2. Forecast of Stream Flow The April 1, 1996 forecast of inflow to Lake Powell by the National Weather Service, Department of Commerce, for April-July was estimated to be 8,900,000 acre-feet'. The unregulated inflow to Lake Powell for the period April-July 1996 amounted to 7,322,000 acre-feef, which was about 95 percent of the 30-year (1961-1990) average flow. During the April-July 1996 period, changes in storage in Colorado River Storage Project reservoirs including Lake Powell resulted in an overall increase of 2,636,100 acre-feet, with 288,600 acre-feet of evaporation and a 253,200 acre-feet increase in bank storage3. Actual regulated inflow to Lake Powell for the period April-July 1996 was 6,627,000 acre-feet. For the period October 1, 1995 through September 30, 1996, the change in reservoir storage, excluding bank storage and evaporation, at selected reservoirs above Lake Powell was as follows: . Fontenelle decreased 36,300 acre-feet. . Flaming Gorge decreased 124,200 acre-feet. . Taylor Park decreased 19,200 acre-feet. . Blue Mesa decreased 95,600 acre-feet. . Morrow Point increased 800 acre-feet. . Crystal decreased 800 acre-feet. . Navajo decreased 352,800 acre-feet. The virgin flo~ of the Colorado River at Lee Ferri for the 1996 water year amounted to 14,185,000 acre-feer. , Including water to be stored upstream in other Colorado River Storage Project Reservoirs. 2 Adjusted for upstream regulation and depletions. 3 Includes Flaming Gorge Reservoir on the Green River. · Virgin flow is the estimated flow of the stream if it were in its natural state and unaffected by the activities of man. 6 Lee Ferry, Arizona is the division point between the upper and lower basins of the Colorado River as defined in the Colorado River Compact. It is located about one mile downstream from the mouth of the Paria River and about 16 miles downstream from Glen Canyon Dam. 6 Based on provisional records subject to revision. l 9
