By March, 1967, the measurements of the snow cover throughout the major
river basins in the Province indicated a heavier than normal snow pack for that time
of the year. In view of this threat, the Water Resources Service advised all
responsible authorities of the impending conditions, and preparations were made
with other departments and with local authorities to meet severe flooding conditions.
Concurrent with these developments, arrangements were made with appropriate
agencies for the operation of major reservoirs on the Fraser River and Columbia
River systems to accommodate some portion of the run-off and thus lower downstream water levels. This latter measure provided reductions at critical points on
both river systems and was considered successful within the capability of the
available storage.
Very fortunately, near ideal weather conditions developed and dangerously
high water levels did not occur, although localized areas, such as Trail, did experience some flooding. Emergency organizations planned for the Lower Fraser Valley
and the Kootenay-Creston area did not have cause to function. In anticipation of
severe high river levels, a considerable amount of preparatory work was carried out,
especially in the dyked areas of the Lower Fraser Valley and on the Kootenay Flats,
and during the run-off period localized flooding and bank erosion warranted emergency work. Under interdepartmental arrangements, a total of $1,150,000 was
expended in the preparations to combat the flood water levels and for repairs to road
and river-bank damage.
In contrast, the summer brought very dry conditions, especially to the Southern
Interior, and water supplies for the irrigation systems were severely taxed. Okanagan Lake levels were maintained close to the minimum only by severely restricting
the outflows at the regulating dam near Penticton. This water shortage renewed
public interest in the possibilities of a diversion of Shuswap River waters southward into the Okanagan system, a proposal which has been under study by the
Water Investigations Branch for some time.
The Water Investigations Branch is associated with an increasing number of
water projects which receive Federal-Provincial assistance either under the Agricultural and Rural Development Act or the Canada-British Columbia Joint Development Act and the Canada Water Conservation Assistance Act. A total of 44
projects, estimated to cost in the order of $22,000,000, has been approved under
the ARDA programme, and three projects totalling $4,000,000 have been cleared
under the Canada Water Conservation Assistance Act scheme. Engineering or
inspection services were provided by the Branch for current projects during 1967.
The Water Rights Branch experienced an active year. The spring flood threat
followed by the driest summer for many years resulted in heavy demands upon
the district offices. Water applications continued to climb, reaching just under
1,400 for 1967, and licences issued totalled 1,734, a modest increase over 1966,
and just under the 10-year average of IVz per cent per annum. Seven new improvement districts were formed during the year, bringing the total to 328, to reflect the
public growth and interest in local management. Further evidence of this is found
in the record of $5,219,000 in debentures issued by the improvement districts in
1967, which received Provincial Government guarantee.
Electrical-energy generation in 1966, the last year for which data are available,
had reached a total of 20,881,000,000 kilowatt-hours, of which 17,043,000,000
were produced by hydro-electric installations. This latter represents an increase
of 11.7 per cent over the preceding year, whereas thermal generation increased by
12.9 per cent. Although, through interconnection, a relatively small amount of
energy was exported in 1966, the trend over the last few years has been toward
importing electrical energy to help meet Provincial demand. This trend was
continued in 1967, when the net import of energy amounted to 1,000,000 kilowatt-
hours to assist in meeting a load estimated to have been about 22,500,000,000
kilowatt-hours. New hydro-electric capacity in 1967 helped meet the increasing
demand. The Aluminum Company of Canada placed in service the eighth unit at
Kemano, and Cominco commenced work on a fourth unit at its Brilliant plant on
the Kootenay River.
During 1967 some 11,380,000 cubic yards of material were placed on the
Portage Mountain Dam, topping out this mammoth structure and terminating a
three-year building programme. On September 12, 1967, the dam was dedicated by
the Honourable George Randolph Pearkes, VC, P.C, C.C, C.B., D.S.O., M.C,
CD., Lieutenant-Governor of British Columbia, and named W. A. C. Bennett Dam
to honour the Premier of British Columbia. Power from this project is scheduled
for transmission in 1968.
Construction of the Columbia River Treaty dams is progressing favourably,
with the Duncan Lake storage dam being completed in mid-1967, approximately
one year ahead of schedule. On August 17th Premier W. A. C. Bennett officially
dedicated this project, following a successful filling period when the reservoir served
to provide a degree of flood control for Kootenay Lake and the City of Trail.
A new Pollution Control Act in 1967 divorced the Pollution Control Board
from the daily administration of the Act, placing this responsibility with the Director
of Pollution Control. Provision was made in the new Act for Board action in
respect to air pollution and abatement. A report from the Chairman of the Pollution
Control Board is enclosed with the annual report of the Pollution Control Branch.
The Annual Report of the Water Rights Branch for 1951 made mention of
the committees and sub-committees functioning to lay plans for the development
of the Columbia River and its tributaries in British Columbia and south of the
International Border. This teamwork was to lead Branch engineers through a
multitude of proposals with their Canadian and American counterparts before a
solution acceptable to all formed the basis of the Columbia River Treaty and
Duncan Lake dam, first of the Treaty projects, was completed in 1967, and
the flood waters of May and June were used to fill the new lake which now occupies
the valley behind the dam. Reference to this project and a brief review of the
progress being made on the Arrow Lakes dam and at the Mica Creek dam-site will
be found in the Comptroller of Water Rights' report, which follows. At this stage
of major development, it would seem appropriate to look back over the years to
some of the earlier activities associated with the Columbia and Kootenay Rivers
as we know them in British Columbia.
Chronicles of 1866 record the exploratory surveys on the Columbia and
Kootenay Rivers. Those explorations were primarily to seek access across the
Columbia Mountains in order to tie the rich valley of the Columbia River securely
to the seat of administration in New Westminster. The early surveyors, however,
had been preceded by men seeking gold, and even by then camps and landings had
been established with names which remain to this day. One of the most active
areas was in the vicinity of what is now known as Goldstream River, a stream
which enters the Columbia Valley some 50 miles north of Revelstoke. In 1866
Mr. W. Moberly, acting on instructions of the Chief Commissioner of Lands and
Works, " to repair to Seymour by the first opportunity, for the purpose of resuming
the duties of exploration and construction of trails in the Columbia River District . . .," spent the best part of that summer with several small parties, travelling
extensively over little-used trails and unexplored country, seeking potential routes
through the mountains. He entered the Columbia River valley by way of the
North Arm of Shuswap Lake, crossing the divide at the head of Ratchford Creek,
then descending into the Columbia River valley near Kirby's Landing, believed to
be in the vicinity of the mouth of Downie Creek.
In succeeding months of that year, Mr. Moberly travelled southward down the
Columbia River and Arrow Lakes, thence eastward by horse trail, crossing the flats
at the south end of Kootenay Lake, where he spent one full day seeking the best
route through this low marshy area before continuing eastward to Wild Horse Creek
on the Kootenay River. Northward on his circuitous journey, Mr. Moberly crossed
yet another broad flat river bottom of later significance. This was the short divide
between the Kootenay River and Columbia Lake, an area subsequently to go by the
names of McGillervray's, Portage, and then Canal Flats. By horse and then by
canoe he travelled down the Columbia River to Boat Encampment, a spot Mr.
Moberly considered likely to become a settlement of some importance, and then
southward to his original point of departure at Kirby's Landing.
Although Mr. Moberly did not record any impression of the agricultural potential of the Kootenay Flats, less than 20 years later a Mr. Baillie-Grohman saw the
possibilities of that area and proposed a reclamation scheme for the lands between
the south end of Kootenay Lake and the International Boundary. His initial plan
was a scheme to dyke much of the area, and at the same time increase the outflow
of Kootenay Lake by widening Grohman Narrows and thereby lowering water levels
during the flood period of the year. This latter proposal he abandoned in favour
of a diversion scheme to carry the flood flows of the Kootenay River system directly
into the Columbia River, by-passing Kootenay Lake. This plan envisaged a canal
on that flat crossed by Moberly in the summer of 1866 when the latter rode northward up the Kootenay Valley and so into the Columbia Valley at Columbia Lake.
By 1885 Mr. Baillie-Grohman had received permission to construct a canal between
the two river systems, subject to approval by the Dominion Government. Despite
considerable objections filed in Ottawa, Mr. Baillie-Grohman received a permit from
the Dominion Department of Public Works to construct a navigation channel with
the stipulation that it include lock-gates that were to be kept closed after August
30th each year except for the passage of boats. The canal was built, but records
indicate that only two boats used the passage. It was a failure in its prime reason
for construction, probably because of a lack of basic information on the flows it
should have been capable of accommodating. Some years later the scheme was
abandoned and the canal silted up, although not sufficiently to prevent a diversion
of a portion of the 1948 flood waters from the Kootenay into Columbia Lake. In
the meantime Mr. Baillie-Grohman had turned his attention to the reclaiming of the
land at the Kootenay Flats after his canal had been completed in 1889. Difficulties
with finances and internal disputes with the company for which he acted as general
manager subsequently led to his withdrawal from the plan. Construction of a system of dykes was started by another company in 1893, but these, like others in the
Province, were severely damaged during the extreme floods of 1894. The dykes
were rebuilt, and in due course became the responsibility of dyking districts operating as improvement districts under the Water Act, a status they have now held for
some years. Where Mr. Moberly crossed in 1866 and Mr. Baillie-Grohman planned
to dyke, there are now some 20,000 acres of valuable agricultural land protected
by 55 miles of dyking.
While agricultural development in the Kootenay Valley was struggling to show
some gain, the need for inexpensive electric power grew with the construction of the
smelter at Trail in 1895. By 1898 hydro-electric power from the first of several
plants was being delivered to the mines at Rossland, 32 miles away. This first plant
at Lower Bonnington Falls was one of several to be built which still utilize the outflows from Kootenay Lake to produce electrical energy not only for the mining industry, but also for the domestic needs of the towns in this part of British Columbia.
Increasing demand for power over the years led the Consolidated Mining and Smelting Company, owners of most of the hydro-electric plants built downstream from
Kootenay Lake in later years, to start construction of a large plant at Waneta, the
first choice of two possible sites on the Pend d'Oreille River in 1954. By 1967
hydro-electric power plants had been built with a total installed capacity of nearly
700,000 kilowatts.
Some years earlier Canadian and American interests had turned to look at the
Columbia River both in respect to its annual flood threat to Canadian and American
communities and in terms of its hydro-electric power potential. The Province of
British Columbia soon after became actively engaged in a multitude of assessments
of the potential of the Columbia and Kootenay Rivers in co-operation with their
Canadian and United States counterparts.
The Boundary Waters Treaty had been signed in 1909 by Canada and the
United States of America as a direct result of negotiations in respect to the Niagara
River diversion. The International Joint Commission was created by the Boundary
Waters Treaty, and over the past half-century all boundary waters problems have
been resolved following upon the deliberations of the permanent tribunal of Canadians and Americans, equally represented. An instrument of the International Joint
Commission is the Kootenay Lake Board of Control. This agency now regulates
the levels on Kootenay Lake somewhat as Mr. Baillie-Grohman visualized but
through the controls set up at Corra Linn, the first hydro-electric power plant dam
downstream from Mr. Baillie-Grohman's proposed section for widening.
Joint Canadian-American teams retraced Mr. Moberly's steps along the Columbia River from Columbia Lake, through Boat Encampment, past Kirby's Landing,
down to and across the border where Fort Shepherd once stood, and into the State
of Idaho, seeking the best solution for the development of this great river and its
tributary, the Kootenay. The prime potential of this river system is hydro-electric
power, but the greatest need is flood control. On the Columbia River the principal
area requiring protection against inundation lies along the main stem downstream
from The Dalles in Oregon, whereas on the Kootenay River such protection is vital
for the valley bottom between Bonners Ferry and Kootenay Lake. A number of
development schemes were enunciated by the agencies, and huge dams were visualized both on the Kootenay River and on the Columbia River in British Columbia.
Concurrent with the engineering studies were early negotiations between Canada,
British Columbia, and the United States on the effects of regulating these streams,
the benefits to be derived, and the division of these gains between the two countries.
In 1959, after over 10 years of study and assessment, a report compiled by the
International Columbia River Engineering Board was presented to the International
Joint Commission. This Board, comprised of representatives from British Columbia, Canada, and the United States of America, had reviewed a considerable number
of possibilities for river development, and in its report it detailed, amongst others,
three primary schemes embracing dams on the Columbia River in British Columbia
and on the Kootenay River both in British Columbia and in Idaho and Montana.
Any one of these proposals would be capable of providing what was considered to
be an essential flood storage of 8,450,000 acre-feet effective at the International
Boundary, and would produce an average of more than 16,000,000 kilowatts of
hydro-electric power.
The 18th and final conclusion appearing in the Engineering Board report noted
that " orderly development of the water resources of a basin normally requires that
the most economically attractive projects be constructed first; this process cannot
be followed completely in the case of the Columbia River basin unless co-operative
development is made possible by international agreement."
It is noted earlier in the conclusions that " some measures of general agreement
between the two countries should be reached with respect to principles for sharing
benefits and costs."
Following upon the submission of this report, the Governments of Canada
and the United States of America appointed teams to negotiate these aspects of
benefit and cost-sharing, and to draft a treaty. One year later the Columbia River
Treaty was signed by President Eisenhower and by Prime Minister Diefenbaker,
but final ratification on the part of the Government of Canada did not come until
1964 after a delay of some three years. The culmination of years of negotiation
was reached on September 16, 1964, when President Johnson and Prime Minister
Pearson attended a ceremony at the Peace Arch near Blaine, Washington, to ratify
publicly the Columbia River Treaty. Throughout the long years of study and
negotiations, the Water Rights Branch participated in all aspects of planning and
negotiation, representing British Columbia at the multitude of meetings and technical
liaisons. The Water Resources Service continues to be associated with the developments on the river through the Deputy Minister, who was appointed to a position
on the Permanent Engineering Board, Columbia River Treaty in 1964.
The Columbia River Treaty and Protocol set the stage for the Treaty dams
to be constructed in British Columbia and in Montana. Where Mr. Moberly
travelled 100 years ago, the huge Mica Creek dam on the Columbia River is rising
today, only a few miles upstream from Kirby's Landing and the goldfields of that
time on the Goldstream River, while southward the smaller Arrow Lakes dam is
well along in its construction phase. Mr. Moberly in 1866 had dispatched a Mr.
Turnbull to explore the possibilities of a wagon route between the north end of
Kootenay Lake and the upper Columbia River valley. Mr. Turnbull proceeded up
the Columbia River from Fort Shepherd, thence up the Kootenay River, portaging
around the sites where the West Kootenay Power & Light Company was to build
hydro-electric plants some 30 years later, entered Kootenay Lake, and journeyed
northward into upper Kootenay Lake to reach the foot of Kinbasket's trail. Today,
in the area where Mr. Turnbull cached supplies for his explorations on foot eastward
over the Purcell Mountains, there stands the Duncan Lake dam, completed in 1967,
to be the first of the Treaty dams constructed in British Columbia. When, on
August 17th, the Honourable Prime Minister, Mr. W. A. C. Bennett, sent the control
gates clanging shut to close off the Duncan River, there began a routine of annually
storing the spring flood run-off from that tributary of the Kootenay River. Storage
behind Duncan Lake dam will provide a measure of flood control not only for
Kootenay Lake, but also for the downstream lowlands of the Columbia River, and
at the same time will regulate stream flows in some degree for the benefit of the
hydro-electric power-producing plants in the United States.
With Duncan Lake dam completed, as may be seen on the cover of this Report,
with Arrow Lakes dam well under way, and with the great Mica dam just started,
the proposals of the International Joint Commission are being developed to the
benefit of both countries. When completed, the Mica project will be capable of
generating power from an installation of 1,820,000 kilowatts and will provide some
flood control on the main stem of the river. Arrow Lakes project and the completed
Duncan dam will act solely as water-storing reservoirs for downstream benefits.
South of the border, the first contracts have already been let for the construction
of the Libby Dam on the Kootenay River, a major option in the terms of the
Columbia River Treaty which has been taken up by the Government of the United
States of America.
One hundred years ago a representative of the Chief Commissioner of Lands
and Works for the Crown Colony of British Columbia was seeking wagon routes
between the Columbia River valley and points west. Today roads loop through
the mountains, and the Columbia River and its tributaries are being controlled
through a far-reaching plan which will harness the power of these rivers and provide
protection against flooding to the downstream lowlands under a unique international
agreement brought about through co-operation and goodwill on the part of all those
whose task it was to create this mammoth scheme.
A very heavy snow pack in British Columbia accumulated during the late
winter and early spring of 1966/67, and the assessment of the flood potential of this
snow mass is discussed in the Water Investigations Branch section of this Report.
On the basis of the information available from the March and April snow
measurements, preliminary steps were taken to prepare against a possible major
flood condition in the Province. Principal area of concern was the Lower Fraser
Valley, and early contact was made with all municipal officials in that region. Close
liaison was also established with the Department of Highways, and a joint organization was planned which would have functioned in the Lower Fraser Valley if conditions there had exceeded the capabilities of dyking districts and municipalities to
control. As time progressed, this organizational plan was further developed by the
inclusion of Civil Defence, which in part was setting up a parallel plan to handle
evacuation of flood-threatened areas in the Lower Fraser Valley if such should have
occurred. The many interests of the Federal Government in this particular area
brought the Canada Emergency Measures Organization into the picture under the
direction of Regional Director (B.C.), who alerted an extensive organization which
made preparations in accordance with its respective interests. The closest liaison
was maintained between the Deputy Minister's office and Military Headquarters,
B.C. District, Vancouver, where the District Officer Commanding and his staff were
well prepared to supply men and equipment had such assistance been requested by
British Columbia.
The extensive organization set out on paper for the Lower Fraser Valley was
duplicated on a much-reduced scale for the dyked area of Kootenay Valley near
Creston. For both organizations, key supervisory positions would have been filled
at the critical time by engineers of the Department jointly with personnel of the
Department of Highways.
In anticipation of dangerous high-water conditions, emergency work was
commenced in a number of areas in the Province where it was considered that
such preventive measures would be advantageous. A programme of surface gravelling of the crown and strengthening known weak sections of dykes in the Lower
Fraser Valley and in the Kootenay Valley was initiated, using funds made available
for the purpose from Consolidated Revenue Fund and with local participation toward
the cost under certain circumstances. This work was completed before the rivers
reached their peaks. Elsewhere in the Province a limited amount of preliminary
work was carried out under the direction of Departmental engineers, largely on
stream-bank stabilization. The projects completed and costs are shown in Table I,
and further details appear in the report of the Inspector of Dykes.
During the critical period of snow-melt, the daily temperatures over the major
river systems varied between warm and cool, and these conditions were virtually
ideal for the melting of one of the heaviest snow packs on record. In consequence,
although river levels at vital points were high, there was no major damage and
preventive measures served to mitigate localized flooding.
For the first time in British Columbia, there was an opportunity to utilize
upstream storage on major rivers to effect some reduction in downtsream flood
levels. The Department maintained a close liaison with the British Columbia
Hydro and Power Authority and the Aluminum Company of Canada for the
operation of the storage reservoirs of the Authority on the Bridge River and the
Alcan reservoir on the Nechako River. The operation of these reservoirs to obtain
the best filling rates under the existing conditions resulted in a calculated reduction
of some 9 per cent on the peak discharge at Hope, bringing it down to approximately
383,000 c.f.s., a peak flow exceeded six times since 1894. This effect was continued
into the Lower Fraser Valley and resulted in a maximum water level at Mission of
about 22.7 feet, a figure also exceeded six times since 1894.
Storage of flood run-off in Duncan reservoir was undertaken in conjunction
with the trial filling programme designed to test the new dam. The storing proved
successful, reducing Kootenay Lake's peak level by about 1.9 feet and improving
water levels at Trail downstream on the Columbia River by as much as 1 foot.
In addition to the pre-high-water activities supervised by the Water Resources
Service engineers in the Lower Fraser Valley and in other areas, there was a considerable amount of protective work and emergency repair required on many streams
throughout the Province. Under the interdepartmental arrangement with the Department of Highways, staff and facilities of that Department met these emergencies.
The cost of stream-clearing, bank protection, general repairs, and washouts appears
in Table I.
The snow cover in the spring of 1967 was in amount sufficient to justify the
flood-hazard warnings which were issued with the snow bulletins. The fortunate
sequence of temperature variations over the major contributing areas during the
critical melt period, coupled with the upstream storing programme in the available
reservoirs, resulted in river levels which did not severely tax the downstream protective works. Suffice to say that the capabilities of the existing storage reservoirs
were fully extended, whereas those of the weather were not. A protracted warming
period instead of the intermittent cooling experienced would have produced dangerously high water levels in all rivers.

