
source, and this work is now well under way.
Studies have been initiated into the biology of aquatic weeds and data have
been collected from Windermere Lake, the Okanagan lakes, and selected small lakes
in the Victoria area. These studies are oriented toward possible methods of controlling this nuisance and were initiated following complaints received from various
parts of the Province.
The major interdisciplinary study of the Kalamalka-Wood Lake Basin continues and is reported on in a later section of this report. This study involves staff
members from the various divisions of the Branch as well as outside consultants.
This trend toward a multidiscipline approach to water-management problems has
been steadily increasing in recent years and is expected to continue. It can be
noted in the Fraser River Upstream Storage studies, the Okanagan Basin Study, the
Task Force on Multiple Use of Watersheds, and internal studies such as the Kalamalka-Wood Lake Basin. It is also noted that the Branch has been involved in
an advisory role on other such studies, including the proposed Squamish River harbour development. The Branch has also been involved in reviewing applications for
Crown land purchases, leases, and reserves to determine possible water-resource
management conflicts.
The Branch acknowledges the assistance received during the year from other
Government specialists and outside services in the carrying-out of its functions in
the investigation, planning, and development of the Provincial water resources. Special mention is made of the continued co-operation with the Civil Engineering
Department of the University of British Columbia, the British Columbia Research
Council, and the University of Waterloo.
Senior members of the Water Investigations Branch continued to participate in
a number of committees dealing with water-resource matters, including ARDA committees, the National, Provincial, and Screening Committee for the International
Hydrological Decade, the IHD Hydrology Subcommittee of the National Research
Council, Co-ordinating Committee for Hydrometeorological Networks, the Board
and committee in connection with the Fraser River Flood Control Agreement, Land
Use Working Committee, Mines Reclamation Act Technical Committee, Sea Use
Council, and the Task Force on Multiple Use of Community Water Supply.
At year-end the Water Investigations Branch staff consisted of 66 permanent
and 63 continuous temporary positions. Among these, there were 37 Civil Engineers,
four Geological Engineers, one Hydrometeorologist, and three Biologists. There
were three vacant positions.

During the latter part of February 1972, Seminar of Study personnel met in
Vancouver to discuss preliminary findings. This was followed by a public seminar
in Naramata held on March 24 and 25, 1972, where panel discussions on the major
studies took place.
The need for a continuing flow of information to the public became evident
at the Naramata meeting and in an effort to provide a portion of this, members of
the Water Investigations Branch undertook three one-day seminars in the valley
at Osoyoos, Kelowna, and Vernon during May 1972. While the discussions were
essentially on water-quantity problems, some additional questions on water quality
were referred back to the Pollution Control Branch. The questions and answers
from these three seminars have been prepared for public distribution as part of the
Public Involvement Programme (PIP).
The PIP Consultant and his staff have been very active in the valley in organizing public meetings and arranging for the formation of task forces consisting of
interested citizens who are prepared to carry out "in-depth" studies on a co-operative
basis during this winter. In order to assist these local groups, a number of task
reports have been made available to them as well as the local libraries. Much of
this information is also being provided through the local television stations, radio
stations (including "hot lines"), and the newspapers. It has been found that considerable time and effort are required by key study personnel in presenting to the
public the alternatives available. This type of participation will probably increase
during the coming months and, while highly desirable, it does reduce the office time
available for ongoing studies which already have very tight completion schedules.
The Water Investigations Branch, as the responsible agency for water-quantity
studies, completed the field work this year and is continuing its office studies as
follows:
Water-quantity Studies
Description oj Area
The two main sources of water supply for the Okanagan Basin are the tributaries
which provide about one-third of the total present-day water requirements, while
the remaining two-thirds are served from the main-stem lakes and rivers extending
from Okanagan Lake downstream to Osoyoos Lake. Present-day water requirements with respect to the tributaries are those required to meet agriculture, domestic,
and municipal purposes. In the case of the main-stem lakes and rivers, the requirements also include minimum "in-channel flow" needed for intake submergence,
fisheries, aesthetics, and recreation.
Details of the basin are given in the 1971 Annual Report, while a plan is enclosed here under tributary studies (Fig. 1).

Reconnaissance Hydrometric Surveys
Because of the potential flood hazard indicated from snow-survey information
early in the year, a reconnaissance hydrometric survey was arranged with the Water
Survey of Canada with the objective of making selected stream-flow measurements
before, during, and after the freshet. The information from this survey is now
being checked again at semi-empirical approach for the determination of tributary
run-off using latitude, valley precipitation, and limited run-off records as described
under tributary studies. The work was started in the latter part of May and ran
through to September.
1972 Flood
It is evident from the tabulation below that during the period April to September, inclusive, a record inflow occurred in Okanagan Lake as well as in the adjacent
Similkameen River Basin immediately to the west.

water occurred on June 29, 1972.
Peak elevation of Osoyoos Lake occurred on
June 3, 1972, at 917.0 (USCGS), while Similkameen River at Nighthawk peaked on
June 1, 1972 at 45,800 cf.s.
Thus, the previous 1948 record flood was exceeded by some 11 per cent in the
Okanagan and by 8 per cent in the Similkameen. Details of the flood are described
later in this report.
Main-stem Water-quantity Model
It has been possible to compute the monthly net inflows to Okanagan Lake for
the 50-year study period (1921-70) and expand this through correlations downstream to include flows at Okanagan Falls and Oliver. Further, through a study of
consumptive use over the above-mentioned 50-year period coupled with lake evaporation estimates based on air temperatures, to arrive at the gross inflow to the main-
stem lakes.
It has been estimated, using the grid-square method, that the average precipitation occurring over Okanagan Lake Basin (where about 80 to 90 per cent of the
basin inflow originates) is some 22 inches. The resulting gross run-off is only 5.5
inches, equivalent to a volume of 690,000 acre-feet. After deducting for consumptive
use within the tributaries, the residual inflow into Okanagan Lake is some 600,000
acre-feet. About 40 per cent of this water is lost through evaporation from Okanagan Lake, leaving about 355,000 acre-feet available for water requirements around
the lake and downstream along the Okanagan River to Osoyoos. The net inflow in
a drought year may only be one-quarter of the average, while in a flood year such
as 1972, it may be double the average.

Past computer models have attempted to simulate the operation of the main-
stem system known as the Okanagan flood-control works (constructed some 15 years
ago). However, these model operations have terminated at the inlet to Osoyoos
Lake because of the hydraulic complexities involved in routing flows through the
lake during flood periods when reverse discharges from the Similkameen River may
occur. However, the 1972 flood on Osoyoos Lake pointed up the need to include
this portion of the basin, and modelling has now been extended to the lake outlet
at Oroville, Wash.
The historic net annual inflow to Okanagan Lake, as well as the results of some
of the key computer results with respect to Okanagan Lake elevations taken from
the Okanagan Study Committee Annual Report for the year ending March 31, 1972,
are shown in Figure 2.
Thus, it will be noted that, assuming the present Okanagan flood-control structures had been in operation for the period 1921 to 1970, Okanagan Lake would
have exceeded its normal high-water elevation by one-half to three-quarters of a
foot in the floods of 1928 and 1948. Similarly, in the drought period of 1929 to
1932, Okanagan Lake would have dropped below its emergency low-water elevation
near the end of 1930, going down an additional 2 feet and not moving above the
emergency low limit until the end of 1932, assuming all downstream requirements
were met.
Okanagan Lake Tributaries
Some of the oldest water licences are in the tributaries of the Okanagan Basin
where upstream storage in combination with diversion dams have provided water by
gravity for irrigation, domestic, and waterworks purposes. The adequacy of this
source of supply to meet the present and growing needs has only recently been
investigated following preliminary studies along the main stem.
Of the many creeks tributary to Okanagan Lake, eight have been selected for
detailed study under Okanagan Basin Study Tasks 35 and 36. These creeks, shown
in the map (Fig. 1), comprise 95 per cent of all headwater storages and contribute
60 per cent of the total inflow to Okanagan Lake. Their watersheds enclose 38,000
acres of irrigated land and include a population of 50,000 (about one-half the total
population within the Okanagan Basin). Hence, these creeks are of prime importance to any hydrologic study of the region.
Work currently in progress on each of the eight tributaries has involved a complex evaluation using computer techniques. Reference to the planning model (Fig.
3 ) provides an outline of the sequence being followed from the initiation of work to
the completion of the report. Because of the shortage of hydrometric record, it was
necessary to develop a theoretical method for deriving natural monthly flows at
selected points within each tributary watershed. This was done by the University of
British Columbia Civil Engineering Department, while its application and use in
the computer model was undertaken by the Water Investigations Branch.
Other important input data to the computer model included delineation of
boundaries, measurement of irrigated areas and population, inventory of storage
and operation, all with projections to the horizon year 2020. Intricate multiple-
storage programmes have been prepared for each of the eight creeks under study
so that the actual operation of the creek under varying flows and water requirements
can be simulated.
Task requirements call for three types of years (dry, average, and wet) to be
studied under present (1970) and future (1980 and 2020) water requirements.
These programmes cover a wide range of possibilities and indicate areas where water
 Y 62
B.C. WATER RESOURCES SERVICE
shortages may be anticipated. The magnitude of flood flows which may be expected
in wet years is also pointed out. The programme is considerably more detailed than
most tributary hydrology studies in that it not only attempts to determine the annual
flow for varying hydrologic conditions but also attempts to break this information
down on a monthly basis at the various diversion points within the basin.
Flooding Around Okanagan and Osoyoos Lakes
In 1972 a heavy residual snow-pack in both the Okanagan and Similkameen
River Basins, coupled with heavy and widely distributed rainfall during a warm
spring, pushed flows to flood levels on tributaries and main channels of the Oka-

nagan and Similkameen Rivers. Okanagan Lake was drawn down to its normal
lower operating limit in anticipation of the large run-off volume. Nevertheless, by
June 30, the lake had risen to elevation 1124.7 (1961 GSC datum), nine-tenths of
a foot above the normal maximum operating level. Flooding was experienced around
Osoyoos Lake, and the lake level reached a record high of 917.02 feet (USCGS
datum) on June 3, 1972, because of the backwater effect of the Similkameen River,
which joins the Okanagan River south of Osoyoos Lake.
As part of its contribution to the Okanagan Basin Study, the Water Investigations Branch examined the 1972 freshet situation at Osoyoos Lake. The claims for
flood reparation submitted by residents were reviewed in conjunction with an on-site
survey of damage carried out by the Okanagan Basin Study. Claimable damage
occurred in various places along the shoreline of the lake, although there were many
areas for which no claims were submitted, either because they were not affected or
because they have been developed by individuals more aware of the potential flooding who built on higher ground. Hardest hit were the delta area at the head of
the lake and the peninsula east of the Southern Trans-Provincial Highway bridge
which has been developed for hotels and motels and camp-sites catering to summer
tourists. Total claims in the area amounted to almost $110,000, of which nearly
$100,000 occurred on the Osoyoos Lake shoreline as a result of high lake levels.
The 1972 flooding of Osoyoos Lake was compared with other record floods
such as that of 1948, and the probability of high lake levels recurring was determined.
Based on the 43 years of continuous data and the known historic maximum level of
918.8 feet on May 29, 1894, floods equal to or exceeding the 1972 level of 917.02
feet may be expected about once in 50 years.
Osoyoos Lake levels are influenced by the water released in the Okanagan
main-stem system from the Penticton Control Dam and the rapidity of snow-melt
in the tributary basins below this point. The Similkameen River, joining the Okanogan just south of Oroville, Wash., at the outlet of Osoyoos Lake, also has significant effect on the lake level for discharges exceeding 17,000 cubic feet per second
at the Nighthawk international gauging station and has, on occasion, caused reverse
flow into Osoyoos Lake. This situation prevailed at the end of May and the beginning of June 1972 when the Similkameen River crested with a discharge of 45,800
cubic feet per second at Nighthawk and again 10 days later when a second peak of
40,000 cubic feet per second was reached. Figure 4 illustrates the correspondence
between Similkameen discharges and high levels on Osoyoos Lake for four of the
highest years on record.
Various flood-prevention measures were examined, including the possibility of
a dam at the outlet of Osoyoos Lake to overcome the influence of high stages on the
Similkameen River downstream. Such a dam, which would have to be combined
with a large-capacity pumping station to handle Okanagan River discharges into
Osoyoos Lake, proved to be prohibitively expensive in comparison with the property
damage that it would prevent during the economic life of the project. The most
realistic long-term solution to the flood problem appears to be flood-plain zoning,
under which any construction on lakeshore land subject to inundation would be
regulated to prevent damage from floods.
Okanagan Main Stem
The water requirements of the Okanagan main-stem lakes and river system
south of the Penticton Control Dam have been under study by the Water Investigations Branch during the year. The effects of alternative water requirements for fisheries use, channel-flushing, and aesthetic purposes, in addition to diversion needed for
3
 Y 66 B.C. WATER RESOURCES SERVICE
off-channel consumptive uses, have been explored in preparation for more detailed
computer analysis both for present-day conditions and for requirements as forecast
for the years 1980 and 2020. These studies are continuing. Estimates of the cost
of modifying irrigation and domestic water-supply intakes along the improved sections of the river channel between Okanagan Falls and Osoyoos Lake were also
made in connection with the analysis of water requirements along the Okanagan
River.
Kalamalka-Wood Lakes Basin Water-resource Management Study
L. A. Bergman, P.Eng., Study Co-ordinator
In the summer of 1971, fairly large surface algae blooms occurred on Wood
Lake. Although algae blooms had been recorded a number of times on this lake
since 1935, local residents and resort-owners associated the 1971 algae bloom with
the cooling water discharge from the Hiram Walker and Sons distillery at Winfield
which had just begun operation. The late and above-average run-off aggravated the
situation by carrying the algas-ladened water of Wood Lake into Kalamalka Lake.
The Okanagan Basin Study Committee, from information at hand, was of the opinion
that the distillery cooling water discharge was not in any way responsible for the
algae-growth conditions which occurred in 1971.
Notwithstanding the fact that the cooling water discharge is of a higher quality
than any water in the Kalamalka-Wood Lakes system, the addition of this discharge
flow may impose a threat to the quality of water in Kalamalka Lake by causing more
of the nutrient-rich water of Wood Lake to flow into Kalamalka Lake. From the
water-quantity point-of-view, the distillery cooling-water discharge is a valuable
asset to the system since the available water in the Kalamalka-Wood Lake Basin is
limited and fully licensed. In any event, removal of the cooling-water discharge
from the system would not solve the basic problem of the Wood Lake algae blooms.
The scarcity of data prohibited any scientific explanation or remedy to the situation.
Subsequently, the Deputy Minister of Water Resources authorized! the Water Investigations Branch to undertake a study which would encompass all aspects of the total
water system such as biology, limnology, hydrology, geology, engineering, and
economics and to concentrate on water inputs and exchanges within the Kalamalka-
Wood Lakes System and nutrient inputs to the system from all sources. The result
of the study should be a better understanding of the water resources of the basin,
which will assist the Comptroller of Water Rights and the Director of Pollution
Control to better and more effectively discharge their responsibilities under the
British Columbia Water Act and Pollution Control Act, 1967.
The objectives of the study are as stated in the Deputy Minister's letter of
August 16, 1971, which are as follows: To obtain information and better understanding of the system necessary for
(1) the regulation of pollution control permits;
(2) the administration of the water licensing system; and
(3) the regulation of water-storage reservoirs such as Kalamalka Lake
and other reservoirs on tributary watersheds upstream from it.
A project proposal was prepared by Water Investigations Branch staff in February 1972 which details some 27 separate studies believed necessary to accomplish
the above objectives, and are summarized as follows:
(1) To determine the present and future water demand of the basin; to
evaluate the availability of water in the basin:

