6 Paonia Project This west-central Colorado Project consists of the Fire Mountain Canal and Paoui.a Dam and Reservoir. Paonia Reservoir has a total storage capaci.ty of ,21,000 acre-feet nth an estimated 9,800 acre-foot annual depletion from the Gunnison River. Fruitgrawers Project The Fruitgrowers Dam project in southwestern Colorado furni.shes irrigation water for nearly 2,700 acres. The reservoir behind Fruitgrowers Dam, filled from natural flow of Alfalfa Run and by diversion from Surface and Dry Creeks, stores a total of 4,600 acre-feet of water with an ,estimated annual depletion of 7,200 acre-feet from the Gunnison River. Construction of the dam was completed in 1939. . Uncompahgre 'Valley Project This. project is on the western slope of the Rocky Mountains in west- central Colorado. Project features include the Taylor Park Dam and Reservoir, Gunnison TUnnel, seven diversion dams, 143 miles of main c"n,,'s, 425 miles of laterals, and 215 1Ili.les of drains. The system diverts water from the Uncompahgre and Gunnison Rivers to irrigate over 76,000 acres of land. Taylor Park Dam, on the Taylor River, creates a reservoir with a storage capacity of 106,200 acre-feet, with an estimated annual depletion of 5.200 acre-feet from the Gunnison River. All of the projects were completed by r9~7. Dominguez Project The Dominguez Reservoir project would be located along the Gunnison River near Whitewater, Colorado. This multi-purpose project would develop water for hydroelectric power and industrial consumption. Dominguez Reservoir would inundate 26 miles, of river and have a storage capacity of 302.000 acre-feet of water with an annual depletion of 68,000 acre-feet from the Gunnison River. Congress will probably consider construction authorization somet~e in 1981. Cumulative Effects The above projects deplete a total of 158,000 acre-feet of water annually. Based on la-year flow records (1968-1978) recorded by the U.S. Geological Survey and published in the Water .Resources Data Annual Reports for Utah and Colorado, the average annual depletions from the above CRSP reservoirs on the Gunnison River is 8 percent of the annual flows. The cumulative depletion of flow considering maximum depletion for each project in a high-water-year (1970) would be 7 percent and for a low water year (1977) 13 percent of the annual flow. We consider these figures to be conservative estimates because they do not include all of the diversions nor any evaporation 10ss~s.