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 right of the Province.   The common-law principle of riparian water right has been abolished.
(2) 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.
(3) 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.
(4) 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.
(5) If it is necessary that a water licensee construct works on another person's land, he
can expropriate the land reasonably required if an amicable 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
the administration of the improvement districts which have been incorporated under the Water
Act for irrigation, waterworks, drainage, dyking, street-lighting, providing financial aid to hospitals, 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 Mission City.
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. A large number of communities have been
incorporated into improvement districts under the Water Act to operate community projects and
provide essential amenities.

Comptroller of Water Rights
The Water Rights Branch is responsible for the administration of all use of
water in British Columbia under the provisions of the Water Act. For this purpose
a licensing system has been developed over the course of the last century, from its
origin in the Gold Fields Act of 1859 through a gradual evolution to the first Water
Act of 1909 and on to the present Water Act, which has been substantially unchanged since 1939. In addition to administration of water use, the Water Act also
provides for the incorporation of improvement districts which provide local services
in water-related fields and other fields such as street-lighting and the financing of
hospitals. In addition to its purely administrative functions, the Water Rights
Branch carries out a great number of engineering studies on water matters, including
erosion and flood damage and some aspects of pollution control. The capital undertakings of improvement districts are given careful scrutiny, both with regard to
economic feasibility and engineering adequacy, and some engineering services are
provided to improvement districts and to groups proposing to organize districts for
water-supply purposes. During 1967 a large number of water-supply feasibility
studies were carried out, and final design and supervision of construction were provided to improvement districts by both headquarters and regional engineering staff.
The division of responsibilities between the Water Rights Branch and the Water
Investigations Branch, which carries out water investigations of a greater scope, is
somewhat flexible, and a close liaison has been maintained between these two
branches of the Water Resources Service. There is a sharing of some head office
facilities, such as filing, and the district offices of the Water Rights Branch, because
of their location, provide office facilities and staff assistance to the Investigations
Branch, which in return provides specialist engineering advice to the Water Rights
The 1967 year was an unusual one in terms of water supply because it provided
both the most severe flood threat and the most severe drought of recent years. The
flood threat developed in most drainage areas in the Interior of the Province as a
result of a heavy snow pack combined with a delayed commencement of the spring
snow-melt. An emergency programme of dam inspections was carried out by the
district offices together with a review of developed areas subject to flood danger.
Emergency protection in the form of dyking and channel improvement was provided
in some areas. However, due to extremely favourable snow-melting conditions, a
major flood did not materialize, although extremely high stages were reached on
many streams, including major rivers such as the Fraser, Kootenay, and Columbia.
During the flood period, flood-routing calculations were carried out by the
Power and Major Licences Division to ensure the operation of major storage reservoirs to provide the greatest degree of flood control obtainable.   Significant flood-
stage reduction was achieved on the Fraser River as a result of the operation of
power storage reservoirs on the Nechako and Bridge Rivers, and on the Kootenay
and Columbia Rivers as a result of the operation of the new Duncan Lake reservoir,
which came into use for the first time in May, 1967.
The excellent co-operation of the licensees, British Columbia Hydro and Power
Authority and Alcan Limited, is gratefully acknowledged.
The summer of 1967 was the driest for many years in most parts of the Province, and water shortages developed in many areas as a result. Small streams in the
Okanagan, Kamloops, Lower Mainland, and Vancouver Island areas were particularly affected. These shortages resulted in heavy demands on our District Engineers
to regulate the use of water under existing water licences.
The trend of steadily increasing activity in the water-licensing field, which has
been evident in recent years, continued through 1967. Applications for new licences
and amendments to existing licences both reached new highs. In spite of the problems at the district office level from the flood threat and water shortage and at head
office from numerous changes of staff, a record number of water licences were issued
during the year. Unfortunately, the number of applications outstanding also reached
a new high.
The Improvement Districts Division was active during the year. Ten improvement districts were incorporated, making a year-end total of 328 districts. As a
result of the Federal Government ARDA programme, construction activity by irrigation districts in the Okanagan remained at a very high level. In 1967 a record
$5,219,000 in improvement district debentures received the Provincial guarantee.
The Power and Major Licences Division was occupied during the year with
work associated with approval of plans and other aspects of the three Columbia
River Treaty projects and the Peace River project, all of which were under active
construction during the year. A number of other projects were also reviewed, and
a continuing programme of inspection of all major dams in the Province was instituted. Technical services were provided to support the Deputy Minister in his
position on the Columbia River Treaty Permanent Engineering Board and the
Comptroller on the Advisory Sub-committee to the Canada-British Columbia
Liaison Committee. Extensive use of the computer was made for power-licence
rentals, statistical studies of water use, and other engineering studies.
An unusual number of staff changes took place during 1967. Mr. R. A.
Pollard, District Engineer at Nelson, transferred to the Water Investigations Branch,
and was replaced at Nelson by Mr. T. H. Oxland from Water Investigations Branch.
Mr. J. C. Purnell resigned as District Engineer at Prince George to take a position
with the Government of Alberta, and was replaced at Prince George by Mr. C. E.
Wilson, who had been Assistant District Engineer at Kelowna. Mr. P. G. Odynsky
transferred to Victoria as District Engineer, and was succeeded at Kamloops by Mr.
D. E. Smuin, who had been Acting District Engineer at Victoria. Mr. E. D.
Anthony transferred from the Improvement Districts Division to become Assistant
District Engineer at Kamloops. Mr. H. H. Nesbitt-Porter resigned from his position
as Assistant District Engineer at Kamloops. Messrs. B. A. Lambert, S. B. Carroll,
D. W. Roberts, and E. W. F. Mueller joined the engineering staff as Assistant District Engineers at Prince George, Kelowna, Nelson, and Mission respectively. Mr.
D. S. Sinclair resigned as engineer in the Power and Major Licences Division and
was replaced by Mr. J. W. Ngai.
There were also a number of changes in senior clerical positions. Mr. R. D.
B. Lyttle resigned as Inspector of Improvement Districts in the Improvement Districts Division and will be replaced early in 1968 by Mr. A. O. Ferguson.   Mr. E.
J. Nye, head of the Applications Section in the general office, and Mr. W. W.
Klingsat, head of the Amendments Section, both transferred to other departments
and were replaced by Mrs. B. Dickinson and Mr. J. D. Christian respectively.
Mr. R. S. Bussey transferred from the Lands Service to fill a vacancy as Senior
Clerk, Groundwater Section. A number of staff changes also occurred in junior
positions, including four new draughtsmen in the five junior draughting positions
in the draughting office.
The effect of these widespread staff changes has been felt in reduced work
flow and increased backlog in licensing work, with the result that applications for
licences outstanding reached a new year-end high of 1,789. Engineering vacancies
have been particularly difficult to fill, and positions have remained vacant for
long periods.   At the end of the year three engineering positions were vacant.
The activities of 1967 are recorded in greater detail in the reports of the
separate divisions of the Water Rights Branch, which follow.
W. R. Tuthill, Chief of Division
The Comptroller of Water Rights administers the Water Act and grants
rights to the diversion of water within the Province for almost every conceivable
use. Licences are issued for domestic, waterworks, irrigation, mining, industrial,
power, storage, and other purposes and are required, with few exceptions, before
any person, company, corporation, community, or government 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.
During the year, records were reached in the number of new applications
received, 1,386, and licences issued, 1,734. The number of applications pending
again reached a new high, increasing to 1,789, up 88 from the previous high set hi
The main functions and details of activities for 1967 of the General and
Draughting Offices are contained in their reports, which follow.
General Office
The General Office of the Water Rights Branch has a staff of 16, made up of
a Chief Clerk, a Principal Clerk, a Senior Clerk, three Clerks 3, three Clerks 2,
two Clerks 1, two Junior Clerks, one Clerk-Stenographer 3, one Clerk-Stenographer
1, and one Clerk-Typist 2. In accordance with the various functions, it is divided
into sections dealing with applications, amendments, rights-of-way, ground-water,
and filing.
The Applications Section processes all new applications for water licences,
and for approvals for both the non-recurring use of water, and for making changes
in and about streams. It compiles and maintains indexes by name, by file number, by
 EE 22
licence number, and by water district, and makes use of these and the records of
the Accounting Section, and of the Draughting Office, when processing applications.
If objections to the granting of a licence are received, these are carefully
investigated before adjudication of the application; in some cases the Comptroller
may hold a formal hearing before reaching a decision.
The Amendments Section is responsible for processing all applications for
the amendment of existing water licences, whether by apportionment, by transfer
of appurtenancy, by change of works, by authorizing additional time in which to
construct the works, or by changing the purpose for which the water may be used,
etc. It is also responsible for maintaining a record of all licences for waterworks
purpose, and for processing and recording all applications for the incorporation
under the Water Act of water-users' communities. There was a total of 77 water-
users' communities at the end of 1967.
The Rights-of-way Section is responsible for processing applications for permits for rights-of-way over Crown land. These permits authorize the occupation
of Crown land for pipe-lines, ditches, dam-sites, flooding, and any other works
authorized under a water licence. Permits are issued concurrent, for example,
with the issue of water licences authorizing works which would affect Crown lands.
The Filing Section is responsible for maintaining the Department's general
filing system, which contains some 20,000 active files, and for the distribution of
all incoming mail that is not connected with current applications.
During the year under review a record number of water-licence applications
has been received. A noticeable feature has been the number of applications for
water licences to authorize the supply of water to subdivisions, which necessitates
close co-operation with the Public Utilities Commission. Also noteworthy is the
increasing number of objections to applications being received, which entails considerable additional work both by the district office staffs and by the General Office.
Numerous personnel changes have occurred in the General Office during 1967,
including two resignations, three transfers within the Government Service, and
seven interoffice promotions. In connection with these changes, four new members
have joined the staff.
The principal activities of the General Office in the 12-month period ended
December 31, 1967, are shown in the following table, together with the same data
for the five preceding years:—

EE 23
Administrative Draughting Office
The Administrative Draughting Office is composed of a Chief Draughtsman,
a Supervising Draughtsman, nine draughtsmen, and one clerk. The 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 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 Branch, 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 1967, 12 new districts were
incorporated and the boundaries of 38 districts were amended. Considerable time
was also spent by the staff on engineering drawings for the Improvement Districts
Division during 1967.

M. L. Zirul, P.Eng., Chief of Division
Past experience has demonstrated that the administration of water licences
could best be handled on a regional basis, with the regional officials having relatively
wide jurisdiction. In this way, questions and disputes arising from the use of water
or other exercise of rights granted under water licences could receive prompt attention and settlement or clarification on a local basis. Accordingly, regional offices,
each in charge of a District Engineer, have been established at various centres in the
Province, these offices at present being located at Kamloops, Kelowna, Nelson,
Prince George, Mission City, and Victoria.
Technically, the function of the District Engineers is to assist the Comptroller
of Water Rights in the administration of the Water Act within the regions for which
they are responsible. They are empowered to exercise authority with respect to the
use of water under water licences and approvals issued under the Water Act and
have responsibility for public safety with respect to any hazard imposed by impounded water, or threat to the quality of water due to disposal of sawdust, timber,
tailings, gravel, and similar substances. Any person to whom an order of the Engineer is directed has the right of an appeal to the Comptroller and thence to the
Lieutenant-Governor in Council. The infrequency of appeals is a measure of the
effectiveness of this method of administration.
All new applications for water licences, applications for approvals under the
Water Act, and applications for amendment of existing licences are investigated and
reported on by the District Engineers, the recommendations contained in the reports
forming the basis for decision by the Comptroller for disposal of the applications.
The District Engineers, therefore, have a major responsibility as advisers to the
Comptroller on allocation of the use of the water resources of the Province.
In addition to the administrative duties connected with water licensing, the
staff of the district offices report to the Comptroller on water damage resulting from
flooding or erosion and have designed and carried out a number of projects in cooperation with owners desiring to protect their properties. They have prepared a
number of water-supply reports covering waterworks or irrigation water supply to
new areas and rehabilitation of existing expended works. During the report period,
Kamloops office assisted the Darfield Irrigation District in the North Thompson area
with preparation of contract documents for construction of a new water-storage dam
and acted as the district's engineers in supervision of construction of the project.
The Kelowna and Prince George offices provided staff to assist the Improvement
Districts Engineering Division in supervision of construction of water projects at
Oyama and Fort Nelson respectively. District Engineers were also assigned special
duties in the early part of the year in connection with preparations to reduce the
hazard of anticipated high water levels expected to result from the excessive winter
snow pack indicated on most watersheds in the Province.
The district offices again operated under the handicap of being short staffed as
a result of resignations and transfers of engineers. There is every hope, however, of
having all vacant positions filled early in the new year.
Work carried out by the district offices is summarized in the following table:—