(2) To determine whether additional water could be stored on any of the
lakes in the basin for licensing purposes (use); this will involve
assessment of the hydrology of all major drainages of the basin:
(3) To estimate the cost of rebuilding the outlet works on Kalamalka
Lake to provide a greater degree of lake regulation for flood-control
purposes and possibly water licensing purposes (use):
(4) To determine the present fishery resource in the basin and to estimate its potential:
(5) To assess the nonconsumptive recreational resource (power-boating,
canoeing, swimming, camping, etc.) of Kalamalka and Wood Lakes:
(6) To determine the present quality of the water in the lakes of the
basin; to estimate the influence that man's activities are having on the
quality of the lakes:
(7) To determine the major sources of the present nutrient loading to
the lakes (especially Kalamalka and Wood Lakes):
(8) To make recommendations on means of slowing down or reversing
the eutrophication of Kalamalka and Wood Lakes:
.  (9) To determine whether there should be modifications to the present
method of cooling-water disposal by the Hiram Walker and Sons distillery; to assess the environmental effects of and the costs of various
alternatives.
The services of the Department of Civil Engineering, University of British
Columbia, and British Columbia Research, in addition to Water Investigations
Branch staff, have been utilized in carrying out this water-resource management
study.
Information gathering and data collection began in March 1972, and will continue for one hydrologic cycle. A report on the progress of the study was prepared
by the study participants in August 1972. A public information meeting held in
Vernon in November 1972 on what the study is about and what progress has been
accomplished thus far, was well attended. More information on the study progress
will be found elsewhere in this Annual Report under the various agencies who are
participating in this study (Hydrology Division, Groundwater Division, Ecology
Division, and Water Rights Branch). A final report on the study is anticipated in
December 1973.
WATER SUPPLY AND INVESTIGATIONS DIVISION
R. G. Harris, P.Eng., B.C.L.S., Chief of Division
The functions of the Water Supply and Investigations Division can be divided
into two main divisions—(a) Engineering Investigations Section: To assist and
advise in the development and maintenance of water-supply projects; to carry out
feasibility studies of available water supply; and to carry out miscellaneous hydraulic
investigations, (b) Field Surveys Section: To carry out major surveys required by
the various divisions of the Water Investigations Branch, namely, investigation surveys in connection with feasibility studies on water supply; flood- and erosion-
control and other projects; design and construction surveys; and flood-plain mapping.
In addition, the mapping of major water-storage reservoirs in the Province,
including water-quality sampling, has become one of the functions of this Division.
During the past year, investigations were continued or initiated on six water-
supply projects.    Construction was continued or completed on four water-supply
 Y 68 B.C. WATER RESOURCES SERVICE
projects under the ARDA programme, involving the preparation by the Division of
final design and supervision of construction.
Of the four ARDA projects under construction, three have been completed
and the fourth project is to be completed at the end of 1973.
The main projects dealt with in 1972 are summarized below:
Engineering Investigations Section
WATER-SUPPLY PROJECTS
Proposed Dease Lake Townsite
The proposed Dease Lake Townsite is situated at the south end of Dease Lake
on the Stewart-Cassiar Highway, approximately 60 miles south of the mining community of Cassiar. The townsite area lies on the divide between the Dease Lake and
Tanzilla River Drainage Basins, about 2 miles south of Dease Lake.
The present population is less than 100, including seasonal workers. Present
development includes a Department of Highways' maintenance camp, Forest Service
ranger station, Department of Transport weather station, school, general store, motel,
and cafe, etc. Air transport is provided by two airlines—Transprovincial and Harrison Airways, and helicopter service is provided by Frontier Helicopters.
The Lands Service of the Department of Lands, Forests, and Water Resources
is proposing to extend an existing subdivision into a proposed new townsite. As the
expansion would undoubtedly require water services, the Water Investigations
Branch was requested to carry out a feasibility study for the supply of water to the
proposed community.
Although the basic study would consist of the investigation of an acceptable
water supply and the preliminary design and cost of a water-supply system, town
planning, environmental protection, and recreation would have to be considered in
the study, utilizing the available resources of the various divisions of the Water
Investigations Branch, and other Government departments; in particular, the services
of the Department of Municipal Affairs, who were to be responsible for the planning
of the proposed townsite.
Following a field inspection in the latter part of August, field surveys and a
further engineering inspection were carried out during the latter part of September.
Several alternative sources of supply, including groundwater, were investigated. Surveys included mapping control to extend existing topographic mapping of the area,
and bathometric surveys covering Allan Lake, an unnamed lake to the south of Allan
Lake, and the lower end of Dease Lake.
It is expected that a preliminary report covering this study will be completed
early in 1973.
Peachland Irrigation District
The Peachland Irrigation District is situated within the Okanagan Valley,
approximately 13 miles south of the City of Kelowna, on the west side of Okanagan
Lake. The boundaries of the district enclose a total area of about 1,480 acres, of
which 640 acres are classified as suitable for agriculture.
The original system was installed in 1906 by the Peachland Townsite Company.
However, as the service and the gravity water supply from Peachland Creek proved
to be inadequate, the land-owners purchased the system in 1920 and subsequently
the area was incorporated into the Peachland Irrigation District under the British
Columbia Water Act.
 WATER INVESTIGATIONS BRANCH
Y 69
The district carried out improvements to the system and supplemented the
irrigation supply from Peachland Creek by the development of storage in Peachland
Lake and Wilson Lake Reservoirs. Domestic water was supplied from individual
springs and wells, or from cisterns filled from the irrigation system.
However, in 1965, recognizing that the system had reached the end of its useful
life, and, in addition, it did not meet the present requirements of the district for the
supply of irrigation and domestic water, the Board of Trustees requested that a study
be carried out to consider the feasibility of replacing the existing system with a combined irrigation and domestic water-supply system. Following the completion of a
preliminary report by the Water Investigations Branch in July 1968, financial assistance under the ARDA programme was secured in June 1969, and construction commenced soon after.
Completed in the latter part of 1972, the new water-supply system consists of
a new diversion intake on Peachland Creek, with screening facilities and a headpond
capacity of 16 acre-feet for settling purposes; a distribution system consisting of
60,000 feet of pipe-line of sizes 4 to 24-inch diameter; two booster-pump stations;
seven pressure-reducing stations; and a chlorination station.
With the exception of the screening and spillway structures at the intake, which
were constructed under contract, the major portion of the intake and the distribution
system were constructed by the district's own work force.
Constructed at a cost of approximately $811,000, the new system is presently
serving about 550 acres of agricultural land and 164 domestic users. In addition,
the new system provides emergency water supply to the Municipality of Peachland in
the event of a pumping failure.
Trepanier Area, Municipality oj Peachland
The Trepanier area, which lies mainly within the Municipality of Peachland,
is situated approximately 13 miles south of the City of Kelowna, on the west side of
Okanagan Lake. Basically an agricultural area, it occupies the northern portion of
the municipality.
The existing system, which is administered by the Trepanier Water-users'
Community, consists of ditches, flumes, and low-head pipe-lines, and is no longer
considered to be adequate for present-day irrigation and domestic requirements.
The system is supplied by gravity from Trepanier Creek.
In September 1970 a request was received from the municipality, on behalf of
the water-users within the area, to carry out a study to consider the possibility of installing a combined irrigation and domestic water-supply system.
Preliminary field surveys were carried out in 1970, and the study was initiated
in early 1971.
The area under study consists of about 960 acres of land, of which some 550
acres have been classified as suitable for agriculture. Of the latter areas, about 330
acres are considered eligible for ARDA assistance. In addition, domestic water
could be supplied to about 174 connections.
Present studies indicate that storage supply would be required to supplement
diversion from Trepanier Creek during the low-flow season. Of the three potential
storage-sites investigated, namely, Silver Lake and Lacoma Lake, which lie within
the Trepanier Creek drainage basin, and Cameo (Cameron) Lake, which lies within
the Nicola River Drainage Basin, the latter site appears to be the only acceptable
site for storage development. The development of this site, however, depends upon
the granting of a water licence for diversion and storage by the Water Rights Branch.
 Y 70 B.C. WATER RESOURCES SERVICE
Further field surveys were carried out in 1972 to provide additional field information within the project area, and to assess the storage potential of Cameo Lake.
It is expected that a report on the proposed project will be completed early in
1973.
South East Kelowna Irrigation District
South East Kelowna Irrigation District, incorporated as an improvement district under the Water Act in 1920, contains an area of about 8,627 acres, with over
3,000 acres under irrigation, mainly in tree fruits. The original works were installed
by private companies during the period 1905 to 1911.
Gravity water is supplied to the district by two irrigation systems of about equal
size in area, and one domestic system. The irrigation system to the east is commonly
referred to as the K.L.O. system, with an intake on Canyon (K.L.O.) Creek, while
the irrigation system to the south is known as the S.K.L. system, with an intake on
Hydraulic Creek. The domestic system, with an intake on Canyon Creek and
serving about 200 farm connections, supplies the central area within the K.L.O.
irrigation system.   The remaining areas are served by springs or cisterns.
Commencing in 1964 and continuing through 1968, partial renewals financed
under the ARDA programme have been carried out under three projects, work being mainly done on the S.K.L. system, with lesser expenditures on the K.L.O. and
farm domestic systems.
A fourth project under the ARDA programme was initiated in June 1967,
when the South East Kelowna Irrigation District requested the Water Investigations
Branch to prepare a preliminary report for the proposed rehabilitation of the main
concrete ditch and steel siphon across Canyon Creek and to survey a proposed
storage reservoir for farm domestic supply. This project was expanded in January
1968 when the district requested engineering studies to be carried out on the rehabilitation of the existing Canyon Creek Dams, the development of additional
storage at the Turtle Lake Reservoir site, and reconstruction of No. 9 Dam on
Hydraulic Creek, and further replacements in the diversion and distribution systems.
Subsequently, it was proposed to establish a new intake on Hydraulic Creek
and to construct a fully pressurized combined irrigation and domestic system. Following the completion of field surveys in 1969, a preliminary report, "Proposed Rehabilitation of the South East Kelowna Irrigation System—Fourth ARDA Project
Proposal," was completed in January 1970. The proposed project, with an estimated capital cost of $3,600,000, was approved for ARDA assistance in June 1970.
The new system will provide irrigation water to approximately 4,335 acres of
farm lands and domestic water for approximately 660 connections.
Rehabilitation of the distribution system, construction of a 4 Vi -mile-long diversion ditch from Pooley Creek and improvement of the existing Myra Ditch to supplement the inflow into McCulloch Reservoir, and the construction of a new all-year
round diversion intake on Hydraulic Creek, is being carried out under the supervision of the ARDA Division.
Rehabilitation of storage works on the McCulloch Reservoir is being carried
out under the supervision of the Water Supply and Investigations Division. To provide the district's annual water requirement of about 12,700 acre-feet, the McCulloch
Reservoir has been reconstructed to provide additional storage.
With a design capacity of over 12,000 acre-feet, the McCulloch Reservoir is
now the largest-capacity reservoir in the Okanagan Valley.
During 1970, construction consisted of the initial enlargement of the Myra
Ditch to accommodate the flow from the proposed Pooley Creek diversion, the construction of a new access road connecting McCulloch Reservoir and the Pooley
 WATER INVESTIGATIONS BRANCH
Y 71
Creek-Myra Ditch diversion system, the improvement of 14 miles of existing access
roads, and clearing of the present flooded area of McCulloch Reservoir.
During 1971, approximately one-third of the proposed rehabilitation of the
district's storage works was completed. Briefly, the 1971 construction programme
consisted of both work under contract and by district forces. Under contract, the
main components of McCulloch Reservoir are being rehabilitated, namely, the reconstruction of four dams, the construction of a new spillway, and the enlargement
of an existing ditch connecting Haynes, Minnow, and Hydraulic Lakes. These lakes
form the major portion of McCulloch Reservoir. Approximately 25 per cent of this
work was completed during 1971. Work carried out by district forces during this
period consisted of clearing, burning, and stripping the Pooley Creek diversion ditch
right-of-way, diverting Stirling Creek into Pooley Creek-Myra Ditch system, and
clearing the new flooded area of McCulloch Reservoir.
During 1972, rehabilitation of the McCulloch Reservoir storage works was
completed, with the exception of the intake works at the North Dam and the measuring weir.
It is anticipated that the rehabilitation of the storage works will be completed
by the end of 1973.
Westbank Irrigation District
Westbank Irrigation District, which includes the Townsite of Westbank, is
situated approximately 7 miles south of the City of Kelowna, on the west side of
Okanagan Lake.
During the period 1958 to 1963, the district carried out partial rehabilitation
of the existing distribution system by financing renewals from the Renewal Reserve
Fund. However, in 1964, faced with immediate and costly replacement of the remaining portions of the distribution system, including major improvements to the
storage works, the district applied for ARDA assistance.
The construction of a concrete intake dam and screening works, and the installation of 7,000 feet of 34-inch-diameter steel pipe-line, represented the first phase
of rehabilitation of the district's works under the ARDA programme. This project
was completed in April 1966 at a capital cost of $160,000.
The second phase of rehabilitation includes the replacement of the district's
distribution system to provide approximately 1,500 acres of irrigable land with a
combined irrigation and farm domestic supply. The 1,500 acres of irrigable land
are composed of approximately 1,000 acres within the original Westbank Irrigation
District and 500 acres within the Powers Creek Water-users' Community, which has
now been incorporated into the Westbank Irrigation District.
Formerly, the settlement of Westbank and a number of farms within the irrigation district were being provided with domestic service from a system installed by
the Westbank Waterworks District and supplied from the Westbank Springs. With
the amalgamation of the waterworks and irrigation districts, this area is now being
served from the new system.
The new distribution system, which was completed during the latter part of
1972, includes approximately 75,000 feet of pipe-line of sizes 4 to 24-inch diameter,
seven pressure-reducing water stations, and a combined booster pump and chlorina-
tion station.   A new office building has also been constructed.
Originally it was proposed to rehabilitate the district's six existing storage reservoirs to provide the required storage supply. However, based on more recent
hydrologic information, it was possible to develop the required storage in Lambly
(Bear) and Jackpine Lakes, two of the district's existing reservoirs.
 Y 72 B.C. WATER RESOURCES SERVICE
Approximately 2,560 acre-feet of storage have been developed on Lambly
Lake, an increase of over 1,900 acre-feet. Reconstruction of the storage works
included the replacement of the North Dam, approximately 1,400 feet in length,
raising of the South Dam and reconstruction of the outlet works, construction of a
new spillway, and the diversion of Paddle Creek into Lambly Lake to augment the
reservoir inflow. The storage works on Jackpine Lake were replaced to maintain the
existing storage of about 1,000 acre-feet. Combined impact basins and measuring
weirs were installed at the outlets of both Lambly and Jackpine Reservoirs. The
storage works were completed in the fall of 1972.
The total cost of the project is about $1,407,000.
Glenrosa Area, Westbank Irrigation District
The Glenrosa area is situated to the south of Powers Creek, adjacent to the
west boundary of the Westbank Irrigation District. Basically an agricultural area,
the land is presently being dry-farmed for use as pasture or the growing of hay crops.
In 1969 the land-owners within the study area submitted a petition to the
Westbank Irrigation District requesting that the new ARDA system be extended to
provide the area with both irrigation and domestic services.
Office studies and field surveys were initiated in the latter part of 1971, during
final stage of construction of the present ARDA project.
The area under study consists of about 180 acres classified as suitable for agriculture.   In addition, domestic water could be supplied to about 33 connections.
Present studies indicate that storage supply would be required to supplement
the diversion from Powers Creek, in addition to storage supply already developed in
Lambly (Bear) Lake and Jackpine Lake Reservoirs under the present ARDA project. The development of the required storage supply in Paynter Lake, one of the
district's remaining reservoirs, is being considered.
It is expected that a report on the proposed Glenrosa area extension will be
completed early in 1973.
Potential Storage-sites, Similkameen Basin
During the latter part of 1972, studies were initiated for the investigation of the
most favourable potential storage-sites within the Similkameen Basin. Recommendations, which will include preliminary cost estimates, to a considerable extent
will be dependent on the tributary yield studies to be carried out by the Hydrology
Division.
In general, the studies will be based on an assessment of the tributary water
requirements within the basin presently being carried out by the Water Rights
Branch.
Field surveys initiated in 1964, under the Similkameen Basin Storage Inventory
Programme, are to be extended, and will include topographic and bathometric reservoir-site mapping, water-quality sampling, dam-site investigation, inventory of lake-
front land use, etc.
At the present time, area-elevation curves are being prepared for the water-yield
studies. In addition, reservoir mapping is being prepared from field surveys carried
out during the period 1964-72 under the inventory programme.
Additional field information will be obtained during the 1973 field season, to
allow completion of the study.

FLOODING, DRAINAGE, AND EROSION PROJECTS
Pemberton Valley Dyking District
Under the tripartite agreement among the Pemberton Valley Dyking District,
the Federal Government, the Provincial Government, and the Prairie Farm Rehabilitation Administration (PFRA), Canada Department of Agriculture, carried out
certain dyking and drainage works in the Pemberton Valley from 1946 to 1953.
As a result of these works, some 12,000 acres of fertile land were reclaimed or
protected from flooding. Area 2, however, in which the Village of Pemberton is
situated, and which extends from Green River to Miller Creek, still has flooding
problems during the high water. As a result, a request was received from the district
for assistance under the ARDA programme to further improve the area. These
improvements would allow reclamation of farm lands and increased agricultural
production, involving about 2,000 acres.
Following the completion of field surveys in 1965 and 1966, a preliminary
report was completed in 1967. Two alternative schemes were investigated—(a)
drainage by gravity, by diverting One Mile Creek into the Green River; and (b)
drainage by pumping at the confluence of the canal draining Area 2 and One Mile
Creek.
The pumping scheme, with an estimated capital cost of $103,000 and annual
cost of $5,604, was recommended because it would provide better protection against
flooding.
Following completion of the report, further reports of flooding and erosion were
received and, at the request of the district, the area of investigation was expanded
to include the section of Pemberton Valley extending from Tenasse Lake, downstream of Lillooet Lake, to about 22 miles upstream of Lillooet Lake. Additional
surveys were carried out to further the investigation, including detailed office studies.
A topographic map, based on 1971 air photography, was prepared in 1972 to complement the report.
The feasibility of lowering the outlet of Lillooet Lake to improve flooding conditions upstream of the lake was considered. This proposal was found to be too costly
and to have limited benefits.
Two flood-control schemes were developed—Scheme 1, which includes the
Indian reserve lands that lie within the boundaries of the Pemberton Valley Dyking
District, suggests that additional dyking, bank-erosion control, improved drainage,
and confinement of the Lillooet River to its main channel are required. Scheme 2,
which excludes the Indian reserve lands, suggests similar improvements.
Scheme 1, which would affect about 11,620 acres of land, was estimated to
cost $2,523,000, while Scheme 2, which would affect about 9,320 acres of land,
would cost $1,874,000.
Lillooet River Delta Study
Large loads of sediment being carried annually by the Lillooet River are being
deposited at its delta on Lillooet Lake.
In order to study the processes of sediment distribution and the volume of sediment being deposited, a survey programme has been initiated.
The delta has been controlled for above-surface detailed photogrammetric
mapping, and reference lines established for subaqueous mapping by sounding.
The frequency of mapping will be based on the degree of sediment deposit.
 Y 74 B.C. WATER RESOURCES SERVICE
Lake Windermere
Following representations made by a number of residents living along the shoreline of Lake Windermere, situated in the East Kootenay region of the Province, an
investigation was initiated in late 1969 to consider the feasibility and cost of constructing a control dam at the outlet of the lake for the purpose of regulating the
water level during the latter part of the summer to facilitate the launching of boats.
As a flooding problem exists during the early part of the summer, this problem is
also under investigation.
Lake Windermere, which has a maximum depth of water of just over 20 feet
and contains numerous shallow bays, has an extensive growth of aquatic weeds
which also presents a problem to boating.
As the adjoining marsh lands are watering areas for wild fowl, the effect from
altering the natural water level of the lake would also have to be considered.
For the purpose of considering the feasibility of regulating the lake level for
boating, a bathometric survey was carried out covering the developed areas at the
northern end of Lake Windermere, including the communities of Athalmer and
Invermere. The position and elevations of the major boathouses were also established.
In order to study the effect of flooding on low-lying lands, in particular the
community of Athalmer, the area extending from Lake Windermere to Toby Creek,
a tributary of the Columbia River, downstream of Lake Windermere, has been
mapped. In addition, in order to study any possible backwater effect on Lake Windermere from Toby Creek during spring run-off, a number of gauging stations were
established on the Columbia River and Toby Creek. These gauges were read during
the 1970 spring run-off period. However, as 1970 was a below-average run-off
year, it was considered advisable to record the record high flows during the spring
of 1972 to determine the maximum effect from backwater.
Initial studies considered the feasibility of developing upstream storage on
Dutch Creek, the only major stream entering into Lake Windermere, to control
spring flooding and to regulate summer lake levels. However, owing to the estimated
high cost of development, this scheme did not appear acceptable.
Further proposals are now being considered, namely, the diversion of Toby
Creek to relieve the flooding from backwater effect and the construction of alternative
control works at the outlet of Lake Windermere to regulate the summer lake levels.
Salmon Arm Wharf Channel, Shuswap Lake
In September 1971, field surveys were carried out for the purpose of investigating the silting problem in the channel leading to the Salmon Arm wharf on Shuswap
Lake, immediately south of the outlet of Salmon River, as a result of a request
received from the local Salmon River Study Committee. These surveys involved
extensive sounding of Shuswap Lake in the vicinity of Salmon Arm and the outlet
of Salmon River, river-channel sections, and ground-control for mapping of the
area between Shuswap Lake and the main highway.
During the course of this study, which has now been completed, a pilot channel
excavated in 1969 has been developed by river action until it is now taking the main
flow of the Salmon River. This action has directed the main flow of the river away
from the wharf channel, generally eliminating the deposit of river silt in the channel.
It was recommended that, to stabilize the new route of the Salmon River, a
river-training wall be constructed across the old channel.
The cost of carrying out this work has been estimated at $2,000.

Field Surveys Section
During the summer season the field surveys staff attached to the Division
carried out a number of field surveys required by the several divisions of the Water
Investigations Branch in connection with water supply, erosion, flood control, and
drainage studies. A total of over 25 major surveys and several miscellaneous surveys were carried out during the field season.
The two field parties, composing the field survey staff, normally operate with
a staff of five each during the winter period, increasing to eight each with the hiring
of summer students during the field season.
Although the main compilation of the field data is carried out by the field staff
during the winter period, the final compilation, the filing and indexing of survey data
and maintenance of survey equipment, is the responsibility of the compilation
section.
Some of the major surveys which were carried out in 1972 are summarized
below.
Water-supply Projects
Kalamalka-Wood Lakes Basin Study
In connection with a water-resource management study being carried out on
the Kalamalka-Wood Basin with the Okanagan Basin, the following field information was requested:
(1) Navigational markers to be established on Kalamalka and Wood
Lakes; preparation of area-elevation curves covering major lakes in
the basin; and sounding of Ellison Lake for ecology study:
(2) Preparation of "as-constructed" drawings of Kalamalka Lake outlet
works, including detailed site topography; cross-sections and thalweg
profile of Vernon Creek from Kalamalka Lake to Okanagan Lake;
cross-sections and thalweg profile of channel between Wood and
Kalamalka Lakes; location of improvements on Wood and Kalamalka Lakes, related to water level that might be affected by any
proposed change in lake level; shoreline topography 5 feet above and
below existing water level, involving sounding; cross-sectioning and
detailing topography:
(3) Establishing elevations of existing wells and test wells in the basin
being used in connection with a groundwater study:
(4) Metering of a number of streams in connection with a hydrology
study:
(5) Locating and establishing elevations of a number of test-pits.
The above field work has been completed and the processing of data will be
completed early in 1973.
Peachland Irrigation District
Following completion of the district's new intake on Peachland Creek in 1970
under the ARDA programme, approximately 3,000 cubic yards of slide material
were deposited in the headpond during the 1971 run-off period, with a further
10,000 cubic yards being deposited during the 1972 run-off period.
In order to estimate the cost of removing the gravel deposit from the pond in
1971 and 1972, both topographic and bathometric surveys were carried out.
 Y 76 B.C. WATER RESOURCES SERVICE
South East Kelowna Irrigation District
In connection with the construction of the Pooley Creek-Myra Ditch diversion system under the ARDA programme, the route was re-cross-sectioned following
clearing and stripping in 1970.
Following design of the channel section, grade stakes were set and referenced
for replacement.
In addition, following completion of the reconstruction of the McCulloch
Reservoir storage works, an "as-constructed" survey was carried out.
Trepanier Area, Municipality oj Peachland
In connection with a feasibility study being carried out by this Division on the
proposed Trepanier area water-supply system, Cameo (Cameron) and Silver Lakes,
lying within Nicola River and Trepanier Creek Drainage Basins respectively were
sounded, and detailed damsite topography obtained for the purpose of assessing
the availability of storage supply. In addition, the reservoir area and the proposed
diversion route from Trepanier Creek were controlled for photogrammetric mapping.
Water-storage Reservoir Inventory
A programme of mapping major water-storage reservoirs in the southern
Interior of the Province of British Columbia was initiated by this Division in 1964.
The principal areas included under this programme are the Okanagan and Similkameen Basins. The surveys have included both existing storage reservoirs and
potential reservoir-sites, and the information has been used in the investigations of
water supply in the water-deficient areas, and has assisted in the administration of
water r'ghts. This information has also been the basis of design in the reconstruction of a number of existing storage dams under the ARDA programme.
Reservoir maps are being prepared by photogrammetry for above-surface
mapping, and the use of echo-sounding equipment for subaqueous mapping. Detailed damsite mapping and plans of existing storage works are prepared from
field survey data.
Of the approximately 160 storage reservoirs at present under licence in the
Okanagan Basin, about 115 reservoirs are in operation. The capacity of these
reservoirs varies from a minimum of about 1 acre-foot to a maximum of about
12,000 acre-feet, which has been developed in McCulloch Reservoir under the
South East Kelowna Irrigation District ARDA project.
A large percentage of the reservoirs in operation with a capacity of 100 acre-
feet or more have been surveyed, with an additional 12 lakes being surveyed in
1972. Drawings are under preparation for approximately 35 lakes, including about
28 lakes surveyed during the 1971/72 field seasons. It is estimated that an additional 30 reservoirs in operation over 100 acre-feet capacity, plus about 10 reservoirs
licensed for development, will require surveys and mapping. Reservoirs with a
capacity of less than 100 acre-feet capacity have not been included in the present
programme.
Of the 29 storage reservoirs licensed in the Similkameen Basin, approximately
10 reservoirs plus five potential sites have been listed for survey. It is anticipated
that the survey programme in the Similkameen Basin will be completed during the
1973 field season.
In connection with the proposed development of the new townsite of Dease
Lake in the northern Interior of the Province, bathometric surveys were carried out
on three lakes for recreational and water-supply purposes.

