<br />Water Year 1993 <br /> <br />Both Lakes Havasu and Mohave are scheduled to be drawn <br />down in the fall and winter months to provide storage space <br />for local storm runoff and will be filled in the spring to meet <br />higher summer water needs. This drawdown will also <br />correspond with maintenance at both Davis and Parker <br />Powerplants which is scheduled for September through <br />December. The normal filling pattern of these two reservoirs <br />coincides well with the fishery spawning period. <br /> <br />Lake Havasu is scheduled at the highest levels consistent with <br />the requirements for maintaining reservoir regulation space. <br />A yearly low elevation of approximately 446 reet is scheduled <br />for October through February to provide storage space for <br />local storm runoff. The ycarly high of aboul 450 feet is <br />scheduled in the spring to meet higher summer water needs. <br />During water year 1993, a total of approximately 6.7 million <br />acre-feet is scheduled to be released from Lake Havasu to <br />meet all downstream requirements. All of that amount is <br />scheduled to pass through the Parker Powerplant. <br /> <br />ACTUAL STORAGE 1992 <br /> <br />THOUSAND ACRe.