Kamloops District Office
D. E. Smuin, P.Eng., District Engineer
The Kamloops office administers the Water Act in the Ashcroft, Cariboo, Kamloops, and Nicola Water Districts within South Central British Columbia. Normal
precipitation varies from 7 inches in the Ashcroft area to 40-plus inches in the more
northerly parts of the North Thompson Valley. This variation makes for a variety
of water-use problems, including water shortages in areas of deficient rainfall and
flooding in others.
The normal complement of the Kamloops District Office comprises a District
Engineer, two Assistant District Engineers, an engineering assistant, a clerk-
stenographer, all full-time employees, and one or two student assistants during the
summer. During the report year Mr. D. E. Smuin, P.Eng., replaced Mr. P. G.
Odynsky as District Engineer, and Mr. E. Anthony, P.Eng., was appointed as Assistant District Engineer, replacing Mr. J. Wester. Assistant District Engineer H. H.
Nesbitt-Porter resigned to return to Ireland.
The 1967 irrigation season was unusual. Firstly, a heavy snow pack resulting
from higher than normal snowfall and a delayed spring provided water to fill most
storage reservoirs during the run-off period, hence irrigators with storage reservoirs
were able to take advantage of the long, hot growing season which followed. Secondly, the summer months were exceptionally hot and dry, no measurable precipitation occurring until well into September. As a result, shortages were reported as
early as July by users dependent upon natural stream-flows for their water supply.
The regulation of water use under licences demanded considerably less time than
during some dry summers experienced in previous years; however, some streams did
require considerable attention.
A heavy programme of dam inspections was carried out because of the severe
flood potential imposed by the delayed spring and heavy snow pack.
Applications for water licences have increased in number each year, in keeping
with the general expansion within the region. More applications are received for
amendment of existing water licences as a result of subdivision of land and changes
in methods of water use. The continued replacement of ditch irrigation by sprinklers
has extended the use of the available supply of water in some arid regions.
Shortage of staff affected the work output of the Kamloops office; nevertheless,
several important projects were carried out, including the supervision of construction
of a storage dam for the Darfield Irrigation District. The project was not completed,
but it is anticipated that water will be stored for the use of the district during the
1968 irrigation season.
A summary of the engineering investigations and studies carried out by the
Kamloops District office is presented below.
Engineering Investigations and Studies
Conducted site investigation in connection with licensee's proposal to construct
a 33-foot-high earth-fill storage on Yook Lake near Ashcroft Manor and inspected
construction and back-filling of outlet sluice. The project has been halted pending
agreement on method of providing internal drainage for the dam.
Ordered lowering of spillway dam on Charcoal Creek near Chase and supervised performance of order.
Reviewed consultant's plans and reported to Comptroller regarding a proposed
concrete gravity dam on Cherry Creek near Savona, a proposed earth-fill dam on
Little Disdero Lake near Kamloops, and a dam to increase the Heffley Creek Irrigation District's storage on Community Lake near Heffley Creek.
Investigated and reported on Marshall Springs as a source of water supply for
Lower Nicola Improvement District.
Investigated and reported on erosion damage on Guichon Creek at Lower
Nicola and recommended remedial work.
Prepared cost estimate for new pipe-line proposed by irrigation licensees on
East Canoe Creek at Salmon Arm.
Provided engineering services to Darfield Irrigation District in awarding of
contract and supervision of construction for an earth-fill storage dam on Smith Lake.
Carried out field studies in connection with preparation of engineering reports
covering a domestic water supply for Birch Island and a diversion from McGillivray
Creek for additional irrigation-water supply to Heffley Creek Irrigation District.
Kelowna District Office
R. J. Talbot, P.Eng., District Engineer
The Princeton, Fairview, Grand Forks, Vernon, and Revelstoke Water Districts
fall under the jurisdiction of the Kelowna District office. These districts comprise
the drainage basins of the Kettle, Similkameen, and Okanagan Rivers, the Shuswap
River above Sicamous, and part of the Columbia River from its confluence with the
Canoe River downstream to Arrow Lakes.
The weather during 1967 in this area was somewhat drier and a few degrees
warmer than in past years, sunny and hot weather with light to heavy breezes prevailing nearly every day from mid-April to mid-October. Snow-course measurements in the Okanagan area at the beginning of the season showed a water content
of up to 30 per cent above average for most snow courses; however, the lack of
spring rains during the snow-melt period resulted in a lower than expected run-off
into Okanagan Lake.   Okanagan Lake rose only 2>/i feet and peaked at 1.3 feet
lower than the regulated high water level of 1,123.79 feet g.s.c. It is estimated that
the run-off from the Okanagan watershed above Penticton, for the 1966/67 water-
year, was only about 67 per cent of average.
The activities carried out by the Kelowna office were limited to some degree
by shortage of staff. The vacancy left by the transfer of Mr. S. B. Mould in
1966 was not filled until October, 1967, when Mr. S. B. Carroll joined the staff as
Assistant District Engineer. The following month Mr. C. E. Wilson won a competition for a District Engineer's position at Prince George, and the vacancy left by his
transfer from Kelowna has not yet been filled.
The increase in the number of new applications for water licences received
possibly results from the two consecutive dry years experienced in the valley.
Investigations were carried out and reports prepared for amendment of existing
licences covering areas which had become subject to extensive subdivision and therefore entailed a large amount of detailed work in the preparation of the reports.
The high volume of run-off anticipated for the Okanagan region did not
materialize, and instead the long steady period of hot dry weather resulted in high
evaporation losses, which caused an abnormal demand for water for irrigation. The
Naramata Irrigation District's mountain storage reservoirs, which normally last to
August 25th, were empty by August 9th. The district obtained approval to pump
irrigation water from Okanagan Lake for the remainder of the season. Most
orchardists in the Okanagan Valley irrigated until September 30th and some to
October 15th because of the continued hot dry weather.
Strict regulation of water use was required on most of the streams in the district. A water-shortage problem on Myers Creek, which crosses the International
Boundary near Rock Creek, necessitated liaison with officials of the State of Washington. The situation on Christian Creek, near Armstrong, became explosive when
domestic licences had to be restricted to allow water for use for prior irrigation
Threatened high water due to the excessive winter snow pack in some areas
caused the services of this office to be called upon for several items of emergency
flood-protection work during the early part of the season. Dykes were constructed
on 3 miles of Mission Creek near Kelowna. A short section of dyke on the Tula-
meen River was strengthened where that river threatened the town of Tulameen.
A flash rainfall on June 2nd caused extremely high flows in the Eagle and Perry
Rivers, near Malakwa, causing concern to the people of the area.
We continued to gather hydrologic data, including a summary of storage water,
snow data, rainfall, air conditions, ground conditions, and stream run-off, in the
Terrace-Esperon watershed near Whiterocks Mountain. Hydrologic studies were
carried out to determine the possible effect of issuing water licences for industries
such as the proposed Brenda Mines operation near West Summerland, where large
flows of water would be involved.
During the past year, inspections were carried out on six storage dams being
reconstructed in the area and on repair of gate-works on three other dams.
Engineering Investigations and Studies
Feasibility studies were prepared for the rehabilitation of water-distribution
systems for Ellison Irrigation District near Kelowna and for Covert Irrigation
District near Grand Forks. A report covering water-storage possibilities on the
Fortune Creek watershed was prepared for the City of Armstrong.
Field data were collected for preparation of a report on the rehabilitation of
Okanagan Mission Irrigation District's irrigation system.    We prepared a design
EE 29
and contract documents and supervised the construction of a lVfj-mile diversion
ditch with ancillary works from Shinish Creek to Chain Lake, Princeton Water
District, a project proposed to freshen the water of Chain Lake and relieve the alga?
problem in that lake. This office provided an engineer and necessary survey personnel to assist the Improvement Districts Engineering Division in the supervision
of the reconstruction of the irrigation system of Wood Lake Irrigation District.
This work is being done by the district's own crews.
Mission City District Office
E. G. Harrison, P.Eng., District Engineer
The Vancouver and New Westminster Water Districts in South-western
British Columbia, totalling approximately 40,000 square miles, are administered
by the Mission City District office. The portion demanding the most attention
is the South Coastal and Lower Fraser Valley region, which is the most densely
populated and highly industrialized area of the British Columbia Mainland.
The Mission office was short one staff member until July, when Mr. E. E. W.
Mueller commenced duties as Assistant District Engineer. The staff now consists
of a District Engineer, Assistant District Engineer, clerk-stenographer, and two
engineering aides. The engineering aides are employed on a continuing basis to
assist in dispensing with a heavy backlog of final licence surveys and related field
and draughting-room work.
Above average run-off from snow-melt into the Fraser River resulted in that
stream reaching dangerous levels, and a high of 22.8 feet was recorded on the
gauge at Mission on June 21st. Several flooding complaints, attributable to seepage
through the dykes and to poor drainage of streams within the dyked areas, were
The general lack of rainfall experienced in the region resulted in water shortages in many areas, particularly on small streams without upstream storage and
springs. This resulted in the receipt of many complaints of water shortage, as well
as disputes between licensees. Some disputes were serious enough to involve civil
actions. Disputes over waste were most prevalent in the South Chilliwack area.
The north side of the Fraser Valley between Mission and Pitt Meadows, which
suffers from lack of water at the best of times, experienced severe shortages in both
ground- and surface-water supplies. Similar conditions existed on the Sechelt
The Whistler Mountain, Alta Lake, and Green Lake areas north of Squamish
are developing into major all-year resorts, this trend being accelerated by the
proposal to hold the 1972 Winter Olympics in the area. Much time and attention
were allocated to investigating the several applications for water licences arising
from the development of new ski areas and the accompanying accommodation
Summer-resort interest on the Sunshine Coast is also at an all-time high, and
the attendant interest in water for domestic supplies has required increased attention.
Agriculture in the Lower Fraser Valley tends toward more intensive use of
the limited arable land available, and irrigation is now being practised on the
majority of farm lands, including pastures. The equitable distribution and maximum beneficial use of existing water supplies in this area is a major concern of the
Mission office. The gradual change-over from flood irrigation to sprinkler irrigation is resulting in a higher water-application efficiency.   Water-users in the Lower
Fraser Valley are becoming more and more conscious of water-supply limitations
within their areas.
The District Engineer assisted in the organization of improvement districts
and water-users' communities proposed at Gower Point near Gibsons, D'Arcy on
Anderson Lake, Williams Creek near Pitt Lake, and Adams Brook near Chilliwack.
Engineering Investigations and Studies
An engineering report covering the feasibility of establishing a domestic water
supply was prepared for the residents of the Stillwater area near Powell River.
Water-supply possibilities for the Anmore-Belcarra-Bedwell Bay area were
investigated and reported on.
Data regarding a water supply to the area were compiled for a presentation to
a ratepayers' group in the eastern portion of the Municipality of Maple Ridge.
A report covering a camp water system near Gibsons was prepared for the
Girl Guides Association.
A study of water-flow through Hatzic Slough drainage structures was conducted in connection with resolving a problem of flooding in Hatzic Lake.
Advised the South Pender Harbour Waterworks District regarding storage and
diversion possibilities on an unnamed lake.
Nelson District Office
T. H. Oxland, P.Eng., District Engineer
The Nelson, Kaslo, Cranbrook, Fernie, and Golden Water Districts, which
comprise some 26,000 square miles in the south-east corner of British Columbia,
are administered by the Nelson District office. This office is staffed by a District
Engineer, two Assistant District Engineers, a field-survey party chief, and a clerk-
stenographer, all full-time employees. During the summer two student survey
assistants were employed to assist primarily with final-licence surveys.
The weather in the Kootenay area varied from a mild wet winter, through
a cool spring, to a very hot dry summer. A very heavy winter snow pack
threatened to cause general flooding during freshet time. The cool late spring,
however, resulted in a prolonged snow run-off, which reduced the flood danger.
Above average flows were recorded from most watersheds throughout the area
during the summer.
As a result of the flood threat, this office supervised two flood-control projects
in the early spring. The major project included the survey and raising of some 55
miles of the Kootenay River dykes in the Creston area. A smaller project involved
dyke and revetment construction to control the Kicking Horse River through the
Village of Golden.
While the summer was unusually hot and dry, water supplies were generally
adequate in most sections of the district. There were isolated instances of disputes
among users because of water shortage, but these were generally resolved amicably.
Severe forest fires in the Nelson District burned through the watersheds of
several small streams. It is anticipated that these fires will have an adverse effect
upon spring run-off and summer water supplies on the streams involved.
There was an unusual number of requests from improvement districts and
water-users' communities asking for assistance in connection with rehabilitation of
present works or for reports on the feasibility of expanding present services and
systems. The Nelson District Engineer holds a membership seat on the technical
planning committees of three regional districts. The increased activity of these
regional districts has made additional demands on staff time.
 Sinkut River near Vanderhoof before and after removal of log jam.
This year the office staff continued the design and supervised the construction
of the new well, pumphouse, and water delivery-works for the Fort Steele restoration project. The pump went into operation in July. Design is now being considered for a new concrete reservoir for the system.
We also undertook to design and supervise construction of a new intake dam
for the Village of Silverton. This design is now in hand with construction planned
for next summer.
Personnel changes during the early summer resulted in three new staff members
coming to this office—the District Engineer, one Assistant District Engineer, and
the clerk-stenographer. These staff changes resulted in some interference with work
production, as new members required time for familiarization with the work carried
out and with the region.
There was an increase in the number of applications for water licences received
in 1967 over the two previous years. Approximately 120 applications are still held
in abeyance pending the approval of construction of a water-supply system for the
Ootischenia Improvement District near Brilliant.
There has been a considerable number of applications from the Krestova area,
related to the subdivision and sale by the Land Settlement Board of land formerly
held by the Doukhobor community.
Engineering Investigations and Studies
Engineering reports covering the feasibility of establishing domestic water
supplies were prepared for the Improvement Districts of Ootischenia near Castlegar,
Slocan Park on the Slocan River, and Beaver Falls near Fruitvale.
Studies were initiated preparatory to the preparation of engineering reports on
the rehabilitation of existing works for the Vermillion, South Slocan, Silverton,
Meadowbrook, Balfour, Krestova, Oasis, and Canal Flats Improvement Districts,
Ainsworth and Crawford Bay townsites, Dry Gulch Water-users' Community, and
Coldstream Water-users' Community.
Some 20 flooding and erosion problems were investigated, the major problems
occurring on Kicking Horse River at Golden, Four Mile Creek near Nelson, Goat
River at Creston, McKay Slough at Kimberley, Dutch Creek near Canal Flats, and
Croasdaile Creek near Crawford Bay.
Logging operations affecting the water supply of streams were investigated on
Giveout Creek near Nelson, La France Creek near Procter, Bradley Creek near
Nelson, Coffee Creek near Ainsworth, Pedro Creek near Winlaw, and Tito Creek
near Creston.
Prince George District Office
C. E. Wilson, P.Eng., District Engineer
The Prince George, Quesnel, Peace River, Liard, Atlin, Fort Fraser, Hazelton,
and Prince Rupert Water Districts, comprising approximately two-thirds of the area
of British Columbia, are administered by the Prince George District office. This
year an Assistant District Engineer was added to the staff of District Engineer,
Engineering Assistant, and stenographer. One student assistant is employed during
the summer survey season to assist with final-licence surveys.
Above-average winter snowfall and a delayed spring resulted in high river-
flows which caused flooding and erosion at Prince George and Quesnel, as well as
causing distress to many land-owners throughout the area. The maximum recorded
water level for the Fraser River at Prince George was 2 feet 3 inches lower than in
1948 and one-half inch lower than 1964. The summer was hotter and drier than
normal, resulting in a few localized water-shortage problems.
EE 33
The increase in the number of new subdivisions, attributable to the rapid
growth within the Prince George area, has intensified the interest in forming
improvement districts for the purpose of establishing communal water supplies and
for the up-grading of existing systems. Several meetings were held with area residents, organizing committees, and Trustees in this connection.
The district office is providing engineering services to Fort Nelson Improvement District for the design and supervision of construction of an extension to its
water and sewer systems. Work this year included provision of a 25,000-gallon
wood-stave storage tank.
As in the past few years, we continued to assist the Groundwater Division in
the collection of data on observation wells in the Prince George area.
The District Engineer attended meetings of the Technical Planning Committee
of the Bulkley-Nechako Regional District.
Engineering Investigations and Studies
Inspected areas subject to potential flood damage before the spring freshet, and
in several cases recommended preventive measures, including construction of a
dyke along the Fraser River at Quesnel and provision of a temporary gate structure
to prevent flooding in the Hudson's Bay Slough area at Prince George.
Inspected numerous small dams in connection with the spring flood threat and
a dam under construction on Silverthorne Creek and one recently altered on Upper
Dragon Creek near Quesnel. Reviewed design and construction of a storage dam
for Upper Fraser Spruce Mills with the company's consulting engineer.

complaints of flooding on Nukko Creek, Pantage Creek, Eaglet Lake, and Sinkut
River.   Supervised removal of log jam on Sinkut River near Vanderhoof.
Prepared a report on flooding of the Kispiox River near Hazelton.
Investigated water shortages on East Murray Creek, Manzinger Creek, and
Oscar Lake.   Requested remedial action in the case of Oscar Lake.
Investigated and made recommendations with respect to erosion problems on
the Fraser River near Quesnel and on an unnamed creek near Fort St. John.
Undertook removal of a beaver dam from private property on Upper Dragon
Creek near Quesnel following complaints of interference with licensed irrigation-
water supply.
Investigated and reported on effect of proposed logging operation on Wathl
Creek at Kitimat.
Designed and supervised installation of elevated water-storage tank and water-
and sewer-system extensions for Fort Nelson Improvement District.
Met with local residents interested in formation of improvement districts at
Hixon and in the Beaverly, Pineview, Buckhorn, and Blackburn areas near Prince
Attended meetings of Trustees of Charella Gardens Waterworks District, Star-
lane Waterworks District, and College Heights Improvement District to discuss
solutions to their water-shortage problems.
Attended meeting of Trustees of all improvement districts in the Prince George
area to advise on common problems in finance and administration.
Victoria District Office
P. G. Odynsky, P.Eng., District Engineer
The Victoria District office administers the Water Act throughout Vancouver
Island, the Gulf Islands and adjacent islands, which comprise the Victoria, Nanaimo,
and Alberni Water Districts.
During 1967 the office staff consisted of a District Engineer and one engineering assistant. The engineering assistant assisted the District Engineer in making
inspections of applications for water licences, licence amendments, and complaints
of water shortages. Two student assistants were employed during the summer to
carry out final-licence surveys under the supervision of the engineering assistant.
Clerical and stenographic service are provided by the Water Licensing Division.
Excessive winter rainfall resulted in flooding on several streams in December,
1966, and January, 1967, particularly in the south-east part of Vancouver Island.
In contrast, the 1967 summer season was one of the driest on record and resulted
in a number of complaints of water shortages, necessitating inspections and imposing
of restrictions and issue of orders. Rainfall was extremely low during the months
of June, July, and August, Courtenay recording a total of 0.63 inch compared to
an average of 5.07 inches. Rainfall for other centres within the region for the same
period was: Alberni, total 1.04 inches (average 4.27); Nanaimo, total 1.26 inches
(average 4.41); Victoria, total 0.87 inch (average 2.34). September saw the
return of normal precipitation and October was excessively wet.
There was a large increase in the number of applications for water licences for
domestic purpose received during 1966 and 1967. Subsequent inspections of these
applications indicated that the increase resulted from increased purchasing of waterfront real estate for summer-home sites and that the purchasers appear to be well
aware of the diminishing supply of suitable land for this purpose and of limitations
in water supply available for domestic use.
A summary of applications for water licences received and dealt with for the
years following the rezoning of the boundaries of the region administered is shown in
the following table:— Water Water
Applications Applications
Year Received Reported On
1962  186 183
1963  136 113
1964  119 111
1965  151 137
1966  183 139
1967  196 164
There are now 1,336 active conditional water licences and 1,646 active final
water licences under the jurisdiction of the Victoria District office.