In connection with the proposed improvements to be carried out to the Fraser
River dyking system under the Canada-British Columbia Fraser River Flood Control Agreement, detailed soundings were taken of a 1-mile section of the Fraser
River downstream of the new Mission Bridge.
In addition, peak velocities were measured during the spring run-off over the
section of river extending upstream from tidewater, a distance of about 80 miles.
Pemberton Valley Dyking District
In connection with flooding problems from the Lillooet River and its tributaries
in the vicinity of the community of Pemberton, a mapping programme, including
detailed surveys, was carried out in 1965 and 1966 by this Division, followed by the
preparation of a report in 1967 entitled "Preliminary Report on Pemberton Valley
Dyking District Drainage Proposals."
In 1968, the area of investigation was expanded to include the section of Pemberton Valley extending from the outlet of Lillooet Lake to a point about 16 miles
upstream from Pemberton, a distance of approximately 36 miles.
In 1969, to carry out a more detailed analysis of the flooding on the Lillooet
River system, including Lillooet Lake, additional hydrometric data were obtained,
extending from below Tenasse Lake to about 22 miles upstream of Lillooet Lake.
In 1970, additional mapping control, topography, and other appurtenant information were obtained to allow completion of the new study. The study was further
expanded in 1972 to include Ryan Creek, a major tributary of the Lillooet River,
and additional mapping and hydrometric data were obtained.
Similkameen River
In response to requests for flood and erosion control on the river, a field survey
was carried out during the summer of 1969. Cross-sections and channel profiles
were taken over a 60-mile section of the river, extending from Princeton to the
International Border. In addition, the Similkameen Valley covering this section
was controlled for mapping.
Following a record run-off during 1972, the above section was again cross-
sectioned and profiled to assess the flood damage and to provide engineering data for
channel improvements.

Snow-course Network
During the 1972 snow-sampling season, snow surveyors made 1,041 visits to
British Columbia mountain snow courses to obtain data for use in assessing the
build-up and depletion of the extremely heavy 1972 snow-pack. Of this total, 270
visits were made by aircraft and 771 by ground access. The Hydrology Division,
through personnel and co-operating agencies and part-time employees, measured
snow depth and water equivalent of 210 active courses near eight key sampling-
dates. Most courses were measured near March 1, April 1, and May 1 when long-
range quantitative run-off volume forecasts for the coming spring and summer snow-
melt season are made. Key courses were measured near January 1 and February 1
to provide early warning of the degree of snow-pack accumulation, and near May
15, June 1, and June 15 to monitor snow-pack depletion during the melt period.
In 1972, six new courses were added and five deleted. Of the deletions, two
were discontinued because of avalanche hazard created by a forest fire and three
due to lack of local observers. Additions include two reactivations, three as backup
to existing courses which are expected to terminate soon, and one new course in an
area where representative data were lacking. Details applicable to each are listed in
the following table. A total of 219 courses will be operational in 1973.

Hydrology Division technicians visited 103 snow courses during the winter
months to provide local snow surveyors with instruction in measurement technique,
in care and maintenance of sampling equipment, and in the recording and transmission of the data to Victoria. In addition, they serviced the Division's six snow-
pressure pillows and associated hydrometeorological instrumentation located near
the Barkerville, Mission Creek, Blackwall Peak, Mission Ridge, McBride, and Moyie
Mountain snow-course sites. During the summer, 67 courses were brushed and
cleaned up in preparation for the coming sampling season. This winter instruction
and summer maintenance work totalled 200 man-days and resulted in 26,500 miles
of travel by vehicle, 3,950 by helicopter, and 615 by power toboggan.
 WATER INVESTIGATIONS BRANCH
Y 79
During 1972, map reserves were established for 21 snow courses and five
pressure-pillow sites. Reserve applications submitted but still pending include seven
snow courses and one pillow-site.
Streamflow Forecasting
Quantitative volume forecasts covering the spring and summer period, based on
procedures developed by computer from snow-pack, hydrometric, and meteorological measurements, were made for British Columbia rivers as well as for inflow to
major lakes and reservoirs. These were first made March 1 and updated April 1
and May 1. Forecasts, together with snow-pack, hydrometric and meteorological
measurements, reservoir storages, and other applicable information, were presented
in graphical and written form in the seven issues of the British Columbia Snow Survey
Bulletin. These bulletins were mailed immediately following the February 1,
March 1, April 1, May 1, May 15, June 1, and June 15 sampling dates to over 800
subscribers, all with a direct interest in British Columbia run-off conditions.
Above to well-above-average mountain snow-packs and the possibility of a
high run-off potential were recognized early and reported in the February 1 Snow
Survey Bulletin. The following issues of March 1, April 1, and May 1 continued to
provide warnings as heavy precipitation, combined with below-normal temperatures
to produce record or near record high accumulated snow-packs on watersheds in
the southern half of the Province. As a result of this heavy accumulation of snow,
published volume forecasts were near record or record high for the forecast periods
April through July and April through September. Also, early warning of potential
flooding was given in the bulletins for the Okanagan, Similkameen, Kettle, Thompson, Fraser, Upper Kootenay, and Upper Columbia regions. Preliminary stream-
flow data, as supplied by the Water Survey of Canada, show that observed flows
were either in close agreement or greater than those forecast. The forecasts gave an
excellent indication of the flows to come, with this especially true of the flood potential. The following table provides a comparison between forecast and actual as
well as previous maximum recorded volume run-off for a few selected regional
stations:

During the freshet period, daily plots of discharge and stage were maintained
for those rivers subject to flooding. Through the co-operation of the Water Survey
of Canada and the Atmospheric Environment Service, daily reports were received
from 44 hydrometric stations and 14 key weather stations and plotted graphically
to provide a comparison with previous years and to illustrate the time-lag relationship
 Y 80
B.C. WATER RESOURCES SERVICE
between both temperature and precipitation, with stream-flow. In addition, a daily
plot was maintained throughout the year of both Okanagan Lake level and Okanagan
Lake discharge and during the period April-June a daily plot was made to Osoyoos
Lake level, Okanagan River flow at Oliver, selected tributary flow, and pertinent
meteorological data. All plots were used in making Okanagan Lake release flow
decisions.
Cool temperatures predominated throughout April and the first three weeks of
May, delaying snow-melt run-off. However, in the last week of May, warm air
blanketed the Province, causing a rapid melt of the extremely heavy snow cover on
Interior watersheds. During this warm spell, southern Interior rivers such as the
Similkameen, Okanagan, Kettle, and North and South Thompson rose to flows either
just below or just above those recorded in the 1948 flood-year, with flooding conditions reported in the Similkameen and southern Okanagan regions. Fortunately,
cooler Pacific air entered the Province June 1 and provided a braking action and
downward trend to Interior river stages. This was followed by heavy and widely
distributed rainfall during the period June 10 to 12, which once again pushed river
levels to flood stages, with these stages especially critical in the Kamloops area.
Fraser River peaks would have been much higher but for the storage of water in
the Nechako Reservoir prior to and during the crucial high-water period. It should
also be pointed out that the operation of Columbia River Treaty Dams prevented
flooding in the lower Kootenay and lower Columbia regions. The following table
provides a comparison of preliminary 1972 mean daily peak-flow discharges and the
previously recorded maximums for selected stream-gauging stations.

Hydrology Studies
Engineers attached to the Division carry out special studies related to water
supply and other flow-regime problems. The following hydrological studies describe
those completed or in progress during 1972:
1. Under the Canada-British Columbia Okanagan Basin Agreement, Division
personnel completed the following:
1.1 Regionalization oj sub-basin hydrology—The final report on "Application of the Grid-square Method for Estimating Okanagan Sub-basin Run-off"
was completed. It covers all aspects of the preliminary report and represents
a mean monthly run-off model which was incorporated into the grid-square
 WATER INVESTIGATIONS BRANCH
Y 81
method. Results based on the method's first estimates are given for mean
monthly and annual temperature, precipitation, evapotranspiration, and runoff for each of the 500 5-km. squares covering the Okanagan Basin.
1.2 Sub-basin analyses—A final report is 90 per cent complete on estimating sub-basin run-off characteristics using physiographic characteristics as
run-off predictor indices. Stream-flow data collected in 1971 and 1972 on
22 gauged sub-basins are correlated, using multiple regression analysis, with
selected physiographic characteristics. The relationships obtained from the
gauged sub-basins can then be extrapolated to estimate run-off characteristics
on ungauged Okanagan sub-basins.
1.3 Okanagan jreshet-flow metering programme—In order to provide
additional natural stream-flow data for studying the variation of run-off with
elevation in the Okanagan Basin, weekly discharge measurements were obtained
at 12 locations in the Okanagan Basin. The streams were selected on the basis
of elevation, access, and proximity to gauged sub-basins and were metered by
the Water Survey of Canada from April 21 to September 22. A daily hydro-
graph was obtained from these weekly measurements by relating the run-off
pattern to a nearby continuous recording gauging station. Thus, for 1972,
April-September natural run-off data are available for 34 rather than the
previously stipulated 22 gauged sub-basins. The additional data will be used
to develop a more accurate assessment of regional run-off variations in the
Okanagan Basin.
1.4 The Chief of the Division presented a report on Okanagan Lake operation at a Public Participation Seminar in Naramata.
2. Kalamalka-Wood Lake Basin Water Resource Management Study—The
Hydrology Division is responsible for the hydrology portion of this study which
began in late 1971. To date, three final reports have been prepared. These describe
the "Hydrometric Gauging for 1972," the "Run-off Conditions of 1969, 1970, and
1971," and the "Annual Run-off Relationship," which incorporates an elevation
run-off relationship for estimating mean, maximum, and minimum run-off for ungauged portions of the Kalamalka-Wood Lake watershed. Data for 1972 are currently being analysed and distributed to other groups involved in the study. In
addition, a report on water availability and water use was presented at a Public
Involvement Meeting in Vernon by a member of the Division.
3. Okanagan Lake Operation, 1972—This report was completed. Its purpose
was to evaluate the operation of Okanagan Lake during the critical May-June flood
period and to show the effect of this operation on both Okanagan and Osoyoos Lake
levels.
4. Reverse Flows Into Osoyoos Lake—This study was continued. A lake level
versus outflow relationship with no backwater effect was determined. The previous
relationship between Osoyoos Lake level, Similkameen River flow, and the reverse
flow was expanded to cover the full range of conditions for Osoyoos Lake. This
relationship was used prior to and during the 1972 flooding on Osoyoos Lake to
minimize over-all flood damage.
5. Mission Creek hydrology study—A final report was completed on run-off
estimates and storage calculations for the Black Mountain Irrigation District water
supply.
6. Trout Creek hydrology study—A final report was completed on run-off
estimates and storage calculations for the Summerland Irrigation District water
supply.
 Y 82 B.C. WATER RESOURCES SERVICE
7. Hydrology studies to determine water supply were commenced in 1972
for Glenmore-Ellison Irrigation District (Kelowna Creek) and Trepanier Water-
users' Community (Trepanier Creek).
8. A study was completed to estimate the annual low flow for Moody Creek
near Christina for design of a water-supply system for Christina.
9. Frequency analyses for selected return period peak daily lake levels were
completed for Williams Lake and Lac la Hache and peak daily discharges for Trout
Creek.
10. Investigation and hydrologic analysis of the Similkameen River Basin was
started in late 1972.
11. International Hydrological Decade projects:
11.1 Since the final report on the Okanagan Study Basin (Near Cans
Landing) was published in June 1971, selected precipitation, temperature, and
groundwater measurements continue to be collected. A listing of 1971 and
1972 data is being prepared.
11.2 The basic data-collecting phase of the International Hydrological
Decade "Mountain Transect" project on the Beaufort Range, Vancouver Island,
was discontinued in September 1972. Prior to removing the instruments from
the 10 meteorological stations, nine helicopter trips were made during 1972,
five by Hydrology Division technicians and four by our co-operators, the
Atmospheric Environment Service. The project's objective is the development
of objective estimating techniques for precipitation and temperature distributions in mountainous terrain. A draft of a preliminary report has been completed, and Atmospheric Environment Service officials advise that current work
involves the analyses of the basic data collected.
Computer Programmes
1. During 1972 the Okanagan grid-square study computer programming was
completed. This included the grid-square iterative regression programme, development of a X-Y printer plot routine, a geographical data plotting routine, and various
other programmes to analyse data, produce report listings, data summaries, and to
store data on either punched cards or on magnetic tape or both.
2. Five programmes were developed to process the Okanagan meteorological
data, received on magnetic tape or punched cards from the Atmospheric Environment Service, in order to make the data more easily accessible to others for computer
processing and to produce listings of the data for use in the Hydrology Division
library. These data are currently updated to the end of 1971.
3. British Columbia stream-flow data, updated to the end of 1970, were
received from the Water Survey of Canada on magnetic tape and are available as
such and also on listings now retained in the Hydrology Division library.
4. Two new snow-survey programmes were produced in order to create more
comprehensive snow-course summaries than were previously available and to increase the efficiency and decrease the possibility of errors in the production of the
Snow Survey Bulletins.
5. A computer programme was written for calculating storage conditions in
studies of water supply. Using run-off data obtained in hydrology studies plus
demand and revervoir capacities, this programme produces estimates of total month-
end storage in place under various operation conditions. Any number of years can
be studied in sequence and parameters such as run-off, demand, and revervoir
 WATER INVESTIGATIONS BRANCH
Y 83
capacities can be varied to determine the amount of storage required to satisfy
demand.
6. Three programmes were developed for the Groundwater Division for use
on a minicomputer to assist in the processing and analysis of the chemical composition of groundwater.
7. A programme for the Okanagan Basin water-quantity study was modified to
sum flows in a drainage basin network of any complexity.
Miscellaneous
As a continuing function, the Division's hydrometric and meteorological data
libraries were updated in 1972 and the data used by Water Resources Service personnel in their studies. As co-ordinator for requests for unpublished hydrometeoro-
logical data, many requests were made to the Water Survey of Canada and the
Atmospheric Environment Service for such information.
Another continuing annual function is the co-ordination of Departmental
stream-gauge installations under a Federal-Provincial agreement. In 1972, a listing
comprising 22 all-year, 80 irrigation period, 31 pollution control, and 21 regional
hydrological stations was compiled and forwarded to the Water Survey of Canada,
the Federal agency responsible for stream-gauging installations.
As in previous years, personnel of the Division continue to be active as members
of interdepartmental, Provincial, national, and international working committees
which deal with problems applicable to hydrology. These include Resource Data
Subcommittee (ELUTS), Earth Resources Technology Satellite Committee (ERTS),
British Columbia Co-ordinating Climatological Committee, British Columbia Hydro-
meteorological Networks Co-ordinating Committee, National Research Council Hydrology Subcommittee, Columbia Basin Forecast Committee, Western Snow Conference Executive Committee.
As General Chairman of the Western Snow Conference for the second year of
a two-year tenure, the Chief of the Division was responsible for the many details
associated with its administration, including the handling of the annual meeting which
was held in Phoenix, Ariz., in 1972.
As a member of the Technical Programme and Tours Committees for the
"International Symposia on the Role of Snow and Ice in Hydrology," held September
1972 in Banff, the Chief of the Division, together with staff members, was involved
in the planning and implementation of this highly successful conference.

Collection and Compilation of Basic Data
During 1972, initial steps were taken to improve storage and retrieval of the
rapidly accumulating volume of basic data within the Division. The initial phase
has comprised introduction of a standard, geographically oriented cross-indexing
facility based on the National Topographic Series map-numbering system (N.T.S.).
The geographic orientation of data is designed to permit more ready compilation
and interpretation. To date, the existing technical data in Division reports and files
has been cross-indexed in this manner. Proposals are currently being formulated for
the next phase of this work, which involves processing water-well and chemistry data.
 Y 84 B.C. WATER RESOURCES SERVICE
The three major classifications of data assembled and compiled by the Division
are water-well data, observation well data, and groundwater chemistry data; their
status at year-end is summarized as follows:
Water-well Data
Information continued to be assembled through the co-operation of water-well
drillers, other Government agencies, and consulting groundwater geologists. A total
of 1,562 new water-well records was obtained; this represents a decrease of 438
well records over the previous year's total of 2,000. There are currently 5,000 outstanding well records which require locations.
Detailed inventories were carried out for special projects in the Saanich Peninsula, the Gulf Islands, and the Terrace area. Approximately 215 new or corrected
records resulted from these inventories.
Water-well Maps
A total of 75 new water-well maps was compiled during the year. These new
maps cover areas in the following districts:
District Number of New Maps
Cassiar  13
Cariboo  3 0
Range 5, Coast  21
Lillooet   10
Queen Charlotte Islands     1
Total  75
Special Project Maps
A total of 72 hydrogeological, hydrochemical, and other maps and work sheets
and nine aerial photograph mosaics was prepared for special projects such as the
Gulf Island Study, Thornhill planning area near Terrace, and the Dease Lake proposed townsite.
Observation-well Data
At year-end 1972 the Division was monitoring 178 observation wells throughout the Province. Eighty-two of these comprise a network of continuing observations
and 96 are being observed for shorter term special-project purposes. Automatic
water-level recorders have been installed in 12 of the continuing network wells and
in 26 of the special project wells. During 1972 the wells in the continuing network
were inspected in March and November for servicing and collection of key water-
chemistry parameters.
An appraisal of the hydrographs obtained to date from wells in the continuing
network was carried out during 1972 with the aims of assessing the quality of data
and establishing criteria for orienting the network toward improved hydrogeological
value.
This appraisal indicates that a number of wells should be phased out of the
continuing network in the next water year. Two new wells were added to the network in 1972—one in north Saanich and one in Vanderhoof.
 WATER INVESTIGATIONS BRANCH
Y 85
At year-end 1972 the distribution by watershed of observation wells in the
continuing network was as follows:
Coastal watersheds  6
Fraser watershed and Lower Mainland  38
Okanagan and Similkameen watersheds  29
Columbia watershed  2
Northern watershed  7
Total
82
The number of wells being monitored for special-project purposes during 1972
was influenced mainly by the addition of 43 new wells introduced for the Kalamalka-
Wood Lake Basin Water Resource Management Study, for the Gulf Islands Study,
and the deletion of 63 wells previously monitored by the Division for the Kootenay
Flats special project study.
The distribution of special-project observation wells at year-end was as follows:
Kalamalka-Wood Lake   43
Okanagan Valley "study areas"  33
Okanagan Basin Study     9
Athalmer     5
Gulf Islands     6
Total
96
Groundwater Chemistry Data
A total of 505 water samples collected from springs, creeks, and wells was
analysed for major ions by Groundwater Division personnel, using the Hach Water
Engineers' laboratory kit. Additional samples were sent to the Water Resources
Laboratory in Vancouver for analyses.
The distribution of the samples was as follows:
Saanich   46
Gulf Islands   278
Selected map sheets   181
The data are in the process of being tabulated and compiled on maps and
graphs for special projects.
Special Projects
Federal-Provincial Okanagan Basin Study Groundwater Programme
The groundwater programme forms part of the water-quantity studies being
undertaken by the Water Investigations Branch.
During the past year, two groundwater reports have been prepared under this
programme by Groundwater Division personnel and have been edited by a joint
Federal-Provincial Groundwater Advisory Committee. The reports constitute
completion and near-completion of work under Tasks 41 and 47 respectively. Task
41 report covers cleaning, development, test-pumping, and construction of test-holes
drilled under Task 40 and completed for observation-well purposes.

