, 002JJ;l . . . , EXECUTIVE DIRECTOR'S MONTHLY REPORT TO THE COLORADO RIVER BOARD OF CALIFORNIA RECEIVEI"'l NOV 20 2000 November 14,2000 Colorado Waler Conserval:ioll l ADMINISTRATION Tentative Meeting Schedule for Calendar Year 2001 Included in the Board folder is a copy of the proposed meeting schedule for calendar year 2001. I would like the Board members to review it for possible conflicts and provide me with comments. I would note that there is onc apparent conflict dcaling with the August meeting coinciding with the NWRA Water Seminar in Skamania Lodge, Stevenson, Washington. The Board may want to consider moving off that date. I plan on asking for approval, of the meeting schedule at the Board's December meeting in Las Vegas, Nevada. PROTECTION OF EXISTING RIGHTS Colorado River Water Reoort During September 2000, storage in the major Upper Basin reservoirs decreased by 501,000 acre-feet and storage in the Lower Basin reservoirs decreased by 207,000 acre-feet. Total System active storage as of the end of September was 50.752 million acre-feet (mal) or 85 percent of capacity, which is 5.096 mafless than one year ago. October releases from Hoover, Davis, and Parker Dams averaged 9,570, 12,140 and 9,160 cubic feet per second (efs), respectively. Planned releases from those three dams for the month of November 2000 are 13,300, 10,300 and 6,900 cfs, respectively. The November releases represent those needed to meet downstream water requirements and to conduct dredging operations above More\os Dam. The preliminary observed April through July 2000 unregulated inflow into Lake Powel1 was 4.352 maf, which is 56 percent of the 30-year average for the period 1961-1990. The preliminary observed unregulated inflow into Lake Powel1 for the 1999-00 water year was 7.3 10 maf, or 62 percent of the 30-year average. The Lower Division states' estimated consumptive use of Colorado River water for calendar year 2000, as estimated by Board staff, totals 8.548 ffiaf and is projected as follows: Arizona, 2.873 maf; California, 5.376 maf; and Nevada, 0.299 maf. Estimated additional unmeasured return flow credits of 0.248 mafwould reduce the total amount to 8.300 maf. For calendar year 2000, the Central Arizona Project (CAP) is projected to divert 1.425 maf, of which 0.3 I 5 mafis to be credited to the Arizona Water Bank, and The Metropolitan Water District of Southern California (MWD) is projected to divert 1.302 maf. j
