<br />. <br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />Charles A. Calhoun - Glen Canyon Dam Operations <br />September 23, 1994 <br />Page 3 <br /> <br />the illegality of reducing "flood control space," is confirmed by <br />the report of the Committee on Energy and Natural Resources, United <br />States Senate, to accompany H.R. 429, printed March 31, 1992. This <br />committee report accompanied the Senate version of H.R. 429, which <br />is the version which was passed by Congress. The Senate Committee <br />report states: <br /> <br />The primary purpose of Glen Canyon Dam as part of the <br />larger CRSP system is to enable the states of Utah, <br />Colorado, Wyoming, and New Mexico to utilize their <br />apportionment of Colorado River water and to meet their <br />obligations for water delivery to the states of Arizona, <br />California, and Nevada. Lake Powell and other CRSP <br />reservoirs allow the Upper Basin States to take water <br />year-round from the Upper Colorado River for consumptive <br />uses and still store enough spring runoff in Lake Powell <br />to guarantee the required compact deliveries to the Lower <br />Basin States even during a long period of drought. <br /> <br />The operation of Glen Canyon Dam is controlled by the <br />Bureau of Reclamation to meet project purposes. The <br />maior operational qoals for Glen Canvon Dam are water <br />storaqe and deliverv to the Lower Colorado River Basin, <br />consistent with the laws, treaties, compacts, and court <br />decisions regarding Colorado River operations, <br />collectively known as the "Law of the River." <br /> <br />Operation of Glen Canyon Darn has been established through <br />a two-fold procedure. First, the Secretary of Interior <br />annually determines volumes of water to be stored and <br />released for international treaty and interstate compact <br />purposes. Annual and month Iv release volumes are based <br />uPon water supplv considerations. water deliverv <br />requirements. and the avoidance of anticipated spills <br />from Lake Powell ('spills' being releases in excess of <br />power plant capacity, which releases are referred to as <br />'flood releases'). Annual and monthly reservoir <br />operations are governed by, among other things, the <br />Mexican Water Treaty, the Colorado River Compact, Title <br />VI of the Colorado River Basin Project Act of 1968 <br />(hereinafter the '1968 Act'), and the 'Criteria for <br />Coordinated Long-Range Operation of Colorado River <br />Reservoirs' (hereinafter 'Coordinated Long-Range <br />Operating Criteria') promulgated pursuant thereto in <br />1970. These operational constraints take precedence over <br />power operations (as is provided for by Section 1 of the <br />Colorado River storege Project Act of 1956 <br />(hereinafter'1956 Act') and by Section 602(c) of the 1968 <br /> <br />\ <br />
