Show World War II priorities until about 1952. Under this project, the 6- mile- long Duchesne Tunnel was constructed to divert water from the North Fork of the Duchesne River to the Provo River. The Weber- Provo Diversion Canal was enlarged to permit increased diversions from the Weber River. These two sources supply most of the water for Deer Creek Reservoir on the Provo River, near Heber, Utah. The reservoir water is used for power production, irrigation, and municipal purposes. About half of the project water is distributed by the Salt Lake Aqueduct for municipal purposes. This project would not be adversely affected by the Bonneville Unit. The Moon Lake Project was constructed in the 1935- 41 period to provide supplemental irrigation water to 75,256 acres of land located north of the Duchesne River. Some Lake Fork water formerly used on Indian lands below the Moon Lake Project is now used for this project. Replacement water for the Indian lands involved is diverted from the Duchesne River about 6 miles below Duchesne and conveyed to the Indian lands by the Duchesne Feeder Canal. Part of the water stored in Starvation Reservoir is available to assure fulfillment of this exchange agreement with the Indians in the Midview area and thus stabilize the Moon Lake Project. Private Development Base flows of the Wasatch Mountain streams that enter the Bonneville Basin were appropriated and used for irrigation and other purposes within a few decades after settlement of the area began in 1847. Diversion structures, canals, and some storage reservoirs have been constructed. Utah Lake was developed as a storage reservoir in 1872. A pumping plant was built in 1902 to permit lowering the lake below the outlet elevation. Most of the water released from Utah Lake is re- diverted from the Jordan River for irrigation in the Salt Lake Valley and northern Utah Valley. Some of the water is used for municipal and industrial purposes, either directly or by exchange with frontal streams. Evaporation from Utah Lake averages about 325,000 acre- feet annually, which is more than half of the estimated inflow to the lake. The proposed Bonneville Unit would reduce the evaporation loss by about a third. Jordan- Provo River Parkway The Jordan- Provo River Parkway Authority which was recently enacted into law by the Utah State Legislature could affect future development in this area, including some Bonneville Unit features.
