<br />13fd <br /> <br />. <br /> <br />B. <br /> <br />Ruah Reservoir <br /> <br />Ruedi Reservoir will be operated in water year 1982 to best control <br />spring runoff, recreational interests, and requirements for downstream <br />fishery. This is an interim plan until a long tenn market is developed <br />for that water. Short tenn sales may be made on a year-to-year basis as <br />the need develops. <br /> <br />1. Inflow <br /> <br />Under rrost probable ronditions, the annual inflow will be 102,600 acre- <br />feet. <br /> <br />2. Minimum Release <br /> <br />The fish~ bypass requirements, as described in the ClJerating Principles, <br />are 39 ft /s fran November through April and 110 ft3/s from May through <br />O::tober or inflow, whichever is less. <br /> <br />3. Reservoir ~ations <br /> <br />. <br /> <br />The planned release f= Ruedi Reservoir for October through April is <br />approximately 150 ft3/s which v.ould draw the reservoir Cbwn to an eleva- <br />tion of 7706.0 feet by April 30, 1982. lbwever, based upon the type of <br />runoff season indicated by nonthly snowpack data, the outflow fran the <br />reservoir and the target elevation will be adjusted. To provide maximum <br />flood protection below the dam, the reservoir will be drawn down by <br />March 31, 19B2, to where refilling v.oul.d be assured during the spring <br />runoff. Estimates of prObable inflow will be made following the February <br />1, March 1, April 1, and May 1 SOCM forecasts; the draw:'lown will be <br />adjusted accordingly. <br /> <br />West Slope recreation interests requested that the reservoir water level <br />not be drawn down below elevation 7706.0 feet (53,000 acre-feet), which <br />is 2.0 feet above the !:ottan of the Forest Service !:oat rarrp. This <br />request will be hooored until long tenn rontracts are developed for sale <br />of storage water. The operating plan used will assure the reservoir <br />will be filled by the first of July, thus providing the best recreational <br />benefits during the SlI111l1Er nonths. <br /> <br />After July 1, the operating plans call for maintaining the reservoir at <br />elevation 7764.0 feet (2.0 feet below the spillway crest) until August <br />1. Then, only inflow and srott tenn rontracted deliveries will be <br />passed during the nonth of August. The Colorado Division of Wildlife <br />has requested that the outflow be maintained at 100 ft3/s during September <br />to make the best of downstream fishery. These flows will be maintained <br />under normal ronditions. If ronditions warrant, the outflow during <br />these nonths may be adjusted to ronserve water. <br /> <br />. <br /> <br />If water is sold to entities downstream, the outflow fran the reservoir <br />will be adjusted to the situation at the time of delivery and will be <br />included in the overall operation. <br /> <br />17 <br />
