3. Summary of Reservoir Levels and Contents Runoff7 during the year ending September 30, 2002 ranged from 35 percent of the long term (1927-02) mean at the Colorado River station near Cisco, Utah to 31 percent of the long term (1914-02) mean at the San Juan River station near Bluff, Utah. The volumes of runoff at these stations were 1,855,445 acre-feet and 535,926 acre-feet respectively. Runoff at the Green River station near Green River, Utah totaled 1,467,4 19 acre-feet, which was 33 percent of the long term (1906-02) mean. Lake Powell's lowest elevation of the 2002 water year occurred on September 30, 2002 when the reservoir level was at elevation 3626.53 feet (live content of 14,467,900 acre-feet). Lake Powell was at its highest point on October 1, 2001 at elevation 3,664.73 feet with a content of 19,120,000 acre-feet. A total of 8,230,900 acre-feet was released to the river below Glen Canyon Dam during the 2002 water year. The 1993-2002 (1 O-year) delivery to the Lower Basin (measured at Lee Ferry) was 102,255,000 acre-feet. Lake Mead, on September 30, 2002, contained 17,093,430 acre-feet8 of available storage water at elevation 1,155.42 feet. On September 30,2002, the live storage of Lake Mead was 2,024,000 acre-feet less than the storage in Lake Powell. Table 1 on page 11 shows the Statistical Data for Principal Reservoirs in the Upper Colorado River Basin. Table 2 on page 12 provides the same information for the Lower Colorado River Basin reservoirs. The results of the long-range reservoir operation procedures adopted by the Secretary of the Interior for Lake Powell, Flaming Gorge, Fontenelle, Navajo, and Blue Mesa reservoirs in the Upper Colorado River Basin and for Lake Mead in the Lower Basin are illustrated on pages 13 through 20 for the 2002 water year. In water year 2002, there was no equalization of storage as dictated by Section 602{a) of Public Law 90-537. The drawdown of Lake Powell was governed by factors other than the equalization criteria. 7 Adjusted for the change in storage in Colorado River Storage Project Reservoirs. 6 Based on April 1, 1967 Capacity Table revised according to Sedimentation Survey 1963-1964. 10