Task 47 is a revision of an earlier progress report, the revision being based
primarily on the findings of Task 41. The entire programue was conducted under
several tasks which are briefly mentioned below.
Task 38—Sub-basin hydrogeological reconnaissance studies: Report findings,
mainly of a qualitative type, showed generally low base-flows for the streams. There
is probably little groundwater discharge from the sub-basins which is not measured
in stream-flow.
Task 39—Seismic exploration of groundwater resources: This project consisted of a seismic survey along six selected valley cross-sections. Four sections
were run to the north and two to the south of Okanagan Lake.
Task 40—Groundwater exploration in the main valley, deep and medium-deep
rotary test-holes and observation-well installations: Under two contracts, a total of
nine holes was drilled, ranging from 120 to 1,890 feet deep. Eight of these were left
completed as observation wells ranging from 320 to 1,215 feet deep.
The above tasks were undertaken in 1970.
Task 41—In the summer of 1971, well cleaning, well development, test pumping, and instrumentation of the eight holes left completed as observation wells were
carried out. Hydrograph records are now being obtained following upon instrumentation of the wells.
Task 47—This involved evaluation of various task findings and previously obtained information, and integration of several reports into a volume to be produced
as Technical Supplement II Groundwater Studies in the Okanagan River Basin.
Kalamalka-Wood Lake Basin Water Resource Management Study
A programme of field investigations was initiated in March and terminated in
October of this year. The field programme was preceded by an office study of available groundwater information on file.
Fifty-six sites, comprising 51 wells and five springs, were initially selected for
water sampling. After field mapping in the Wood Lake area, 15 wells and five
springs were liminated, and 13 new springs were added to the sampling programme.
Forty-four new observation wells for water sampling were installed under four
separate drilling contracts between March and October. Thirty-three of these new
wells were installed under the supervision of a consultant in the spring of the year.
Of the remaining 11 wells from which water samples are being collected, seven were
installed by the Groundwater Division and four by participating personnel from the
Department of Civil Engineering, University of British Columbia. Thirteen of these
new observation wells have been mounted with automatic water-level recorders, and
monthly water-level readings are being taken on the other 31 wells.
Under a fifth contract put out by the Groundwater Division, a total of five
pumping tests was run, ranging from periods of eight hours to 48 hours.
The objective of this part of the programme is to try to determine the role of
groundwater in nutrient input into Wood and Ellison Lakes. The wells selected for
study, and the locations of new wells, have been designed to monitor
(1) groundwater flow and water-quality changes in the more densely

Gulj Islands Groundwater Study
A preliminary groundwater report was compiled early in the year for Mayne
Island. The report included preliminary estimates and recommendations for the
1972 field season. Bedrock and structural geology, hydrochemistry, watershed, and
populations distribution work sheets were prepared for the Gulf Islands early in the
year based on available information, and these sheets were used for subsequent field
and office studies. During the field season, 278 water-quality samples were collected from springs and wells. These samples were analysed, compiled, and tabulated by Groundwater Division personnel using a Hach Water Engineers' laboratory
kit. Hydrogeological mapping was carried out in the field on Mayne, Saturna,
Galiano, and Pender Islands.
A decision was made to undertake an extensive programme of groundwater
investigations on Mayne Island to further evaluate groundwater supplies both as to
quality and quantity and to also formulate practical techniques for subsequent
groundwater assessment of the other Gulf Islands.
A contract was let and work was completed on an experimental geophysical
survey of Mayne Island. Both seismic and resistivity surveys were run across fault
zones to delineate the width and inclinations of the zones.
An intensive programme of drilling, pump-testing, and down-hole geophysical
logging was completed on Mayne Island during the field season.
Seven 6-inch-diameter wells were drilled using an air rotary rig on selected
sites, after evaluation of geological, seismic, and surface geophysical results. Well
depth varied from 200 to 500 feet.   All wells were artesian, with five flowing.
Wells encountering salt water were successfully grouted to the fresh-water zone
or completely grouted to prevent contamination of the fresh-water aquifers.
Pumping tests of one to eight days' duration were carried out in five of the
drilled wells, using the Department's equipment. Results reveal that at least one
well can sustain continuous pumping of 30 U.S. gallons per minute during the "dry"
season, with an acceptable drawdown. This is the highest known well yield on the
island.
Down-hole geophysics, utilizing various tools, were carried out on the new
wells. Results indicate that fracturing is responsible for most of the water-bearing
zones. It also indicated that caliper and density tools gave the most consistent
results and interpretation.
Five automatic water-level records were installed on the wells to provide continuous monitoring throughout the year. These observation wells will give immediate
changes in water-table conditions and enable the Department to further evaluate
long-range groundwater conditions.
Compilation, tabulation, and graphical presentation of data continue toward a
detailed groundwater report on this work.
A groundwater consulting firm was also engaged to make a groundwater study
of Gabriola Island. Field operations, test drilling, and pumpings were completed
and a report is expected shortly.
Work has also commenced at the Department of Geological Sciences, University of British Columbia, on the compilation of a bedrock and structural geology map
of Saltspring Island under terms of an agreement made with the university.

Miscellaneous
A short field inspection and subsequent report outlining recommendations for
groundwater development were completed for the YMCA proposed outdoor recreation centre on Saltspring Island.
Consultative services were given to the Pollution Control Branch, and included
(1) a short field inspection and a subsequent meeting to discuss the
groundwater-flow system and water-well monitoring requirements
needed at the site of a proposed sanitary landfill operation in the
Municipality of Matsqui; and
(2) preliminary meetings in Victoria and Vernon to discuss and review
existing reports and basic data concerning nitrate content of groundwater supplies at Rutland.
In addition to the activities outlined above, considerable staff time was spent
on attending to numerous inquiries concerning all matters dealing with groundwater
in the Province.
Groundwater Division personnel gave two addresses on the results of groundwater programmes at the north end of the Okanagan Valley to the Canada-British
Columbia Okanagan Basin Study "Workshop Seminar" in Vancouver. The Division
Chief gave a presentation of groundwater studies, conducted under the Canada-
British Columbia Okanagan Basin Agreement, to a public seminar at Naramata. The
Division Chief took part in a panel discussion and gave a short presentation on
Groundwater Division functions at a one-day seminar for "Continuing Education of
Engineers" held at the University of Victoria. The Division Chief read an address,
prepared by the Deputy Minister of Water Resources, to the Second Annual Convention of the British Columbia Water Well Drillers' Association.
Groundwater Division engineers attended a surficial geology field excursion in
British Columbia organized by the 24th International Geological Congress.
ARDA DIVISION
J. V. Eby, P.Eng., Chief of Division
The ARDA Division was formed in 1963 for the purpose of investigating
water-project proposals and preparing submissions under the Federal-Provincial
Agricultural and Rural Development Act (ARDA) assistance programme.   The
 Y 90
B.C. WATER RESOURCES SERVICE
work carried out by the Division includes design and construction supervision of
certain projects, as well as processing of claims and maintenance of records relating
to ARDA water projects.
The British Columbia Department of Agriculture is charged with the over-all
administration of the ARDA programme. Under an interdepartmental co-operative
arrangement, the British Columbia Water Resources Service is responsible for implementation of ARDA water projects, which responsibility has been delagated to the
Water Investigations Branch. The third Federal-Provincial ARDA Agreement
signed in 1970, covers projects over the period 1970 to 1975.
Projects varying in cost from $10,000 to over $8,000,000 have been completed
or are bemg constructed under the ARDA programme. Construction periods vary
from under a year to five years or more. Construction is carried out either by district
crews or under contract. Design and construction supervision of projects has been
undertaken by various organizations, including the ARDA Division and Water Supply and Investigations Division of the Water Investigations Branch, the Water Rights
Branch, the Federal Government Indian Affairs Branch and PFRA organizations
and consulting engineers.
_ Up to 1970, most ARDA water projects were concerned with rehabilitation of
irrigation systems and storage works, the majority of which are located in the Okanagan Valley. Work of the Division now includes drainage, flood control, and
similar reclamation-type projects.
Since the start of the ARDA water-projects programme in British Columbia in
1963, a total expenditure of $34,200,000 has been authorized, and some $31 -
000,000 actually expended on approved ARDA water projects. In addition a
further $800,000 has been expended on projects for which final approval is awaited
Actual and potential water projects under the ARDA programme total 87 in
number and, of these, 65 have been approved by Federal and Provincial authorities
and 22 are under study prior to a possible proposal submission or awaiting approval
Forty-nine projects have been completed and 14 are presently under construction

Of the projects under construction, four were brought into full operation during
the year and may be considered complete in the construction sense. The 14 incomplete projects mostly have construction periods exceeding one year, some of
which will not be completed until 1974 or later. Some of the completed projects
have still to submit final claims for reimbursement in respect of such items as contractors' holdback, and legal and survey costs pending.
Project descriptions following will be given only for those which are actively
under study or where significant changes have taken place during 1972.
ARDA Projects Essentially Completed During the Year
1. Keleden Irrigation District Supplementary (ARDA Project 89002)—The
main project serving irrigation and domestic water to about 535 acres was constructed during 1966 and 1967 under ARDA Projects 10013, 29015, and 29015(S).
The supplementary project involved replacement of the remaining sections of short-
life pipe-lines in the distribution system. Design was carried out by the ARDA
Division, with construction by district forces. This additional work will bring final
cost of rehabilitation to about $373,000.
2. Keremeos Irrigation District (ARDA Projects 29027 and 89007)—This
project involved replacement of the original gravity supply from the Ashnola River
and Keremeos Creek with a groundwater pumping system. Two batteries of wells
pump into the east and west systems to provide irrigation and farm domestic water
to some 1,220 acres of land. The supplementary project completed this year supplies outlying lots to the west of the main systems with irrigation and domestic water
from separate wells. Design was by the ARDA Division, and construction was
carried out mainly by district forces.   Final cost of the project is about $660,000.
3. Vernon Irrigation District (ARDA Projects 29004, 29004(S), and 89019)
—Construction of a new pressurized irrigation and rural domestic-water supply system for the Vernon Irrigation District began in 1966, and has been essentially completed in 1972. The new system supplies water to some 10,000 acres and includes
over 100 miles of new pipe-lines, 12 pumping stations, three chlorinating stations,
and several pressure-reducing stations.
Work completed in 1972 included reconstruction and repairs to the Haddo
Lake Dam, intake structure, and spillway, as well as completion of the main intake
dam at Headgates.
Design of the system was by the ARDA Division, and construction by district
crews, with some contract work.   Final cost of the project is about $8,000,000.
4. Otter Lake Waterworks District (ARDA Project 89004)—Construction of
a new farm domestic-water supply system for the Otter Lake Waterworks District
commenced under contract in late 1971 and was completed during 1972. The system provides farm domestic water to about 40 farms from a groundwater well. The
approved cost of the project was $99,000.
An extension to the project to the RSM area north of the district will be constructed during 1973 under ARDA Project 89027.
ARDA Projects Under Construction or Study
1. Southern Okanagan Lands Irrigation District (ARDA Projects 10010,
29041, 29041 (S), and 29051)—This rehabilitation programme was implemented
to upgrade the existing 5,000-acre irrigation system of the Southern Okanagan Lands
Project, which is presently Provincially administered. Water is diverted to the system from Okanagan River near the south end of Vaseux Lake by means of a
 Y 94 B.C. WATER RESOURCES SERVICE
concrete-lined canal. Systems 1, 4, 5, 6, and 7 pump from the main canal, systems
2 and 3 pump from groundwater wells, and systems 8 and 9 pump from Osoyoos
Lake.
Work carried out in 1972 included continuation of a programme of installation of Dole flow-control valves in an effort to control over-use of water. Repairs
were also made to the No. 9 pumphouse near Osoyoos, to overcome cavitation problems during periods of low water and high system demand.
Remaining work to be completed under a proposed supplemental project include modications to pumping systems Nos. 1 and 4, and completion of the programme of Dole valve installation. Additional work which may be included will be
repairs to the main canal and reconstruction of the No. 5 pumphouse.
The estimated final cost of the project is about $3,400,000.
2. South East Kelowna Irrigation District (ARDA Project 29053)—This
project was approved in June of 1970 and construction commenced in September
1971. The project consists of a completely rehabilitated water system to supply
irrigation water under pressure to 4,336 acres and domestic water to 660 homes
at an approved cost of $3,600,000.
The main features of the water system consist of upstream storage and diversion
works to provide the annual requirement of 12,700 acre-feet of water; a diversion
dam and settling pond on Hydraulic Creek; chlorinator; 18,600 feet of 42-inch-
diameter supply line, and two distribution systems, containing approximately
150,000 feet of pipe, ranging in size from 4-inch to 30-inch-diameter; and 27
pressure-reducing and pressure-relief stations.
The construction of the upstream reservoir structures is being carried out
under the direction of the Water Supply and Investigations Division, and that
portion of the project is described more fully under the report of that Division. The
design and construction supervision of the distribution works is being carried out
by the ARDA Division, as well as the Pooley and Myra diversion works.
The Pooley diversion canal, approximately 4.5 miles in length, will divert
water from Pooley Creek into the McCulloch Reservoir via the Myra Ditch. Construction of the canal is nearing completion and will be in partial operation for the
1973 irrigation season.
During 1971, designs were completed and tenders awarded for the supply of
18,600 feet of lines and coated 42-inch-diameter steel pipe and related accessories.
The installation of this pipe-line was virtually completed by district crews in 1972.
This line will be tested and put into operation in the spring of 1973.
Designs were completed in 1972 for the intake dam on Hydraulic Creek which
will provide a small reservoir for balancing storage and settling pond, and an intake
with mechanical travelling screens. Construction consisted of completion of the
concrete gravity spillway and excavation of the intake pond and dam-site.
The intake tower, earthfill dam, and chlorinator will be constructed in the
spring of 1973.
Designs were completed and tenders awarded for the supply of materials for
the S.K.L. and K.L.O. main lines which consist of 23,500 feet of pipe ranging in
sizes from 18- to 30-inch, and for nine pressure-reducing stations. These works will
be completed for the 1973 irrigation season. The completed system is scheduled
to be completed and into operation by mid-1974.
3. Robson Irrigation District (ARDA Project 89020)—The Robson Irrigation District provides irrigation water to 110 acres of land, and domestic water to
about 45 farms and 260 residential water-users. During 1968 and 1969, the district
completed the first two phases of reconstruction of its works under ARDA Projects
 WATER INVESTIGATIONS BRANCH
Y 95
29029, 29029(S), and 29039.   This work involved replacement of approximately
10,000 feet of 12-inch pipe-line and improvements to the intake works.
The final phase of the project under ARDA Project 89020 was partially completed in 1971 with installation of about 5,000 feet of 10-inch pipe-fine, and all
replacements will be completed early in 1973. Design of the project was by consulting engineers. Final cost of rehabilitation under all four projects is estimated
to be $216,000.
4. Otter Lake Waterworks District, RSM Extension (ARDA Project 89027)—
The Otter Lake Waterworks District reconstructed its water-supply system in 1972
under ARDA Project 89004, at a cost of $99,000. Subsequent to approval of this
project, the property-owners in the adjacent RSM area petitioned for inclusion within
the Otter Lake Waterworks District and received ARDA approval for the extension
in August 1972, under ARDA Project 89027. The estimated capital cost of the
proposed extension is $125,400, which includes an allowance for increasing the
capacity of the main supply system to meet the increased water demand.
Design of the project has been carried out by consulting engineers and construction is scheduled for 1973.
5. Deadman Creek Irrigation District (ARDA Project 89021)—This project
involves construction of a storage dam and control structure located at the outlet
of Snohoosh Lake, which will provide 4,000 acre-feet of operating storage. Released
storage water during the irrigation season will supplement low flows in Deadman
Creek, and water will be pumped or diverted at various points downstream to
irrigate bordering fields.
The project was approved in August 1972 at an estimated cost of $126,000.
Design of the project will be by consulting engineers under the direction of the
Indian Affairs Branch of the Department of Indian Affairs and Northern Resources.
6. Coldwater Indian Band Irrigation Project (ARDA Project 89022)—This
project was approved in August 1972 at an estimated cost of $301,000. The
project involves construction of a dam on Midday Creek to develop a storage
capacity of 1,400 acre-feet. Two separate pumping systems are to be constructed
downstream of the storage dam for irrigation of some 800 acres within the Cold-
water Indian Reserve 2.
Design of the project will be by consulting engineers under the direction of the
Indian Affairs Branch of the Department of Indian Affairs and Northern Resources.
Other Studies
Irrigation
1. Corporation oj the District oj Summerland water-supply system rehabilitation—The Corporation of the District of Summerland supplies irrigation water to
about 3,600 acres of land and provides domestic water to about 2,000 connections.
During the period 1965 to 1969 the district completed reconstruction of four of its
ten storage dams and replaced parts of its main flumes under ARDA Project 10029.
The storage reservoirs provide about 10,500 acre-feet of storage from the watersheds of Trout Creek and Eneas Creek.
The major part of its irrigation supply system consists of open flume and ditch,
which is in need of replacement. A feasibility study was, therefore, undertaken by
the ARDA Division in 1971 to determine extent and costs for rehabilitation of the
district system, including work required on the remaining storage dams. This study
has been essentially completed in 1972 and will be presented to the district early in
1973.   The study considers the possibility of incorporating its existing separate
 Y 96 B.C. WATER RESOURCES SERVICE
domestic-water supply system with the proposed works, as well as including the
supply of water to the Trout Creek Irrigation District from the system.
2. Headquarters Road Irrigation District—A feasibility report on a proposed
irrigation and domestic-water system for the Headquarters Road Irrigation District
is being prepared by the ARDA Division. The district proposes to supply irrigation
water to about 750 acres of land within the district. Two sources of water are being
considered—supply from groundwater wells, and an alternative supply from the
Tsolum River with storage development on Wolf Lake.
3. Chase Irrigation District—The district has requested a report be prepared
to recommend improvements to its intake and supply main from Chase Creek, as
well as a review of its water supply and storage requirements. This report is under
preparation by the ARDA Division and will be presented to the district early in
1973.
The district supplies irrigation water to 635 acres of land from an intake on
Chase Creek. About 500 acre-feet of storage are provided on Pillar Lake. The
report considers replacement of the existing wood-stave supply main and intake,
and installation of more effective screening works.
4. Vernon Irrigation District, Grizzly Swamp Diversion—A feasibility report
and cost estimate on a proposed dam and diversion canal for the Vernon Irrigation
District is being prepared by the ARDA Division. The Vernon Irrigation District
has reconstructed its distribution system and storage works under ARDA Projects
10005, 10030, 29004, and 89019 for a total cost of about $8,040,000. The above
projects included rehabilitation of King Edward, Haddo, and Aberdeen Lake Dams.
Recent information on water use by the district has indicated that additional storage
may be required, and the district has requested a study of development of additional
storage on Grizzly Swamp. The project would also include a diversion canal from
the Grizzly Swamp Dam into Aberdeen Lake, which, at present, fills only during
years of above-normal run-off.
Surveys and mapping for the proposed project have been completed during
1972 by the Water Supply and Investigations Division and the final report will be
presented to the district early in 1973.
Drainage
The staff of this Division has been employed on secondary drainage schemes
designed to complement the main drainage provided for under the Fraser River
Flood-control Programme. Such studies have been undertaken as a result of requests
for ARDA assistance from the areas concerned.
1. District oj Surrey Drainage and Irrigation Scheme, Nicomekl River South
(168th Street and 40th Avenue)—A completed study proposing drainage and
irrigation improvements to benefit some 2,000 acres has been forwarded to the
District of Surrey for approval. The study area is located within the Nicomekl-
Serpentine flood plain where potential benefits may be obtained from intensified
vegetable production. Scheme improvements include channel rehabilitation, new
ditches, flood-boxes, and two pump stations, all of which will control flooding and
the height of the water table within the study area. Costs have been estimated at
$997,900.
2. District oj Surrey Drainage and Irrigation Scheme, Nicomekl River North
(168th and 52nd Avenue)—Another combined drainage and irrigation study has
been forwarded to the District of Surrey for approval, which includes channel rehabilitation, new ditches, floodboxes, and two pump stations.   The study area is
 WATER INVESTIGATIONS BRANCH
Y 97
again located within the Nicomekl-Serpentine flood plain, affecting some 1,500
acres intensively used for vegetable production. Scheme costs have been estimated
at $795,300.
3. District oj Matsqui, Matsqui Prairie Drainage Scheme — A watershed
totalling 43.75 square miles was investigated in order to provide a drainage scheme
to benefit some 9,661 acres of agriculture land. The benefiting area is located
within the Fraser River flood plain, where dairy production is predominant. Improvements will include channel rehabilitation, new ditching, drop structures, sand-
gravel traps, and one pump station all designed to control flooding and the height
of the water table within the study area. The proposed scheme would complement
the internal drainage improvements scheduled for completion under the Fraser River
Flood-control Programme.   Costs have been currently estimated at $1,799,000.
4. Township oj Chilliwhack, Castleman Road Drainage Scheme—The study
of the Castleman Road area has been completed in 1972. The proposed scheme
covers two adjacent watersheds having a combined area of 2,060 acres. The land
is gently undulating, and the predominant form of agriculture is dairying. The proposed scheme consists of a system of ditches that would provide gravity drainage
into Hope Slough, which is the major drainage channel for the region. The cost of
the scheme would be approximately $145,000.
5. Township oj Chilliwhack, Chadsey Ditch Watershed—To gain information
on the run-off from agricultural land, a study was undertaken of the discharge from
a 320-acre watershed during the winter of 1971/72. The final analysis of the data
is under way.
BASIN PLANNING AND POWER DIVISION
J. D. Watts, P.Eng., Chief of Division
This Division of the Water Investigations Branch has two main functions—the
development of plans for water management on a regional or watershed basis and
the inventory of the undeveloped water-power potential of the Province. The following work has been done during the past year:
Water-management Studies
Creston Flats Monitoring Programme
Construction of the Libby Dam on the Kootenai River in the United States is
now completed and the filling of its reservoir was partially achieved in 1972. From
this time onward, changes will take place in the flow pattern of the river in British
Columbia. Notwithstanding one of the heaviest snow-packs on record prior to the
1972 freshet, there was no threat of spring flooding by the river to the 21,000 acres
presently protected by dykes at Creston. However, if British Columbia is to take
full advantage of the improved river regime in increased power production by hydroelectric plants on the lower Kootenay River, possible changes in storage levels on
Kootenay Lake must be considered. Investigation of the consequences of changes
in river regime and possible changes in lake storage-levels on the dyked areas at
Creston is the subject of an extensive monitoring programme commenced in 1969.
To date, the following work has been done:
1. In co-operation with the Groundwater Division, a total of 71 observation
wells within the dyked areas was installed or rehabilitated, as reported previously.
The resident well-reader made a total of 24 circuits of the well system in 1972. Data
collected are tabulated and plotted in preparation for comparison with future years.
 Y 98 B.C. WATER RESOURCES SERVICE
2. Each of the four dyking districts is protected by two pumping-stations. In
co-operation with the station operators, data on pumping-time and power consumption are being collected on a continuing basis.
3. Infrared and panchromatic air photography, river and lake levels, local
precipitation records, and other information are being collected for correlation and
evaluation in conjunction with data provided by the observation wells.
It is anticipated that this continuing programme will supply basic data for
future evaluation of the effect of river and lake levels on the water table of the
agricultural lands and its effect, if any, on crops in the area.
Similkameen River Flood Plain
Due to a record snow-pack, combined with heavy rainfall, record high peak
flows occurred in the Similkameen River during the 1972 freshet period, and extensive flooding problems were experienced. As part of a programme to develop suitable flood-control measures in the Similkameen Valley, an outline of the areas
affected by the 1972 flood was prepared, based on air photographs obtained during
the freshet, supplemented by a field survey made at the time of peak flows. An
outline is also being prepared showing those areas which would have been flooded
if the present dyking systems did not exist, or if emergency action had not been
taken.
North Thompson River Flood Profile
In order to establish criteria for dyke-crest elevations in the Kamloops area, a
design flood profile was calculated for a flood having a frequency of recurrence of
once in 200 years. This flood profile was initially calculated from Kamloops Lake
upstream to Kamloops on the Thompson River and up the North Thompson River
to the Canadian National Railways bridge. The profile was subsequently extended
upstream to Rayleigh Mount at the request of the Thompson-Nicola Regional District, and following a further request, will be extended to the vicinity of Clearwater
Station.
Multiple Use oj Watersheds
A Task Force on Multiple Use of Watersheds of Community Water Supplies
was established under the Technical Committee, Environment and Land Use Committee, to investigate the practicability of obtaining wholesome water supply from
streams having watersheds which are subject to multiple use, and to recommend
policy and procedures for consideration of such land-use conflicts.
In support of the task force, various functions have been carried out, as follows:
1. A list of water sources for cities, districts, towns, villages, improvement districts, regulated water utilities, and water-users' communities in the Province was
compiled.
2. A general map was prepared showing the locations of watersheds used for
community water supplies throughout the Province.
3. A questionnaire regarding multiple-use conflicts has been distributed to the
operators of all public waterworks systems in the Province. Correlation and evaluation of the resulting information will be carried out early in 1973.
4. Plotting outlines of water-supply watersheds on large-scale mapping, and
showing also the legal status of the lands involved, has commenced.
5. Administration and co-ordination assistance to the task force have been
provided.

