<br />Water Year 1990 <br /> <br />Both Mohove and Havasu Reservoirs are scheduled to be <br />drawn down in thewinter months to provide storage space for <br />local storm runoff and will be filled in the spring to meet higher <br />summer water needs, This drawdown will also correspond <br />with maintenance at both Davis and Parker Powerplants <br />which is scheduled for September through December, The <br />normal fdling pattern of these two reservoirs coincides well <br />with the fIShery spawning period, Since elevations of both <br />reservoirs will be typical of previous years, normal conditions <br />are expected for boating and other recre.ational uses, <br /> <br />Under most probable inflow conditions the water level of <br />Lake Mohave is scheduled to reach an elevatioo of about <br />643 feet by the end of January 1990 and then rise to elevation <br />645 feet by the end of May, The reservoir will gradually drop <br />to an elevation of approximately 630 feet by the end of the <br />water year. During the water year a total of 8,7 mal is <br />scheduled to be released from Davis Dam powerplant to meet <br />all downstream requirements, <br /> <br />LAKE MOHAVE STORAGE <br /> <br />1000 ACRE..ofEET <br />1000 <br /> <br />1700 <br /> <br /> <br />1000 <br /> <br />"00 <br /> <br />1400 <br /> <br />,"00 <br /> <br />1100 <br /> <br />1100 <br /> <br />tOOO <br />o N a J F W A W J J A 8 Q N D J F M A M J J A 8 0 <br />ACTU"~ 1989 AND PROJECTED 1990 <br /> <br />PROJECTED OPERATION 1990 <br />REASONABLE.
