<br />Flaming Gorge Reservoir <br />[Green River] <br /> <br />Wotor Yoor 1983 <br /> <br />At the beginning of water year 1983, Flaming <br />Gorge Reservoir .lorad 3,572,000 acre-feet al <br />water .urlace elevallon 6036 feet. Dueto high <br />carryover storage and 8cheduled spillway <br />repair work, higher than normal releases <br />through the reservoir were scheduled tor <br />water year 1983. <br /> <br />The water surface was drawn down to <br />alavatlon 6025 feet prior to tha .prlng runoff. <br />During the draw down, average dally outflow <br />from the re.ervolr rarely fell below 2,500 cf.. <br />However, due to rBcord runoff abovB Flaming <br />Gorge, the re.ervolr filled to elevallon 6040 <br />feet by mldaJune, and contInued to rlS9 almost <br />.n additional 4 feet Into .urcharge. A.the <br />Nater surface elevation approached 6040 feet, <br />. decl.lon was made to place 5-foot high <br />"elnforcad wooden extensions on the splllwsy <br />la'e.,o 11m II the flow through tha .plllway, <br />thereby minimizing damage 10 Ihe yet <br />unflnl.hed .plllway repair work. 'Maximum <br />water surface elevation reached 6044 feet with <br />astorage of 3,g1 1,100 acre-feet. By Ihe end of <br />the water year, the reservoir w8slowered to <br />elevallon 6038 feat and .tored 3,676,000 <br />!lere-feet of water. <br /> <br />~unoff above Flaming Gorge Reservoir for the <br />Nater year was 3,115,000 acre-feet, or 200 <br />lsrcent of the average. MaxImum Inflow Into <br />'laming Gorge ot 18,350 cf. occurrad on June <br />1,1983. During the period of peak Inflow, <br />naxlmum average dally releases from the <br />e.ervolr ranged from 8,000 10 10,000 cf.. <br />lowevor, another peak Inflow of 15,120 cf. <br />ccurred on July 5, 1983, which coincided with <br />16 directed rapid drawdown of Fontenelle <br />:e.ervolr up.tream. During thl. period a <br />18xlmum release of 12,000 was sustained for <br />days, and was then gradually reduced to <br />.000 cfs over the next few weeks. The <br />!servolr outflow then remained at or near <br />000 ct., powerplant capacity, throughoullhe <br />Imalnder of the water year. <br /> <br /> <br />:~. <br />TUnnel IPlllw.y In operatlon.t FlamIng Gorge OlIm. <br /> <br />Wstor Yoar1984 <br />During water year 1984, the reservoir water <br />surface level at Flaming Gorge Reservoir Is <br />projected to be drawn down from elevation <br />6038 'eet 10 aboul elevation 6023 feet before <br />Ihe .prlng 011984. ihowalor aurlscelevel <br />will remain high enough under any Inflow <br />conditions to launch boat' from the rsservolr's <br />nine ramps.
