<br />o <br />C.) <br />(-) <br />en <br />(J) <br />l-" <br /> <br /> <br />The reservoir has a total storage capacity of 153,639 af, with a dead storage of 6,860 af. It has <br /> <br /> <br />an original storage right of 154,645 af and a refill right of 6,316 af. The operating policy of Green <br /> <br /> <br />Mountain Reservoir is set forth in Senate Document No. 80 (Act of August 9, 1937, 50 Stat. 564) and <br /> <br /> <br />reaffirmed in subsequent court decrees and stipulations including: <br /> <br /> <br />o Consolidated Cases (Civil Actions) Nos. 2782,5016, and 5017 <br /> <br />o October 12, 1955 Stipulation and Decree <br /> <br /> <br />o April 16, 1964 Stipulation and Decree <br /> <br />o November 2, 1977 Memorandum Opinion and Order <br /> <br />o February 9, 1978 Supplemental Judgment and Decree <br /> <br />Senate Document No. 80 specifies that 52,000 af of storage in the Green Mountain Reservoir <br /> <br /> <br />is to be reserved to supply replacement water to the Colorado River for out-of-priority CBT project <br /> <br />diversions. The balance of the storage, about 100,000 af, is to be used primarily for power <br /> <br />generation and for irrigation and domestic uses in western Colorado which are not satisfied by <br /> <br />natural flows. Under Senate Document No. 80, one of the uses of the Reservoir in such <br /> <br />circumstances, Is to augment irrigation and domestic uses that existed in 1937 and, to the extent <br /> <br />storage water Is thereafter available for release, to augment similar needs which subsequently arise. <br /> <br />To meet these needs, the Reservoir has been operated to maintain a flow of about 1250 cfs during <br /> <br />the irrigation season at the Dotsero gage in Glenwood Canyon. Approximately 66,000 af of water was <br /> <br />released from storage in 1977 to supplement natural flow shortages in western Colorado (USBR, <br /> <br />1963-1982). <br /> <br />The water rights for Green Mountain Reservoir have a priority date of 1935, and are senior to <br /> <br /> <br />those of Roberts Tunnel and Dillon Reservoir, which are Denver's Blue River diversion. A <br /> <br /> <br />combination of the 1955 and 1964 Stipulations and Decrees provided that, upon approval of the <br /> <br /> <br />Secretary of Interior, Denver can store out-of-priority water in Dillon Reservoir during the spring <br /> <br />snowmelt .runoff season. This out-of-priority storage is permitted on the condition that if Green <br /> <br /> <br />Mountain Reservoir does not fill, water would be released later to satisfy the fill requirement of <br /> <br />Green Mountain Reservoir. Water can be released either from Dillon Reservoir to flow into Green <br /> <br /> <br />Mountain Reservoir, or from Williams Fork Reservoir to meet the Green Mountain Reservoir release <br /> <br /> <br />obligations. Another condition was that energy lost to the Green Mountain Power Plant because of <br /> <br /> <br />reduced flow, would be replaced in kind. <br /> <br />3-4 <br />
