Data and Report from S&T Project 19080: Aging Reservoirs, Climate, Operations, and Potential Cumulative Impacts to Water Quality, Clarity and Fisheries and Recreation

Report on Clark Canyon water quality with respect to turbidity, modelling efforts and ADP analysis of in reservoir currents. Clark Canyon Reservoir has been releasing waters with elevated levels of turbidity into the downstream Beaverhead River. This study was initiated in cooperation with the State of Montana to study why these turbidity episodes occur. Daily reservoir profile data attached as separate files for this project, in addition to data owned by the State of Montana, were used to help describe in reservoir conditions, and were used in concert with ADCP data (supplemental report and appendix) and the development of a CE-QUAL model to help describe reservoir processes leading up to downstream turbidity events. Results indicate episodes are likely seasonal events and not the result of a sediment layer that has built up over time. Turbidity episodes most commonly occur under lower reservoir conditions when stratification is not strong and when wind events out of the North occur.