safety is corrected.
P. J. Leslie, P.Eng., Chief of Division
The number of improvement districts has continued to increase, and there is
now a total of 328 districts in existence. During the year the following new districts
were incorporated: Anahim Lake Improvement District, Beachcomber Bay Waterworks District, Bennett Bay Waterworks District, Brilliant Waterworks District,
Clear Acres Improvement District, Glen Valley Dyking District, Pender Harbour
Fire Protection District, Scott Point Waterworks District, Trout Lake Improvement
District, and West Hixon Improvement District. The following districts were dissolved: Princeton Fire Protection District, Queenswood Sewerage District, and
Renata Irrigation District.
The object (or objects) for which a district is incorporated is set out in its
Letters Patent. Upon petition of the Trustees, action may be taken to have such
Letters Patent amended to include extra objects, and many districts which were originally incorporated for one purpose now have several. The activities for which the
existing districts are responsible include irrigation, domestic waterworks, dyking-
works, drainage-works, land-improvement works, fire protection, street-lighting, garbage collection and disposal, sewerage-works, parks and playgrounds, cemetery operation, community hall provision and operation, electric-power generation and distribution, mosquito control, hospital provision and operation for provision of financial aid toward building and operation of a hospital, and ambulance service.
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 to raise
money by the imposition of tolls and charges. They are also empowered to issue
debentures to obtain funds for capital purposes, this being the usual method in use.
In many cases, improvement district debentures and the interest thereon are guaranteed by the Province pursuant to the Improvement Districts Assistance Loan Act.
At the present time there is $19,306,600 of such guaranteed debentures outstanding,
of which $5,219,000 was guaranteed during 1967.
During the year, capital works projects to a total value of $3,344,826 were
completed by improvement districts and financed as follows: ARDA, $1,322,826;
district resources and borrowing, $2,022,000.
Section 62 of the Water Act enables districts to obtain current operating funds
as advances from the Province (for certain purposes only) and to utilize the services
of the local Provincial Assessor and CoUector to collect these advances from the
land-owners in the areas and to repay the Province. The purposes for which this
procedure may be used are fire protection, street-lighting, hospital purposes, and
ambulance services, providing they are supplied by a fire protection or hospital district. If a larger amount is required for capital purposes, and collection and repayment by the Provincial Collector in the same year would result in too heavy a tax
burden for that year, an advance of the required amount may be obtained from the
Province, with collection and repayment carried out over a number of years. During
1967 the following advances and collections were made under this section of the
Assessed and collected for repayment of amounts advanced
for the current year  $1,874,787
Amounts advanced in 1967 by the Province repayable in
future years        113,815
Assessed and collected for amounts advanced with repayment
over a number of years        252,075
Total long-term advances outstanding as at December 31,
1967      1,380,096
Engineering Services
The Engineering Section of the Improvement Districts Division provides a
comprehensive technical service to improvement districts, or communities considering incorporating 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.
Where new schemes or rehabilitation of existing works are contemplated, the
Section carries out an engineering investigation, and then prepares a report giving
technical recommendations, cost estimates, and an assessment of the economic feasibility of the scheme.
Once the decision to initiate a project has been made, the district then submits
plans, specifications, and details of proposed financing methods for checking and
approval by the Section. Certain requirements must be met before a recommendation for Government guarantee of a loan will be made. In many instances, details
of a project are discussed at length with the district's consultants, and revisions or
modifications recommended.
In some circumstances the Section assumes full responsibility for the engineering of a project. After the preliminary surveys and investigation have been completed, the Section then prepares final design drawings, specifications, and contract
documents, and finally 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 actively concerned with problems of development.
The following assignments were completed during the year:—
Reports Prepared
Alta Lake Area.—A report was prepared describing two possible schemes for
supplying the community on the west shore of Alta Lake, near Pemberton, with
domestic water. A gravity supply from Scotia Creek would be the most economical,
provided the Pacific Great Eastern Railway Company wished to participate in the
scheme.   A more expensive alternative would be a pumped supply from Alta Lake.
Bamfield.—An investigation was made into possible means of providing a
domestic water system for the community of Bamfield on the west coast of Vancouver Island. Both ground-water and an unnamed lake south of Bamfield were considered as sources of supply, and a report was prepared setting out the probable costs
involved. Preliminary field tests indicated that the quality of water was poor, and
that treatment would probably be necessary. However, even without water treatment, the costs of the scheme were shown to be beyond the financial capabilities of
the community.
Grandview Waterworks District.—The farm water supply serving the Grand-
view Waterworks District near Armstrong was partially rehabilitated in 1966 under
the Agricultural Rehabilitation and Development Act at a total cost of $105,243.
Following completion of the contract, a report was prepared describing the works
installed together with " as constructed " drawings, and including recommendations
for system maintenance and operation, administrative policies, and future system
extensions. The improvements in operating pressures resulting from the first-stage
rehabilitation have severely taxed the older laterals retained in service and has made
the need for further replacements more urgent. A feasibility report covering second-
stage rehabilitation, at an estimated cost of $55,000, has been prepared, and will
be submitted by the district in support.of an application for further ARDA
Southey Point Area, Saltspring Island.—A report examining the possibilities
of providing a domestic water supply to the residents of the Southey Point area
was prepared. The cost of a pumped supply from three rock wells was found to
be excessive, and it was shown that the problem could best be solved by inclusion
in the neighbouring North Saltspring Waterworks District. This district's existing
works have insufficient capacity to supply additional consumers at the present time,
but system modifications to rectify this deficiency are now under consideration.
Stillwater Water-users' Community.—The Stillwater Water-users' Community
is located north of Jervis Inlet on the Lower Mainland coast of British Columbia.
A report, in which the economic feasibility of rehabilitating the existing water
system serving the community was examined, recommended formation of an improvement district and partial rehabilitation at the present time. Future growth
would necessitate replacement of the remainder of the system.
West Howe Sound Area Water Supply.—The West Howe Sound area includes
the Village of Gibsons and six smaller communities, the combined population being
approximately 3,700 persons. Although there is an abundant supply of potable
water for nine months of the year, most of the local sources become depleted during
the hot summer months, and severe restrictions become necessary. At the request
of local organizations, a detailed study of the area was made and a report prepared.
This report included population analyses, a hydrological examination of the possible
water sources in the area, and presented in outline a bulk water-supply scheme for
the area, using Langdale Creek as a primary source. Cost estimates indicated that
the scheme could be installed for a capital cost of approximately $319,000, and
that it could be supported by annual charges of less than $30 per annum per household excluding distribution costs.
Design and Engineering Services
Fort Nelson Improvement District.—The water supply to the Fort Nelson
Improvement District is pumped from the Muskwa River to storage during the
winter months, using a moveable pumphouse which is positioned on the ice after
the river freezes. The system has, in the past, proved cumbersome and expensive
to operate and is now barely adequate to meet increased water demands. A preliminary appraisal of the problem was made, which indicated that extensive redesign
of the system would be necessary, including relocation of the intake, first-stage
pumping plant, and supply main, together with the provision of water-treatment
 EE 38
and silt-removal facilities. The cost of the proposed works is estimated to be in the
area of $230,000. Deficient pressures at the higher elevations in the Hospital Hill
area presented a more immediate problem, and a 25,000-gallon elevated storage
tank, automatic heater, pumping unit, and connecting pipe-lines were designed and
installed under the supervision of the Division during the summer. The cost of the
works, including some minor sewer extensions, is expected to be approximately
Spences Bridge Waterworks District.—Flash flooding of Murray Creek during
the spring resulted in heavy deposits of silt and gravel building up behind the
recently reconstructed Murray Creek dam. During the removal operation, the
sluicegate and mechanism were damaged. An inspection of the damage was made,
and remedial measures recommended.
Village of Ucluelet.—The Village of Ucluelet requested advice regarding augmentation of its water supply and replacement of the main pipe-line supplying the
village and Port Albion. A site survey and investigation were carried out.
Wood Lake Improvement District.—In 1966 approval was obtained under the
Agricultural Rehabilitation and Development Act for rehabilitation of the Wood
Lake Improvement District's irrigation system, and construction commenced in
April, 1967, to designs prepared by this Division. As many of the local fruitgrowers are conversant with the construction and maintenance of irrigation-works,
it was arranged that the district install the system using its own labour force under
the supervision of this Division. Satisfactory progress was achieved, and by the
end of the year 50 per cent of the distribution system (asbestos cement pipe) and
25 per cent of the supply main (ductile iron pipe) had been laid. Work on the
intake diversion dam and sedimentation tank started at the close of the irrigation
season, and is now almost completed. It is anticipated that the remainder of the
work will be completed during 1968, with the possible exception of modifications
to the storage dams in the catchment area. A total of $227,000 was expended
during 1967.   The estimated final cost of the project is $442,000.

H. M. Hunt, P.Eng., Chief of Division
The Power and Major Licences Division is responsible for engineering and
administrative duties in connection with the use of water for power generation and
for other substantial uses.
The various duties performed by the Division include:—
(a) Reporting upon the suitability of all power licence applications, carrying
out an engineering review of plans and undertaking any further investigations that may be required.
(b) Administration of the Water Act in so far as it applies to the use of water
for power purposes, including the calculation and billing of annual
rentals and fees.
(c) Investigation and research necessary to guide the development of Government policy with respect to the utilization of the hydro-electric power
potential of the Province.
(d) Carrying out an engineering review of plans for major licence applications
for industrial and mining purposes.
(e) Compilation of statistics concerning the use of water for all purposes as
a guide to future water-resource planning.
(/)  Inspection of all major dams in the Province.
(g) Provision of technical support for, and representation on, the Columbia
River Treaty Permanent Engineering Board and its working committee.
Major Licensing Administration
All water licence applications for power purposes are scrutinized by an
engineer of the Division for feasiblity and to determine the rentals payable. Where
the amount of power to be developed is fairly substantial, further investigation may
be made by the Division; where necessary, use may be made of specialist consultants.
In the case of major licence applications, special attention is paid to public
safety. This may require carrying out detailed studies or obtaining expert advice
on such matters as the stability of dams and structures, and the problems relating
to unusually large flood flows. In the case of power licences, the utilization of the
hydro-electric potential of any site is reviewed in terms of its economic integration
into the Provincial electrical system.
Other aspects, commonly taken into consideration as being in the public
interest, are the extent to which reservoirs should be cleared of timber, the effects
on fish and wildlife, and the possibility of the use of reservoir areas for recreation.
Existing Licences
The duties of the Division staff with respect to existing power licences consist
of the calculation and billing of annual rentals and fees; the compilation of annual
generation figures for use in calculating rentals and preparing statistical records;
administration in connection with special clauses in licences, including carrying
out the necessary studies and investigations; and interpretation of the Water Act
with respect to use of water for power purposes, including any general matters
pertaining thereto.
In certain major storage licences, notably those applying to the Columbia
River and Peace River power projects, the powers of the Comptroller have been
set forth explicitly in special clauses in the licences. These special clauses cover
such matters as approval of plans for dams and other structures, the clearing of
reservoirs, public access to reservoirs, the release of water from reservoirs, and the
protection of fish and wildlife. Thus an important function of the Power and
Major Licences Division is the implementation of studies and administrative work
necessary to enable the Comptroller to exercise his responsibilities with respect to
such major water-resource projects.
During 1967, work proceeded on the approval of plans for the Peace River
and Columbia River. With major developments of this nature, approval of plans
is a process which is expected to continue throughout the period of construction for
each project.
Because of the highly specialized nature of major dam construction, it is often
necessary for the Comptroller to obtain advice from specialist consultants of internationally recognized stature during the review of plans for major dams. For the
W. A. C. Bennett Dam (formerly known as Portage Mountain Dam), the Department's general consultant is Mr. D. J. Bleifuss, of Atherton, California, who is
actively involved in major dam projects on four continents. Dr. H. Q. Golder, of
Toronto, has been retained as specialist consultant on soils and foundation problems
for this project. Mr. Bleifuss also acted as consultant for the Duncan Lake dam,
while the consultant for the Arrow Lakes and Mica Creek dams is Mr. F. B. Slichter,
of Burke, Virginia. Mr. Slichter was formerly chief civil engineer of the United
States Corps of Engineers, and brings from his career with the corps a wide range
of experience with dams and other hydraulic structures.
The Power and Major Licences Division is responsible for the background
work necessary to make the services of the specialist consultants effective in providing advice to the Comptroller on these major developments. During the course
of this work in 1967, technical meetings were held with these consultants and with
engineers of the British Columbia Hydro and Power Authority and its consultants.
During 1967, visits were made to the W. A. C. Bennett, Arrow, Duncan, and Mica
dam-sites in the company of Messrs. Bleifuss, Golder, and Slichter.
Other Major Licences
The Division is also responsible for the review of plans and documents in
connection with other major licence applications. A number of major licence
applications are being processed by the Branch at present, principally for use in
pulp and paper plants and in mining operations. Worthy of particular mention is
the development by Celgar Limited at Prince Rupert of additional storage by the
raising of the existing dam at the outlet of Diana Lake and the construction of a
new dam on Rainbow Lake to form one large interconnected reservoir. These
dams were the subject of earlier detailed review during the design and construction
stages, and in October of 1967 an inspection was made of the reservoir clean-up
Flood-control Operations during 1967
The flood season for 1967 began with an unusually heavy snow pack, which
was followed by a later than average spring thaw, and by early May the stage was
set for a potentially serious flood.
Studies were undertaken by engineers of the Division to prepare an optimization programme for the use of Provincial reservoir storages to reduce flood peaks on
British Columbia's two major rivers. Working with flood-volume predictions issued
by the Hydrology Division of the Water Investigations Branch and based on snow-
pack observations, studies were made to assess the best method of operating
reservoirs on the Fraser River and Columbia River systems to ensure the greatest
possible flood-control benefit by pre-flood reservoir draught and subsequent controlled flood storage. In this way it was intended that the outflow peaks would be
moderated while ensuring that power generation during the subsequent 1967/68
period of storage draught would not suffer by excessive release of reservoir storage.
Excellent co-operation existed throughout these studies between the Division's
engineers and their counterparts in Alcan, British Columbia Hydro and Power
Authority, West Kootenay Power and Light Company Ltd., the Inland Waters
Branch of the Department of Energy, Mines and Resources, and the Co-operative
Columbia River Forecasting Unit in Portland, Oregon, whose forecasts of flood
flows were invaluable in predetermining day-to-day operation of control gates on
the Columbia River system.
By the combined use of Alcan's Nechako reservoir and those of the Authority
at La Joie and Bridge River, estimated reductions in peak flow of the Fraser River
at Hope from 420,000 c.f.s. to 383,000 c.f.s. were achieved, with an equivalent
drop of about 1.4 feet in the flood stage.
On the Columbia River, operating conditions were complicated considerably
by the fact that Duncan Dam, the first completed of those dams being built under
the International Columbia River Treaty, was still undergoing its initial trial filling
programme, which involved careful control of the rate of rise on the reservoir
level. Consequently the reliability of flood forecasts and the accuracy of the
associated storage studies assumed even greater importance in view of the often
conflicting requirements of safely filling the reservoir while attempting to secure the
maximum degree of flood moderation for downstream areas on the Columbia
River. Viewed in retrospect, however, the regulation of Duncan reservoir and
Kootenay Lake could not have been much improved; Kootenay Lake levels were
reduced about 2 feet by Duncan Dam operation, and the reduced discharge from
Corra Linn Dam at the outlet of Kootenay Lake in turn caused the flood levels of
the Columbia River at Trail to peak about 1.2 feet below those levels that would
otherwise have occurred. Distress to the citizens and damage to property was
thereby alleviated.
Power-policy Planning
An important duty of the Division is to assist in the over-all planning of power
development in the Province. Reviews are made of all potential major developments to determine how they might best fit into a Province-wide power system.
This is a continuing task, as fresh scientific and technological developments constantly alter the economic viability of different projects and thus entail periodic
reassessment of the situation.
Specific fields of study in connection with power-policy planning include the
compilation of historical electric-power generating records and the preparation of
forecasts of future load growth; studies of international power-system developments,
such as the Columbia River; review of other benefits available to the public at
hydro-electric developments; and preparation of an inventory of available undeveloped power resources.
Columbia River Treaty Permanent Engineering Board
The Power and Major Licences Division is responsible for providing technical
support to the Deputy Minister of Water Resources in his capacity as member of
the Permanent Engineering Board. Among the several functions required under
the terms of the Columbia River 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 the Deputy Minister with responsibility to assist the member in the
performance of his duties and to take his place at Board meetings in his absence.
In addition, the Chief of the Division is a member of the recently formed Permanent
Engineering Board Committee, whose function it is to assist the Board in considering
proposals and operating plans received from the Entities.
Meetings of the Board were held in Seattle, Washington, in March, 1967, to
review progress of Entity studies; a joint meeting with the Entities was held on the
following day to discuss study progress and to review a draft of a special operating
programme for the Duncan project; after a tour of inspection in August of the
Columbia River Treaty projects at Libby in Montana and Arrow Lakes, Duncan,
and Mica dams in British Columbia, a meeting was attended in Vancouver to review
progress; later that day a joint meeting was held with the Entities to receive
information on Entity studies; in October the Board met with the Entities in
Ottawa to review construction progress and discuss further Entity proposals regarding reservoir operating procedures.
The Committee to the Permanent Engineering Board was formed in August,
1967, and the first meeting was held in Vancouver during October to discuss the
Entities' proposed power operating procedures for the Columbia River storages in
Canada, and their proposed hydrometeorological network for the Columbia River
basin and neighbouring watersheds. The findings of the Committee were relayed
to the Board at its meeting in Ottawa later that month. In mid-December a joint
meeting of the Committee was held with the Entities' technical staff in Portland,
Oregon, regarding the power operating procedures and hydrometeorological network.
Undeveloped Water Power in British Columbia
In 1954 the Water Rights Branch published a booklet entitled " Water Powers
of British Columbia." Studies subsequent to that date have shown the available
potential to be several times greater than was then anticipated. Because of this, a
review has been made to up-date the information previously published and to make
a more realistic estimate of the Province's undeveloped hydro-electric power resources. In the past, calculations of power potential have been unduly conservative;
it is therefore intended that this situation be corrected, taking into account modern
techniques in the development of major sites and the transmission of power over
long distances.
The Inland Waters Branch of the Department of Energy, Mines and Resources
of the Government of Canada and the Water Rights Branch of the Government of
British Columbia are engaged in the compilation of an index of known undeveloped
hydro-electric power sites in British Columbia, which is itself part of a study covering the whole of Canada. The assembly of basic data was completed some years
ago, and a summary showing the up-dated totals for different areas of the Province
was included in the 1967 Annual Review of Water Powers of British Columbia, published by the Water Resources Service in July, 1967. The next stage of the study
consists of determining the contributions which individual sites can be expected to
make when operated in an integrated system; it is believed that this method of calculating potential output will increase the total from known sites by perhaps as much
as 50 per cent on the present figure of 23,930,000 kilowatts. It must be remembered, however, that many sites have not yet been investigated at all, and it is possible that the ultimate total may be several times that amount.
Developed Hydro Power
The following paragraphs summarize the development of hydro-electric power
in British Columbia during the past two years. For further details, reference should
be made to previous Annual Reports or to the Annual Reviews of Water Powers of
British Columbia.
During the past few years the most massive hydro-electric construction programme in the history of British Columbia has been proceeding on schedule. Two
major dams, one on the Peace River and one on the Columbia River, have been
completed, and two more Columbia River projects are being constructed to provide
power, flood control, and downstream flow regulation. In addition to this the
Aluminum Company of Canada Ltd. (Alcan) recently added a new unit at its
Kemano plant, bringing the total plant installation to 812,800 kw.
Generation and Load Growth
During 1966 the total amount of energy generated by hydro-electric plants in
British Columbia was 17,042,531 megawatt-hours, representing an increase of
11.6 per cent on the corresponding figure for 1965. Thermal-electric generation
amounted to approximately 3,838,000 megawatt-hours, an increase of 18.5 per
cent over the previous year.
 EE 44
The following tabulation shows the statistics for generation and load in the
Province over the last 10 years. Prior to 1957 it had been possible to ignore the
effects of import and export of power and to assume that generation and load growth
were equal, but as these effects are becoming substantial, the difference is now being
indicated (see column 5 of table). The tabulation also shows the over-all percentage changes in the 10-year period and mean annual growth rates (compounded).
It will be noted that the average increase in load over the 10-year period is just over
7.5 per cent, somewhat less than the 45-year average of 7.8 per cent per annum.

Interim Estimate of Electrical Generation during 1967
It is estimated that the total production of electrical energy in British Columbia
during 1967 was in the region of 21,500 gigawatt-hours* (subject to revision).
This generation was supplemented by a net import of energy (mainly from the
United States but including some from Alberta) amounting to about 1,000 gwh.,
to meet a total load of 22,500 gwh. Due to the mild recession felt during 1967,
the total load was not as high as was predicted by the British Columbia Energy
Board 12 months ago (23,700 gwh.), but in spite of this the increase over 1966 was
a healthy 7.3 per cent.
The tabulation below shows the breakdown and comparison with the previous
year. It should be noted that although generation by utilities rose only 2.95 per
cent, most of the extra import of energy was used to meet the load of the British
Columbia Hydro and Power Authority. The increase in utility load therefore
works out to about 11 per cent.

