. . . EVALUATIONS OF LXISTI~G SALI~ITY CO~~ITIONS 1. Fontenelle Reservoir Fontenelle Reservoir, located on the Green River above Green River. ~.. Wyoming. has a storage capacity of 345.000 acre-feet (150,000 active) and ~ regulates the flow in the Green River above Flaming Gorge Reservoir. It ~ will be used to supply water to the Seedskadee Project including municipal ~l and industrial uses and for wildlife refuge purposes. 2. Flaming Gorge This storage unit is located on the Green River in northeastern Utah and southwestern Wyoming. The primary purposes of the Flaming Gorge Unit are river regulation, storage of flood flows of the Green River, and the generation of hydroelectric power. The reservoir has a storage capacity of 3.789,000 acre-feet (3.516,000 active). The stored water assists in complying with the terms of the Colorado River Compact and, by exchange. furnishes an irrigation supply for the participating projects in the Upper Basin States. In addition there are benefits from fish and wildlife conservation and recreational facilities. Storage commenced November 1. 1962, and from the records taken immediately below the dam it shows that the reservoir releases are more uniform in quality than uncontrolled streamflow prior to reservoir construction. J. Curecanti Unit Facilities of the Curecanti Unit, located in west-central Colorado, include the Blue Mesa. Morrow Point. and Crystal Dams. Reservoirs, and Powerplants. The primary purposes are regulation and storage of flood flows of the Gunnison River and generation of hydroelectric power. In addition benefits are provided to recreation, fish and wildlife con- servation, and irrigation. The reservoirs of the Curecanti Unit help regulate the flows of the Colorado River at Lees Ferry. The storage capacity provided is 941,000 acre-feet (749,000 active) at Blue Mesa. 117.000 acre-feet (42,000 active) at Morrow Point, and 27.000 acre-feet (13,000 active) at Crystal Reservoir with total reservoir evaporation losses estimated to average 10,000 acre-feet annually for all three reservoirs. Storage was initiated late in 1965 at the Blue Mesa Reservoir and on January 24. 1968, at the Morrow Point Reservoir. Construction is almost completed on Crystal Dam. 4. ~avajo The Navajo Dam and Reservoir are located on the San Juan River in northwestern New Mexico and southwestern Colorado. Total storage capac- ity of the reservoir is 1,709,000 acre-feet (1,036.000 active). This reservoir regulates the flow of the river for irrigation of the Hammond Project, the Navajo Indian Irrigation Project, and for other uses including by exchange potential uses above the reservoir and transmountain diversions 46
