<br />...... II'" <br />1~1~1 <br /> <br />. <br /> <br />of July. After July 5, the operating plan is to maintain the reservoir as <br />near as possible to elevation 7764.0 feet (2.0 feet below the spillway <br />crest) until it is necessary to draw the reservoir down for downstream <br />demands or for storage of the spring runoff. The Colorado Division of <br />Wildlife has requested that the outflow be maintained at 100 ft3/s from <br />September 1 through November 15 to enhance the downstream brown trout <br />spawning. These flows can be maintained under normal conditions. <br /> <br />If water is sold to entities downstream, the outflow from the reservoir will <br />be adjusted to the situation at the time of delivery and will be included in <br />the overall operation. <br /> <br />. <br /> <br />Table 10 and exhibit 18 show the anticipated operation of Ruedi Reservoir <br />during water year 1984. <br /> <br />C. West Slope Collection System <br /> <br />In water year 1984, all 16 diversions in the West Slope collection <br />system will be in operation. The exchange of up to 3,000 acre-feet of water <br />into the Roaring Fork River with the Twin Lakes Reservoir and Canal Company <br />sys tem will be made agai n th is year. Under the terms of the exchange the <br />water is to be furnished to the Canal Company at Twin Lakes. This exchange <br />wi 11 be done through and by means of project diversions and storage in <br />exchange for the Canal Company making equivalent releases from the head- <br />waters of the Roaring Fork River. The Canal Company's releases would other- <br />wise be diverted through their collection and diversion system. The <br />exchange wi 11 be operated accord i ng to the agreement with the Twi n Lakes <br />Reservoir and Canal Company (appendix B). <br /> <br />D. Turquoise Lake <br /> <br />1. I nf 1 ow <br /> <br />Inflow to Turquoise Lake for water year 1984 will be from four <br />sources: Busk-Ivanhoe imports, project imports, Homestake Project imports, <br />and native flow of Lake Fork Creek. Estimates of inflow from Busk-Ivanhoe <br />and native Lake Fork Creek were made using historical records and probabi- <br />lity analysis. Homestake project plans to import about 4,500 acre-feet of <br />water now stored in Homestake Reservoir. Project water imports are esti- <br />mated to be 69,200 acre-feet. <br /> <br />2, Minimum Release <br /> <br />The minimum release into Lake Fork Creek is 15 ft3/s, or <br />natural inflow, whichever is less. <br /> <br />. <br /> <br />21 <br />