Hydro-electric Power Projects Under Construction
Additional Installations at Existing Plants
The eighth unit at Alcan's Kemano plant commenced operation on February
9, 1967. Cominco is in process of adding a fourth unit at its Brilliant plant on the
Kootenay River.
Peace River Development
Apart from planned additions to existing plants, the next major hydro-power
installation to be completed in British Columbia will be the Portage Mountain
development on the Peace River, which is scheduled for first power production
late in 1968.
The diversion-works for W. A. C. Bennett Dam were completed in time to
withstand the 1964 summer freshet of the Peace River, which was the highest ever
recorded. Fill-placing operations were started in August, 1964, employing a
15,000-foot-long conveyor system, which is the world's largest and was built at a
cost of approximately $10,000,000.
On September 12, 1967, the dedication of Portage Mountain Dam was carried out by Major-General the Honourable George Randolph Pearkes, V.C., P.C.,
C.C, C.B., D.S.O., M.C., CD., Lieutenant-Governor of British Columbia. The
Portage Mountain Dam was then named the W. A. C. Bennett Dam in honour of the
Premier of British Columbia, who concluded the topping-out ceremony by riding
a 100-ton " belly dump " truck to place the last load of fill in the dam.
A total of approximately 11.38 million cubic yards of fill was placed in 1967,
bringing the total placed in the dam to 56.40 million cubic yards. The contractor's
earnings are approximately $75,000,000 plus approximately $14,740,000 due to
extra work orders and labour escalation.
The power-house contract, which was let in 1965 to the Northern, Stewart,
Morrison-Knudson, Perini, and Jones consortium at a price of $77,000,000, started
somewhat slowly, but the rate of progress has improved considerably during the
last year.    The contractor's earnings to date total approximately $62,000,000.
The spillway and low-level outlets contract, which was let in 1966 to the
Kiewit, Dawson, and Johnson consortium at a price of $43,868,000, is proceeding
according to schedule. The contractor's earnings to date total approximately
Other contracts let in 1967 totalled $27,615,000, covering such features as
transmission-line equipment and construction, generators, turbines and governors,
and reservoir debris booms.
Columbia River Development
Arrow Lakes Dam.—Preliminary activities on the project were in progress
in late 1964. These consisted of construction of a pipe-line to the Celgar pulp-
mill, land acquisition, and railroad relocation. Early in 1965 the contract for the
main dam was awarded to Foundation Dravo Limited at a price of $55,000,000.
Construction of the concrete section of Arrow Lakes Dam began in April,
1966, following completion of the cofferdam. It is now virtually complete, and the
cofferdam has been rewatered. The 1,200-foot-long concrete section will include
a navigation lock and reservoir discharge-works. The earth section of the dam
is being constructed simultaneously by bottom-dump barges placing fill material
under water and by conventional equipment on the surface. Progress on the contract to date is ahead of schedule.
A total of $699,250 worth of contracts was let in 1967 covering bank protection at Nakusp.
Duncan Lake Dam.-—-The main contract, for slightly under $16,000,000, was
let in 1964 to Mannix, Standard-General, and Emil Anderson consortium and was
completed in July, 1967. On August 17, 1967, Premier W. A. C Bennett officially
dedicated the project.
Mica Creek Dam.—This dam, towering 800 feet above bedrock, will be the
highest in Canada and thud highest of its type in the world. A contract for the
diversion tunnels, which was let in 1965 to the Perini, Northern, Stewart, Morrison-
Knudson, and Mannix consortium for $21,155,000, has been completed.
The main contract, covering the dam, spillway outlet works, and power intakes,
was let on September 6, 1967, for a sum of $136,261,544. The contract was
awarded to Mica Dam Contractors, a consortium made up of Guy F. Atkinson,
Arundel International, L. E. Dixon International, Commonwealth Construction, and
Dillingham Corporation.
There were no other contracts let in 1967.
Use of Electronic Computing Equipment
Power studies were continued during 1967, using the special computer programme developed for use on the I.B.M. 1620. Various problems relating to the
development of the Peace and Columbia River systems are now under intensive
During 1967 the Data Processing Division of the Department of Industrial
Development, Trade, and Commerce switched over to an I.B.M. 360 system. This
will facilitate the use of the data which have been compiled over the last few years.
Significant improvements are expected in data retrieval and statistical analyses.
Dam Inspection
After a review of other agencies' programmes of dam inspection, a catalogue
of large dams in British Columbia was prepared and a programme of dam inspections instituted during 1967.
During this year eight field trips were made, in which 30 major dams and 13
smaller dams were inspected and reported on. As a result of this programme,
instructions were given to the owners of several dams regarding improvements which
they should make, while a detailed engineering report, covering repair or reconstruction of two dams, was required of another owner.

Water District.
The Water Investigations Branch was formed in late 1962 as a consequence of the creation
of an independent British Columbia Water Resources Service, which took effect on April 1, 1962.
The Hydraulic Investigations Division of the Water Rights Branch was transferred to the Water
Investigations Branch, and it formed the nucleus of the new Branch.
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, which
matters are not directly connected with the administration of the Water Act. 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 the Department and general public in the development and maintenance of water-supply
(b) Flooding, drainage, and stream-erosion investigations to give engineering advice
and assistance in solving water-damage problems.
(2) Hydrology Division:
(a) Snow surveys and snow-melt run-off forecasting to guide judicious utilization of
water supply.
(..) Hydrologic studies of the Province to compile and evaluate basic hydrometeorological data in such a form as to make them readily adaptable.
(3) Groundwater Division: Collection of existing ground-water data and investigation and
evaluation of ground-water 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 on regional basis with an immediate
aim to indicate possibilities of augmenting the existing water supply.
(ft) Investigation and inventory of undeveloped hydro-electric power potential of the
(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: Preparation and review of proposals and projects under the Canada-
British Columbia Joint Development Act and the Canada Water Conservation Assistance Act. Design and supervision of construction of water-damage prevention projects.
(7) 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 to foster better
use of water resource, which is one of the principal physical foundations of the economic development of the Province.

V. Raudsepp, P.Eng.
Chief Engineer
The Water Investigations Branch, which was created in December, 1962, deals
with technical matters related to the water resources of the Province where such
matters are not directly connected with the administration of the Water Act. At the
year-end the staff consisted of 55 permanent and 35 continuous temporary positions,
among which were 31 civil engineers, four geological engineers, and one hydro-
meteorologist.   Five permanent and four temporary positions were vacant.
The principal functions of the Water Investigations Branch are carried out by
six divisions, as follows:—
(1) Water Supply and Investigations Division.
(2) Hydrology Division.
(3) Groundwater Division.
(4) Basin Planning and Power Division.
(5) ARDA Division.
(6) Projects Division.
These divisions are supported by a Draughting Office and a Records Compilation and Reports Section. Both these offices also perform certain services for the
other branches of the British Columbia Water Resources Service.
An account of the work carried out by the Water Investigations Branch is given
in some detail on the following pages.   A few general observations are made below.
Substantial increase was experienced in the volume of work in connection with
water projects under Federal-Provincial financial assistance programmes. This
includes rural water projects under the Agricultural and Rural Development Act
(ARDA) and other major water-development and water-damage prevention projects
under the Canada-British Columbia Joint Development Act and the Canada Water
Conservation Assistance Act.
Under the ARDA programme a total of 44 projects has been approved with
an aggregate construction cost of $22,000,000, and 24 project proposals are receiving study with an estimated cost in the neighbourhood of $10,000,000. The Canada
Water Conservation Assistance Act programme involves three approved projects
with a total cost of $4,000,000, and a number of projects are being actively considered with a total construction cost of $39,000,000. The Water Investigations
Branch has been responsible for the processing of these proposals and for implementing the approved projects by providing engineering services or by inspection of
project execution.
Among noteworthy proposed projects is a study of the proposed Shuswap
River-Okanagan Lake water-supply canal, directed by Mr. T. A. J. Leach, Assistant
Chief Engineer. After preparation of a preliminary report in 1966, work has been
continued on various aspects of this proposal.
Increased attention is being given to British Columbia water resources research
planning and management problems. In addition to Water Investigations Branch
activities, the Civil Engineering Department of the University of British Columbia
agreed to embark on a programme of education and research in the field of water
resources. Other departments of the University of British Columbia and the British
Columbia Research Council are engaged in assignments involving biological and
ground-water studies.
The Water Supply and Investigations Division, under Mr. R. G. Harris, was
under a heavy work load in connection with a number of ARDA projects and project
proposals. Final designs and construction supervision were carried out by Messrs.
J. V. Eby, W. B. German, and P. W. Newson. Messrs. T. H. Oxland and W. B.
German resigned; Mr. J. Wester was transferred to the Projects Division; and
Messrs. L. A. Bergman, R. E. Wells, and J. C. Kwong joined the Division as Hydraulic Engineers.   Mr. S. B. Mould continued to work in the field office at Oliver.
The Hydrology Division, under Mr. H. I. Hunter, was under increased pressure
due to the unusually heavy 1966/67 mountain snow pack followed by an extremely
dry and hot late summer and fall. The resulting spring flood hazard and late-
summer water shortages required additional water-supply forecasts. Increased attention was given to research projects under the International Hydrological Decade
programme. Mr. C. H. Coulson continued to refine spring run-off forecasting based
on snow-survey network.
The Goundwater Division activities were somewhat affected by staff changes.
Messrs. E. Livingston and J. A. McCallum resigned, and Dr. J. C. Foweraker was
appointed Chief of the Division in November. The ground-water observation network was expanded, and water-well inventory, exploratory test drilling, and a number of local water-supply problems received attention.
The Basin Planning and Power Division, under Mr. J. D. Watts, was strengthened by three staff additions. Mr. R. A. Pollard joined the Division as a Senior
Hydraulic Engineer. As mentioned above, increased attention is being paid to
water-resources planning problems.
The ARDA Division, dealing with ARDA water-conservation projects, was
operating under increased work load. Mr. D. J. Pennington, Chief of the Division,
was also actively engaged in the design and supervision of two projects. Messrs.
G. M. Pinfold and N. J. Morison arrived from England to join the engineering staff
of the Division.   Mr. P. M. Brady resigned.
Mr. J. D. C. Fuller, Construction Engineer, continued to be in charge of the
largest ARDA project—rehabilitation of Vernon Irrigation District with a total cost
of $6,600,000, of which a little less than one-third has been spent by the end of 1967.
The Projects Division, under Mr. B. E. Marr, is being gradually developed.
Messrs. J. Wester, P. M. Brady, and W. Tempest joined the engineering staff, and
the Division moved to new offices at 1106 Cook Street, Victoria. A number of
projects and proposals under the Federal-Provincial assistance programme were
under study.
Senior members of the Water Investigations Branch continued to participate
in a number of committees dealing with water-resource matters, such as several
committees in connection with ARDA activities, the National and Provincial committees for the International Hydrological Decade, Hydrology Sub-committee of the
National Research Council, Co-ordinating Committee for Hydrometeorological Networks, several Federal-Provincial joint committees on proposed water projects and
other water studies, Advisory Committee for Water Resources Research at the
Science Secretariat of the Privy Council, Agricultural Engineering Science Advisory
Committee, Flood Research Advisory Committee at the University of British Columbia, and Spillway Design Flood Committee of the Canadian National Committee
for International Committee on Large Dams.
T. A. J. Leach, P.Eng., Assistant Chief Engineer
Following completion of the Shuswap River-Okanagan Lake water-supply canal
preliminary report in 1966, an extension of this investigation was made to determine
what effect an ultimate diversion scheme might have on the Shuswap and South
Thompson Rivers.
The canal diversions from the Shuswap River near Enderby under ultimate
Scheme 3 are based on providing water (a) each year for irrigation, domestic, waterworks, and industrial purposes to the North Okanagan (Enderby to the north end
of Okanagan Lake) plus (b) supplementary water in dry years to Okanagan Lake.
In determining these requirements, a population of some 281,000 was assumed together with the irrigation of 183,000 acres of existing and potentially irrigable land.
These figures are four and three times respectively of the 1966 development.
In the follow-up report entitled " Effect of Shuswap River-Okanagan Lake
Water Supply Canal Operation—Scheme 3," May, 1967, it was found that with
Mabel Lake storages varying between 57,000 and 191,000 acre-feet the above requirements could be met and at the same time adequate residual discharges in the
Shuswap River could be maintained downstream of the canal diversion at Enderby
during the irrigation season.
Thus, by lowering the outlet of Mabel Lake, it would be possible to store some
191,000 acre-feet of water without increasing the maximum lake-levels over those
that have occurred in the past (1922-66). Under this type of regulation, the freshet
flows of May to July, inclusive, would be reduced downstream of Mabel Lake. However, after allowing for canal diversions, the residual discharges at Enderby in the
most extreme drought would be at least 1,100 cubic feet per second in April with
higher values in May, June, and July as Mabel Lake filled. Finally, since a major
portion of the storage would be released during August and September, the historic
discharges at Enderby for these months would be substantially increased.
The canal diversions in an average year amount to about 5 per cent of the
annual discharge of the Shuswap River at Enderby and to some 22 per cent for the
most extreme drought of record (1929).
It has been suggested that with minor modifications the water-supply canal
could also serve as a navigation channel. In actual fact, it is anticipated that in such
a case the canal would have to be lowered some 20 to 30 feet and major changes
would be required in order that water would be passed through to Okanagan Lake
only in the years when it is required (about 27 per cent of the years). It is estimated
that the annual operating costs for a water-supply and navigation canal would be
approximately double that required to provide water supply only.
The modifications in the Shuswap River inflows to Shuswap Lake through the
operation of ultimate Scheme 3 would reduce the Shuswap Lake elevations by about
0.3 foot in the high inflow months of June and July in an average year, while increases in the fall and winter months would be between 0.4 to 0.8 foot. The accompanying effect on the South Thompson River discharges at Chase would be minimal.
Future Water Requirements in the Shuswap and
South Thompson Watersheds
Under the aforesaid Shuswap River-Okanagan Lake Water Supply Canal—
Scheme 3, some 11,000 acres of land could be irrigated within the central portion
of the Shuswap watershed between Enderby and Armstrong by direct diversion from
the canal.
A previous preliminary report entitled "North Okanagan Irrigation and
Domestic Water Supplies," Volume I, July, 1961, indicates that in addition to the
above-mentioned irrigable land, there are some potential 60,000 to 70,000 acres
within the Shuswap River valley between Sugar Lake and Mara Lake which might
be irrigated from the main river or its tributaries.
At present an investigation is under way to determine if any modifications would
be required for Scheme 3 to ensure that an adequate water supply is available to
serve these lands and to meet the future domestic, waterworks, and industrial water
requirements in the Shuswap River valley.
FoUowing this it is planned to extend the studies to other lands in the South
Thompson River watershed. The effect of the canal diversion on those areas which
in the future will be served by pumping from Shuswap Lake will be negligible since
even under the most extreme drought the reduction in inflow under Scheme 3 is only
some 6.5 per cent of the total lake inflow. Finally, for those areas between Shuswap
Lake and Kamloops, the modifications in the South Thompson flows from the canal
diversion will hardly be measurable. Further to this, the daily minimum flow of
the South Thompson at Kamloops is about 1,600 cubic feet per second, while that
of the North Thompson is approximately 1,300 cubic feet per second, both of which
occur in the winter at a time when the canal would not be in operation and Mabel
Lake would be at its lowest elevation.
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) irrigation and domestic water-supply projects, and
(b) flood- and erosion-control and drainage projects.
During the past year, investigations were continued or initiated on 13 water-
supply projects, and nine flood- and erosion-control projects. Of these, construction
was initiated or continued on five under the ARDA programme, involving the preparation by this Division of final design, including contract documents.
Technical staff attached to the Division were responsible for field surveys for
both the obtaining of engineering data and the layout of design, and the supervision
of construction.
The main projects dealt with in 1967 are summarized below.
Irrigation and Domestic Water-supply Projects
Black Mountain Irrigation District
A report prepared in 1965 by the Water Investigations Branch outlined a
scheme to rehabilitate the Black Mountain Irrigation District's works by constructing
a combined irrigation and domestic water-supply system to replace the existing open
flume and ditch system. This system was to supply water under pressure to some
4,550 acres and 530 farm domestic connections from the proposed Gopher Flats
reservoir, supplied from Mission Creek through 3.5 miles of open canal.   The esti-
mated capital cost of the project was $3,030,000, for which the district requested
ARDA assistance and received approval in October, 1966. The district subsequently expressed concern over possible contamination of its water supply in the
3.5 miles of open canal, and of probable algas problems associated with the Gopher
Flats reservoir. An alternative scheme was therefore investigated, and a new report
was prepared in August, 1967, proposing the construction of a large settling-basin
at the creek intake and the covering of the main canal from the creek to the point
of diversion for the distribution system. The revised scheme, which effected considerable changes in the distribution-system layout, provided for higher operating
pressures and a larger peak carrying capacity. The larger capacity was required
following reassessment of irrigation requirements for the area by the British Columbia Department of Agriculture. The amended scheme, capital costs of which remain
unchanged, has been accepted by the district and approved by ARDA authorities.
Approximately four years will be required to complete the project, which involves considerable improvements and repairs to the district's storage and diversion
works, as well as construction of the settling-basin and distribution system. The
latter will require over 40 miles of pipe-line in sizes from 4- to 42-inch diameter,
several pressure-reducing stations, three pumphouses, and a main-line chlorinator
and metering-station. Domestic and irrigation water will be provided from the
intake on Mission Creek, with emergency or stand-by winter domestic supply from
two wells in the Rutland area.
Construction will be carried out largely by the district's forces. Clearing and
stripping of the silting-basin site commenced in November, 1967, and the construction of the basin and intake works will be completed in the 1968 season. Tenders
have been called for the supply of pipe required for construction of the first phase
of the distribution system in the Rutland Flats area, which will begin early in 1968.
Black Sage Irrigation District
The Black Sage Irrigation District consists of 175 acres of irrigable land and
is situated on the east side of the Okanagan Valley approximately 3 miles south of
In 1965 a study was made of the distribution system following a request from
the district for ARDA assistance. Distribution system was replaced in 1966. In
1967 the district installed a new 100-horsepower electric motor and carried out other
improvements to the pumphouse, including the intake on an oxbow of Okanagan
Village of Lillooet
Following a request from the Village Commission, the problem of sediment in
the water-supply system of the Village of Lillooet was investigated.
The present source of water supply for the village is Town Creek, which originates in mountains west of the village, which rise to an elevation of 8,000 feet. The
intake for the waterworks system is situated about 3,000 feet upstream from the
townsite. From a point approximately 150 feet above the intake, and extending
upstream a further 250 feet, the left bank consists of glacial till approximately 200
feet in height. During the spring run-off when the bank is saturated from snow-melt,
slide material is deposited in the creek-bed and thence into the water system.
To improve the water quality, it is proposed to enclose Town Creek in a culvert
through the slide area and to construct a combined screening-box and settling-tank
at the present intake.
Naramata Irrigation District
The district receives water by gravity from Lequime (Chute), Robinson, and
Naramata Creeks. Storage has been developed in three reservoirs—Big Meadow
Dam on Lequime Creek, Naramata Lake Dam on Robinson Creek, and Eleanor
Lake Dam. Rehabilitation of the Naramata Lake Dam with increased storage and
reconstruction of a portion of the distribution system was approved under ARDA
programme. The Naramata Lake storage-dam project, designed by a consulting
engineer, was completed in 1967. Distribution-system rehabilitation was completed
in 1966.
However, during the summer of 1967 the district experienced a serious shortage
of water for irrigation purposes, and it has now requested that an engineering study
be carried out to consider additional water-storage possibilities.
Okanagan Mission Irrigation District
At the request of the district, an engineering study is currently in progress on
a combined irrigation and domestic water-supply system. The existing system, consisting of a pumping plant on Okanagan Lake, a main supply-line lying on the surface of the ground, and a distribution system consisting mainly of open flumes, is
no longer considered adequate to supply the area.
The proposed new system would supply some 360 acres of irrigable land and
a possible 370 domestic connections. The district has requested assistance under
the ARDA programme in financing the project.
Okanagan Falls Irrigation District
In July, 1967, the Okanagan Falls Irrigation District received approval to
carry out, under the ARDA programme, improvements and renewals to its combined irrigation and domestic water-supply system.
It is proposed to use ground-water wells to replace the present pumphouse and
intake on Skaha Lake. The feasibility of using ground-water was investigated by
the Groundwater Division of the Water Investigations Branch in 1966.
The proposed new works will include construction of a 40,000 U.S. gallon
reservoir, replacement of several pipe-lines, and the drilling of a test well which, if
successful, will be used to supply winter domestic water, and will be followed by
construction of a larger well to supply irrigation water. Should the test well prove
unsuccessful, the ground-water supply will be abandoned, and the district will
proceed with a second alternative of improving its existing pumps and intake and
constructing a booster station to supply the higher properties. Drilling of the test
well has commenced.
Because of the large non-agricultural domestic content of the project, the
district will contribute one-half of the total cost instead of the usual one-third
normally required under ARDA assistance programme.
Osoyoos Irrigation District
The construction of a new irrigation and domestic water-supply system for the
Osoyoos Irrigation District was completed in May, 1967, under the ARDA programme, approximately eight months after construction started. The new works
replace the old pumping and flume systems of the Osoyoos and East Osoyoos Irrigation Districts, which amalgamated under the name of the Osoyoos Irrigation District before the start of the project.

