Data sets for the Upper Penticton Creek Watershed Experiment : a paired-catchment study to support investigations of watershed response to forest dynamics and climatic variability in an inland snow-dominated region Moore, R. Daniel; Allen, D. M.; MacKenzie, Lucy; Spittlehouse, David L.; Winkler, R. D.


The Upper Penticton Creek Watershed Experiment is one of a handful of forestry-focused pairedcatchment experiments in the snow-dominated zone of western North America. The study involves an undisturbed control catchment and two treatment catchments. Streamflow has been monitored at weirs on all three streams since 1985. Following a pre-harvest monitoring period, the treatment catchments were subject to clearcut harvesting in multiple passes that cumulatively covered ~50% of the catchments. In addition to streamflow, available hydrometeorological data sets include weather observations, snowpack water equivalent, rainfall interception, soil water content, and water table levels in soil piezometers and bedrock wells. The data archive also includes digital elevation models, a Lidar-derived image of tree heights in 2016, and vector data associated with lakes and reservoirs, the stream network, clearcut boundaries, a soil map and the logging road network. Together, these data sets provide a basis for empirical analyses of hydrological response to forest dynamics and climatic variability, and for calibration and testing hydrological models using internal variables. They should also provide useful data sets for educational purposes.