East Kootenay Study
A report on the results of a preliminary appraisal of the water resources of the
East Kootenay study area was prepared during the year. The study area, located in
southeastern British Columbia, was defined by the Environment and Land Use
Committee. The report provided information on the availability and use of the
water resource in the study area. In addition, the general and specific problems
concerning the resource, including conflicts with other resource-users, were examined.
The report was briefly summarized in the Report on the East Kootenay Study
Area Number 4 by the Technical Committee, Environment and Land Use Committee.
Fraser River Agreement Studies
The following tasks under the Fraser River Upstream Storage Study were
assigned to the Water Investigations Branch and carried out under the direction of
this Division.
Task 1 is to update the cost estimates of System E projects proposed in the
Final Report of the Fraser River Board, 1963, including, where necessary, further
field investigations and revised designs.
Progress during the year is as follows:
1. Lower McGregor Project—The results of the 1971 field investigation programme were contained in a report by G. E. Crippen and Associates Limited, Consulting Engineers to the Service, entitled "Report on Fraser River Investigations,
Lower McGregor Project, February, 1972."
Further field exploration work and office studies were carried out in 1972
under the supervision of G. E. Crippen and Associates Limited, as follows:
(a) The drilling programme which was commenced in 1971 was continued by Inspiration Drilling, Division of Dresser Industries Canada
Limited, to further assess conditions in the infilled river channel
adjacent to the dam-site. Two holes were drilled, totalling 1,556
lineal feet, in overburden and 28 lineal feet in bedrock. Further
drilling work was subsequently carried out by this contractor in the
same general area under the supervision of International Power and
Engineering Consultants Limited, Consulting Engineers to the British
Columbia Hydro and Power Authority. The two programmes were
co-ordinated and the resulting data were mutually exchanged.
(b) Nine bulldozer trenches, totalling approximately 16,000 lineal feet,
were excavated on the south and west edges of the infilled valley.
The materials thus exposed were mapped and sampled.
(c) A seismic investigation programme for the British Columbia Hydro
and Power Authority was combined with a similar programme for
the Service and carried out by Geotronics Surveys Limited under the
supervision of G. E. Crippen and Associates Limited, to obtain information on the bedrock configuration of the infilled valley. A total
of 45,000 lineal feet of seismic traverses was completed along six
lines. The results of this investigation are contained in Geotronics
Surveys Limited report entitled "Seismic Investigation for Proposed
Dam Site, Lower McGregor Project, July 1972."
(d) A portion of the Parsnip River valley, through which the flow of
the McGregor River system would be diverted by the proposed proj-
 Y 100 B.C. WATER RESOURCES SERVICE
ect, was examined to determine the existence of possible dam-sites
to provide regulation of the diversion flows and enhance power production at the Peace River dams, both existing and proposed. The
study consisted of an air photograph analysis followed by a brief
field examination of possible dam-sites.
(e) Preliminary office studies were undertaken of control and generating
works at various sites on the Parsnip River.
The results of these investigations are being assessed and it is anticipated that
a report will be completed early in 1973.   A preliminary assessment of the results
indicates that control of seepage through the infilled valley at the Lower McGregor
dam-site is feasible.
2. Hemp Creek Project—In 1971 a programme of field exploration work was
carried out to further assess the likelihood of seepage paths being established, after
filling of the reservoir, through an infilled valley lying to the east of the dam-site. The
investigations included both subsurface investigations and surface reconnaissance.
The results of these investigations were contained in a report by G. E. Crippen
and Associates Limited, Consulting Engineers to the Service, entitled "Report on
Fraser River Investigations, Hemp Creek Project, February 1972." This report
concludes that the permeability of the basalt is variable, but that leakage through
this rock would not likely be significant, and that leakage of the reservoir through
the alluvial materials, or underburden, infilling the valley beneath the basalt would be
insignificant and would be unlikely to result in piping or other erosion downstream of
the dam. The report also states that further investigation of the basalt and underburden is unnecessary prior to the design stage of the project.
Task 2 requires that a benefit-cost analysis be made of upstream dyking requirements necessary to provide protection against design floods. To this end, the
Basin Planning and Power Division has undertaken the tasks of preparing preliminary
designs and cost estimates for dykes which may be necessary in the Kamloops, Prince
George, and Quesnel areas. This work is almost complete and a report should be
completed early in 1973.
Progress in 1972 is as follows:
(a) Kamloops—Preliminary design for 116,500 feet (22 miles) of dykes
and bank protection, where required, has been completed and cost
estimates for constructing these dykes have been made.
(b) Prince George—Preliminary design for 24,500 feet of dykes and
necessary bank protection have been completed and cost estimates
have been prepared.
(c) Quesnel—Preliminary design for 12,900 feet of dykes, together with
required bank protection, have been completed and cost estimates
have been prepared.
Miscellaneous
1. The system of review of applications for Crown land purchases, leases, and
reserves to determine possible water-resource management conflicts was continued.
Some 350 applications were reviewed.
2. Assistance was rendered to the water-quantity studies forming part of the
Okanagan Basin Agreement studies.

Hydro-power Investigations
Liard River
Detailed office studies of the hydro-power potential of the Liard River in British
Columbia continued during the year. A report was completed covering two alternative schemes of development which would limit the maximum level of the upstream
reservoir to prevent flooding of the community of Lower Post and limit flooding in
the Yukon to approximately 600 acres. The first scheme consists of dams at Site J,
near Mile 505 of the Alaska Highway and at Site A, some 30 miles upstream from
the mouth of the Fort Nelson River. The second scheme is comprised of dams at
Site A and Site E, located 17 miles downstream from Lower Crossing.
The report includes a comparison between these schemes and the scheme of
development comprised of three dams at Sites A, E, and G, which was the subject
of a report in 1970, and which involved the relocation of Lower Post and substantial
flooding in the Yukon. It is indicated that the development costs for the three
alternative schemes are almost equal, involving a total capital cost of some $1.45
billion in 1972 dollar values and that the average annual energy production for each
scheme is about 23.5 million megawatt hours. Average at-site energy costs, based
on 1972 prices and an interest rate of 6 per cent, varied between 4.1 and 4.3 mills
per kilowatt-hour for the three schemes.
A report is being prepared on the results of studies which investigated the
power potential at Site X, located on the main stem of the Liard River some 10
miles downstream from the mouth of the Fort Nelson River. Site X was considered
in the study as a possible downstream addition to the development schemes outlined
above.
Other Activities
The Chief of the Division was a member of the Fraser River Joint Programme
Committee from its inception in 1968 until its disbandment in November 1972. The
Committee held nine meetings in 1972 prior to its disbandment, which was due to
administrative changes instituted to simplify implementation of the Fraser River
Flood Control Agreement dated May 24, 1968.
PROJECTS DIVISION
J. D. C. Fuller, P.Eng., Chief of Division
The Projects Division has as its main function the investigation, review, and
implementation of major flood-control, land-reclamation, erosion-control, and drainage projects. This includes work in connection with the 1968 Fraser River Flood
Control Agreement.
In addition, the Division designs and supervises construction of water-damage
prevention projects, either directly or under agreement with local authorities or
individuals.
Exceptionally high run-off occurred in 1972, both within the Fraser River
watershed and elsewhere within the Province, and a large part of work within the
Division during the year comprised investigation of resulting river flooding and
erosion, and implementation of remedial measures. The Similkameen Valley, in
particular, suffered considerable flood damage.
Lower Fraser Valley Flood-control Programme
In April the present Chief of Division took over from P. M. Brady, who
assumed the position of Assistant Chief Engineer (Technical). At that time, respon-
 Y 102 B.C. WATER RESOURCES SERVICE
sibility for the implementation of construction under the Joint Federal-Provincial
Fraser River Flood Control Agreement (1968) was transferred from ARDA Division to the Projects Division. Representation on the Joint Programme Committee
remained with Mr. Brady in his new position. Later in the year, upon disbandment
of the Joint Programme Committee, the co-ordination of design under the Rood
Control Agreement was also transferred to the Projects Division. This transfer
applied with effect from December 1, 1972, thus placing the responsibility for both
design and construction of projects with one organization.
Under the new arrangement, co-ordination of each project is carried out by a
project manager who co-ordinates design both by outside consulting engineers and
design groups within the Division. He also maintains liaison with respective local
authorities and other agencies.
In general, work by the Division design groups comprises design and preparation of contract documents for bank protection, and preparation of basic design
criteria for dyke and drainage works, for which outside consultants prepare final
designs and contract documents.
To date, applications for assistance with flood-control works under the programme have been received from the following municipalities or local authorities:

Province before the start of construction.
Design work at various stages is proceeding in respect of a further seven
projects.
Work connected with construction aspects of the Federal-Provincial Fraser
River Flood-control Programme, while still not growing as fast as expected, continued to form a large part of the Division's activities during the year.
 WATER INVESTIGATIONS BRANCH

The majority of construction is carried out by contract, with field supervision
by either staff of the Division or consulting engineers. Assisting Victoria staff with
both over-all administration of the construction phase and field supervision is a
staff of seven, operating from an office located in Abbotsford.
During the year, work continued at the Districts of Kent and Matsqui, the two
projects so far to reach the construction phase. In addition, emergency bank-protection works, to be cost-shared under the programme upon completion of an
agreement, were carried out under contract at the Canoe Pass area of Delta and
at Seabird Island near Agassiz.
During the year, contracts totalling $1,134,000 were awarded, and claims
totalling $1,088,000 were processed under the programme.
The following descriptions are given for projects under way:
District oj Kent—This project was approved on December 12, 1969, at a construction cost of $2,003,825, and an agreement for cost-sharing between the Province and local authority signed on February 20, 1970. In December 1971, the
approved cost was increased to $2,185,825.
Main features of the project comprise some 7,000 feet of new bank protection,
20,000 feet of bank-protection repair work, 62,000 feet of dyke reconstruction, and
reconstruction of two pumphouses having a combined horsepower of approximately
207. In addition, the project includes some relatively minor ditch, floodbox, and
culvert rehabilitation work.
Construction during 1972 comprised completion of the last major bank-protection contract and minor work at the pumphouses. Preparation of legal survey plans
showing dyke rights-of-way continued during the year. By the end of the year, this
project was complete except for completion of surveys and "as-constructed" drawings.
District oj Matsqui—This project was approved on June 28, 1971, at a construction cost of $2,283,600, and an agreement for cost-sharing between the Province and local authority was signed on October 29, 1971.
Main features of the project, as approved, comprise some 38,000 feet of dyke
reconstruction, with a relief trench and drainage system along most of its length,
riprap repair work to some 2,700 lineal feet of river bank, and internal drainage
works. The drainage works include the replacement of two pumphouses with
combined floodbox and pumping facilities having a total installed horsepower of
approximately 850.
Late in 1971, two contracts covering bank protection and most dyke works were
awarded, totalling $1,024,000. In July 1972 a third contract covering the floodbox
and pumping facilities and some dyke work was awarded at $1,098,744.
By the end of the year the bank protection was complete, including some emergency work in the Ridgedale area. Work on the floodbox and pumphouse facilities
was approximately 50 per cent complete, with the prospect of operation in time for
the 1973 freshet. Work on the dykes, however, was only about 30 per cent complete, having been stopped in August due to local objections to the proposed seepage
trench design. On December 27, 1972, a revised contract was concluded allowing
for construction of a berm in place of a seepage trench to deal with seepage problems.
Completion of the major part of these works was scheduled prior to the 1973 freshet.
Lower Squamish Valley
The major part of work completed during 1972 in the Lower Squamish Valley
comprised continuation of the Squamish River Training Works, part of a harbour
 Y 104
B.C. WATER RESOURCES SERVICE
development of the British Columbia Railway, for which this Division provided
engineering and management services.
Construction of the training works, designed by Swan Wooster Engineering
Company Limited for the Province, was implemented in three phases—extension of
the flood-control dyke, dredging the new river channel, and completion of the dyke
and timber pile wall guide.
Phase 1 construction, costing $317,000, commenced in October 1971, and was
completed in late January 1972. The works were constructed by District of Squamish forces with technical assistance from Projects Division staff.
Phase 2, comprising dredging of the main river channel, was completed under
contract during January and February 1972 at a cost of $602,000.
Phase 3 consisted of extending the training dyke, constructing a piled structure
at the end of the training dyke, and raising the flood-control dyke, also completed by
contract. The cost was $902,800 and construction was carried out between January
and June 1972.
The total cost of the completed training works, including miscellaneous works
and engineering, amounted to almost $2 million, shared equally by the railway
company and the Province.
In addition to the river-training works, further construction was carried out in
the Lower Squamish Valley as part of a continuing flood-control programme.
During the year, district forces, under direction of staff of the Division, completed
$33,000 of bank-protection work on Mamquam River. This brings to some
$680,000 the value of such flood-control works carried out since commencement
in 1968. Completion of this programme would require an estimated additional expenditure of some $1,900,000.
Bella Coola Valley
Work on a comprehensive study pertaining to river flooding and erosion on the
lower Bella Coola River and side streams between Bella Coola and Hagensborg,
initiated in 1968, continued during 1972 and was nearing completion at the end
of the year.
In response to local requests, dyke and bank-protection work was carried out
during May, June, and August at a cost of $35,000. This comprised extension of a
dyke previously constructed by the Department of Highways, located some 2 miles
upstream from Hagensborg on the Bella Coola River. The work was carried out
by locally recruited forces, directed by staff of the Projects Division.
Cowichan River Flooding
A preliminary report on flooding and erosion by the Cowichan River at Lake
Cowichan and in the Lower Cowichan Valley was completed in 1967. Any further
action on proposals contained in this report await the results of studies by the Federal
Fisheries Service on the economic value of the Cowichan River as a fishery resource.
Kitimat River
Work continued on the preparation of a report on flooding problems in the
Kitimat Valley. This was ready in draft form by the end of the year.
Lumby
In accordance with proposals contained in a flood-control report prepared in
1969, further work was completed during 1972 valued at $13,000.   Local forces
 WATER INVESTIGATIONS BRANCH
Y 105
were employed, directed by staff of this Division.  This substantially completed the
programme, with costs over the period 1970/1972 amounting to $100,000.
Grand Forks
In accordance with a report on flood control for the City of Grand Forks,
completed in March 1972, Phase 1 comprising dykes and bank protection on the
south bank of the Kettle River was completed between May and October of 1972.
Work was carried out by contract, supervised by staff of the Projects Division, and
cost $65,000. The total cost of flood-control works within the city limits envisaged
in the report amounts to some $240,000.
Other River-flooding and Erosion Projects
The exceptionally heavy spring run-off throughout the Province resulted in 76
requests for assistance regarding flooding and erosion problems. By far the largest
number of requests came from the Similkameen River watershed.
Of the applications during the year, 38 were investigated and reported on, 26
were inspected with a report pending, and 12 remained to be investigated at the
end of the year. The investigations resulted in 12 projects under construction during
the year, excluding the Squamish, Lumby, and Grand Forks projects.
Construction, comprising dyke and bank-protection work, was carried out by
contract, with design and supervision by staff of the Division. The value of work
amounted to $161,000.
The investigations included the areas of Buck Creek and Bulkley River at
Houston, where extensive damage resulted from the spring run-off. Remedial work
estimated to cost some $160,000 is anticipated early in 1973. Erosion by the Fraser
and Quesnel Rivers at Quesnel was also investigated, and remedial work estimated
to cost $170,000 has been proposed.
Other areas under investigation include the Pemberton Valley, Nicola and
Coldwater Valleys, Eagle River, Upper Kettle River, North Thompson and Clearwater Rivers, Columbia River at Golden, Mission Creek in the Okanagan Valley,
and Strachan Creek at Howe Sound.
Miscellaneous
During 1972, technical assistance and advice were provided to Provincial
Government and other agencies in connection with road and bridge construction,
sale of land, and zoning and flood-plain definitions.
ECOLOGY DIVISION
R. J. Buchanan, Ph.D., Senior Biologist
The permanent staff complement of the Ecology Division was expanded to three
with the appointment of an additional biologist in February. Three other biologists
were appointed as temporary summer assistants in May.
The capabilities of the Division were substantially increased by the procurement
of a research boat and various scientific instruments.
Technical Reviews
Several technical reviews were carried out during the year—
(1) ecological aspects of the Squamish Harbour development proposed
by the British Columbia Railway;
 Y 106 B.C. WATER RESOURCES SERVICE
(2) a review prepared by a consultant under contract on the mechanical
control of aquatic weeds;
(3) the preliminary design for a proposed lake water-quality monitoring
programme was prepared (details were worked out and equipment
was procured for the collection of additional limnological information by survey parties in the Water Supply and Investigations Division); and
(4) a large body of literature on the biology and control of aquatic weeds
was assembled and studied.
Field Studies
The Ecology Division assumed responsibility for aspects of three field studies
during the year—
1. Specifications were prepared for the water-quality and limnology aspects of
the Kalamalka-Wood Lake Basin Water Resource Management Study. The Division is executing certain tasks related to algas. The bulk of the field work has been
contracted to consultants, but the Division bears continuing responsibility for
liaison and quality control.
2. A consultant was commissioned to carry out limnological surveys of Langford Lake, near Victoria, preparatory to detailed studies on aquatic weeds and
their control.
3. Extensive and intensive field studies by staff biologists on the biology of
aquatic weeds are continuing. The programme was expanded to include Windermere
Lake, all major lakes in the Okanagan Valley, and selected small lakes near Victoria. These studies have involved surveys of weed distribution, the kinds of weeds,
and such habitat characteristics as water depth, water exchange rate, water chemistry, sediment chemistry, sediment texture, and associated plants and animals.
These measurements have required many man-hours of SCUBA diving. They are
being assisted by the Water Supply and Investigations Division, which is preparing
very accurate bathymetric maps of certain areas of intensive study.
Services to Citizens
The Branch receives intermittent appeals from citizens or groups of citizens
who are experiencing water-resource problems.
Those problems which have been assigned to the Ecology Division for investigation have included the following:
1. A complaint was received about the deterioration of Kathlyn Lake near
Smithers. The data on file in various agencies were investigated and comments on
the lake's condition were offered.
2. Advice was requested on the possibility of improving the quality of water
in Boitano Lake, a saline lake near Williams Lake. The data on file in various
agencies were reviewed, the site was inspected, and suggestions were offered.
3. Advice was requested on the control of leeches and algse in beaver ponds
near Likely. Technical information was provided along with suggested means for
dealing with the problems. Advice was offered on the appropriate steps in securing
approval for the control measures from regulatory agencies.
4. Intermittent scientific observations continued on Tie Lake, near Cranbrook,
where investigations had started in response to complaints received in 1971.
 WATER INVESTIGATIONS BRANCH
Y 107
During the year a request was received from the Peace River-Liard Regional
District for literature on eutrophication and its control. Actual publications could
not be provided, but a reference list of reading material was prepared.
Consultative and Liaison Services
Personnel of the Ecology Division provided consultative services to various
officials and government bodies.
1. Information and scientific opinion was provided to Forest Service officials
on the water-quality effects of flooded forests.
2. Advice was provided on the capabilities of ships-of-opportunity for measurement of oceanographic properties in coastal waters.
3. Advice was provided on the value of a biological water-quality monitoring
programme, and on the required specifications of a satisfactory system.
4. Advice was provided on the water-quality aspects of a water-supply system
for the proposed Dease Lake townsite.
5. Division personnel advised and co-operated with the Okanagan Basin Water
Board on the design and execution of a weed-harvesting experiment in Okanagan
Lake near Vernon. Division scientists assisted the Water Board in the collection of
technical information to be used to evaluate the effectiveness of this method of weed
control.
6. The Senior Biologist acted for part of the year as secretary to the Fraser
River Ecology Committee, which is examining the ecological aspects of upstream
storage under the Fraser River Flood-control Programme. In the course of these
duties a minor advisory role was also played.
7. Staff biologists are pursuing discussions with weed scientists in the Provincial
and Federal Departments of Agriculture, with a view to initiating joint studies on
chemical control of nuisance aquatic plants.
The Senior biologist represented the Province of British Columbia at a symposium on lakes of Western Canada held in Edmonton in November. At that meeting, he outlined some aspects of lake management in British Columbia.
Reports
During 1972, reports were prepared on the following subjects:
(1) A report for the Kalamalka-Wood Lake Basin Water Resource Management Study on the status of weed infestations in Kalamalka Lake:
(2) A preliminary report on the quality of various waterbodies in the
vicinity of the proposed Dease Lake townsite; and
(3) Two reports on the biological studies in Windermere Lake (one final,
one in draft stage).
RECORDS COMPILATION AND REPORTS SECTION
A. S. Stencel, R.I.A.
The Records Compilation and Reports Section is responsible for the assembly
of engineering reports, operation of the Reports Library, collection and compilation
of technical and cost records, operation of the Branch motor-vehicle pool, and general duties for the Branch.
A review of the statistics of the Section will indicate that the year 1972 has
again been one of growth. This continues a trend that has been evident since the
Water Investigations Branch was created 10 years ago.