Pump intake line and screen being floated into position, Osoyoos Irrigation District.
The new system is supplying irrigation water to some 410 acres of land, mostly
in orchard, and domestic water to approximately 45 homes. The main pumping-
station, with four pumps totalling 370 horsepower, pumps water from Osoyoos Lake
to a 40,000-gallon reservoir 350 feet above lake-level. A 50-horsepower booster
station lifts water an additional 100 feet to irrigate the higher orchards in the district.
The main pumps are controlled automatically by levels in the reservoir.
The distribution system consists of about 5 miles of asbestos-cement pipe in
sizes of 4- to 16-inch diameter. All pipe-lines were laid by the district's crews.
Other work, including the pumphouse, was carried out under contract. Due to
high non-agricultural domestic water-supply content of the project, a portion of the
total cost was not eligible for ARDA assistance.
Peachland Irrigation District
Incorporated as an improvement district in 1920, the Peachland Irrigation
District took over an irrigation system laid out in 1906 by the Peachland Townsite
Company. The district is supplied by gravity water from Peachland (Deep) Creek,
augmented by diversion from MacDonald Creek and storage in Peachland Reservoir
No. 2, and Wilson Lake. Approximately 460 acres of orchards are presently under
In 1965 the district requested an engineering study to consider the feasibility
of a combined irrigation and domestic water-supply system under the ARDA programme. Field surveys were carried out in 1966, and subsequent mapping of the
district and storage reservoirs was completed in 1967. It is expected that a preliminary report will be completed by early 1968.
South East Kelowna Irrigation District
In connection with improvements being carried out to the distribution system
under the ARDA programme, the district requested a design for a proposed settling-
basin on the main diversion ditch from Klo (Canyon) Creek. During freshet
periods the creek carries a heavy bed-load of sand and silts, causing excessive wear
on irrigation equipment.
The proposed basin will accommodate a maximum design flow of 50 cubic feet
per second and will be approximately 250 feet in length, 70 feet in width, and will
be asphalt-lined. A junction box at the inlet end will allow the water to be diverted
into the pond for settling during the freshet period, or diverted through the existing
ditch when settling is no longer required. It is expected that the basin will be
constructed prior to the 1968 irrigation season.
Westbank Irrigation District
The Westbank Irrigation District, which includes the townsite of Westbank,
presently supplies irrigation water to about 867 acres, out of a potential irrigable
area of approximately 1,000 acres within the existing farms of the district. Domestic
water is supplied through the irrigation system during the summer season, and by
cisterns during the winter. Water is received by gravity from Powers Creek and
Lambly Creek watersheds, with an intake on Powers Creek, about 6,000 feet upstream from the district boundary. Storage has been developed on Islaht (Horseshoe), Dobbin, West, Paynter, Jackpine, and Lambly (Bear) Lakes.
The construction of a concrete intake dam and settling-pond, and screening-
works, and the placing of 7,000 feet of 34-inch-diameter steel pipe-line, representing the first phase of rehabilitation of the district's works under the ARDA
programme, was completed in April, 1966.
The next phase of rehabilitation includes the replacement of the district's
distribution system, to provide a combined irrigation and farm domestic supply, and
the reconstruction of Lambly (Bear) Lake and Islaht (Horseshoe) Lake dams,
to provide additional storage. An additional 500 acres of cultivated farm lands,
adjacent to the district, will also be served from the new system. This area, consisting mostly of lands within the Powers Creek Water-users' Community, lies on the
south side of Powers Creek, and is presently being served by a gravity system with
an intake on Powers Creek, upstream from the district's new intake. With the
inclusion of these lands within the Westbank Irrigation District, approximately
1,500 acres of irrigable land will be supplied from the new system.
A preliminary report is now nearing completion, and the district will submit
the proposal to the ARDA authorities for approval under the assistance programme.
Winfield and Okanagan Centre Irrigation District
The irrigation and domestic system now operated by the Winfield and
Okanagan Centre Irrigation District was constructed in 1909 by a private company.
Incorporated in 1930, the district took over the distribution system in 1949 under
a purchase agreement. To provide additional irrigation supply over the original
entitlement of 1 acre-foot per acre from Vernon Creek, in 1931, the district
developed 2,445 acre-feet of storage in Crooked Lake, and in 1944 reconstructed
Swalwell Lake Dam to provide an additional 9,585 acre-feet of storage, to supply
approximately 1,900 acres of orchard land and about 300 domestic connections.
Following approval of a preliminary report prepared by the Water Rights
Branch in 1965 which recommended extensive replacements, the district applied
for and was granted assistance under the ARDA programme with a construction
period of three years.
The first phase of construction, comprising the rehabilitation of Swalwell and
Crooked Lake Dams, and the construction of an access road into the latter dam,
was completed in 1967. Additional work included the improvement of 4,000 feet
of diversion channel in Vernon Creek and the building of a new office.
Replacement of the distribution system commenced in July, 1967. Altogether,
there are 18 miles of distribution-system lines and 7 miles of main supply-line to be
laid. All work has been carried out by the district, using its own forces under
supervision of Water Resources Service staff.
Studies are continuing on the design of a new intake on Vernon Creek, to be
situated about a mile upstream from the existing intake. It is expected that the new
site will provide adequate storage for both settling and balancing.
Water-storage Reservoir Inventory
A programme of mapping major water-storage reservoirs in the Southern
Interior of the Province was initiated in 1964. Areas presently surveyed under this
programme include the Okanagan and Similkameen basins and the Kamloops and
Nicola areas. This information has assisted in the administration of water rights
and the carrying out of water-supply augmentation studies in the water-deficient
Reservoir maps are being prepared by photogrammetry and field surveys,
including the use of echo-sounding equipment to obtain sub-surface information.
Of the approximately 100 reservoirs presently developed in the Okanagan basin,
adequate information is available on 52, mapping is nearing completion on an
additional 10, and surveys and mapping are pending on 29. The remaining nine
reservoirs are considered to be too small to be included in this programme. The
mapping programme for the Similkameen basin, which includes about 11 existing
and potential reservoir-sites, is nearing completion.    This programme is to be
continued in 1968.
Flooding, Drainage, and Erosion Projects
Cowichan River Flooding and Erosion
For many years the periodic flooding of the Cowichan and Koksilah Rivers and
Cowichan Lake has been of concern to the Duncan area, and the communities
around Cowichan Lake—Village of Lake Cowichan, Youbou, Honeymoon Bay,
and Caycuse. In 1958 the Prairie Farm Rehabilitation Administration (P.F.R.A.),
Canada Department of Agriculture, prepared a report dealing mainly with the protection of the Indian reserve below Duncan. In 1959 the Water Rights Branch,
acting with a local committee, investigated the problems and compiled preliminary
hydrometric data.
Following the flood of January, 1961, the Water Investigations Branch carried
out field surveys and obtained additional hydrometric data. Additional surveys
were carried out in 1965/66, covering the Lower Cowichan and Koksilah River
valleys and Village of Lake Cowichan, and a preliminary report was completed in
early 1967 discussing economic and physical feasibility of several flood-control
The proposed works would protect all of the flood-plains in the Duncan area,
and the communities around Cowichan Lake, by dyking and channel improvements
on the Cowichan and Koksilah Rivers in the Duncan area and by lowering the outlet
of Cowichan Lake to protect the communities at a total estimated cost of $1,800,000.
The area to be protected around Cowichan Lake is mainly residential and industrial,
while the area around Duncan is mainly agricultural and amounts to some 3,200
acres. The preliminary report is presently being reviewed by the local governments
and other interested agencies.
Kent Municipal Drainage
In the summer of 1966 the Water Investigations Branch commenced a study
of drainage problems in certain areas of the District Municipality of Kent, with
particular attention to the bottom lands at Agassiz, Harrison Hot Springs, and
Harrison Mills, which are protected by dykes against flooding from the Fraser and
Harrison Rivers. This study was completed in the early part of 1967, and a report
is presently being reviewed by the Kent Municipality.
In all cases the floodgates that provide for gravity drainage through the dykes
appear large enough to remove the run-off from a 25-year design winter storm,
though repair work is required on the works at Hammersley Prairie. In the main
slough areas, weed control is recommended. Many of the secondary channels, however, could benefit from improved vertical alignment and, in some sections, enlarged
carrying capacity. Additional pumping capacity would be required at all stations
to prevent storm water from flooding the fields for long periods when high river-levels
prevent gravity drainage through the floodgates. At Harrison Mills the required
increase in pump capacity could be economically reduced by constructing intercepting ditches at the foot of Mount Woodside to carry hillside storm run-off to the Fraser
and Harrison Rivers outside the dyked lowlands.
Matsqui Prairie Drainage
In July, 1966, a request was received from the Municipality of Matsqui for
assistance under the ARDA programme to improve drainage in the Matsqui Prairie
section of the municipality.
Studies were carried out during the latter part of 1966 and the first half of
1967, and the various schemes suggested, with estimate of costs, were outlined in
a preliminary report. Of the three schemes studied, the most economical indicates
that additional pump capacity would be required at the mouth of Matsqui Slough
and McLennan Creek; gravity flow would be maintained throughout the length
of the main channels with dyking along sections of the main channels and 12 pump-
ing-stations would be installed on the tributary ditches. The estimated capital cost
for the McLennan Creek drainage system is $712,000, and for the Matsqui Slough
system $2,121,000, for a total capital cost of $2,833,000.
An economic study of benefits resulting from improved drainage is presently
being carried out by the Department of Agriculture.
Nicola-Coldwater Rivers Flooding and Erosion
Following a complaint from the Village of Merritt and previous complaints
from individual land-owners, an investigation was made of flooding and erosion
problems in the Nicola Valley, from Nicola Lake to Spences Bridge and along the
Coldwater River through Merritt.
> Field surveys, which were initiated in 1965, included underwater topography
at the outlet of Nicola Lake to consider storage possibilities, ground control for the
preparation of large-scale mapping from air photography, and river profiles and
sections for the design of channel improvements and dykes.
The investigation was completed in the latter part of 1967, and a preliminary
report is nearing completion. This report suggests that within the Village of Merritt
improvements to the Coldwater River would consist of dyking and bank protection,
and improvements to the Nicola River would consist of dyking and bank protection
plus the construction of two new channel sections and two highway bridges. For
the section of the Nicola River below Merritt, bank protection only for erosion is
The proposed improvements are presently being reviewed by the interested
Okanagan Flood-control Works Survey
In the summer of 1963 a survey was made to assess the existing condition of
the Okanagan River flood-control works, which were constructed jointly by the
Federal and Provincial Governments in 1952-58. Their studies were completed
in April, 1965.
Several modifications and improvements in the flood-control works were recommended. Extensive bank and channel-bottom protection was required to stabilize
the channel at high or design maximum flows. Modification or lowering of the
water-supply intake culverts was necessary in order to supply irrigation water when
water-flows in the channel are below 500 cubic feet per second. The present practice of raising water levels by means of rock weirs and stop-logs in the drop-structures
has resulted in channel erosion. Minor improvements included levelling of the
rock paving within the sills of the drop-structures, repairing or renewing the right-
of-way fencing and gates, and the control of brush and weeds along the channel.
A further survey was made in 1966 to up-date the survey of 1963, and to
include improvements carried out on the system subsequent to 1963 plus proposed
improvements for the period 1966/67. A new report entitled " Okanagan Flood
Control Works, 1963 Survey Revised 1967," has been completed. The total estimated cost of improvements is $875,000.
A supplementary study was made of the flooding of lands adjacent to Tugulnuit
Lake, which lies about 1 mile north-east of Oliver.    This study recommends a
Mountain Transect Meteorological Station, Beaufort Mountain Range, Vancouver Island.
pumping-station to alleviate the flooding caused by the interrelation of levels of
Okanagan River and underground seepage during high-water flows in the river. The
estimated cost of a pumping-station is $20,000.
Pemberton Valley Dyking District
Under the tripartite agreement among the Pemberton Valley Dyking District,
the Federal Government, and the Provincial Government, the Prairie Farm Rehabilitation Administration (P.F.R.A.), 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 high water. As a result, a request was received from the district for
assistance under the ARDA programme to further improve this 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 by installing a pumping-station 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.   The report is presently being reviewed by the dyking district.
Tsolum River Study
In November, 1966, a request for a study of the feasibility of flood- and
erosion-control and irrigation water supply was received from land-owners living
along the Tsolum River north of Courtenay. The study involves some 3,000 acres
of agricultural land along both banks of the river extending 10 miles upstream from
the river-mouth at Courtenay.
Field surveys have been completed, and office studies are nearing completion.
An examination of hydrometric records indicates that peak flows exceeding 8,000
cubic feet per second could occur during winter storms. Possibilities of upstream
storage to delay the effect of peak flows and at the same time provide water to
augment low summer flows in the Tsolum River for irrigation purposes are being
considered. The cost of river-bank protection is also being considered in the lower
5 miles of the river.
Miscellaneous Activities
Salmon River valley large-scale mapping programme, which was initiated in
1966, is continuing between Salmon Arm and Westwold.
A limited stream-gauging programme was undertaken near Abbotsford Village
in connection with a water-supply study for a proposed trout hatchery.
H. I. Hunter, Hydrometeorologist, Chief of Division
Included among the more important Hydrology Division responsibilities are the
following: Maintenance, new installations, and operation of the British Columbia
mountain snow-survey network; development of volumetric seasonal snow-melt and
daily stream-flow forecast procedures; publication of British Columbia Snow Survey
Bulletins; hydrometeorological data compilation; planning, installation, and operation of hydrological instrumentation at a pressure-pillow snow-measurement test-site
and at an International Hydrological Decade mountain transect project; operation
of instruments and interpretation of measurements obtained at an International
Hydrological Decade study basin; hydrology studies; computer programming for
not only the Hydrology Division, but also for other Water Investigations Branch
divisions and work associated with certain provincial, national, and international
committees involving hydrology.
Snow-course Network
During 1967 the British Columbia snow-course network continued its expansion with the installation of six new courses. These included Morfee Mountain on
Parsnip drainage, Germansen on Omineca, Tachek Creek and McKendrick Creek on
Fulton, Boss Mountain Mine on Clearwater, and Nahatlatch River on Lower Fraser
drainage, and all located at the request of co-operating agencies for use in predicting
future snow-melt water supply. The only deletion was the Labour Day Lake course
on Vancouver Island's Nanaimo River watershed. A total of 175 courses will be in
active operation in 1967/68 winter sampling season.
Using ski, snowshoe, over-snow machine, and helicopter transportation, technicians visited 30 snow courses last winter to provide at-site snow-sampling instruction, and as part of the regular summer maintenance work 49 existing courses were
cleaned and brushed.
Stream-flow Forecasting
Seven issues of the British Columbia Snow Survey Bulletin, which included the
February 1st, March 1st, April 1st, May 1st, May 15th, June 1st, and June 15th
publications, were distributed to some 700 interested individuals and agencies. As
well as showing build-up, maximum accumulation, and depletion of the Province's
1967 snow pack on a regional basis, these bulletins provided quantitative snow-melt
run-off volume forecasts for 31 gauging-stations on 17 rivers and a written assessment of potential flooding for Interior rivers.
Extremely heavy snow packs were measured at mountain snow courses throughout the winter and late spring of 1967, resulting in flood-hazard warnings for low-
lying areas along the Kootenay, Columbia, and Fraser Rivers. Although relatively
high stages did occur on these rivers, ideal weather conditions prevailed during the
critical snow-melt period to alleviate the flood hazard and produce a naturally controlled run-off. Considerable time was spent during May, June, and early July in
analysing hydrographs and climatic data to provide estimates of expected river stages
which were required in connection with emergency flood-control planning.
Immediately following the freshet period, the Southern Interior experienced, in
July, August, and September, one of, if not the warmest and driest summers of
record, resulting in much higher than usual evapotranspiration losses. The Okanagan
region in particular suffered from this prolonged hot dry spell, with evaporation from
Okanagan Lake the highest of record. Even with a controlled reduced outflow, a
steady decline of lake-level occurred throughout this period.
In July an investigation of the hydrological factors affecting the Fraser River
system was begun. The objective of this investigation is to provide improved operational methods for both seasonal volume run-off and daily run-off forecasting for
use in water-resource management and flood-control operation. To date, stream-
flow and precipitation records have been checked for consistency, missing data have
been estimated, and statistical forecasting methods started.
The electronic computer was used to develop new, and up-date old, stream-flow
forecast procedures by regression analyses. New computer programmes were written to provide the following: (1) Selected station listing of accumulated annual
run-off in acre-feet for varying time periods of the historical record; (2) selected
station listing of annual and seasonal run-off in inches and cubic feet per second per
square mile for the historical record; (3) listings for a snow-course operational chart
and a snow-course sampling reminder schedule; (4) a backwater analysis for use
on the Squamish and Mamquam Rivers; and (5) a hydraulic gradient analysis for
use on the Vernon Irrigation District project. In order to familiarize himself with
the necessary technology for conversion to the new I.B.M. 360 system, the Division's
programmer-analyst has attended several I.B.M. courses.
Hydrological Studies
A complete year's record of measurements has now been obtained on the International Hydrological Decade representative basin near Carrs Landing on the
Okanagan Lake watershed. The data from this 4-square-mile basin will be used
to study the hydrological cycle and to provide indices for forecasting inflow to
Okanagan Lake. Up-to-date graphical plots of evaporation, soil moisture, groundwater, temperature, precipitation, wind, humidity, and snow-course data have been
compiled for the various sites with intercorrelation plots completed between sites.
A preliminary study using Penman, Thornwaite, and Evaporimeter methods has
been completed, with monthly estimates derived for Okanagan Lake evaporation
and mean basin potential evapotranspiration.
A second International Hydrological Decade project, with the Federal Meteorological Branch as a co-operator, was initiated on the Beaufort Mountain Range on
Vancouver Island. Its objective is to assess the effect of topographic parameters,
particularly elevation, on precipitation and temperature distribution on both windward and leeward sides of a mountain range. The general plan calls for installation
of monthly recording precipitation and temperature instruments at selected elevations on two adjoining transects. From the basic data collected, it is hoped that
distribution techniques and relationships can be developed for use in other mountainous areas of British Columbia. This past summer, stations were established at
the 1,500- and 2,800-foot levels of the west-facing slope and at the 4,500-foot
summit of the first transect. Measurements are now being collected from these
The pressure-pillow test-site at the 6,300-foot level on Blackwall Mountain in
Manning Park provided snow-water equivalent, precipitation, and temperature
measurements. Unfortunately, after a satisfactory operation of five months and
with a water equivalent reading of 30.5 inches, the Kirkhill pillow developed a leak,
resulting in subsequent erratic readings. This pillow has now been replaced with
the newly developed and more durable Goodyear pillow, with the hope that satisfactory readings will be obtained this coming winter. The Kirkhill pillow was patched
and located at a meteorological station on the Vancouver Island mountain transect
project. Graphical plots have been made of all measurements collected at the
Blackwall test-site.
Hydrometeorological Data Compilation
Requests for stream-flow, meteorological, and snow-course data by Water
Resources Service engineers and technicians are becoming more frequent, and if the
information is not available in the Division's library, it is obtained from the appropriate basic data-collection agency. Under a cost-sharing agreement with the Federal
Inland Waters Branch, an assessment is made each year with respect to existing and
proposed hydrometric stations. For the calendar year 1967, 28 all-year stations
were established, 13 re-established, and 10 discontinued. Partial or irrigation station
measurements were completed on 94 streams by the Federal Inland Waters Branch.
A quality check was made of the 1967 snow-course measurements, incorporated
with past measurements, and then listed by I.B.M. equipment with new statistics
derived from this data.
The Chief of the Division is a member of several working committees, including the Western Snow Conference Executive Committee, National Research Council
Sub-committee on Hydrology, British Columbia Hydrometeorological Networks
Co-ordinating Committee, ARDA Agro-climatology Committee, and the Columbia
Basin Forecast Committee.
A paper entitled " Streamflow Forecasting in Mountainous British Columbia "
was prepared by the Chief of Division for the International Conference on " Water
for Peace." Mr. C. H. Coulson, Hydraulic Engineer, attended a three-week
hydrology course at the University of Guelph.

