Upper Basin 34 Reservoirs FonteneIle Flaming Gorge Coreeanti linit The reservoir water level will be lowered through the fall and \winter months until a water sur- face elevation of about 6,480 feet is reached. With average runoff during the spring months., Fon- tenelle Reservoir will fill by the end of June. After the spring run. off, the reservoir level will be controlled by adjusting the re- leases th rough the powerpJant to slowly reduce the elevation to 6,502 feet by the end of the summer of 1976, (Chart 1.) At the beginning of water year 1976, the active storage in Flam- ing Gorge Reservoir was 3,650,000 acre. feet, with a water surface at elevation 6,037 feet. The reservoir level will be lowered about 10 feet by March of the current year, but should remain high enough until the spring runoff so boats can be launched from all of the nine boat ramps. Average inflow would cause the reservoir to reach eleva- tion 6,035 feet with an active star. age of 3,530,000 acre.feet. Sum. mertime flow in the river below the dam should not exceed 4,500 ft3 / s and would not be less than 800 ft3 / s. Releases should average about 150,000 acre-feet per month through September 1976 for a water year total of about 1,900,000 acre. feet. (Chart 2,) During the current year, the water level in Blue Mesa Resen-oir should reach a low in March 1976 at elevation 7,4.64 feet and the active storage would be 400,000 acre. feet. With average inflow dur- ing the spring of 1976, the reser. voir should fill at elevation 7,519 feet with an active storage of 830,000 acre.feet. At that elevation the reservoir has a surface area of 9,180 acres and a reservoir length of 24 miles. (Chsrts 3 snd 4.) Morrow Point Reservoir will be operated near full during the CUT- rent year. Releases of a minimum flow.of 200 ft'/s will be made below the Gunnison Tunnel Diversion Dam for downstream irrigation requirements, power production, and river regulation.
