The Upper Penticton Creek (UPC) watershed experiment is a paired-watershed study into the effects of forest harvesting on water resources and is comprised of three, 5 km2, high elevation watersheds typical of the Okanagan Plateau. The goals of this long-term experiment are to improve our understanding of hydrologic processes and to develop effective forest practices guidelines that sustain both the timber and water resources of the BC interior plateau. Data collected over the past 20 years enables researchers to study the effects of road construction and logging on diverse watershed features and processes including streamflow, snow accumulation and melt, water use by vegetation, stream channels, aquatic invertebrates, and water quality.