Water-well Inventory
Data on existing water wells and ground-water use continues to be collected by
field reconnaissance and through co-operation with governmental agencies and well-
drilling contractors and is being compiled on cards and well-location maps. The
main project in 1967 was a water-well inventory in the area from 70 Mile House,
Cariboo Highway, to Prince George and west to Vanderhoof. A well inventory was
also carried out on the Sechelt Peninsula.
Water-well Maps
A total of 12 new water-well maps was compiled during the year. In addition,
an index was completed showing the locations of completed water-well maps. The
new maps cover areas in Osoyoos, Kootenay, New Westminster, Range 4 Coast, and
Similkameen Districts.   Two maps covering North Saanich District were revised.
Observation Wells
Data continued to be collected and recorded on existing observation wells. Ten
new observation wells have been added to our existing network. Five observation
wells, four of them with screens and 6-inch casing, were completed in the Interior
of the Province at Keremeos, Beaverdell, Stump Lake, and Clinton. The fifth
observation well was drilled in bedrock at Lone Butte. The observation well at
Keremeos is equipped with a pressure recorder.
Two 6-inch-diameter high-altitude observation wells have been completed in
bedrock near Barkerville at elevations of approximately 5,000 and 4,950 feet; two
6-inch-diameter observation wells have also been installed north-west of the Morfee
Lakes at altitudes of approximately 4,750 and 3,900 feet.
A 500-foot-deep 8-inch test-well drilled into bedrock lava flows near Eighty-
three Mile Creek on the Cariboo Highway is being used as an observation well. Two
observation wells using small-diameter plastic casings have been successfully constructed in rotary test-holes recently completed at Williams Lake.

A test-well completed this year near Fry's Corner, north of Cloverdale, is now
being used as an observation well within the Lower Fraser Valley network.
Further improvements have been made by the staff of the Groundwater Division on the design and construction of a water-level recorder using compressed air.
Three of these instruments, although still experimental, have been installed in the
Lower Fraser Valley on three small-diameter observation wells where the standard
model recorders cannot be used.
A water level-water temperature electric recorder, valuable for use with small-
diameter observation wells, is at present under construction.

Two wells were lost during the year, one located in the Lower Fraser Valley,
the other in the North Okanagan.
Hydrologic Basin Study near Okanagan Lake
Work on this project continues in co-operation with the Hydrology Division.
Details of this work are recorded in the Hydrology Division's report.
Exploratory Water-well Drilling
Lower Fraser Valley
Development and testing were completed on a test-well constructed north of
Fry's Corner in the Serpentine Valley, north of Cloverdale, in connection with a
large-scale irrigation proposal. Severe well-construction problems were encountered
in the artesian aquifer during construction the previous year. The results of the
well-testing were not encouraging and appeared to indicate that present methods of
well construction are not adequate for the special conditions encountered in this
water-bearing formation.
North Okanagan Valley near Armstrong
Exploratory well drilling and test pumping continued in limited areas to obtain
further information on ground-water potential. A test-hole, 907 feet deep, cased
with light-wall 16-inch-diameter pipe, was completed along with a high-capacity
water well 606 feet deep near Armstrong in the North Okanagan Valley. Both
test-hole and test-well were drilled by the reverse circulation cable-tool method.
Due to the very fine material encountered during drilling, the test-well was
gravel-packed around a 300-foot length of inexpensive screen made up of steel
with louvre-type slots. The well was test-pumped at 335 imperial gallons per
minute for a drawdown in the well of 9 feet. Well records on the files of the
Groundwater Division have shown that drilling contractors using more conventional
well-drilling and well-construction techniques had previously not been able to construct high-capacity wells in this area.
Test-well at Mile 80, Cariboo Highway
A test-well was drilled during May and early June by cable-tool methods, 500
feet deep, into Tertiary lava flows of the Cariboo Plateau. Pumping-test results
were encouraging and indicated that the well has a high capacity.
Southern Okanagan Lands Irrigation District
Three shallow test-wells were drilled for ground-water information south of
Osoyoos within the Southern Okanagan Lands Irrigation District. Only one test-well
was completed with a screen and pump-tested. Further test drilling is planned for
a higher-capacity well.
Keremeos Irrigation District
Under guidance from the Groundwater Division, well drilling on the Keremeos
Irrigation District rehabilitation project continues in co-operation with the ARDA
Projects Division.
Two test-wells and two production wells have so far been completed for the
Keremeos Irrigation District. The first test-hole was drilled to 412 feet, and test-
screens were set in turn at three different depths and pump-tested. A second test-
well was subsequently completed and pump-tested. The tests showed that the construction of high-capacity production wells are feasible near Keremeos.
Two large production wells have now been completed and pump-tested at 1,500
U.S. gallons per minute.   Two additional wells are at present under construction.
Okanagan Falls Irrigation District
A test-well is being drilled at Okanagan Falls under guidance from the Groundwater Division, and if the well is successful, a high-capacity production well will be
drilled for irrigation purposes in connection with Okanagan Falls Irrigation District
rehabilitation project under ARDA programme.
Ground-water Research Project at Prince George under ARDA Programme
Under supervision of the Groundwater Division, work continued on this project.
Four test-wells were drilled with cable-tool equipment during the year. Pumping
tests were also carried out.   A report on this research project is being prepared.
Exploratory Rotary Test-hole Drilling
As a follow-up to a ground-water investigation which was commenced in the
Cariboo area last summer, five rotary test-holes were drilled in the Williams Lake
area. The aim of this rotary test-drilling programme was to find out if there existed
in the Williams Lake valley sufficient deposits of sands and gravels which could be
considered for more detailed test-well drilling and ground-water development.
The information obtained from this test-hole programme is now being assessed.
The Groundwater Division used improved rotary drilling techniques and drilling
fluids, which enabled the test-hole to be drilled deeper and to stay open in more
unconsolidated material. One test-hole at the west end of Williams Lake was drilled
down to a depth of 600 feet.
Miscellaneous Field Investigations and Office Studies
A ground-water investigation was commenced in the Cariboo area this summer
and included a geological investigation of surficial deposits, a well inventory of the
area, and ground-water test drilling.
A limited programme of geological mapping was undertaken in the Campbell
River area to obtain information on the nature and distribution of surficial deposits
and on the ground-water potential.
A well was drilled under our guidance by the Department of Public Works in
connection with a problem of water supply for the Fraser Valley Trout Hatchery
near Abbotsford. The results of the pumping test indicate that large production
wells may be possible in this aquifer but further test drilling will be required.
Advice was furnished to the Municipality of Sumas concerning location of production wells for the municipality. A brief field investigation was also made to locate
a well-site.
The British Columbia Forest Service carried out a programme of rotary test
drilling, under the guidance of the Groundwater Division, at localities 7 miles northwest of Campbell River, Vancouver Island, and near Langley.
A brief investigation for a small source of ground-water was made to the
Southey Point area at the north-west tip of Saltspring Island.
A short investigation was made, at the request of local residents, in the McCoy
Lake area near Alberni in order to assess the ground-water possibilities in the area.
Advice was given to the University of Victoria on drilling a well on the university campus to supply ground-water needed for aquaria studies.
Other requests for information or assistance include the following: Parks
Branch, Department of Recreation and Conservation—information on ground-water

This Division of the Water Investigations Branch has two main functions: (1)
development of plans for water management on a regional or watershed basis, with
an immediate aim to indicate the feasibility of improving the dependability of surface-
water supplies in areas where readily available water supplies have been exhausted,
and (2) continuation of inventory of undeveloped water-power potential of the
The following work has been done during the past year.
Water-management Studies
Nicola Basin
A study on Nicola Lake inflow and regulation was completed. This study considers the hydrology of the 1,100-square-mile drainage area tributary to Nicola Lake
with special reference to actual net inflow to the lake and lake control for irrigation
EE 71
or other purposes.   The history of lake-level control was traced from construction
of the first dam in 1927 to the present day.
From actual records and a series of correlations, an estimate was made of the
potential of Nicola Lake for regulation within narrow limits of storage depth. As
a maximum it is estimated that a storage depth of 7 feet would yield a storage of
40,000 acre-feet and provide water for 19,000 acres of irrigable land while leaving
50 per cent of regulated flow yield for other purposes.
Nicola-Kamloops Area
Under an agreement between the Civil Engineering Department of the University of British Columbia and the British Columbia Water Resources Service, it is
proposed to carry out a water-resources planning study of the Nicola-Kamloops
area, encompassing some 3,800 square miles. It is expected that the study will
take several years to complete, will be multi-discipline in character, and will consider
the many social and economic factors influencing the future development and land
uses in the area.   Basic data compilation for this study was commenced.
Creston Area
A preliminary report was prepared on the economic feasibility of supplying
irrigation and domestic water to the Alice Siding area, north of Creston, in connection with a request under Federal-Provincial assistance programme.
Storage-regulation Curves
Extensive analysis was made of available long-term hydrometric records for
eight stations considered representative of the Coast, Northern Interior, and Southeast Interior regions. Analyses produced differential mass curves, which were used
to construct storage-regulation curves characteristic of the different climatic regions.
This work is of value to those interested in the probable behaviour pattern of rivers
in these areas.
An estimate is being prepared of possible irrigable areas in British Columbia
using contours as the main guide and based on subdivision watersheds, each exceeding 1,000 square miles in area.
An investigation has been made of a proposal to dam Tutshi Lake, near the
British Columbia-Yukon Territory Border, and to divert water therefrom for a
hydro-power development.
A preliminary examination was made of the water-yield potential of the Chemainus, Cowichan, and Koksilah River valleys, including storage possibilities and
ground-water sources.
An investigation is being made to determine whether the yield from the Naramata Irrigation District watershed is sufficient to warrant an increase in storage
capacity of the present reservoirs.
Hydro-power Investigations
Liard River
From January 22nd to May 6th a preliminary sub-surface drilling programme
was carried out under the supervision of Dolmage, Campbell and Associates, Consulting Geologists, at Site A, 30 miles upstream from the mouth of the Fort Nelson
River, in order to determine the depth of gravel in the river-bed and the competence
of the underlying rocks for the foundation of a high dam.   The contractor, Canadian
Longyear Ltd., drilled eight vertical NX diamond-drill core holes comprising a total
of 2,472 feet, of which 699 feet were in overburden and 1,773 feet were in sedimentary bedrock. Five of the holes were drilled from the river ice and three holes were
drilled in the abutments. Severe cold weather in February hindered the work, when
the temperature fell to —55° F. This exploration revealed that an earth-fill dam
of medium height can be founded on the rock at Site A.
Using a helicopter, an inspection was made by the consulting geologist of the
Liard River from Site A upstream to Site J, 12 miles upstream from Liard Crossing.
A search for gravel fill for a dam at Site A showed that the only likely source would
be the river-bed. Examination of the stability of the river banks upstream from
Site A indicated no major problems affecting trie safety of a dam at Site A. A preliminary inspection was made of gravel exposures and the sedimentary-rock outcrops
at Site E, 14 miles downstream from Liard Crossing. It was considered that an
earth-fill dam at least 370 feet high can safely be founded on the bedrock at Site E
and that there is an ample source of fill in nearby gravel terraces.
Tenders have been called for a contract for sub-surface drilling early in 1968
at Site G, 11 miles upstream from the confluence with the Kechika River.
Office studies of the power potential of the Liard River Basin are continuing.
The preparation of new topographic mapping of the Liard River and its tributaries, the Fort Nelson and Kechika Rivers, is being continued by the Surveys and
Mapping Branch of the Lands Service for use in these power studies.

J. D. C. Fuller, P.Eng., Construction Engineer
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 Division
is also responsible for the design and construction supervision of certain approved
projects. The British Columbia Department of Agriculture is charged with the
over-all administration of the ARDA programme. Under an interdepartmental cooperative arrangement, the British Columbia Water Resources Service is responsible
for implementation of ARDA water projects.
Since the inception of the ARDA programme, many of the requests for assistance have been approved and successfully completed, while others are in various
stages of construction. In some instances, especially where construction has been
carried out by contract, supplementary assistance has been requested to cover rising
costs and complete the projects.
Since 1963, when the ARDA water-projects programme got under way in British Columbia, a total expenditure of $22,000,000 has been authorized and some
$8,400,000 actually expended in various ARDA water projects.
Actual and potential water projects under the ARDA programme total 75 in
number, and, of these, 46 have requested or received assistance, 22 are under study
prior to a proposal submission, and seven are in abeyance for various reasons.
Provincial and Federal authorities have approved 44 proposals to date, and
18 of these have been completed, leaving 23 presently under construction and three
in the final design stage.
Of the projects still in progress, six were brought into operation and may be
considered complete in the construction sense. The 20 incomplete projects are
multi-year programmes, some of which may not be completed until 1970.
Some of the 18 completed projects have still to submit final claims for reimbursement in respect of such items as contractors' holdbacks and legal or survey
costs pending.
It will be unnecessary to describe each of the 75 projects as 31 of them were
outlined in the 1966 Annual Report and others in the Reports of 1965 and 1964.
The task would in any case be voluminous, and only those projects where significant
changes have taken place will therefore be referred to this year.
Engineering services for the listed projects are being provided by the Water
Investigations Branch and by the Water Rights Branch, as well as by consulting

and 29009(S).—A pumping plant was rebuilt and placed in service on the distribution system completed the previous year.
Projects under Construction or Study
6. Southern Okanagan Lands Irrigation District Rehabilitation—ARDA Project No. 10010.—The basic purpose of this project is to rehabilitate the existing irrigation water-supply system of the Southern Okanagan Lands Project. New works
involved are being constructed over a period of six years. Stages One and Two
were completed in 1965 and 1966 respectively. The th'rd stage was the construction
of new pipe-line system and pumping facilities to areas designated as Pump Systems
No. 8 and No. 7. These works were completed and brought into operation at
the beginning of the 1967 irrigation season. Pump System No. 8 receives water
from Osoyoos Lake, utilizing 650 horsepower to provide domestic and irrigation
water to 850 acres. Pump System No. 7 receives water from the existing irrigation
canal and utilizes 150 horsepower to provide irrigation water to 490 acres. The
existing canal was terminated immediately downstream of Pumphouse No. 7, and
the necessary spillway leading to the valley bottom was constructed.
The fourth stage, Pump Systems Nos. 4 and 6, was designed early in the year,
and construction on Pump System No. 4 started during the late summer. This stage
will supply 1,400 acres through two pumping-stations of total capacity of 650 horsepower situated on the main canal.
Detailed studies of the main canal system were made, and designs for three

By May, 1967, two major branch lines with booster pumping-stations were
ready for the 1967 irrigation season. These serve some 1,000 of the district's area
of nearly 10,000 irrigated acres.
Flow records and pressure tests taken over the season indicate that operation
of this section of the system is satisfactory. Total water used (1.48 acre-feet per
acre) was 103 per cent of that assumed for design, and peak flow rate (4.3 U.S.
gallons per minute per acre) 86 per cent of the design figure.
Construction completed up to December includes the following works:—
(1) Installation of pipe under 24-inch diameter, 109,000 feet (33 per cent of
(2) Installation of pipe of 24-inch diameter and over, 22,000 feet (18 per cent

