Starting in the 1920s, individuals and irrigation companies constructed and created reservoirs in the Uinta Mountains. Today, these high mountain lakes store and supply approximately 22,000 acre-feet of water to non-Indian land in the Duchesne River Basin. In the 1960s, Big Sand Wash Reservoir was built. This reservoir has a capacity of 12,100 acre-feet of supplemental irrigation water for non-Indian lands. In 1982 construction of Brown's Draw Reservoir, an off-stream storage facility, was completed by the Moon Lake Water Users. Brown's Draw provides 6,600 acre feet of storage for supplemental irrigation of non-Indian lands on the Uinta River. Numerous other small reservoirs have been constructed throughout the Duchesne River Basin totaling approximately 25,000 acre feet of supplemental storage for non-Indian lands. In summary, approximately 122,000 acre-feet of storage and exchanges have been developed by non-Indian farmers on the Uinta and Lake Fork River systems. FEDERAL WATER DEVELOPMENT Federal non-Indian water development in the Green River Basin (and principally the Duchesne River Basin) began at the turn of the century and increased dramatically under CRSP. While some of this development was for the benefit of non-Indian farmers in the Basin, the vast majority was designed to divert water from the Basin over the Wasatch Mountains to Utah and Salt Lake Counties on Utah's western slope. 29 Flaming Gorge Dam, Reservoir, and Powerplant, which make up the Flaming Gorge Unit of the Colorado River Storage Project, were authorized for construction under CRSP and began operations in 1963. The dam is a 502-foot tall concrete structure and the reservoir capacity is 3.79 million acre-feet. The reservoir area is about 42,000 acres and the powerplant capacity is 152 megawatts. The Strawberry Valley Project provided the first large-scale transmountain diversion from the Colorado River Basin into the Bonneville Basin. Early investigations began in 1903 and the project was authorized in 1905. Construction began in 1906 and the completed project was fully operational by 1922. Water is stored in Strawberry Reservoir on the Strawberry River, a tributary of the Duchesne River. The reservoir also receives water through direct diversions from Indian Creek, Trail Hollow Creek, and Currant Creek, all tributaries of the Strawberry River and hence the Duchesne River. The stored water was historically diverted into the Bonneville Basin through the Strawberry Tunnel under the Wasatch Divide. The water was discharged into Diamond Fork, a tributary ofthe Spanish Fork River, from which it was delivered for irrigation of about 44,500 acres of land and power production purposes. With the authorization and construction of the Bonneville Unit of the CUP, discussed below, the capacity of this transmountain diversion project was dramatically increased.
