'. . . ., PROTECTION OF EXISTING RIGHTS Colorado River Water Reoort During June 2001, storage in the major Upper Basin reservoirs increased by 506,000 acre-feet and storage in the Lower Basin reservoirs decreased by 542,000 acre-feet. Total System active storage as of the end of June was 48.585 million acre-feet (maf) or 81 percent of capacity, which is 4.696 maf less than one year ago. July releases from Hoover, Davis, and Parker Dams averaged 16,280, 16,300 and 13,240 cubic feet per second (cfs), respectively. Planned releases from those three dams for the month of August 2001 are 14,390, 13,190 and 10,390 cfs, respectively. The August releases represent those needed to meet downstream water requirements including those caused by reduced operation of Senator Wash reservoir. The August 1,2001 final forecast of the unregulated inflow into Lake Powell reported that the observed April through July 2001 flow into Lake Powell was 4.30 maf, which is 56 percent of the 30- year average for the period 1961-1990. The forecast of unregulated inflow into Lake Powell for the 2000-200 I water year is 6.954 maf, or 59 percent of the 30-year average. The Lower Division States' estimated conswnptive use of Colorado River water for calendar year 200 1, as estimated by Board staff, totals 8.238 maf and is projected as follows: Arizona. 2.842 mat California, 5.087 maf; and Nevada., 0.308 maf. Estimated additionallinmeasured return flow credits of 0.228 mafwould reduce the total amount to 8.010 maf. For calendar year 2001, it is estimated the Central Arizona Project (CAP) will divert 1.557 maf, of which 0.311 maf is to be credited to the Arizona Water Bank, and The Metropolitan Water District of Southern California (MWD) will divert 1.233 mar The preliminary August I estimate of200 I end-of-year California agricultural conswnptive use of Colorado River water under the first three priorities and the sixth priority of the 1931 California Seven Party Agreement is 3.806 maf. This estimate is based on the collective use through July 2001 by the Palo Verde Irrigation District (PVID), the Ywna Project Reservation Division (YPRD), the Imperial Irrigation District (lID), and the Coachella Valley Water District (CVWD). Figure I, found at the end ofthis report, depicts the historic projected end-of-year agricultural use for the year.

When compared to previous drafts of the 2002 AOP, only editorial changes have been made. The recommended Secretarial determinations remained unchanged. 2
