<br />. <br /> <br />. <br /> <br />Commission to fashion a structure that better accomplishes the Commission's objectives. The <br />next hearing addressing the Resource Conservation and Environmental Protection sections of the <br />report is scheduled for September 17th in Fresno, California. A copy of the public hearing <br />schedule has been included in the Board folder for your information. I will continue to work <br />with the Agency Managers in developing an appropriate response strategy. <br /> <br />PROTECTION OF EXISTING RIGHTS <br /> <br />Colorado River Water Report <br /> <br />As of August 1, 2004, storage in the major Upper Basin reservoirs decreased by 529,200 <br />acre-feet and storage in the Lower Basin reservoirs decreased by 95,000 acre-feet during July. <br />Total System active storage as of August 19'h was 30.475 million acre-feet (maf) or 51 percent of <br />capacity, which is 4.188 maf less than one year ago. As of August IS', the surface elevation of <br />Lake Mead was at 1,125.73 feet above Mean Sea Level. <br /> <br />July releases from Hoover, Davis, and Parker Dams averaged 15,480, 14,950 and 11,890 <br />cubic feet per second (cfs), respectively. Planned releases from those three dams for the month <br />of August 2004 are 12,100, 12,100, and 10,800 cfs, respectively. The August releases represent <br />those needed to meet downstream water requirements including those caused by reduced <br />operation of Senator Wash Reservoir. <br /> <br />The final August 16, 2004, projected April through July 2004 unregulated inflow into <br />Lake Powell was 3.638 maf, which is 46 percent of the 30-year average for the period 1961- <br />1990. The final August 16,2004, projected unregulated inflow into Lake Powell for the 2004-05 <br />water year was 6.202 maf, or 52 percent of the 30-year average. <br /> <br />As of August 19th, taking into account both measured and unmeasured return flows, the <br />Lower Division States' consumptive use of Colorado River water for calendar year 2004, as <br />forecasted by Reclamation, totals 7.383 maf and is described as follows: Arizona, 2.803 maf; <br />California, 4.283 maf; and Nevada, 0.297 maf. The Central Arizona Project (CAP) will divert <br />1.604 maf, of which 0.308 maf are planned to be delivered to the Arizona Water Bank. The <br />Metropolitan Water District of Southern California (MWD) will use about 0.517 maf, which is <br />0.167 maf less than its actual use of mainstream water in 2003. <br /> <br />The preliminary end-of-year estimate by the Board for 2004 California agricultural <br />consumptive use of Colorado River water under the first three priorities and the sixth priority of <br />the 1931 California Seven Party Agreement is 3.694 maf. This estimate by the Board staff is <br />based on the collective use, through June 2004, by the Palo Verde Irrigation District, the Yuma <br />Project-Reservation Division (ypRD), the Imperial Irrigation District, and the Coachella Valley <br />Water District. Figure 1, found at the end of this report, depicts the historic projected <br />end-of-year agricultural use for the year. <br /> <br />2 <br />