A detailed account of the activities of the Reports Library and the General
Office which make up the Section follows.
Reports Library
The main functions performed by the Reports Library during 1972 included
the reproduction, registration, and distribution of all engineering reports required
as well as the maintenance of related records. During the course of the year the
Library received 113 new engineering reports for assembly and registration. In
addition to the new reports, 650 other copies of reports have been prepared and
distributed as compared with 450 in 1971.
Set out below is a numerical and percentage summary of reports written during
10-year periods:

While no micro-filming of reports was undertaken during 1972, plans have
been made for the filming of 250 reports during the next year.
Throughout 1972 the Reports Library again handled over 500 requests for
report loans and copies of other publications.

machinery, materials, and supplies were prepared and over 1,800 invoices from suppliers processed for payment.
The General Office staff also assisted in the processing of claims for various
water projects under construction and in the collection and compilation of technical
and cost records.
In addition, the General Office provided mail and messenger service, handled
the shipping of instruments and supplies to field parties, and operated the Branch
motor-vehicle pool. A review of motor-vehicle records shows that Branch units
travelled in the past 12 months again more than 400,000 miles on over 430 assignments.
As a result of the move of some Division offices from Cook Street to the location
on Broughton Street, mail delivery routes have been shortened.
Early in 1972 the Branch vacated the Government parking at 937 View Street
and relocated its motor-vehicles to the Provincial Service Centre at 805 Cloverdale
Avenue. Toward the end of the year and following the allocation of additional
space, all Branch boats, trailers, and ski-doos were also moved to this new parking
area.
DRAUGHTING OFFICE
B. Varcoe, Chief Draughtsman
The year 1972 was the year of the big move. On July 19, the ARDA Division,
including the draughting section, moved to new offices at 765 Broughton Street. At
the same time, the main Water Investigations Branch draughting section moved
from the Blanshard Building to 765 Broughton Street. These moves finally placed
all but two draughtsmen of this Branch in the same office, thus improving the efficiency and versatility of the draughting section.
Draughting production for 1972 has been very good, not only due to the
amalgamation of the draughting staff, but also because there have been no changes
in personnel.
The following list shows the amount of draughting done by sheets. While the
total looks tremendous, it must be stated that approximately 30 per cent are small
sheets and also that possibly 50 per cent of all drawings were additions or amendments to already printed base sheets. Also included are 30 large display-type sheets
and three small uncontrolled mosaics.

BOARD
V. Raudsepp
Chairman
The principal functions of the Pollution Control Board are to act in an advisory
capacity to the Government, to set standards for controlling pollution, to act as an
appeal tribunal in case of an appeal from an order of the Director of Pollution Control Branch, and to consider acceptability of the objections to applications for permits which, under the provisions of the Pollution Control Act, 1967 cannot be made
directly to the Director of the Pollution Control Branch, or directly to the Greater
Vancouver Regional District with respect to air pollution control permit applications
with the boundaries of the Greater Vancouver Regional District, as provided in the
1972 amendments to the Pollution Control Act, 1967.
During the year 1972 the Board held 12 meetings, at which a total of some 115
items of business received attention.
The Board heard four appeals from the orders of the Director of the Pollution
Control Branch, of which on two occasions the Board decided against the Director
and allowed the appeals.
A number of objections to applications for permit (a total of 86) were reviewed
by the Board under section 13 (6) of the Pollution Control Act, 1967.

Assistant Director
The Pollution Control Branch was formed in 1967 under a Director of Pollution Control who is responsible for the day-to-day administration of the Pollution
Control Act, 1967, as amended, to regulate the discharge of liquid, solid, and
gaseous wastes to water, land, or atmosphere respectively, in a manner that will
not exceed the assimilative capacities of the receiving environment and hence cause
pollution.
To implement these responsibilities, four division were established—Municipal
Division, Industrial Division, District Division, and Projects and Research Division.
The reports for 1972 from each of these divisions will follow and a report of activities of the administrative support services.
The control of waste discharges in British Columbia is through the issuance of
permits which has involved such waste-management functions as detailed study of
waste sources, possible waste elimination and reuse, and assimilation of waste into
the receiving environment.
Over the past three years the Branch has been working toward a procedure
whereby the basic waste-management principles for wastes from the most common
activities in the Province are standardized through the involvement of the public,
industry, and Government agencies. The objectives established through this procedure and after review by the Pollution Control Board are used as minimum requirements for waste-management practices and they will form the basis on which
most applications for permits will be considered.
REPORT BY THE DIRECTOR
Three public inquiries were held in 1972 to further establish specific discharge
objectives and guidelines for the control of pollution. This is a continuation of the
programme initiated in 1970 with the Forest Products Inquiry to set discharge
objectives for all sectors of major industry and for municipalities requiring pollution
control permits. The three inquiries held during 1972 started with the mining and
smelting industries in March at Cranbrook for the first part, then moved to Vancouver for the remainder. This inquiry was followed by the chemical and petroleum
industries inquiry held in May at Vancouver, and subsequently by the food processing and agriculturally oriented industries inquiry held in November at Kamloops.

 Y 118 B.C. WATER RESOURCES SERVICE
The last of this series of inquiries is scheduled to be held in Victoria in April
1973 and will cover municipal discharges. Following this, it is proposed to hold
similar inquiries on a, say, five-year basis into the same activities to reaffirm and
upgrade where necessary the minimum objectives that were established.
The reports covering the objectives from the mining and smelting industries
and the chemical and petroleum industries are nearing finalization and expected to
be released in early 1973.
During the past year there was one public hearing held by the Directors' office
relative to a specific application for permit. In addition, an appeal hearing against
an order of an engineer under the Act commenced in late 1972.
A deep-seated fire at a landfill located in the Millstream area of Langford near
Victoria became the object of an extensive research project when it became evident
that the operator of the poorly operated landfill was not able to extinguish the fire.
This research project was primarily concerned with developing and carrying out a
procedure for extinguishing a landfill fire and, secondly, to develop operating and
design criteria to minimize the occurrence of such fires in landfills. The fire was successfully extinguished under the co-ordination of the Pollution Control Branch
through funds provided by Water Resources Service, and a report covering this
project is being prepared by Projects and Research Division.
During 1972, 332 applications for permits and 38 applications for permit
amendments were received. Of these, 166 permits were granted, including 73
additional appendices to permits for those operations having more than one discharge, 61 amendments to permits were issued, 24 applications for permits or permit
amendments were refused, and 36 were voluntarily withdrawn, leaving 321 pending
applications at year-end being processed or awaiting resolution or administrative or
technical details. In most instances, permits granted required the applicant to
provide additional facilities and controls to those set out in the original application.
This brings to 641 the number of permits now in force under the Act.
The Pollution Control Act, 1967, as amended, also requires that a certificate
be obtained from the Minister of Lands, Forests, and Water Resources for the construction of sewerage works. A total of 452 requests for such certificates was received by the Minister in 1972 and referred to this Branch for advice. Of that total,
502 certificates have been issued, including 93 carried over from 1971, while 45
are still pending, awaiting additional technical or administrative information.
During the January 1972 sitting of the Legislature, two substantial amendments
were made to the Pollution Control Act, 1967. The Greater Vancouver Regional
District was empowered under the Act to regulate the control of discharges or
emissions to the atmosphere within that regional district in accordance with the
jurisdiction and authority provided by the Pollution Control Act, 1967. Amendments to the Act also authorized the Director of Pollution Control to issue approvals
for waste discharges of short-term duration not exceeding six months, instead of
issuing a permit. Approvals are considered primarily for discharges from transient-
type operations with a planned termination date where a decision regarding the
discharge must of necessity be made in a short period of time. Approvals for a total
of 50 operations were issued by the Directors' office upon the investigation and recommendations of District Managers.
The Legislature also approved the addition of 100 positions to the existing 85
positions previously authorized for the Branch. The Directors' office was extensively
involved with allocating the various positions authorized and securing the personnel,
approximately two-thirds of which were of professional background.
 POLLUTION CONTROL BRANCH Y 119
With the large increase in work load it was necessary to expand the Directors'
office by the addition of two Assistant Directors, each of whom have powers equivalent to those of the Director, but with day-to-day work associated primarily with
administrative and with technical matters respectively. Also closely associated with
the Directors' office are the newly established positions of Chief Technical Officer
(Air) and Chief Technical Officer (Water and Land). These positions undertake
the functions previously a principal responsibility of the Chief Engineer, the review
and co-ordination of technical assessments and recommendations of permit applications for consideration of the Director.
The large increase in staff, 70 of which were located in Victoria Main Office,
necessitated additional accommodation for which expansion of the previous accommodations was arranged.
The Directors' office commenced, during 1972, the procedure of issuing orders
to certain dischargers to make application for permits under the Act. These orders
were to persons who had registered their discharges in accordance with previous
requirements of the Act, and they were issued on the basis of what were considered
to be priority waste-discharge problems as determined by District Managers.
During 1972, orders to apply for permits were issued to a total of 220 operators
covering 505 registered discharges, of which 265 were for emissions, 165 were for
effluent, and 75 for refuse.
The continuation of the policy, commenced in 1971, of requiring, in most permits issued, monitoring by the permittee and receiving-environment monitoring by
Branch staff necessitated continued development of the data storage and retrieval
programme in co-operation with the Data Processing Centre.
Miscellaneous activities involving the Directors' office were participation in
holding and attending meetings, on-site inspections, and presentation of talks.
PROJECTS AND RESEARCH DIVISION
M. W. Slezak, P.Eng., Chief of Division
The Division was reorganized and restructured in April of 1972 to include
three sections (Land and Water, Air, and Ecology) as well as a support services
group.
The number of Division personnel expanded from a previous total of 12 in
1971 to 36 in 1972 to form a multidisciplined group. The Air Section complement
consists of 10 engineers, two meteorologists, and four technicians, while the Land
and Water Section has a total of 10 people with backgrounds primarily in chemical
and environmental engineering complemented by one chemist, an agricultural engineer, and an agronomist. The Ecology Section has a total of six personnel, consisting of one chemist and five biologists with backgrounds ranging from physical,
biological, fish physiology, to terrestrial ecology. The support services group is
comprised of three draughtsmen, who provide a draughting service to all Branch
personnel, and a laboratory technician in the Water Resources Service Chemistry
Laboratory.
This past year has been extremely active as the Division developed procedures
and guidelines and provided assistance as required to the two application-processing
divisions and the District Division. Considerable time was expended in familiarizing
the large number of new staff to government policies and Branch procedures.
As indicated in the 1971 Annual Report, the initial responsibility for developing air expertise within the Branch was given to the Projects and Research Division.

 POLLUTION CONTROL BRANCH Y 121
In this regard a familiarization programme was undertaken on all aspects of air-
pollution control.
The Division continued actively to participate and represent the Branch in
major studies such as the Federal-Provincial Okanagan Study, the Libby Dam
water-quality study, Naramata water-quality study, and Provincial interagency
studies.
Another major role of Division personnel in 1972 has been their participation
in two major inquiries into waste discharges related to the mining, mine milling, and
smelting industry and the agriculturally oriented, food processing, and other miscellaneous industries.
The Division has a wide range of responsibilities, with primary involvement in
the following to
(1) develop and update discharge objectives for effluent, solid wastes,
and emissions;
(2) develop and assess guideline monitoring programmes for the receiving air, land, and water environment;
(3) develop, supervise, assess, and (or) consult on environmental monitoring programmes initiated in the interests of the Branch;
(4) assist in the continuing development of a computer service in cooperation with the Provincial Data Centre for pollution control permit and environmental monitoring data;
(5) co-ordinate, supervise, and assess applied research being carried out
for the Branch;
(6) develop a continuing education programme for Branch technical
personnel;
(7) provide, on request, technical advisory service to all other Divisions;
(8) undertake all other related duties and assignments as required.
Air Section
The Air Section continued to provide assistance to the Industrial Division in
the processing of applications. In addition, the section was active in developing
ambient air and stack sampling objectives and sampling programmes, in reviewing
and assessing reports and in training new personnel.
A principal function of the Air Section in 1972 was to provide a comprehensive training programme to prepare new staff for possible assignment to other divisions within the Branch.   Training included all aspects of air pollution, including
(1) isokinetic stack-sampling techniques to enable personnel to determine
the concentrations of particulates and gases in the stack emissions;
(2) ambient air monitoring, instrumentation, and methods to permit
personnel to determine the concentrations of particulates and gases
in the ambient air;
(3) meteorological instructions to enable personnel to calculate the dispersion characteristics of stack gases under varing meteorological
conditions and determine the concentrations at the point of impingement;
(4) instructions on the use of mechanical collectors, wet collectors, cloth
filtration and electrostatic precipitators to reduce the discharge of
particulates to the atmosphere;
 Y 122 B.C. WATER RESOURCES SERVICE
(5) special courses on the emissions from kraft mills, wood-waste burners, the mining industry, and chemical and petrochemical plants;
(6) a study of the effects of air pollution on vegetation.
Assistance was provided to the Director at inquiries conducted into waste discharges into the air environment.
The major projects undertaken by the Air Section in 1972 were
(1) the evaluation of two high-volume samplers used to measure the
particulate matter emitted by a modified teepee burner;
(2) the installation of the mobile laboratory at Squamish, B.C., to determine the concentration of sulphur dioxide, suspended particulate,
and chlorine in the ambient air;
(3) the design and development of a second mobile laboratory for determining concentrations of contaminants in the ambient air; it is proposed to utilize this laboratory throughout the Province;
(4) assistance to the district offices in site selection of ambient air-monitoring stations in a number of communities;
(5) preparation of a manual detailing stack-sampling procedures;
(6) preparation of a report on continuing education of Branch personnel;
(7) improvising of a special study on the effects of meteorological and
topographical influences on air pollution in the Province;
(8) preparation of ambient air-monitoring programmes with respect to
industrial discharges to be used as guidelines by other divisions of
the Branch.
Land and Water Section
Major functions of this Section are to provide assistance to all Branch divisions
and carry out certain applied research projects related to discharges to land and
water.
The work carried out during 1972 covered the following main areas:
(1) Assistance was provided to the permit application-processing divisions and district offices on subjects relating to effluent and refuse
disposal:
(2) Evaluation of data and development of water-management alternatives for the year 1980 were completed for the Okanagan Basin Study
in conjunction with other Provincial and Federal Government
agencies; other work carried out included a water-quality study and
the relationship of water quality to land use:
(3) A fire at the Millstream landfill resulted in a research project being
conducted by the Division in conjunction with the Directors' office:
(4) The section was represented on the panel of the public inquiry into
waste discharges from the food processing, agriculturally oriented,
and other miscellaneous industries; guidelines for discharges from
these industries are in the process of being established:
(5) Monitoring guidelines for receiving waters were prepared in relation
to discharges from all types of industrial and municipal wastes in
conjunction with other sections of Projects and Research Division
for use by the District, Municipal, and Industrial Divisions:
(6) A report on possible contamination of water within the Naramata
watershed by grazing cattle was completed:

(8) Oil-spill contingency plans were studied and a preliminary plan for
British Columbia was drawn up:
(9) The Section participated in the Environment and Land Use Committee Technical Subcommittee, which reported on indiscriminate
dumping of refuse:
(10) Experiments were initiated at the University of British Columbia on
leaching from landfills:
(11) Supervised experimentation on surface area determination of Hat
Creek coal to assess its suitability as a waste-water treatment media:
(12) Initiated and supervised a three-year applied research programme
into animal-waste disposal on
(a) establishing criteria for land disposal of cattle, piggery, and
poultry wastes from industrialized operations;
(b) treatment of cattle and piggery wastes from industrialized
operations where space is limiting;
(c) odour control of animal wastes emanating from industrialized operations.
Other work initiated in 1972 included a study of Rutland groundwater quality,
an evaluation of foaming problems on the Thompson and Nicola Rivers, a preliminary investigation of effluent charges for discharges to air, land, and water, and
evaluations of several waste-water treatment units and processes for the Processing
Divisions.
Ecology Section
The Ecology Section was established in 1972 to handle the ecological aspect of
pollution control. Through 1972, assistance was given to the Industrial and Municipal Divisions in the assessment of applications and permits, and in the assessment of
monitoring programmes proposed or being carried out by permittees or by independent agencies. Guidance and instructional supervision were given to the district
offices in the development and implementation of biological and water-quality monitoring programmes, in the use of specialized equipment, and in the procedures and
techniques for new methods of sampling and analysis. Assistance was also provided
to the Director at public inquiries into waste discharges associated with various
activities and in the subsequent preparation of reports
The principal projects undertaken by the Ecology Section in 1972 include the
following:
(1) Implementation, in co-operation with the Kootenay District Office,
of a detailed biological and water quality study for the Kootenay
River and its major tributaries, with regard to the construction of
Libby Dam in the United States:
(2) Implementation and completion at the request of the Deputy Minister of a preliminary survey of dissolved-gas supersaturation levels
in selected Provincial waters:
(3) Further development in co-operation with the Data Processing Centre and with the Chemistry Laboratory of a computer storage and
retrieval system; this system, once completed, will store and create
records of pertinent information and of monitoring data for all applications and permits and for all environmental monitoring sites:

MUNICIPAL DIVISION
J. E. Dew-Jones, P.Eng., Chief of Division
The past 12 months have seen a change in the organization following a substantial staff increase. The Division has now been split into three sections—Coastal,
Southern Interior, and Northern and Central Interior, headed by R. Schurr, P.Eng.,
D. Corrigan, P.Eng., and P. Bardal, P.Eng., respectively. The Coastal Section
covers Vancouver Island, the Greater Vancouver area, and communities north to
Ocean Falls, thereby encompassing the majority of sea discharges within the Province. The Southern Interior Section covers the remainder of the Lower Mainland,
togther with the Okanagan-Kootenay areas and, accordingly, encompasses a large
proportion of those communities which live near lakes of recreational value. The
remainder of the Province, south to Kamloops and Merritt, lies in the Northern and
Central Interior Section, which, therefore, includes those areas where problems due
to extreme climatic conditions are located. On the average, each section handles
the applications for discharge of effluent and refuse from a total of 56 municipalities
and regional districts plus private domestic discharges within their boundaries and
in addition processes requests for certificates authorizing sewer construction.
During 1972 an increase of 11 staff brought the Division to a total of 19 persons, all with engineering background. Considerable effort was involved in acquiring
and assimilating the new employees into the organization while maintaining the flow
of applications requiring processing.
The new organization should allow substantial progress on two essential aspects
of pollution control in the Province. First, a routine examination of all permits to
discharge has been instigated and upgrading of discharges will be required where
necessary. An essential preliminary to this work is the monitoring of both discharges and receiving environmental parameters, and for some time it has been the
Directors' policy to require such monitoring programmes on permits issued. Reports on programmes of general interest which are now available include a study
 POLLUTION CONTROL BRANCH
Y 125
of the effect of the Clover Point discharge and new Macaulay Point discharge in
the Greater Victoria area by a University of Victoria team; also a record of pre-
discharge conditions in the main arm of the Fraser by a B.C. Research Council team
in connection with discharges by the Greater Vancouver Sewerage and Drainage
District.
Secondly, the Division has commenced recommendations to the Director of
Pollution Control Branch leading to orders for applications to be submitted by those
who have registered a discharge but not yet applied for a permit. A system of
priorities enables the most important of these discharges to be dealt with first, and
the programme will continue until all registered discharges are covered. The total
number of such registered discharges of nonindustrial origin is approximately 1,200.
The last of a current series of public inquiries will be held in Victoria, commencing April 30, 1973, and Division personnel have already been involved in
preparations. This last inquiry will be in connection with municipal-type waste discharges and it is intended to determine better the measures which must be adopted
by dischargers of such wastes to ensure satisfactorily that pollution will not be
caused. Submissions have been invited and specific matters which it is hoped to
cover include
(a) acceptable quality characteristics and control requirements to be
met for effluent discharges to
(i) the marine environment, including estuaries;
(ii) fresh water;
(iii) the land by surface disposal;
(iv) the land by subsurface disposal;
(b) the acceptability of discharging raw or partially treated effluent
through long sea outfalls designed to meet defined standards, the
criteria that should be applied, and the extent of investigation that
is necessary;
(c) the acceptability of discharging effluent from storm overflows, the
controls that are necessary, and the need to remove surface water
and (or) infiltration from sewer systems to enable quality criteria to
be met;
(d) the control of connections to sewer systems to enable quality criteria
to be met;
(e) acceptable controls for the disposal of refuse to land (including disposal of leachate) and the extent of investigation that is necessary;
(/) acceptable controls for the emission of contaminants arising from
disposal of refuse by incineration.
Numerous meetings were held between staff members and applicants during
the year. While the Division cannot instigate proposals on behalf of municipalities
or private dischargers, a great deal of guidance is given to applicants on the basis
of Board policy, precedents already set, and the wide base of experience available
with the Division.
Although the increase in staff was limited until the year was somewhat advanced, the number of applications for permits and amendments which were processed increased to 130 from 95 in the previous year, while the applications in hand
have increased from 80 to 160 and there are now over 200 authorized secondary
treatment plants for treating domestic wastes. The number of requests for certificates for sewer construction processed during the year was 502, compared with 400
last year.

