1821 . Flows on the Fryingpan River below Ruedi Dam during May and June should be in the 200 to 500 cubic feet per second ra~ge. After June 30, the Operating Plan is to maintain the reservoir as inear as possible to ele- vation 7764 feet (2 feet below the spillway cre$t) 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 con- ditions. ' If water is sold to entities downstream, the 0~tf10w from the reservoir wi 11 be adjusted to the s ituat i on at the time' of deli ver y and wi 11 be included in the overall operation. Table 13 and exhibit 21 show the anticipated operation of Ruedi Keservoir during water year 1988. C. West Slope Collection System In water year 1988, the West Slope Coll'ection System will be in operation to divert approximately 3,000 acre-feet of water from the Hunter System. No diversions from the Fryingpan River Basin are antici- pated during this water year. The present plan is to curtail project imports to allow for the drawdown at Twin Lakes in preparation of the removal of the two dikes and construction of a,bypass channel around the old outlet works. The work is tentatively sc~edu1ed for October, 1989. The exchange of up to 3,000 acre-feet of waller into the Roaring Fork River with the Company's system will be made again this year. Under the terms of the exchange the water is to be futnished to the Company at Twin Lakes. This exchange will be done through and by means of Project diversions and storage in exchange for the Company making equivalent releases from the headwaters of the Roaring Fork River. The Company's releases would otherwise be diverted through their collection and diver- sion system. The exchange will be operated according to water year 1988 criteria during the period October 1, 1987, through September 30, 1988 (appendix B). i D. Turquoise Lake Inflow to Turquoise Lake for water year 1988 will be from four sources: Busk-Ivanhoe imports, Fryingpan-Arkansas Project imports, Homestake Project imports, and native flow of Lake Fork. Estimates of inflow from Busk-Ivanhoe and native Lake Fork ,were made using historical records and probabil ity analysis. Project water imports are estimated to be 3,000 acre-feet. Homestake will import ~pproximatelY 24,000 acre- feet of flow-through water for Otero pumping Pilant. The City of Colorado Springs and City of Aurora wi 11 probably refi 11 their allocated space after the peak runoff. . . 22
