Reservoirs in the drainage cover 814 surface acres, and are used for irrigation water storage. Two reservoirs, Daniels and Devils Creek, have minimum pools for fish. These reservoirs are stocked annually with rainbow trout. Populations of spiny-rayed fishes occur in all but Deep Creek and St. John's Reservoir. Collectively, these reservoirs provide significant fishing opportunity. Little is known, however, about harvest or fishing pressure.
Daniels Reservoir was historically managed as a trophy trout fishery with a two-fish limit. Following treatment for Utah suckers in 1988, Daniels was stocked with rainbow-cutthroat hybrids and Lahontan cutthroat.Stone Reservoir is located on Deep Creek in Curlew Valley approximately 6 miles north of Snowville, Utah. It is managed from the Magic Valley Region. It is stocked with rainbow trout annually and has self sustaining populations of largemouth bass and crappie. However during the 1987-1992 drought, the warmwater fish populations were greatly reduced.
