<br />Flam i ng Gorge <br /> <br />At the beginning of water year] 975 the active reservoir <br />storage was 3,580,000 acre-feet with a water surface at <br />elevation 6,036 feet. The reservoir level will be lowered about <br />7 feet by March of the current year but should remain high <br />enough until the spring runoff so that boats can be launched <br />from all of the nine boat ramps. During the latter part of <br />March and through April 1975, releases from the reservoir <br />will be managed to encourage the geesc to nest back away <br />from the river in Brown's Park. This will be accomplished <br />by varying the releases every other day from high to low <br />flows until nests are established. Flow will then vary on a <br />more unifor'm pattern throughout the summer, but the river <br />should not exceed 4,500 ft3/s and normally would not be <br />less than 800 ft3/s. Releases should average about 150,000 <br />acre-feet per month through the. rest of the summer for a <br />water year total of 1,550,000 acre-feet. (Chart 2) <br /> <br />Curecanti Unit <br /> <br />During the current year, Blue Mesa should reach a low <br />for the year in April 1975 of elevation 6,453 feet with an <br />active storage of 330,000 acre-feet. With average in flow <br />during the spring of 1975, the reservoir should reach <br />elevation 7,518 feet with an active storage of 820,000 <br />acre-feet. At this elevation the reservoir has a surface area <br />of 9,102 acres and a reservoir length of 24 miles. (Charts 3 <br />and 4) <br /> <br />Morrow Point Reservoir will be operated near full <br />during the current year. Releases will be made for <br />downstream irrigation requirements plus a flow of 200 ft3/s <br />below the Gunnison Tunnel Diversion Dam. <br /> <br />Navajo- Reservoir <br /> <br />On September 30. 1974, Navajo Reservoir had an active <br />storage of 1,019,000 acre.-feet with. an elevation of 6,030 <br />feet. During October through March releases will be <br />controlled to lower the reservoir elevation to 6,028 feet prior <br />to spring runoff. Average inflow would cause the reservoir <br />to reach elevation 6,060 feet with an active storage of <br />1,350,000 acre-feet. It will be maintained for recreational <br />purposes at or near this level for the remainder of the <br />summer. (Chart 5) <br /> <br />30 <br />
