3. Summary of Reservoir Levels and Contents Runoff7 during the year ending September 30, 1996 ranged from 32.9 percent of the 83-year (1914-1996) mean at the San Juan River station near Bluff, Utah to 99.8 percent of the 83-year mean at the Colorado River station near Cisco, Utah. The volumes of runoff at these stations were 787,200 acre-feet and 5,556,800 acre-feet respectively. Runoff at the Green River station near Green River, Utah totaled 4,544,600 acre-feet, which was 98.4 percent of the 83-year mean. Lake Powell's lowest elevation of the 1996 water year occurred on April 3, 1996 when the reservoir level was at elevation 3,671.79 feet (live content of 20,086,800 acre-feet). Lake Powell was at its highest point on July 7, 1996 at elevation 3,688.31 feet with a content of 22,494,400 acre-feet. A total of 11,431,400 acre-feet was released to the river below Glen Canyon Dam during the 1996 water year. The 1987-1996 (1 O-year) deliv- ery to the Lower Basin (measured at Lee Ferry) was 91,351,000 acre-feet. Lake Mead, on September 30, 1996, contained 21,613,800 acre-feetB of available storage water at elevation 1,190.84 feet. On September 30, 1996, the live storage of Lake Mead was 458,700 acre-feet greater 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 1996 water year. In water year 1996, 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. · Based on April 1 ,1967 Capacity Table revised according to Sedimentation Survey 1963-1964. 10 j
