<br /> <br />18 <br /> <br />a seven-year study of the habitat needs of the endangered fish in the San] uan <br /> <br />River Basin conducted by the United States Fish and Wildlife Service. After the <br /> <br />study period, the data collected will be used to the determine flow requirements for <br /> <br />these fish. The resulting flow requirements may be higher or lower than the flow <br /> <br />releases for 1992. <br /> <br />Lake Powell <br /> <br />Maintaining a minimum release of 8,230,000 AF annually from Lake Powell <br /> <br /> <br />combined with the lowest consecutive 5 years of inflow on record (1987 through <br /> <br /> <br />1991), and a refilling of the upstream reservoirs has reduced the storage of the <br /> <br /> <br />reservoir by approximately 9,500,000 AF. Lake Powell is expected to finish 1991 at <br /> <br /> <br />14,700,000 AF, which is 61 percent of capacity and about 71 feet from full. The <br /> <br /> <br />reservoir storage is projected to continue to decline through the fall and winter, <br /> <br /> <br />reaching a seasonal low in March of 1992 of 13,600,000 AF, which is about 82 feet <br /> <br /> <br />from full. <br /> <br />During water year 1992, the minimum objective release of 8,230,000 AF will be <br /> <br /> <br />made. Under most probable inflow conditions, the reservoir will recover to only <br /> <br /> <br />17,200,000 AF which is about 50 feet from full. Due to the extended drought, it <br /> <br /> <br />may take approximately nine years of average inflow to refill the reservoir. <br /> <br />
