2. Forecast of Stream Flow The April 3, 2002 forecast of inflow to Lake Powell by the National Weather Service, Department of Commerce, for April-July was estimated to be 3,000/000 acre-feet1. The actual unregulated inflow to Lake Powell for the period April-July 2002 amounted to 1,115,000 acre-feet2, which was about 14 percent of the 30-year (1961-1990) average flow. During the April-July 2002 period, changes in storage in Colorado River Storage Project reservoirs including Lake Powell resulted in an overall decrease of 2,091,900 acre-feet, with 222,490 acre-feet of evaporation and a 31,400 acre-feet increase in bank storage3. Actual regulated inflow to Lake Powell for the period April-July 2002 was 1,453,560 acre-feet. For the period October 1, 2001 through September 30, 2002, the change in reservoir storage, excluding bank storage and evaporation, at selected reservoirs above Lake Powell was as follows: . Fontenelle increased 82,700 acre-feet. . Flaming Gorge decreased 292/000 acre-feet. . Taylor Park decreased 24,300 acre-feet. . Blue Mesa decreased 320/500 acre-feet. . Morrow Point decreased 3,500 acre-feet. . Crystal increased 1/900 acre-feet. . Navajo decreased 536,100 acre-feet. The virgin flow4 of the Colorado River at Lee Ferry5 for the 2002 water year amounted to 6,518,000 acre-feet6. 1 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. 4 Virgin flow is the estimated flow of the stream if it were in its natural state and unaffected by the activities of man. 5 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. 9
