<br />Flaming Gorge Reservoir <br />(Green River) <br /> <br /> <br />Setting sun reflects 011 Flaming Gorge Lake. <br /> <br />WatarYaar1981 <br />At the beginning of water year 1981, the <br />reservoir water surface elevation was 6,023 <br />feet with a content of 3,076,800 acre-feet. <br />Prior 10 the spring runoff the reservoir <br />elevation was drawn down to 6,019 feet. The <br />Aprillhrough July 1981 runoff above Flaming <br />Gorge was 576,000 acre-feet, 50 percent of <br />the long-term average, With this runoff, the <br />reservoir reached its seasonal maximum <br />elevation of 6.021 feet with a content of <br />3,027,000 acre-feet by mld-July, By the end of <br />September. the elevation was 6.018 feet with <br />a content of 2.916.800 acre-feet. <br /> <br />The normal minimum release at Flaming <br />Gorge Reservoir is 800 IP/s. The maximum <br />release through the powerplant Is 4.600 ft'ls <br />3t rated head, During the water year, a total of <br />1,063,000 acre-feet was released through the <br />powerplant. <br /> <br />~:'i_ >.

Average inflow would <br />result in a maximum elevation of 6,027 feet <br />with a storage of 3,247.000 acre-feet during <br />July, <br /> <br />Since there are both enough storage space <br />for a high inflow and enough stored water in <br />case of a low inflow, releases from Flaming <br />Gorge are not dependent on inflow for water <br />year 1982. but rather on the demand for <br />electric power and the availability of energy <br />for purchase and exchange. <br /> <br /> <br />Three selective withdrawal structures. <br /> <br />Resef\loir <br /> <br />Flaming Gorge Active Storage" Chart 2 <br /> <br />(Acre-Feet) <br /> <br />Maximum Storage <br />Rated Head <br />Minimum Power <br />Surface Area (Full) <br />Reservoir Length <br />(Full) <br />Power Plant <br /> <br />Number of Units <br />Total Capacity <br /> <br />EI. <br />(Ft.) <br /> <br />3,749,000 6040 <br />1,062,000 5946 <br />233,000 5871 <br />42,020 Acres <br /> <br />91 Miles <br /> <br />"does nol include 40,000 .cre.!eel 01 dead storage <br />below 5740 teel <br /> <br />3 <br />108,000 Kilowatts <br />
