<br />LAKE HAVASU <br />(COLORADO RIVER) <br /> <br /> <br />Water Year 1988 <br /> <br />At the begiJllling of water year 1988, the w~ter level of Lake <br />Hav~su. impounded by Parker Dam, was at an elevation of <br />about 448 feet with an active sll,lrage of about <br />570,000 acre-feet. During OctQQer, N\lvember, and <br />December 1987, the reservoir fluctuated between eleva,tion <br />446 feet and 448 feel. By mid-March 1988, the reservoir was <br />at an approximate elevation of 446 feet tei provi<le vacant <br />space for runoff from the drainage area between Davis alId <br />Parker Darns. The water level was then raised tOllD elevation <br />of 450 leet near the end of Apri~ with an ilctive storage of <br />about 615,000 ~cre-feet. At the end of the water year, <br />Lake Havasu was at an elevation of approximately 447 feet <br />with an active storage of 565,000 acre-feet. <br /> <br />ACTUAL RELEASES <br /> <br />WY 1988 <br /> <br />1000 CFa <br />.. <br /> <br />2' <br /> <br />2. <br /> <br />'.....,..,..,..,. 1. <br />.

That total release amount <br />included releases from Alamo Dam on the Bill Williams <br />River. In addition to the releases from Parker Dam, <br />approximately 1,207,000 acre-feet was diverted from <br />Lake Havasu by MWD. Diversions from Lake Havasu for the <br />CAP were 490,000 acre-feet during the water year. <br /> <br />Space in the top 10 feet of Lake Havasu (about <br />180,000 acre-feet) is reserved by the United States for flood <br />control and other uses, including river regulation. Normally, <br />only about the top 4 feet, or 77,000 acre-feet of space, have <br />been used for this purpose since the Alamo Reservoir on the <br />Bill Williams River has been in operation. <br /> <br />LAKE HAVASU <br /> <br />Reservoir <br /> <br />Acre-feet <br /> <br />Elevation, feet <br /> <br />Maximum Storage <br />Rated Head <br />Minimum Power <br />Surface Area, full <br />Reservoir Length, full <br /> <br />619,400 <br />619,400 <br />439,400 <br /> <br />450 <br />450 <br />440 <br />20,400 Acres <br />35 Miles <br /> <br />Powerplant <br /> <br />Number of Units <br />Total Capacity <br /> <br />4 <br />120,000 KW <br /> <br />19 <br />