Y 126 B.C. WATER RESOURCES SERVICE
Coastal Section
The Coastal Section includes the three major population centres of Vancouver,
Saanich Peninsula, and Nanaimo, all of which have major pollution control projects
under way. These include extensions to the Iona Island treatment plant, sewerage
scheme for the Central Saanich area, and a plant and major trunk sewers for
Nanaimo. All told, 38 applications for permits or amendments have been processed
and 357 sewer-construction certificates issued; 18 orders to submit applications were
initiated by the Section.
Southern Interior Section
Apart from extensions and upgrading to many treatment plants, a great deal
of investigative work has now been carried out regarding discharging refuse by
municipalities, including regional districts. Of particular interest is the study carried
out in the Trail area and the first-class sanitary landfill operation now under way
for the City of Vernon. There are several proposals to dispose of sewage effluent
by spray irrigation, and in particular an experimental scheme is now being operated
also by the City of Vernon. During 1972, 63 applications for permits or amendments were processed and 67 sewer construction certificates issued. Fifty-three
orders to submit applications were initiated by this Section in 1972.
Northern and Central Interior Section
In the Prince George area, the secondary treatment plant is now well under
construction. Beyond the bounds of the sewer system, in order to overcome the
difficulties of effluent disposal where there is no suitable watercourse and the land
is impervious, a number of private dischargers have sought to store effluent through
the winter to spray irrigate in summer. This approach has been proven elsewhere
and is attractive in some ways. A number of permits have now been issued using
conservative designs and, if shown acceptable in this area, the input can be expected
to become more widely used in future.
Also of note is the work done by regional districts in promoting refuse-disposal
schemes which satisfy Pollution Control Branch requirements while being economically feasible. In 1972, 29 applications for permits or amendments were processed
and 78 sewer-construction certificates issued. Orders to apply for permits were
initiated for 11 operations.
INDUSTRIAL DIVISION
H. P. Klassen, P.Eng., Chief of Division
The function of the Industrial Division of the Pollution Control Branch is to
process applications for pollution control permits from the industrial sector of the
Province. This includes the manufacturing portion of the forest products industry,
the mining, and milling industry, the petroleum refining and processing industry,
agriculture and food-processing operations, chemical manufacturing, and all miscellaneous manufacturing and servicing operations that have potential discharges
to air, water, or land of waste products other than domestic wastes and traditional
farming wastes.
In the assessment of applications, a thorough inplant examination of the
plant or operation is made to reduce, and eliminate where possible, the sources of
wastes and to determine where wastes may be effectively reused. Subsequently,
outplant treatment and necessary disposal of the wastes are investigated to deter-
 POLLUTION CONTROL BRANCH Y 127
mine whether or not they can be discharged into the receiving environment in accordance with the policies and objectives established by the Pollution Control Board.
During 1972, in excess of 150 meetings and discussions were held with representatives of industry on matters related to pollution control permit amendments
and applications. In addition, meetings were held with other Provincial and Federal agencies. Numerous industries were inspected throughout the year. Division
staff were directly involved with two public inquiries dealing with industrial-type
wastes and in preparing objectives and guidelines for the allowable waste discharges.
A continuing function of the Division is to review registrations of existing discharges to the ground, water, and air and initiate applications for pollution control
permits. In this regard, orders have been issued and negotiations have been carried
out on a priority basis to ensure that improvements to existing discharges are
achieved where the environment is considered to be most seriously affected.
During 1972, 228 applications were received and 81 permits and 16 permit
amendments were granted; 218 applications were being processed at year-end, and
four applications were refused during the year.
A concentrated effort has been put into the reduction of contaminants emitted
to the air. Notable is the mass conversion of the old type of wood-waste burner
to the modern modified type with controlled combustion. Real improvements
should be felt in all areas of the Province by the latter part of 1973.
Expansion of the Division in 1972 has been extensive with an increase from
seven engineers to 26 engineers with training and (or) experience in pulp, and
paper, mining, smelting, milling, petrochemicals, chemical, and agricultural disciplines. The related experience includes operation, design, research, and in some
cases, management. It is now possible to evaluate most of the industries operating
in the Province with respect to waste discharges from their activities.
Forest Products Section
During the past year, 138 applications for permits and amendments to permits, comprising 61 for air emissions, 40 for refuse, 26 for effluent, and 11 amendments to existing permits were received from various segments of the forest products
industry. To date, this has culminated in the issuance of 38 permits and amendments to permits, made up as follows: 16 air emissions, 12 refuse, 6 effluent, and
5 amendments to permits plus two refusals. In connection with these, monitoring
programmes to assess the effects of the various discharges on the environment have
been incorporated as a condition of the permit. The balance of the applications
on hand are in various stages of processing, with 17 of these in their final stages.
Of considerable value to both the Branch and the forest products industry are
the minimum objectives for waste discharges adopted by the Pollution Control
Board in late 1971. These have provided a starting point for new industry in applying for application and are an indication to existing industry as to the requirements they will be required to meet in the future.
Staff increases in 1972 resulted in seven additional engineers being added,
bringing the total number of staff to 10 in this section, most of whom have experience in the forest industry.
Three new kraft pulp-mills, after a delayed start-up due to the strike in the
construction industry this past summer, came on stream during the latter part of
the year. All three mills have incorporated the most recent technological advances,
which should allow them to meet Level A of the Pollution Control Objectives for
the Forest Products Industry of British Columbia for discharges to the land, water,
and air.
 Y 128 B.C. WATER RESOURCES SERVICE
Mining and Mineral Products Section
During 1972, 16 pollution control permits were issued by the Mining and
Mineral Products Section. Of these, seven were issued for discharges of effluent,
eight were for emissions into the air, and one was for the discharge of solid refuse
to land.
Thirty-nine other applications are in various stages of processing.
In addition to new permits issued, two amendments to existing permits were
issued and five were being processed at year-end. Fifty-eight companies registered
in 1971 a total of 530 existing discharges in compliance with the Pollution Control Act, 1967.
The Section was involved in a technical capacity, with the public inquiry into
the activities of the mining, mine-milling, and smelting industry with regard to pollution matters which was held by the Director in early 1972. Subsequent to the inquiry, the Section continued to be involved in the formulation of the recommended
objectives, which are expected to be completed in early 1973.
It is anticipated that a number of the existing permits will require amendments
to bring them into compliance with new objectives for effluent and air quality
which will be outlined in the forthcoming report on Pollution Control Objectives for
Mining, Mine-milling, and Smelting Industries.
In the last quarter of 1972 the section commenced processing applications
from sand and gravel, concrete aggregate, and placer-mining operations. During
the year, five major mining operations and two medium-sized operations went into
production.
During 1972, staff increases brought the total number of staff in the Section
to seven engineers from four engineers in 1971.
General Section
The General Section completed processing 51 applications during 1972. Of
these, 31 new permits were issued, 9 permits amended, and 2 applications refused.
The remaining applications were withdrawn as a result of connecting the discharges
to municipal sewer systems.
The first permits were issued for air emissions in 1972, and it is of interest
to note that the number of separate emissions from the larger industries ranges from
5 to 100 each, whereas the number of effluent discharges seldom exceeds two.
A major segment of the food-processing industry in the Province is represented by the fish-processing companies. Most of the major processors submitted
applications based on a staged programme for upgrading effluent quality over a
two- or three-year period.
The General Section was involved in a technical capacity with the Director's
public inquiry in the chemical and petroleum industries held in early 1972 and
subsequently in the development of the recommendations from that inquiry which
have not been finalized at year-end.
Staff of the General Section increased from three engineers in 1971 to 10
engineers in 1972, and the expertise of the Section now comprises a wide diversity
of training and experience to deal with the broad range of waste applications handled
by this group.

DISTRICT DIVISION
R. H. Ferguson, P.Eng., January 1 to April 30, 1972
A. A. Hayman, P.Eng., May 1 to December 31, 1972
For the District Division, 1972 was a year of growth, change, and expansion
of Division activities. In May, R. H. Ferguson, P.Eng., was promoted to the position of Assistant Director (Administration), and A. A. Hayman, P.Eng., was appointed to the position of Chief, District Division. During the year the Division
staff increased from 38 persons to 62 permanent staff and in addition 12 temporary staff were assigned to various district offices to assist in handling the increased
summer work loads. The additional permanent staff provided expertise in various
phases of engineering; biological and environmental technologies related to air,
land, and water-waste disposal and environmental monitoring, and facilitated the
carrying-out of an increased work-load related to permit application site inspections,
inspection of sewerage works, expansion of environmental monitoring programmes,
and surveillance in the areas of Pollution Control Branch responsibilities.
The increased surveillance programme has enabled district offices to bring
about improvements to a number of problem discharges and, where negotiations
have failed, a number of prosecutions have been initiated.
During 1972 the Division staff undertook to determine the approximate number of gaseous emission within the Province that were not registered in accordance
with the Pollution Control Act, 1967. On the basis of a sample inventory it was
estimated that approximately 1,000 nonregistered emissions exist in addition to
the 1,300 registered emissions in the Province, excluding the 941 registered discharges within the Greater Vancouver Regional District.
The organization of the District Division is now made up of the Division
Chief's office, with his assistant in Victoria; the Coast District office in Victoria,
with a field office in Courtenay; the Lower Mainland District office in New Westminster; the Kootenay District office in Cranbrook, with a field office in Nelson; the
North District office in Prince George, with a field office in Fort St. John; the Okanagan District office in Vernon, with a field office in Penticton; the South Central
District office in Kamloops, with a field office in Williams Lake. The decentralization
of the district offices has facilitated closer liaison with the public, more effective
surveillance of dischargers under permit, and better coverage of the Province by
the staff in undertaking continuing environmental assessment programmes initiated
by the Branch.
The 1972 amendment to the Act transferring jurisdiction of air pollution control in the Greater Vancouver Regional District to the regional district's authority
has allowed the Lower Mainland District staff to place additional emphasis on their
air-monitoring programmes in other problem areas in the district. The amendment to section 5 of the Act relating to the Director's authority to grant approval
for waste discharges from temporary installations has resulted in an increased workload and responsibility for Division staffs in inspecting and assessing proposed
sites and facilities, making recommendations to the Director, and ensuring compliance with conditions of the approval.
During 1972 the general public took greater advantage of the information and
assistance provided by the district offices. Application forms were made available
at district offices and greater assistance was given to prospective applicants for
pollution control permits and to persons requesting information related to general
pollution control and environmental matters.
The reports of the district offices are as follows:

four to 10 members with the addition of one Biologist, one Engineer, two Technicians, and two Engineering Assistants. Two additional Engineers were temporarily
employed at the office prior to permanent assignment to divisions in Victoria.
A total of 47 pollution control permits was currently being administered by the
South Central District office, 15 of which were issued in 1972 (nine existing permits
have been superseded or are no longer required). Inspection and sampling of
waste-treatment facilities under permit was conducted on a regular basis. A total
of 29 site inspection reports for permit applications was prepared, and 29 new applications are now being processed. Eleven additional inspections were conducted
to determine suitability of proposed refuse-sites. Five approvals for temporary discharge under section 5c of the Pollution Control Act, 1967 were issued in 1972.
Eleven orders were issued to dischargers in the district by the Director to make
application for permits under the Pollution Control Act, 1967.
An inventory of emissions to the air was conducted and 115 unregistered
discharges were recorded.
The water-quality monitoring programme started in 1971 was expanded to a
total of 87 stream-sampling stations and 35 outfall-sampling stations. In addition,
a lake-sampling programme was initiated at seven stations on four lakes in the district.
An ambient air-monitoring programme was also started in 1972 with 19
stations set up in four urban areas. A programme for sampling emissions to the
air at source is planned for 1973.
Several special projects were undertaken, including an inventory of septic-tank
pumpage discharges and a preliminary investigation into abnormal foaming in a
river.
Numerous complaints were investigated and many requests for information and
advice were received during the year.
Kootenay District
L. N. Adamache, P.Eng., Manager
The Kootenay District is responsible for the administration of the Pollution
Control Act, 1967 in the Regional Districts of East Kootenay, Central Kootenay,
and Kootenay Boundary.
The District office and laboratory are located at 1617 Baker Street, Cranbrook,
with a suboffice at 711 Stanley Street, Nelson.
The staff were increased from eight in 1971 to 11 in 1972, with two of the
additional staff located in the Nelson field office. Considerable time was spent by
existing staff in orienting and training new arrivals.
Field inspections and reports were completed on 50 applications for permits
and permit amendments. Thirty-two permits were approved in 1972, making a
total of 70 permits for which the Kootenay District was responsible to administer
and enforce.
The new function of processing applications for temporary approvals authorized by Legislature in 1972 resulted in 15 approvals being issued, mostly for asphalt

plants. Inspections were carried out on a regular basis to ensure compliance with
the terms and conditions of these approvals.
Considerable time was spent in establishing new District procedures in the
recordings of information as a result of the establishment of a data storage and
retrieval system for all discharge and receiving environment-monitoring data.
The special Elk River study, initiated in 1969 to determine the effect of coal-
resource developments on the Elk River, was continued and inventories of septic
tank pump-out and gravel-washing operations were carried out.
The Libby Reservoir Study, initiated in 1969, was continued with the addition
of two stations on the impoundment. More stations were proposed for the impoundment; however, the water level was not high enough for this purpose. The
impoundment study includes a method of assessment of the rate of algal growth.
The Kootenay Lake Study, initiated in 1970 to monitor effects of pollution on
the lake, was continued. One of the side benefits of this programme is the possible
detection of any changes in water quality resulting from the Libby Dam operation.
This study, like the Libby Reservoir programme, includes an assessment of the
level of eutrophication. This is being done by sampling, enumerating, and identifying lake plankton, using a radioactive tracer, and by comparing various physical
and chemical parameters.
Okanagan District
W. A. Kastelen, P.Eng., Manager
During 1972 the Okanagan District office administered the Pollution Control
Act, 1967 in the Regional Districts of Okanagan-Similkameen, Central Okanagan,
and Columbia-Shuswap.
During the course of 1972 the Okanagan District permanent staff were increased from seven to ten persons and at year-end consisted of a District Manager,
an Assistant District Manager, an Engineer, a Biologist, three Technicians, two
Engineering Assistants, and a Clerk-Stenographer. Two Engineering Aides are
being employed on a nonpermanent basis. Two summer students were also employed as temporary help to compile an unregistered air-emission inventory which
found 213 unregistered emissions compared to a total of 237 registered emissions
for the Okanagan District.
The special water-sampling programme in the Naramata watershed which was
instituted last year in co-operation with the Projects and Research Division was
completed this year and the Shuswap Lakes Drainage Basin water-quality monitoring programme (chemical and biological parameters) was continued. A study concerning disposal of septic-tank pumpage was initiated and completed during the
year and a study (Penticton Air study) to assess the contribution of teepee burners
to the air pollution problem in Penticton was instituted. The Lumby air study (to
assess teepee burner contribution) and a study to assess the dustfall to the Okanagan
Lake in connection with the Federal-Provincial Okanagan Study were continued.
A biological stream-sampling programme for the district was initiated and the- general water-quality monitoring programme that was instituted for the whole district
in 1971 was continued. General air pollution monitoring continued on a limited
basis.
In 1972, 23 new pollution control permits and four amendments to existing
pollution control permits were issued in the Okanagan District, for a total of 75
active permits. During this same period, 45 applications for permits or amendments to permits, each requiring field investigation and reports, were received by
 Y 132 B.C. WATER RESOURCES SERVICE
the Okanagan District office. Due to the recent addition of authority to issue
approvals under the Pollution Control Act, 1967, 17 applications for approvals were
received by the district office during the year and 11 approvals for discharge of
waste materials were issued. During the year, 34 orders were mailed or served in
the Okanagan District and three charges for discharging unlawfully were laid. Of
the orders served, 31 required application for permit, one was for increasing the
degree of treatment, and two were for immediately ceasing discharge and closing the
works to further discharge.
The district office commenced using the Computer Data Storage Retrieval
System for its pollution control sampling and monitoring programme and investigated 85 pollution complaints during the year. Numerous requests for information
were also received.
North District
M. K. Baillargeon, P.Eng., Manager
The North District is responsible for administration of the Pollution Control
Act, 1967 in the Regional Districts of Bulkley-Nechako, Fraser-Fort George, Kiti-
mat-Stikine, Peace River-Liard, Skeena A, along with the unorganized Stikine region in the northwest corner of the province.
The staff in the district was increased to 10 with the addition of two Technicians and two Engineering Assistants in 1972. During the summer, two Engineers
appointed for the Industrial Division were temporarily assigned to the North District for a period of five months.
The North District office moved to 3691—15th Avenue, Prince George, in
November. A field office was established in Fort St. John in 1972 to provide local
Pollution Control Branch service in the northeast portion of the Province.
Eighty-seven applications for permits and six applications for amendments
were received and 51 site investigations were submitted to the Processing Division.
Thirty new permits and six amendments were issued, bringing the total number of
permits in the North District to 109. One approval was granted under the new
amendments to the Pollution Control Act, 1967.
Minor revisions to the Upper Fraser River water-quality study were incorporated into the sampling schedule and the programme for 1972 completed as planned.
Biological study was limited to sampling and identification of benthic invertebrates
in some tributary streams. More intensive biological sampling is planned as equipment and personnel become available and programmes are established.
Programmes were initiated to evaluate the effect of existing discharges on the
Fraser River near Prince George, and the Peace River near Taylor.
Monitoring programmes to evaluate water quality in the Skeena River system
and Lakelse Lake were formulated by North District personnel and modification
to the programme suggested by Projects and Research Division were incorporated.
The field work for these programmes is sheduled to start in the spring of 1973.
Ambient air-monitoring programmes were initiated in the District of Mackenzie and the Village of Taylor. Two full and seven partial air stations were
established. The monitoring equipment is capable of measuring suspended particulates, dustfall, soiling index, and sulphation rate.
The North District provided information and assistance to applicants and
permittees, investigated many complaints, and responded to numerous inquiries
from the public for information.
 POLLUTION CONTROL BRANCH
Y 133
Lower Mainland District
W. G. Hamilton, P.Eng., Manager
The Lower Mainland District office is responsible for administration of the
Pollution Control Act, 1967 within the Regional Districts of Greater Vancouver,
Central Fraser Valley, Dewdney-AIouette, Fraser Cheam, Squamish-Lillooet, and
Sunshine Coast.
The duties performed by the district personnel include the administration of
pollution control permits, providing advice and information on pollution control
matters, investigating pollution in its many forms, following up on specific complaints, and establishing a general surface water-quality data bank.
The following statistics reflect the increased work load in this district:
1970 1971 1972
Effluent permits   112 121 137
Solid waste permits        1 4 13
Air emission permits                  5
Effluent applications     20 43 60
Solid waste applications       2 7 20
Air emission applications  3 7
Orders of the Director               42
The regular programme of inspection and sampling discharges under pollution
control permit within the Lower Mainland District continued on a quarterly basis.
A similar programme related to general surface-water quality on major streams,
lakes, and in marine waters of the Gulf of Georgia was continued. Major rivers
are sampled bimonthly, while lesser rivers and streams are sampled on a basis of
two, three, or four times per year, depending on the significance of discharges or
contamination factors. This water-quality programme comprises 108 sampling
stations with field measurement and laboratory analysis to determine up to 30 parameters.
Subsequent to the revised Government policy which extended the registration
date of effluent and solid-waste discharges to March 31, 1972, this office advised
nonregistered dischargers, that had been recorded on the 1971 inventory, of the
need to register, and transmitted necessary registration forms. An estimate of air
emissions (not registered) was undertaken with summer help in 1972 in all regional
districts except that of the Greater Vancouver Regional District.
Administration of the Pollution Control Act, 1967 with respect to air-pollution
control within the Greater Vancouver Regional District was transferred to that
authority in the spring of 1972 following enabling legislation. In conjunction with
this transfer of responsibilities, 14 ambient air-quality stations were relinquished
to the regional district to be included in their monitoring programmes.
The Lower Mainland District established three ambient air-quality stations in
Squamish to provide background information on dustfall, particulate material in
the air, soiling index, and measurement of certain sulphurous components. In addition, a mobile trailer containing more sophisticated air-quality and meteorological
devices was placed in Squamish and used extensively for staff-training purposes.
This facility will be producing data for record as of January 1973.
The district office staff was expanded to a total number of 10 in 1972. All
office space is now fully committed.
The district office has responded to numerous requests for assistance in interpreting registration and permit application requirements during the year.    Com-

plaints and reports related to discharges were handled on a routine basis, as were
meetings with municipalities, industries, small businesses, and the general public.
Coast District
J. W. Thomas, P.Eng., Manager
The Coast District office administers the Act in an area covering Vancouver
Island and the west coast of the Mainland from Powell River to Ocean Falls. Eight
regional districts are included in this part of the Province.
During the year a Pollution Control Branch field office was established in
Courtenay to meet the demands of the growing work loads in this northern part of
the district. Additions to the district staff include a Biologist, an Engineer, a Technician, and an Engineering Assistant, making a total staff of nine. Two summer
students were employed, for sampling, and skin-diving to check outfalls.
At the present time there are 112 permits issued in the Coast District, an
increase of 25 over 1971; 61 applications are currently being processed, and four
approvals were issued.
Inspection and sampling of discharges under permit continued during the year,
as well as background monitoring of rivers and lakes at 65 sampling locations. The
servicing of 13 air-monitoring stations is also carried out on a routine basis.
Sampling data are now becoming available from the computer programme which
was instituted during the year. During 1972, 339 investigations were carried out
by staff of the district.
Assistance to the Projects and Research Division was provided in the study of
a fire-fighting project on a wood-waste dump under permit. Preliminary work has
also been carried out on an interdepartmental study of Comox Harbour, which
involves a sampling programme to be carried out by the district office.
GENERAL OFFICE
Stephen J. Hives, Administrative Officer
Under general direction of the Administrative Officer, the staff now consists of
14 Stenographers, 12 Clerks, 2 Typists, and a Switchboard Operator to augment
and support the functions of the technical and professional staff of this Branch.
Growth of the Branch has been reflected in the increased demand for stenographic
and clerical assistance. For most efficient operation, the general office has. now
been separated into three sections—Secretarial Services, Expediting Services, and
Central Registry.
Secretarial Services are now headed by a Clerk-Stenographer 5 with three
stenographic pools placed through the main office, with service to divisions rather
than to individuals.
Under the supervision of the Senior Expeditor, clerical assistants have been
provided for each division, thus freeing technical and professional staff from routine
clerical duties and to ensure that statutory requirement of the Pollution Control Act,
1967 and regulations are met with.
With the completion of additional office quarters, Central Registry has been
expanded to a larger area. Originally this section was responsible for incoming and
outgoing mail, files, and records; however, a new function has now been added to
duties of Central Registry staff. Two staff members are now involved, through the
Projects and Research Division, in the organization of an Information Retrieval
System in conjunction with the Data Centre.    This will enable information with
 POLLUTION CONTROL BRANCH
Y 135
respect to permits and permit applications to be stored and retrieved where necessary. The second phase of this programme is now beginning with the feeding into
the data bank of permit conditions and parameters to supplement monitoring results
already stored.
In addition, a technical library is being assembled to provide technical references for professional staff. Because of the wealth of literature being produced in
the pollution control field, growth of this library is of significance in keeping abreast
of new technology.
  CHEMISTRY

