<br />000732 <br /> <br />2.3.12 Municipal Recreatiori Agreement <br /> <br />The June 19,2001 Municipal Recreation Agreement Between the United States, the Town of Palisade, <br />the City of Grand J unction, and the City of F ruita allows for a release of HUP Surplus water to be <br />made from Green Mountain Reservoir for municipal recreational purposes if: <br /> <br />. HUP Surplus water is not needed to generate power at the Grand Valley Power Plant, <br /> <br />. Target flows for recovery of the endangered fishes in the 15-Mile Reach, as specified in <br />USFWS (May 1995, p. 65), are not being met and <br /> <br />. Sufficient HUP Surplus water exists to make the release. <br /> <br />Releases of Green Mountain Reservoir HUP water for municipal recreational purposes generally begin <br />in approximately mid-August and can continue into the fall. <br /> <br />StateMod and the Cl Data Set, C1 Data Set First Revision and the C1 Data Set Second Revision do <br />not model releases ofHUP Surplus water under the Municipal Recreational Agreement. The C1 Data <br />Set Third Revision (and subsequent revisions), however,. do permit release of Surplus HUP water <br />under the Municipal Recreation Agreement (see Table 2). <br /> <br />l<i.if! <br /> <br />2.3.13 Green Mountain Reservoir Accounting and Administration <br /> <br />The Accounting Principles for Green Mountain Reservoir (Revised Draft, April 21, 1994) include <br />three categories of reservoir fill: <br /> <br />. Physical Fill. "A physical fill of Green Mountain Reservoir (GMR) is achieved when <br />the actualwater surface reaches an elevation of 7,950.0 feet. The contents of GMR at <br />7,950 feet are 153,639 acre-feet. This includes 40,845 acre-feet of storage capacity at <br />elevation 7,870 feet, designated the minimum power pool, and 112,794 acre-feet of <br />active conservation capacity. The minimum power pool consists of 6,860 acre-feet of <br />dead storage at elevation 7,800 feet and 33,985 acre-feet of inactive storage. The <br />power plant generating units cannot generate electrical energy if the water surface of <br />the reservoir falls below elevation 7,870 feet. Water can be released through the river <br />outlet when the contents of GMR are below elevation 7,870 feet and above elevation <br />7,800 feet." <br /> <br />A reservoir fill accordin~ to the criteria of the Division 5 Engineer. "The sum of the <br />(a) water actually stored in GMR since the initiation of storage (between April 1 and <br />May 15 of each year), (b) releases of inflow since the initiation of storage (between <br />April 1 and May 15 of each year) to replace depletions of Senate Document No. 80 <br />beneficiaries, including contractors, who are subject to any "call" on the Colorado <br />River by an appropriator junior to August 1, 1935 greater than 60 cfs (amount that <br />satisfies operating criteria provisions including downstream rights on the Blue River <br />senior to August 1, 1935), (c) releases of inflow greater than (b) that bypass the power <br />plant, (d) depletions caused by Senate Document No. 80 beneficiaries, including <br /> <br />. <br /> <br />II <br /> <br />P: \Data \GEN\CWCB\19665\Repon Phase 2\FinalRepon12,Q2\Final_ Draf( Repon(l-03).doc <br /> <br />25 <br />