North and West Vancouver Flood-control Project
The completion of the Mosquito Creek improvements early in 1967 and the
Capilano River bank-protection work in 1966 fulfils the District of North Vancouver
component of the Federal-Provincial agreement of February, 1966, under the
Canada Water Conservation Assistance Act, providing for the construction of channel improvements on streams in North and West Vancouver for flood- and erosion-
control purposes. The Greater Vancouver Sewerage and Drainage District, acting
as agent for the District of West Vancouver, is preparing further proposals involving
control of four creeks in West Vancouver.
To date some $600,000 has been expended under the agreement out of a total
estimated cost of $2,301,480, to be shared by Canada (37Vf_ per cent), the Province
of British Columbia (37Vi per cent), and the local authorities (25 per cent).
Hastings Creek Flood-control Project
Following signing of an agreement between Canada and the Province of British
Columbia in late 1966 under the Canada Water Conservation Assistance Act, the
Province entered into an agreement on April 10, 1967, with the Greater Vancouver
Sewerage and Drainage District, agent for The Corporation of the District of North
Vancouver, for the construction of tributary diversion-works on Hastings Creek.
This project involves the installation and construction of some 7,500 feet of
reinforced-concrete pipe and culvert to intercept and collect the several branches
of Hastings Creek and divert to Lynn Creek, eliminating the flooding of land and
residences below Kilmer Road and allowing a more efficient and orderly development of the area. Final plans and estimates of costs have been submitted and are
under review.
Alberni Flood-control Project
The Alberni flood-control proposals provide for flood control in the west
section of the former City of Alberni against high tides in the Somass River and high
discharge in Kitsuksis Creek. The design of the River Road section of the project
and the channelization of Kitsuksis Creek were prepared for the Water Resources
Service by the Department of Highways, and consultants were retained for the design
of the interceptor sewer and pumping-station. Final drawings and specifications are
complete. The question of right-of-way for the section of River Road crossing
Indian land is under discussion with the Federal Indian Affairs Branch.
A revised agreement between Canada and the Province of British Columbia
under the Canada-British Columbia Joint Development Act and the Canada Water
Conservation Assistance Act to implement the project is expected in the near future.
The estimated cost of construction is in the neighbourhood of $1,000,000.
Lower Fraser Valley
Following completion and submission of the Federal-Provincial committee
report entitled "An Assessment of Dyke Reconstruction, Drainage Improvements
and River Bank Stabilization in the Lower Fraser Valley " in 1966, work has continued on the collection and up-dating of data, including maps, dyke profiles, and
details of pump installations for the dyke and drainage systems in the valley.
The heavy snow pack experienced throughout the Province this year, with the
possibility of flooding in the Lower Fraser Valley, necessitated a programme of dyke
inspection. In this connection, some 3,400 feet of new dyke was constructed across
Coquitlam Indian Reserve No. 2, linking the Colony Farm dykes to the Coquitlam
River dykes at the Red River Bridge.
At the request of the Municipality of Chilliwhack, a start has been made on
an assessment of the drainage systems within the municipality. Several temporary
staff gauges have been installed on streams and ditches to assist in establishing
rainfall-runoff relationships.
A proposed drainage and pumping system to alleviate flooding of agricultural
land in the Municipality of Surrey in the vicinity of Halls Prairie Road is being
Lower Squamish Valley Flood- and Erosion-control Project
In 1965 the Province submitted a flood- and erosion-control proposal for the
Lower Squamish Valley under the Canada Water Conservation Assistance Act, and
in October, 1966, a joint committee of Federal and Provincial engineers was appointed to study and report on the proposals. The committee has now submitted
its report to both Governments, including an assessment of the costs and benefits
for various levels of protection.
Kitimat River
At the request of the District of Kitimat, flood problems associated with high
winter discharges in the Kitimat River are under investigation.
After a preliminary field investigation, arrangements were made with the District of Kitimat to co-operate with the Water Investigations Branch in obtaining field
data, including high-water profiles and river cross-sections. The Branch has also
arranged for large-scale mapping of the area.
Other Projects
As a result of complaints by land-owners in the Bulkley Valley regarding flooding and erosion along the Bulkley River, a preliminary field assessment of the magnitude of the problem was undertaken. An office study of the hydrology of the
drainage basin has been started, and it is anticipated that further investigations will
be made when low-level air photography becomes available next year.
A drainage problem in the Village of Abbotsford was reviewed for the Department of Highways.
During the year a number of complaints regarding local flooding and erosion
problems were investigated, and in five instances assistance in the design, supervision
of construction, and financing was given by the Water Resources Service within the
available limited budget.
Stellako River
The Federal-Provincial technical sub-committee appointed to study the 1967
log drive on the Stellako River held a number of meetings during the year and
arranged for co-operative investigation by the various agencies involved. Field work
was undertaken before, during, and after the log drive to collect data on the various
aspects of the problem. The British Columbia Research Council has been retained
as adviser to the Water Resources Service.

requests for over 100 copies of other publications, including interlibrary loans, were
researched and completed by the staff. The year under review also saw an increase
in the circulation of periodicals and technical literature. Of the present total of
1,450 reports in the library, 868 reports have been prepared by the Water Resources
Service staff. The following table shows the number of such reports and the general fields which they cover:—

Uncontrolled mosaics made       3
The up-dating of the map, charts, and graphs for six Snow Survey
Bulletins and up-dating the snow-course map and the reservoir
chart for the Hydrology Division was also carried out.
The drawings were produced to satisfy the requirements of a total of 49 projects. Of that number, 34 were engineering reports, seven were construction projects,
and eight were technical studies in which no formal drawings were produced.
Of the 49 projects in which the draughtsmen were involved in 1967, at least
15 will be continued or amended in 1968.

Inspector of Dykes
The spring Snow Survey Bulletins issued by the Hydrology Division of the
Department gave warning that this year's freshet would be of above normal proportions and that a larger than usual potential flood threat to the valley dyked areas
As a result, finances with which to undertake flood-preventive projects were
made available to the Department. This Division was in turn asked to provide
a listing of recommended dyke-improvement projects for valley dykes that would
be possible of completion in the short time remaining prior to the freshet.

in the just over two-month period extending from early April until mid-June. This
placed a large demand on trucks, gravel-loaders, and similar equipment in the Fraser
Valley, and almost all available equipment was utilized.
It was also not possible for the small permanent establishment of our Division
to give proper supervision to so many widely separated projects. The Department,
therefore, allocated personnel from other branches to give supervision to some
specific projects, and as well made arrangements with the Department of Highways
whereby that Department would accept a large measure of responsibility for some
of the dyking projects, notably those of Barnston Island, Maple Ridge-Pitt Meadows,
and the two Coquitlam projects, in addition to work carried out on Deas Island and
at Albion.
This assistance is gratefully acknowledged at this time.
The year's freshet was of longer than average duration, and peak levels were
well above average. The Fraser River gauge at Mission remained above the 20-foot
level from June 6th to July 4th, inclusive, with the peak level of 22.71 feet being
registered on June 22nd. This peak level was approximately 2 feet below the
damaging flood level of 1948, and all dykes were able to contain this peak flow
without damage.
Normal work was carried out in all districts in the remainder of the year.
Total expenditure on river-bank protection work was approximately $280,000, this
being approximately the same expenditure as was made in 1966.

The administration of the Southern Okanagan Lands Project is a responsibility
of the Water Resources Service, and the operation of the irrigation system will continue to be a major activity until the current rehabilitation programme being carried
out as an ARDA scheme is completed in about three years' time. When the existing
gravity system has been converted to a pressure system, it will be turned over to
the Southern Okanagan Lands Irrigation District, which is an improvement district
already formed to operate the system.
Following the change to pressure distribution, there has been some public
interest in the bench lands west of the canal right-of-way for agricultural purposes.
In October three large lots amounting in all to 192 acres in the Hester Creek area
were sold by public tender for apple and grape culture.
When the Okanagan flood-control channel was constructed, numerous small
pieces of land and old river oxbows remained as portions of District Lot 2450 (S.)
or had been acquired from private ownership to facilitate construction. Over 100
of these were examined, and many were offered for sale to adjoining land-owners.
A number of pieces have been sold, and others will be disposed of when lot boundary
problems are resolved.
The irrigation season commenced when water was turned into the main canal
on April 24th, and all pumps went into operation shortly thereafter. Although the
summer was extremely warm, and some difficulties were encountered in one of the
pump systems, the over-all system functioned satisfactorily through until September
29th, when water was turned off and all irrigation pumps closed down.
The usual ditch-riding service was provided for the Black Sage and Osoyoos
Irrigation Districts. Normal maintenance of the Southern Okanagan Lands Project
canal was carried out during the early spring, and a dormant copper sulphate spray
was applied to the canal in April to retard aquatic and alga, growth.
Construction continued on the rehabilitation of the system, and Pump Systems
Nos. 7 and 8 were put into operation at the start of the irrigation season. During
the balance of the year, work was largely directed toward the installation of Pump
System No. 4, while Dole valves were placed in suitable locations in Pump System
No. 9 to alleviate overuse of water.

Personnel Officer
In 1967 the permanent establishment of the Department was increased by seven
positions. All of these positions were for the Pollution Control Branch and included
one clerk-typist, two technicians, three engineers, and one analyst. Staff in this
Division now totals 15.   All positions except the analyst have been filled.
Early in 1967 there was an acute shortage of professional engineers. While
on an overseas trip, the Deputy Minister interviewed a number of interested candidates. Of these, two have, or soon will, join our staff. The latter part of 1967,
however, saw a change in the supply of engineers. This would appear to be due
to an increased number of professional people immigrating and a movement of
engineers from Eastern Canada. At the present time, only two vacancies exist for
The table below summarizes personnel activities for 1967 and the three previous

The turnover rate remained the same as 1965 and 1966, but an increase is
noted in the number of hirings of permanent staff and short-term casual staff and

Revenue and expenditure accounting and records for the Water Resources Service are maintained by the Lands and Water Resources Accounting Division. With
the fairly rapid expansion of Water Resources Service over the past few years, the
Accounting Division has had to direct more and more of its resources, particularly
in respect of expenditure, toward this department. Three years ago it was necessary
to increase the establishment by one clerk in order to deal with the increasing work
load. Since then every effort has been made to improve procedures and eliminate
unnecessary steps and to maintain only those records that are considered essential
and necessary.
All figures of expenditure relating to Water Resources Service may be found in
the Public Accounts of the Province, tabulated on a fiscal-year basis. Such records
are not maintained on a calendar-year basis. As of December 31, 1967, there were
34 ARDA projects in operation, or for which final claims have not been made, and
three project agreements in hand under the Canada Water Conservation Assistance
Act, with several others under the latter authority being considered for approval.
Such shared-cost agreements increase the work of this Division. Expenditures in
all other phases of Water Resources Service have also increased considerably in
recent years.
With respect to revenue, the licensing accounts of Water Resources Service
have been on a data-processing system since 1953, and as new equipment became
available these records were placed on the more sophisticated machines. During
1967 the 21,300 water licence accounts were transferred from the I.B.M. 1620 system to the I.B.M. 360 computer. The operation of this equipment is under the
control of the Data Processing Centre, Department of Industrial Development,
Trade, and Commerce. All input data for the computer, with the exception of that
for power licences, is provided by the Accounting Division. The Data Centre provides the Accounting Division with weekly information up-dating the accounts.
Annual billings for all licences, except power, are prepared and mailed in
January of each year.   Power billings are usually mailed in April.

The Pollution Control Board was initially formed in 1956 under the administration of the
Minister of Municipal Affairs. On April 1, 1965, the Board was placed under the Minister of
Lands, Forests, and Water Resources, with the Deputy Minister of Water Resources acting as
The functions of the Pollution Control Board are set forth in the Pollution Control Act,
1967, as follows:—
" The Lieutenant-Governor in Council may direct the Board to inquire into, to determine
causes of and remedies for any matter or matters relating to the polluted conditions of water,
land, or air, and
" (a) to take such remedial action as the Board considers necessary in the public interest, or;
"(b) to report to the Lieutenant-Governor in Council, who may thereafter direct the Board
to take whatever remedial action it considers necessary in the public interest."
The Act further states that the Board has the following powers and duties:—
"(a) To determine what qualities and properties of water shall constitute a polluted
"(b) To prescribe standards regarding the quality and character of the effluent which may
be discharged into any waters:
"(c) To appoint such advisory or technical committees from time to time as may be
deemed necessary to inform the Board with regard to whatever matters may be
referred by the Board."
The Act also prescribes that the Pollution Control Board shall act as an appeal tribunal to
hear appeals taken against any order of the Director of Pollution Control, and in the capacity of
an appeal tribunal the Board " may, on any appeal, determine the matters involved and make any
order that to the appeal tribunal appears just."
The Pollution Control Branch, which deals with matters pertaining to land and water pollution, was formed within the Water Resources Service in 19671 to carry out the administration laid
down in the Pollution Control Act, 1967. The functions of the Pollution Control Branch are to
deal with all matters as prescribed by the Act pertaining to the discharge of domestic or industrial wastes into any of the water resources of the Province. The administration of the Act is
carried forward under the Director of Pollution Control, whose powers and duties are prescribed
in the Act, and are, in summary, as follows:—
(a) To determine what qualities and properties of water shall constitute  a polluted
(b) To prescribe standards regarding the quality and character of the effluent which may
be discharged:
(c) To conduct tests and surveys to determine the extent of pollution:
(d) To examine into all existing or proposed means for the disposal of sewage or other
waste materials:
(e) To notify all persons who discharge effluent into the said waters when the effluent fails
to meet the prescribed standards:
(/) To order any person to increase the degree of treatment of the effluent.
To carry into effect the intent of the Pollution Control Act, 1967, the Director issues permits
to discharge effluent and wastes to applicants who comply with the regulations and who satisfy
the Director that the wastes to be discharged will not cause pollution in accordance with the Act.

The highlight of 1967 was the promulgation of new pollution-control legislation
in the form of the Pollution Control Act, 1967, which replaced the Pollution-control
Act, 1956. The new legislation relieved the Pollution Control Board of the routine
administrative functions associated with issuing permits, a function which was transferred to the Director of Pollution Control. Under this new legislation, the Board
acts in an advisory capacity to the Government, prescribes means of and sets standards for controlling pollution, and acts as an appeal tribunal in matters of appeals
against orders of the Director of Pollution Control.
A brief review of the territorial and operational growth of the Pollution Control
Board is worth noting. Under the original pollution-control legislation of 1956, the
general extent of the jurisdiction of the legislation was the Lower Fraser Valley. In
1961 the territorial area was expanded to include all of the Columbia River drainage
basin which lies within the Province of British Columbia. Again, effective January
1, 1963, the jurisdiction of the pollution-control legislation was enlarged to include
the entire Fraser River basin and most of the populated area of the east coast of
Vancouver Island. On June 20, 1966, the area comprising Strathcona Park on
Vancouver Island was placed under the jurisdiction of the Pollution-control Act.
The Pollution Control Act, 1967, encompasses the entire Province, indicating the
rapid expansion of pollution control since its inception in 1956. Also, since the
inception of the Pollution-control Acts, the Board now has to be cognizant under the
new legislation of land and air pollution.
During the latter part of the year, the Pollution Control Board took two major
steps in fulfilment of its legislated purposes. By Order in Council No. 2836, dated
September, 1967, the Board is directed to inquire into and determine causes of and
remedies for air pollution caused by the emission of particulate matter or the emission of smoke or gases which are determined to be offensive or destructive in character. Furthermore, the Order requires that a full report be prepared on air pollution
and presented to the Lieutenant-Governor in Council before October, 1970. The
requisite studies and evaluations were commenced before the end of 1967.
Secondly, the Board, in its new role, may hold hearings in the public interest.
The first such public hearing was conducted by the Pollution Control Board in
August, 1967, in Whalley, Surrey, B.C. This hearing pertained to the matter of
a report prepared by the Pollution Control Branch bearing the title " Pollution and
the Fraser—Report 1, 1967, Preliminary Investigations of Waste Disposal to the
Lower Fraser River." The purpose of the public hearing was to receive testimony
relative to the findings of the report which would assist in establishing policy for
the control of water pollution in the Lower Fraser River basin. Following the hearing the Pollution Control Board accepted in principle the basic recommendations of
the report, which may be summed up briefly by saying that, as a general rule, all
sewage discharges to the Lower Fraser River should receive primary treatment and
chlorination, with more restrictive requirements in certain specific areas.
C. J. Keenan, P.Eng.
Director of Pollution Control
Following the transfer of the administration of the operative functions of pollution control to the Water Resources Service in 1965, this Service was able in 1967
to lay the foundation for a Pollution Control Branch. Under the Director of Pollution Control, there are now established 16 positions, eight of them engineering posts,
the remainder comprising technician, draughting, and stenographic positions. A
significant step taken in 1967 was the establishment of field staff. With the increasing needs in the Okanagan, a District Engineer and an engineering technician have
been allocated to that area. A second field office has been organized to give service
in the Kootenays. Here again it has been possible to assign a District Engineer and
an engineering technician to the area. A laboratory technician position was created
to assist in the analysing of water samples, which is carried out in the Public Health
The administrative functions associated with investigating and processing applications for permits are carried forward by the Pollution Control Branch. The facts,
general, administrative, and technological, of each investigation are laid before the
Director. The Director may grant, may amend and grant, or may refuse to grant
a permit. Applicants must satisfy the Director that the waste to be discharged will
not cause pollution in accordance with the Act. All valid objections to the issuance
of a permit are investigated, and, in some cases, public hearings or inquiries are held
before a final decision is taken on the application. During the current year one
public hearing and one inquiry were held by the Director to facilitate the proper
determination of certain factors. During 1967, 83 permit applications were received,
with 40 permits being granted. The remaining 43 applications were either rejected
as likely to cause pollution or are being held in abeyance awaiting resolution of
extenuating circumstances.
The Pollution Control Branch completed a report dealing with the Lower
Fraser River under the title of "Pollution and the Fraser—Report 1, 1967, Preliminary Investigations of Waste Disposal to the Lower Fraser River." Following
a review of the proposals and a public hearing on the matter, the Pollution Control
Board accepted the general recommendations set out in the report.
In 1967 considerable interest in pollution was generated in the Okanagan
primarily as a result of algae in the lake waters. In order to explore the problem,
an algae study was undertaken by the University of British Columbia under the
auspices of the Water Resources Service. A continuous water-quality sampling
programme was also set up in conjunction with the International Hydrologic Decade
programme of the Department of Energy, Mines and Resources, Canada, using five
sampling-stations within the Okanagan and Skaha Lakes system. Furthermore,
pollution-control staff have been recruited and, following a brief orientation pro-
gramme, personnel will be placed in the Okanagan early in 1968. One of the functions of this new group will be to undertake an intensive three-year study of the
pollution factors in the Okanagan and to prepare a comprehensive report evaluating
the situation with recommendations. A similar report is programmed for the
Columbia-Kootenay basin.
An important area of continuing interest in 1967 was pulp-mill effluent discharge, particularly at those mills currently under permit and discharging to inland
waters. Each mill is required to undertake an approved monitoring programme
under the surveillance of the PoUution Control Branch. The findings of each set
of results are plotted to evaluate on a continuous basis the effectiveness of the waste-
treatment facilities. The standards set for the mills under permit are amongst the
highest requirements to be found anywhere. It may be reported also that with an
upsurge in mining interests, many discussions were carried forward with new mining
ventures, at which time the requirements to prevent possible pollution were explored,
such requirements making it necessary for the mines, in some cases, to revolutionize
their proposed means of effluent tailings discharge.
Last year Strathcona Park was placed under the jurisdiction of the Pollution
Control Act to ensure a close surveiUance of the mining operation in the park, which
discharges tailings to Buttle Lake. The permit issued for the mining operation
called for a high-quality effluent and rigorous maintenance. A comprehensive continuing sampling programme was started in 1967 by the Pollution Control Branch.
It is reassuring to reflect the advances made in 1967 in the field of pollution
control in the Province of British Columbia. New and more effective legislation
was enacted to cover the entire Province. The budget to operate the PoUution Control Branch was increased, which allowed a corresponding increase in staff. Public
hearings and inquiries to ascertain public interest were conducted. Pollution-control
studies, monitoring and surveillance programmes were carried out and new ones
initiated. Major industries have demonstrated in many areas their willingness to
accept responsibility in the control of pollution arising from their operations. In
summary, all of the foregoing bodes well for the preservation and development of
the Province's natural resources.
