Short-term sales may be made on a year-to-year basis as the need develops for water. The planned releases from Ruedi Reservoir are for about 160 cubic feet per second until late November, then increase to 200 cubic feet per second until the end of April which would draw the reservoir down to an elevation of 7706 feet. However, based upon the type of runoff season indicated by monthly snowpack data, the outflow from the reservoir and the target elevation may be adjusted. Monthly estimates of probable inflow would be made following the February 1 through May 1 runoff forecasts. . The minimum release requirements, as described in the operating prin- ciples, are 39 cubic feet per second from November 1 through April 30 and 110 cubic feet per second from May 1 through October 31 or n at ive inflow, whichever is less. These flows include water from Rocky Fork. Recreation interests requested that the reservoir water level not be drawn down below elevation 7706 feet (53,100 acre-feet), which is 2 feet above the bottom of the Forest Service boat ramp. The Operating Plan indicates that the reservoir.will be filled by about July 3, thus providing recreational benefits during the surraner months. Flows on the Fryingpan River below Ruedi Dam during May and June should be in the 200 cubic feet per second range. After July 3, the Operating Plan is to maintain the reservoir as near as possible to elevation 7764 feet (2 feet below the spillway crest) until it is necessary to draw the reservoir down for downstream demands or for storage space for next spring runoff. The Colorado Division of Wildlife has requested that the minimum outflow be maintained at or above 100 cubic feet per second from September 1 through November 15 to enhance the downstream brown trout spawning. These flows can be maintained under normal conditions. If water is sold to entities downstream, the outflow from the'reservoir will be adjusted to the situation at the time of delivery and will be included in the overall operation. Table 10 and exhibit 19 show the anticipated operation of Ruedi Reservoir during water year 1987. C. West Slope Collection System In water year 1987, the West Slope Collection System will be in operation to divert approximately 27,500 acre-feet of water from the Fryingpan River Basin and about 3,000 acre-feet from the Hunter System. The exchange of up to 3,000 acre-feet of water into the Roaring Fork River with the Company's system will be made again this year. Under the . 17
