Inflows have decreased to below 1200 cfs while the total reservoir <br />releases are currently set at 1200 cfs, Releases will remain at the current level throughout the fall and <br />winter months. The water surface elevation will steadily decline until April of 2000. <br /> <br />FLAMING GORGE - Average daily releases from Flaming Gorge Reservoir are now 2100 cfs. <br />Releases will likely remain at or near 2100 cfs through the fall months. <br /> <br />Some hour to hour fluctuations in releases are now occurring. The amount of fluctuation is being <br />constrained by the 1992 Flaming Gorge Biological Opinion (FGBO) which states that flows on the <br />Green River near Jensen, Utah shall change by no more than plus or minus 12.5 percent of the daily <br />average flow for the day. Genenilly, the range (high to low) of fluctuations at Flaming Gorge has <br />been about 1000 cfs on any given day. <br /> <br />Inflow to Flaming Gorge was much above average during the 1999 runoff season. April through <br />July unregulated inflow was 1,706,000 acre-feet (143 percent of average). The last time April <br />through July inflow was this high was 1986, August unregulated inflow was 118,000 acre-feet, 110 <br />percent of average, Unregulated inflow in September was 84,600 acre-feet (127 percent of average), <br /> <br />Open forum discussions on Flaming Gorge operations have been taking place at meetings of the <br />."Flaming Gorge Working Group", The next Working Group meeting is scheduled for January 13 at <br />II am in Heber, UT.
