Show VH-6 UPDATING THE HOOVER DAM DOCUMENTS (2) If in the plan of operation, either: (a) the Upper Basin Storage Reservoirs active storage forecast for September 30 of the current year is less than the quantity of 602(a) Storage determined by the Secretary under Article 11(1) hereof, for that date; or (b) the Lake Powell active storage forecast for that date is less than the Lake Mead active storage forecast for that date: the objective shall be to maintain a minimum release of water from Lake Powell of 8.23 million acre-feet for that year. However, for the years ending September 30, 1971 and 1972, the release may be greater than 8.23 million acre-feet if necessary to deliver 75,000,000 acre-feet at Lee Ferry for the 10-year period ending September 30, 1972. (3) If, in the plan of operation, the Upper Basin Storage Reservoirs active storage forecast for September 30 of the current water year is greater than the quantity of 602(a) Storage determination for that date, water shall be released annually from Lake Powell at a rate greater than 8.23 million acre-feet per year to the extent necessary to accomplish any or all of the following objectives: (a) to the extent it can be reasonably applied in the States of the Lower Division to the uses specified in Article IH(e) of the Colorado River Compact, but no such releases shall be made when the active storage in Lake Powell is less than the active storage in Lake Mead, (b) to maintain, as nearly as practicable, active storage in Lake Mead equal to the active storage in Lake Powell, and (c) to avoid anticipated spills from Lake Powell. (4) In the application of Article 11(3) (b) herein, the annual release will be made to the extent that it can be passed through Glen Canyon Powerplant when operated at the available capability of the powerplant. Any water thus retained in Lake Powell to avoid bypass of water at the Glen Canyon Powerplant will be released through the Glen Canyon Powerplant as soon as practicable to equalize the active storage in Lake Powell and Lake Mead. (5) Releases from Lake Powell pursuant to these criteria shall not prejudice the position of either the upper or lower basin interests with respect to required deliveries at Lee Ferry pursuant to the Colorado River Compact. ///. OPERATION OF LAKE MEAD (1) Water released from Lake Powell, plus the tributary inflows between Lake Powell and Lake Mead, shall be regulated in Lake Mead and either pumped from Lake Mead or released to the Colorado River to meet requirements as follows: (a) Mexican Treaty obligations; (b) Reasonable consumptive use requirements of mainstream users in the Lower Basin; (c) Net river losses; (d) Net reservoir losses; (e) Regulatory wastes. (2) Until such time as mainstream water is delivered by means of the Central Arizona Project, the consumptive use requirements of Article III(l) (b) of these Operating Criteria will be met. |
