<br />Lake Mohave (Colorado River) <br /> <br /> <br />Water Year 1985 <br />At the beginning of water year 1985, the <br />water surface elevation of Lake Mohave, <br />which is impounded by Davis Dam, was <br />638.6 feel. with an active storage of <br />about 1.578.000 acre.feet. <br /> <br />Dunng the winter months, the water level <br />was gradually lowered to approximately <br />633 feet, with an active storage of about <br />1,450,000 acre. feet by the latter part of <br />December 1984. The water level was <br />then gradually raised during the remain. <br /> <br /> <br />ing winter months. The reservoir reached <br />elevation 644 feet by the end of February <br />1985. During the month of April, Lake <br />Mohave reached a high elevation of 646 <br />feet, with an active storage of about <br />1,800,000 acre. teet. The reservoir ended <br />the water year at an elevation of 637.9 <br />feet with 1,560,000 acre.feet in active <br />storage. <br /> <br />Lake Mohave releases were made to <br />satisfy flood control requirements and <br />downstream water use requirements, <br />including diversions by The Metropolitan <br />Water District of Southern California <br />(MWD). A small amount of reregulation <br />occurred at Lake Havasu. During the <br />water year, approximately 18,687,000 <br />acre-feet were released at Davis Dam. Of <br />that amount, approximately , 6,350,000 <br />acre-feet passed through the turbines for <br />power production. <br /> <br />Waler Year 1986 <br />Under most probable inflow conditions <br />the water level of Lake Mohave is <br />scheduled to reach an elevation of 643 <br />feet by the end of February 1986 and <br />vary around that elevation for the <br />remainder of the water year. During the <br />water year a total of 12.7 million acre.feet <br />is scheduled to be released from Lake <br />Mohave to meet all downstream and <br />flood control requirements. All of that <br />total is scheduled to pass through the <br />powerplant. <br /> <br />Lake Mohave Active Storage" Chart 7 <br /> <br /> Reservoir Acre-Feet EI.
