SUMMARY The Bonneville Unit of the Central Utah Project will be located in central and northeastern Utah. Project water will be developed by col- lecting and storing excess flows of several streams, principally tribu- taries of the Duchesne River, by purchasing water rights and using a portion of the existing water supply in Utah Lake, and by using project return flows and high flows entering the lake. The unit will include features to facilitate a transbasin diversion of water from the Uinta Basin to the Bonneville Basin and related developments of local water resources in both basins. The project water supply will be used for municipal and industrial purposes and irrigation in both basins and to generate power for project pumping purposes in the Bonneville :Basin. The project will also provide flood control, recreation, and fish and wildlife measures. For convenience in planning and coordination, the :Bonneville Unit is divided into six systems according to location and function. These systems are (1) the Starvation Collection System, (2) the Strawberry Collection System, (3) the Ute Indian Tribal Development (formerly the Bureau of Indian Affairs Activity), (4) the MuniCipal and Industrial System, (5) the Diamond Fork Power System, and (6) the Irri- gation and Drainage System. The functions of each of the systems are discussed below. Starvation Collection System The Starvation Collection System was essentially completed in 1970. The system develops water for irrigation and municipal uses and provides flood control, recreation, and fish and wildlife measures in the Duchesne area of the Uinta Basin. Regulatory storage 'is provided by Starvation Reservoir, located on the Strawberry River just above its confluence with the Duchesne River. The reservoir provides a large supply of water to replace Duchesne River flows presently used for irrigation which will be diverted to the Bonneville :Basin. The reservoir also develops a smaller supply of water for irrigation of lands along the Duchesne River and a small amount. for local municipal use. The reservoir is filled by surplus winter and spring flows of the two rivers. Duchesne River water is diverted by Knight Diversion Dam and conveyed to the reservoir through the Starvation Feeder Conduit. The reservoir also provides wildlife mitigation measures and recreation facilities. Strawberry Collection System The nearly completed Strawberry Collection System will intercept flows of Rock Creek and eight other tributaries of the Duchesne River and convey them to the existing Strawberry Reservoir for storage. The reservoir was enlarged by construction of Soldier Creek Dam on the Straw- berry River below the reservoir. Some of the project water stored in the reservoir will be used in the Uinta :Basin, but most will be exported for use in the :Bonneville :Basin. Upper Stillwater Reservoir, which is S-1 I I
