Thomson Reservoir,[1] also known as Thomson Valley Reservoir,[2] is an irrigation reservoir on the upper East Fork of Silver Creek in the Fremont National Forest, approximately ten miles upstream from Silver Lake, Oregon, in the United States. Constructed in 1930 alongside a dam by the Silver Lake Irrigation District, Thomson Reservoir spans roughly 1800 acres and can hold 7750 acre-feet of water.
Biology
Thompson Reservoir is classified as mesotrophic. There are low densities of A. formosa in the spring and low densities of C. hirundinella and M. granulata in summer. Due to the extreme water fluctuations from reservoir operations, macrophytes are scarce.[3]
Recreation
Thomson Reservoir is accessible by road. It contains two United States Forest Service campgrounds. The reservoir itself is located within the National Forest, but half of the shoreline is held by private owners. The dominant fish species is the tui chub and its high population has resulted in a decline of rainbow trout. As a result, each spring the reservoir is stocked with about 200,000 fingerling trout. Due to the overpopulation of "rough fish", the camping facilities are not heavily used.[2]