  CHEMISTRY
LABORATORY
A. J. Lynch, B.Sc, M.P.H.
Chief Chemist
The Chemistry Laboratory performs chemical analyses of air, water, and land
contaminants. The routine analyses increased from 55,000 tests in 1971 to 92,000
tests in 1972, an over-all increase of 67 per cent. In addition to the routine work
load, a number of major projects was completed, new tests introduced, and increased
instrumentation services and field supplies provided to other branches and departments.
In 1972, analytical services were provided for
(1) Pollution Control Branch, Water Resources Services;
(2) Health Branch, Department of Health Services and Hospital Insurance;
(3) Canada (British Columbia Okanagan Basin Agreement);
(4) Water Investigations Branch, Water Resources Service;
(5) Fish and Wildlife Branch, Department of Recreation and Conservation;
(6) Department of Health Care and Epidemiology, University of British
Columbia;
(7) Water Rights Branch, Water Resources Service;
(8) Cities and municipalities.
The above agencies are listed in descending order of total work load submitted
in 1972.
The number of staff in the Chemistry Laboratory was increased during the year
from 32 to 52. The competitions resulted in nine staff members receiving promotions. The turnover rate was higher in 1972 than in 1971, and considerable difficulty was encountered in recruiting staff with experience in environmental chemistry.
The Data Processing Centre and the Chemistry Laboratory continued the study
of laboratory reporting procedures and automated data capture methods. Interim
changes in reporting procedures were introduced to increase efficiency and decrease
reporting time. Beginning in May, all laboratory reports were forwarded to the
Data Processing Centre for key-punching, completion of monthly laboratory management reports (LABMAN), and, when applicable, entry to the Pollution Control
Branch data bank. The output of LABMAN provides the following management
information:
(1) The number and types of samples submitted and tests performed for
each agency:
(2) The total work-load units utilized by each submitting agency:
(3) The number and types of tests performed by each laboratory section.
Planning for the installation of computer facilities in the Chemistry Laboratory
was also initiated.
In October a final report of an air-quality study in the Lower Mainland was
completed and released. This three-year study was initiated in 1968 prior to the
transfer of the Chemistry Laboratory from the Health Branch to the Water Re-

sources Service. A continuous air-monitoring station, a mobile air-quality laboratory, and 15 fixed air-sampling stations were designed, installed, and operated for
an 18-month period. The main objectives of the study were to determine the basic
air quality of the Lower Mainland and to determine if a diurnal change in wind
direction caused pollution produced in the Lower Mainland to return to the same
area. The report is entitled "Lower Mainland Air Quality Study Final Report."
Renovations of a basement area in the B.C. Research Building were completed in September. This additional laboratory area provided space for the following sections: Field Services, Instrumentation Services, Autoanalyzer (nutrient analyses), and General Services (BOD analyses).
The Chemistry Laboratory participated in round-robin quality-control studies
sponsored by Environment Canada and the U.S. Environmental Protection Agency.
In all cases the Chemistry Laboratory results compared well to the supplied
standards.
Water Quality Division
Mrs. I. Kalnins, Head of Division
The Water Quality Division provided analytical services to a number of Governmental departments for water and waste-water analyses. Analytical services
were also provided to the Canada-British Columbia Okanagan Basin Study, which
involved the analyses of samples from landfills, lyshneter tanks, spray irrigation
system, wells, and lime pilot plant studies. In 1972, a total of 83,000 water chemistry tests were performed. This represents an increase of 60 per cent over 1971.
During the year, changes were made in the organizational structure of the
Water Quality Division. Two sections were formed from the existing Spectrophoto-
metric Section—the Autoanalyzer (automated analyses) and the Manual Colori-
metric Sections. A Quality Control Section was also established. The Water Quality
Division now consists of the following sections—General Services, Manual Colori-
metric, Atomic Absorption, Autoanalyzer, and Quality Control. The reorganization
resulted in the establishment of two new supervisory laboratory scientist positions.
The major equipment purchased in 1972 in the Water Quality Division was a
graphite furnace with deuterium background corrector for increased sensitivity of
metal analyses, a mercury monitor, additional autoanalyzer units for nutrient analyses, refrigerator incubators for BOD analyses, and a gas chromatograph for the
analyses of organic contaminants.
Projects completed during 1972 are included in the following:
(1) Automation of silica, chloride, sodium, and potassium analyses:
(2) Evaluation and introduction of procedures for total mercury analyses:
(3) Evaluation of the Stannous -Chloride Method versus the Ascorbic
Acid Method for phosphorous determination of industrial effluents;
this resulted in the adoption of the Ascorbic Acid Method:
(4) The addition of aluminum, barium, silver, and vanadium to the
routine tests presently performed by the laboratory:
(5) Modification of reporting procedures:
(6) Participation in the time studies of analytical and clerical operations
conducted by the Systems and Programming Division of the Data
Processing Centre.
Projects currently in progress are as follows:
(1) Comparison of BOD results using sewage seed versus acclimatized
seed for industrial waste samples:
(2) Compilation of a methods manual of Chemistry Laboratory methods
for water and waste-water analyses.

H. See, Head of Division
The Air Quality Division of the Chemistry Laboratory continues to provide
analytical services to the Pollution Control Branch for the air-monitoring stations
operated throughout the Province. The number of the air-monitoring stations increased from 62 in 1971 to 107 in 1972. Air samples were received from the
following areas: Victoria, Langford, Lake Cowichan, Powell River, Trail, Castlegar,
Kimberley, Natal, Sparwood, Creston, Vancouver, Delta, White Rock, Squamish,
Mackenzie, Terrace, Taylor, Williams Lake, Kamloops, Quesnel, Penticton, and
Lumby. In addition, the Air Quality Division also provided analytical services to
the University of British Columbia, Department of Health Care and Epidemiology.
This project was supported by a National Health Research Grant.
The work load of the Air Quality Division increased from 342 tests per month
serving 62 stations in January to 649 tests per month serving 107 stations in December, an increase in work load of 88 per cent.
In addition to the routine tests, progress was made on the following projects:
(1) Introduction of methods for the determination of fluoride and sulphate in vegetation samples:
(2) Introduction of methods for the determination of oxides of nitrogen,
and free chlorine in the atmosphere:
(3) Introduction of methods for the determination of particulates, sulphur dioxide, and ethyl alcohol in stack samples:
(4) Development of additional methods for microscopic measurements
of particle size and distribution:
(5) Investigation of the sulphation plate method for the determination of
sulphation index.
Field Services Section
D. Sandberg, Head of Section
The Chemical Field Services Section was established in the Chemistry Laboratory to provide a liaison between laboratory and field staff. New procedures have
been introduced to improve the flow of samples into the laboratory. In 1972, 6,000
water and 1,300 air samples were received, logged, and transferred to the analyses
sections; and approximately 600 shipments of chemicals and supplies were made to
field offices.
To accommodate the work-load increase, this section implemented the following:
(1) Standardized submission and preservation procedures were established for water samples:
(2) In conjunction with the Data Processing Centre, a system of flowsheets were designed to speed sample information to analysts in the
laboratory:
(3) A sample-handling area in the laboratory was designed and constructed to facilitate sample entry and to supply shipment to the field:
(4) A tour of Pollution Control Branch district offices and a number of
orientation lectures were carried out to describe standard laboratory
procedures to field staff.

W. R. Meighen, P.Eng.
Inspector of Dykes
In the spring, the Hydrology Division of the Department reported that the
winter snow-pack was very heavy, and that above-average spring freshets were expected to occur in the major rivers of the Province.
Valley dyked areas were given warning that a larger-than-usual potential flood
threat existed. Municipalities and dyking districts in these valley areas were advised
to carry out some preparatory planning for coping with a disastrous high-water condition, should it occur.
In the Fraser Valley, Fraser River levels rose above the 20-foot reading on the
Mission gauge on May 31 and remained continuously above this level for 27 days,
this time period only being exceeded twice previously in this century—in 1948 when
the river remained above 20 feet for 32 days and in 1967 when it remained above
20 feet for 29 days.
The peak level registered on the Mission gauge was 23.34 feet on June 17,
and this peak level has also only been exceeded twice previously in this century—
in 1948 when the highest reading was 24.71 feet and in 1950 when a peak level
of 24.19 was recorded.
All dykes were patrolled during the height of the freshet and minor problems
occurred in some areas, which necessitated some relatively small amount of emergency work. All dyking systems in the Fraser Valley withstood the freshet successfully and no failures or disasters occurred.
Because of the duration of the freshet period, a considerable acreage of land
in lowest parts of many dyked areas suffered flood damage from seepage waters.
A very heavy rainfall in the early part of July while the river was still at moderately
high levels caused flooding of some additional land areas.
The Dewdney Dyking District, a development district constituted under the
Drainage, Dyking, and Development Act and administered by the Inspector of Dykes,
and the South Dewdjney Dyking District, an improvement district under the Water
Act and administered by Trustees, were dissolved at year's end, and a new improvement district to amalgamate and replace them was constituted under the name of the
Dewdney Area Improvement District. The new district will be administered by
Trustees.
The eastern portion of the Sumas Drainage, Dyking, and Development District
was dissolved from the dyking district and transferred to the Township of Chilliwhack as a specified area under the Municipal Act, also at year's end.

OKANAGAN
LANDS
PROJECT
W. J. Stephenson
Supervisor
The Southern Okanagan Lands Project (SOLP) is administered under the
jurisdiction of the Water Resources Service. The area under this administration
comprises approximately 22,000 acres of land purchased by the British Columbia
Legislature under the Soldiers' Land Act in 1919. Although it is estimated that
8,000 acres of this land are irrigable, the existing irrigation system serves only 5,500
acres, of which 4,900 acres receive pressurized irrigation water. The operation
and maintenance of this irrigation system continues to be the major responsibility of
the SOLP.
In 1964 the Southern Okanagan Lands Irrigation District was formed as an
improvement district incorporated under the Water Act. It is responsible for the
operation of a domestic-water system which is an integral part of the irrigation works,
and, when the rehabilitation programme has been completed, will also administer the
irrigation system. A rehabilitation programme for the irrigation system was commenced in 1964 under the Agricultural Rehabilitation and Development (British
Columbia) Act. The gravity part of this new system consists of approximately 13
miles of concrete canal, including 16 metal flumes on concrete, steel, or timber
trestles, and 3,600 feet of 78-inch-diameter siphon. From this gravity system and
from Osoyoos Lake and numerous wells, water is pumped to orchards and. residences. The combined pumping capacity of the pressurized system is approximately
45,000 gallons per minute (100 cf.s).
Operation
A record high winter snowfall combined with heavy spring rains resulted in
a heavy spring run-off in the Okanagan Valley in 1972. Okanagan River flood-
channel flows were maintained at a high level until the end of August to accommodate this run-off. Flooding occurred at Tugilnuit Lake and Osoyoos Lake, with the
latter reaching water levels above those recorded in 1948. Tugilnuit Lake flooding
was relieved with the installation of a temporary pump which discharged the flood
waters into the adjacent river channel. SOLP crews undertook responsibility for the
operation and maintenance of this diesel-fueled unit until the flood threat had subsided. Severe winter weather also probably contributed to several rockfalls that
damaged Flume 1 prior to the start of the irrigation season. Damage to the flume
proper was minimal due to the effectiveness of the protective roofing. However,
some difficulty was experienced in repairing the badly damaged roof because of
constant danger from falling rocks.
151
 Y 152 B.C. WATER RESOURCES SERVICE
The irrigation season commenced officially on May 4, and terminated on
October 4. Weather conditions during the summer were considered normal except
for a particularly long dry spell in July and August. Operation of the irrigation
system was uneventful with water demands being met on all pumping-systems except
Nos. 1 and 4 where some low pressures were experienced. Distribution of flow-
control valves to these latter systems was delayed by supply problems. It is expected
that the 1973 irrigation season will see the completion of this distribution programme and an opportunity to assess its effectiveness. As a result of unseasonably
cold weather, irrigation water was requested for frost protection by vineyard owners
during the first half of October. The irrigation season was also extended for a
number of orchardists in the Osoyoos area where soils showed exceptional dryness
in mid-October.
Satisfactory operation of the new irrigation system was marred by the failure of
Flume 12 a few days prior to the end of the irrigation season. Extensive damage to
property occurred as a deluge of water and sand inundated orchards and a home.
Work is presently under way to replace the collapsed flume with a section of concrete
canal supported on a compacted embankment fill. Total cost of the clean-up, property damage, and loss claims and reconstruction is estimated to be $35,000.
Ditchriding service was extended to the Black Sage Irrigation District at their
request.
The annual revenue of the project to December 8, 1972, is as follows:

of which were temporarily vacant. In addition there were 68 temporary employees
on staff.
The following table summarizes the activity in the Personnel Office in 1972. As
can be seen, continuous staff recruitment reached an all-time high, with a 68-percent increase over 1971, and a 272-per-cent increase over 1970. Recruitment of
short-term employees also increased by 36 per cent over 1971. On the surface,
there appears to be a startling increase in turnover; however, analysis of this increase
indicates that turnover has returned to the pre-1970 level after a pleasant two-year
decrease. Our turnover in 1972 averaged 12.5 per cent, still significantly lower than
the Government-wide average of 14.3 per cent in 1971. Professional staff turnover
was 7.3 per cent, technical staff 11.7 per cent, clerical staff 24.8 per cent, and
operational services staff 8.3 per cent. A disturbing rate of turnover did, however,
occur in the technical staff employed in the Chemistry Laboratory, where the rate
reached 38 per cent. A large increase (214 per cent) in Departmental promotions
occurred in 1972, primarily due to the Pollution Control Branch reorganization that
was a result of their staff increase. Reclassification was the only area where activity
decreased. Forty reclassifications were processed and, although this represents a 27-
per-cent decrease over 1971, which was a record year, we still ran 90 per cent over
1970.

Recruiting of most pollution control engineering disciplines eased in 1972;
however, difficulty was still experienced in acquiring air engineers. Difficulty was
also experienced in hiring biologists and laboratory scientists and technicians experienced in pollution analysis techniques. In April, a recruiting team visited the
Universities of British Columbia, Calgary, Alberta, Saskatchewan, and Manitoba to
recruit engineers for the Pollution Control Branch. Experienced engineers were
also interviewed at these locations.   A great deal of assistance in recruiting engineers

 Y 156 B.C. WATER RESOURCES SERVICE
for the Pollution Control Branch was given to the Water Resources Service by the
Civil Service Commission, and the Departmental Personnel Office would like to
thank them sincerely for this much needed help.
The sick-leave rate for the Service in 1972 average 4.3 days per employee,
which compares to our 1971 average of 4.2 days per employee. The Government-
wide average was 6.2 days per year in 1971, which is significantly higher than the
Water Resources Service.
A British Columbia Safety Council bronze award of merit was presented to the
Water Rights Branch in 1972, after 137,746 man-hours without a time-loss accident.
In October, the Departmental Personnel Officer visited the nine Water Resources Service offices in Cranbrook, Nelson, Oliver, Penticton, Kelowna, Vernon,
and Kamloops, where he discussed personnel problems and procedures and met
many staff members for the first time.
Educational programmes conducted in the Water Resources Service in 1972
included a Civil Service Commission short course in supervision, given to Section
Heads and Division Chiefs of the Pollution Control Branch, and a Civil Service Commission correspondence course in supervision for Pollution Control Branch District
Managers and their assistants. A two-day workshop and laboratory tour was also
conducted by the Pollution Control Branch at the Chemistry Laboratory in Vancouver.
This year, a defensive driving course has been made available to all Government
employees whose work involves a significant amount of driving. The course is being
conducted by the Accident Prevention Division of the Civil Service Commission, and
to date 13 Water Resources Service personnel have successfully completed it. At
the year-end, courses were being set up and conducted throughout the Province so
that district staff could also take advantage of this opportunity.
Annual meetings were held by the Water Rights Branch District Engineers and
the Pollution Control Branch District Managers, which the Personnel Officer attended for discussions concerning personnel procedures.
Four employees of the Service are at present attending the Executive Development Training Plan. They are K. N. Pleasance, Engineer, Water Investigations
Branch (third year); S. J. Hives, Administrative Officer, Pollution Control Branch
(second year); G. G. Soellner, Technician, Pollution Control Branch, and J. H.
Morley, Engineer, Water Investigations Branch (first year). Mrs. G. M. MacNutt,
Clerk, Pollution Control Branch, graduated from the Correspondence Course in
Public Administration in 1972, while G. A. Poole, Clerk, Pollution Control Branch,
is at present taking this course.
Retirements of three long-service employees occurred in 1972. They were
H. L. S. Hammersley, Engineer, Water Investigations Branch, after 23 years of
service; J. C. Young, Ditchrider, Southern Okanagan Lands Project, after 28 years
of service; and Mrs. N. R. Morton, Clerk-Stenographer, Water Rights Branch, after
11 years of service.
During the year, two Water Resources Service employees died accidentally
while in service. They were J. W. Ferguson, Technician Pollution Control Branch,
Nelson, after four-and-one-half years' service, and Mrs. Jean Bolton, Laboratory
Assistant, Chemistry Laboratory, Vancouver, after four months' service.
Water Resources Service employees who received 25 years continuous service
certificates in 1972 were as follows:
J. T. Gulliver, Technician, Water Investigations Branch;
T. A. J. Leach, Assistant Chief Engineer, Water Investigations Branch;
Miss S. R. Mitchell, Secretary to the Deputy Minister of Water Resources; and
R. J. Parker, Mechanic, Southern Okanagan Lands Project.

  ACCOUNTING
DIVISION
M. B. Maclean
Departmental Comptroller
As indicated in the previous Annual Report, the workload of the Accounting
Division was continuing to increase with the general expansion of the Department
as a whole, and as a result we have been able to increase our permanent establishment by two—one in the accounts payable section and the other in the water rentals
section.
During the latter part of the past year the Division was assigned the task of
processing some 3,000 flood claims, which necessitated full-time employment of a
senior staff member and subsequent realignment of duties of other staff members.
The data processing system, installed in 1971 to produce statistical and accounting information for water licences and rentals, has worked extremely well, with
some 11 programmes providing a wide variety of useful information and an easily
interpreted accounting record. One of the convenient features of the system is that
a wide range of rental changes may be made by computer calculation, thus eliminating the previous tedious manual method.
