Navajo Reservoir (San Juan River) Skiing Navajo Reservoir. WaterYear 1981 During the first part of water year 1 981. a minimum 530 'PIs was released tor consumptive use and maintenance of fish and wildlife, The April-July 1981 inflow was 320.000 acre- feel, which is 45 percent of Ihe long-term average. During the water year, the maximum inflow of 3,670 f1"s occurred on June 11, At the beginning of the water year, the reservoir elevalion was 6.075 feet. 11 gradually was drawn down to 6.050 feet prior to the spring runoff. The water surface reached its highest elevation of 6,060 feet during June 1981, 12 Water Year 1982 On September 30, 1981. Navajo Reservoir stored 1 ,248,000 acre-feet of water at an elevation of 6.052 leet, Assuming average inflow for water year 1982, the projected elevation before snowmelt runoH begins is 6,050 feet with a content of 1 ,221 ,000 acre- feet. By July 1982. the reservoir is expected to reach an elevation of 6,074 feet with a content of 1,534.000 acre-feet. This approximate elevation will be maintained throughout the summer to enhance recreational use. Releases from Navajo Reservoir for an upper quartile inflow are projected to average 700 ft'/s during the winter and increase to a maximum of 2,000 fP/s during the summer, For an average inflow, releases are expected to be about 530 ft'/s through the winter. then increase 10 a maximum of approximately 1.500 ft"s durin9 the summer, The lower quartile and most adverse releases are projected to average about 530 ft'ls throughout the water year.
