<br />-, <br /> <br />3 <br /> <br />be primarily a source of augmentation water. When releases are made from the <br />proposed reservoir in exchange for water stored in Green Mountain Reservoir. <br />those releases would be controlled by the Reclamation as though the water were <br />stored in Green Mountain Reservoir. <br /> <br />Although intended to serve West Slope interests, water from a reservoir at <br />Muddy Creek would be marketed to the Denver Water Board in the short term <br />(25 yearsl. The short-term operational scenario was formal ized under a <br />December 1986 Denver Water Board-River District Agreement. That agreement <br />would allow ~ddy Creek to be operated to fulfill the following four primary <br />demands under the lease with the Denver Water Board: <br /> <br />1. Supply one-half of the Green Mountain natural fill deficit during dry <br />years (approximately 5 out of 30 years under present development <br />conditions and as often as 12 out of 30 years with full development of <br />East Slope storage) when Williams Fork Reservoir exceeds 65,000 acre- <br />feet. This demand would come primarily in August and September. after <br />Reclamation has determined that Green Mountain will not achieve its <br />legal fill from the intervening inflow between Dillon and Green <br />Mountain. This release would offset releases from Dillon Reservoir. <br />The other 50 percent of the fill deficit would be supplied by Williams <br />Fork Reservoi r, as was done in 1977. When Wi 11 i ams Fork Reservoi r is <br />below 65.000 acre-feet. the entire Green Mountain fill deficit would be <br />supplied (up to the terms of the lease). Under the terms of the Denver <br />Water Board-River District Agreement, this demand could not exceed <br />30.000 acre-feet in any given year. or 45,000 acre-feet any 3 years. <br /> <br />2. Supply the water necessary to make up Green Mountain water operation <br />shortages to permit full util ization of the 100.000 acre-foot pool. <br /> <br />3. Provide for 2,000 acre-feet of water supply for Middle Park Water <br />Conservancy District, as required by the Intergovernmental Agreement. <br /> <br />4. Provide for augmentation releases out of Muddy Creek Reservoir of up to <br />100 cfs during August, September. and October in Muddy Creek and the <br />Colorado River. The availability of these releases would be dependent <br />upon storage in the reservoi r. but they cou 1 d be used for a vari ety of <br />e~elent purposes (e.g., endangered fishes. recreation. and aquatic <br />habitat). <br /> <br />The Denver Vater Board-River District Agreement has a term of 25 years. After <br />the lease expires, the yield of Muddy Creek Reservoir could be used to meet West <br />Slope water ~. could continue to be leased to Denver. or could be used for a <br />conbinatfon of these needs. A scenario consisting primarily of of! shale demand <br />provides the lOSt reasonable projection of West Slope needs 25 years in the <br />future. ~ Creek Reservoir would be operated to fulfill the following four <br />primary demands under a West Slope scenario: <br />
