PROTECTION OF EXISTING RIGHTS Colorado River Water Reoort During January 1997, storage in the major Upper Basin reservoirs decreased by 623,000 acre- feet and storage in the Lower Basin reservoirs increased by 279,000 acre-feel. Total System active storage at the end of January was 49.745 rnillion acre-feet (mat) which is 892,000 acre-feet less than one year ago. February releases from Hoover, Davis, and Parker Dams averaged 19,290, 18,640 and 14,210 cubic feet per second (cfs), respectively. Planned releases from those three dams for the month of March are 18,500, 17,590, and 13,910 cfs, respectively. Both February releases and the March planned releases represent downstream water requirements plus scheduled extra water releases started on January 17th to fulfill flood-control space building requirements. The March 3rd forecast for April through July unregulated inflow to Lake Powell is 13.200 maf, which is 171 percent of the 30-year average for the period 1961-1990, The inflow to Lake powell for the 1996-97 water year is expected to be 17.700 maf, or 151 percent of the 30-year average. The Lower Division states' estimated consumptive use of Colorado River water for calendar year 1997, as estimated by Board staff, totals 8.3 72 maf and is projected as follows: Arizona, 2.955 maf; California, 5,156 maf; Nevada, 0.261 maf. Estimated additional unmeasured return flow credits of 0.272 maf would reduce the total amount to 8,100 maf. For calendar year 1997, the
