<br />. <br /> <br />-- .' <br /> <br />The final June 6th forecast for April through July unregulated inflow to Lake Powell is <br />12.200 maf, which is 158 percent of the 30-year average for the period 1961-1990. The inflow to <br />Lake Powell for the 1996-97 water year is expected to be 16.799 maf, or 143 percent of the 30-year <br />average. <br /> <br />The Lower Division states' estimated consumptive use of Colorado River water for calendar <br />year 1997, as estimated by Board staff, totals 8.459 maf and is projected as follows: Arizona, 2.989 <br />maf; California, 5.210 maf; Nevada, 0.260 mat: Estimated additional unmeasured return flow credits <br />of 0.262 maf would reduce the total amount to 8.197 maf. For calendar year 1997, the Central <br />Arizona Project (CAP) is projected to divert 1.477 maf and The Metropolitan Water District of <br />Southern California (MWD) 1.245 maf. <br /> <br />The preliminary June 3rd estimate of the 1997 end-of-year California agricultural <br />consumptive use of Colorado River water under the first three priorities of the 1931 California Seven <br />Party Agreement is 3.906 maf. This estimate is based on the collective use through May 1997 by <br />the Palo Verde Irrigation District, the Yuma Project Reservation Division, the Imperial Irrigation <br />District, and the Coachella Valley Water District. Figure 1, bound at the end of this report, depicts <br />the monthly forecasts of end-of-year agricultura1 use since the beginning of the year. <br /> <br />Colorado River Operations <br /> <br />Last month I reported that Reclamation had released an initial draft of the 1998 Annual <br />Operating Plan for the Colorado River System Reservoirs (1998 AOP) and was accepting comments <br />on the initial draft through May 16th. Included in the Board folder are copies of some of the <br />comments received by Reclamation from: 1) the Central Arizona Project Association; 2) the Imperial <br />Irrigation District; and 3) the MWD. The next meeting of the Colorado River Management Work <br />Group will be held on June 20,1997, in Las Vegas, Nevada to review the draft 1998 AOP. <br /> <br />As discussed during previous Board meetings, Reclamation has undertaken an effort to <br />develop guidelines for declaring surplus and shortage conditions on the River. Several different <br />operating strategies were run by Reclamation to determine the impacts associated with each strategy. <br />During a JWle 3rd meeting held in Las Vegas, Nevada, Reclamation discussed the strategies that had <br />been run as well as the results of each strategy. Those strategies that were tested include: I) flood <br />control, 70 percentile runoff volume into Lake Powell, 70 percent avoidance of a spill at Lake Mead, <br />80 percent protection of the shortage trigger, and basin yield. Reclamation will be accepting <br />comments on the strategies through July 1, 1997. <br /> <br />The Water Education FOWldation sponsored a symposium to celebrate the 75th anniversary <br />of the signing of the Colorado River Compact. The symposium was held at Bishop's Lodge in <br />Santa Fe, New Mexico, the site of the signing of the 1922 Colorado River Compact. All of the <br />agencies, except the Los Angeles Department of Water and Power attended the symposium and <br />made presentations. <br /> <br />2 <br />
