(d~ ,. 'S .', iJ - . acre-feet. Project water equal to minimum imports (18,000 acre-feet) was con- sidered delivered to the Southeastern Colorado Water Conservancy District in August and September. Turquoise storage releases were consideredthe same under allthreeinflow con- ditions to the extent water was available for release, Native flow bypass varies with native inflow under the three conditions, Under minimum inflow conditions, the proj ect ownership at the end of water year 1972 would be 13,500 acre-feet. Water for the inactive pool in Pueblo Reservoir is not required until the fall of 1973. Therefore, an additional season of imports will be available to accomplish this purpose. Under most probable conditions, the plan shows 29,500 acre-feet in project ownership at the end of water year 1972. By the fall of 1973, 39,000 acre-feet will be required to fill the inactive pools. From the above, it is apparent that a reassessment of the sale of water to the Conservancy District may be necessary if the reasonable minimum inflow and imports materialize and the present construction schedule is maintained, A more probable estimate of the volume available for sale is 5, 000 acre-feet. Table 4 is a tabulation of the water year 1972 proposed operation of Turquoise Lake, and exhibit 6 is a graph of this operation. . Western Slope Collection System It was anticipated in last year's Annual Operating Plan that 1971 would mark the first importation of water from the western slope. Lining of the Charles H. Boustead Tunnel was not completed during the 1971 runoff season and the im- portation was not realized. May 1972 will probably be the date of the first diver- sion of Fryingpan River water to the Arkansas River basin through the Charles H, Boustead Tunnel. There are only three diversion points complete on the western slope, these are Chapman Gulch, South Fork of the Fryingpan River, and Fry- ingpan River and Marten Creek. Present plans call for making fish bypass from these three points in proportion to each point's share of the entire collection system. For planning purposes, data from our collection system yield and sizing studies were used to determine the diversions in 1972. Data from these studies indicate diversions would meet the requirements for proportional fish bypass at the collection system, but would be somewhat conservative at those times when the fish requirement at Norrie controlled, as the untapped portion of the collec- tion system would undoubtedly make up the required fish flow at that point. . 16
