REPORT ON OPERATIONS DURING WATER YEAR 1990 <br /> <br />A. Ruedi Reservoir <br /> <br />Ruedi Dam is located on the Fryingpan River on Colorado's western slope. <br />The reservoir provides replacement storage for out-of-priority depletion by <br />the Project. Additional storage water is available for sale to meet <br />irrigation and municipal and industrial water needs in western Colorado. <br /> <br />The reservoir has a total capacity of 102,300 acre-feet. The spillway on <br />the right abutment is uncontrolled with an ogee-type crest which has a total <br />release capability of 5,500 ft3/s. <br /> <br />Storage in Ruedi Reservoir at the beginning of water year 1990 <br />(September 30, 1989) was below capacity at 89,720 acre-feet which is <br />96 percent of normal. On October 1, the reservoir release was at 190 ft3/s <br />to bypass native inflow and continue the 'endangered fish release. This <br />relea~e rate was maintained until October 17 when it was decreased to <br />80 ft Is. The maximum daily release occurred during the first 16 days of <br />October at 190 ft3/s. The maximum reservoir content reached during the year <br />was 101,270 acre-feet on July 27. The 101,270 acre-feet is 1,100 acre-f~et <br />less than conservation capacity. Maximum inflow for the year of 680 ft Is <br />occurred on June 10. <br /> <br />During water year 1990, requests were made for releases of stored water by <br />West Divide and 8asalt Water Conservancy Districts. Total release for the <br />two storage entities was approximately 174 acre-feet. West Divide useage <br />was about 54 acre-feet, and Basalt Water Conservancy District used <br />120 acre-feet. Both entities called for their releases from July 30, 1990, <br />through October 24, 1990 (table 1). In addition to the releases for the two <br />storage contract entities, a release of 10,000 acre-feet was made from <br />August 14, 1990, through November 3, 1990 for the U.S. Fish and Wildlife <br />Service from water leased by the Colorado Water Conservation Board. The <br />release was for the enhancement of endangered fish, in the Colorado River's <br />"IS-mile reach" just below the Grand Valley Diversion Dam near Grand <br />Junction, Colorado. Also included in tabl,e 1 .is the release for endangered <br />fish for 1989. Both the 1989 and 1990 releases extended into the next water <br />year but are being published in their entirety to show the total volume of <br />the release. The content in Ruedi Reservoir on September 30, 1990, was <br />92,300 acre-feet or 99 percent of normal. <br /> <br />Exhibits 1 and 2 show the precipitation ,and pan evaporation at Meredith. <br />Table 2 and exhibit 3 show the operations of Ruedi Reservoir during water <br />year 1990. Table 3 and 4 show the daily release for endangered fish for <br />water years 1989 and 1990. Also shown is the storage release for irrigation <br />and M&I under augmentation plans for both West Divide and Basalt Water <br />Conservancy District during the month of August through October. <br /> <br />B. West SloDe Collection System <br /> <br />The Project imports during water year 1990, as measured at Charles H. <br />Boustead Tunnel (Boustead Tunnel) outlet were 46,610 acre-feet. {see <br />
