Show VI-66 UPDATING THE HOOVER DAM DOCUMENTS COLORADO RIVER STORAGE PROJECT 61 assuming an over-all efficiency of 83 percent, would have been generated und delivered at transmission voltage at Hoover Power Plant in that year if water had not been impounded in the reservoirs of the Colorado River Storage Project storage units (Glen Canyon, Flaming Gorge, Navajo and Curecanti), [but excluding] including the effects of evaporation from the surface of such reservoirs, and.the energy actually generated and delivered at transmission voltage at Hoover Power Plant during that year adjusted to reflect an over-all efficiency of S3 percent. At the discretion of the Secretary, allowance will be accomplished by the United States delivering energy, either at Hoover Power Plant or at points and at times acceptable to both the Secretary and the affected Hoover power contractors, or monetarily in an amount equal to the replacement incremental cost of securing a substitute supply ojcapacity and en erg v. ITo the extent the Upper Colorado River Basin Fund is utilized the moneys expended therefrom in accomplishing the allowance, either through the delivery of purchased energy or by direct monetary payments, shall be reimbursed to said Fund from the Separate Fund identified in Sec. 5 of the Act of December 21, 1928 (45 Stat. 1057), to the extent such reimbursement is consistent with the expenditures Congress may authorize from said Separate Fund pursuant to said Act. The attached Additional Regulation No. 1 for Generation and Sale of Power in accordance with the Boulder Canyon Project Adjustment Act is hereby made a part of these principles and criteria.] 6. In accomplishing the foregoing, Lake Powell will be operated in general accordance with the provisions of Principles 7 and 8. 7. Storage capacity in Lake Powell to elevation 3,4,90 (6.5 million acre-feet surface storage) shall be obtained at the earliest practicable time in accordance with the following procedure: Until elevation 3,490 is first reached, any water stored in Lake Powell shall be available to maintain rated head on Hoover Power Plant. When stored water in Lake Powell has reached elevation 3,490, it will not be subject to release or diminution below elevation 3,490. The obtaining of this storage level in Lake Powell will be in such manner as not to cause Lake Mead to be drawn down below elevation 1,123 (14.5 million acre-feet available surface storage), which corresponds to rated head on the Hoover Power Plant. In the process of gaining storage to elevation 3,490, the release from Glen Canyon Dam shall not be less than 1.0 million acre-feet per year and 1,000 cubic feet per second, as long as inflow and storage will permit. 8. The operation of Lake Powell above elevation 3,490 and Lake Mead will be coordinated and integrated so as to produce the greatest practical amount of power and energy. Any water stored in Lake Powell above elevation 3,430 shall be subject to release to maintain rated head on Hoover Power Plant. In view of the provision for allowance set forth in Principle 5 hereof, the quantity of water released through each power plant will be determined by the Secretary in a manner appropriate to meet the filling criteria. 9. In general, it is not anticipated that secondary energy will be generated at Hoover during the filling period. However, any secondary energy, as defined in the Hoover contracts, which may be generated and delivered at transmission voltage at Hoover Power Plant will be disposed of under the terms of such contracts. 95968-63------6 |
