<br />Parker Dam, Lake Havasu <br /> <br />RESERVOIP <br /> <br />(ACRE. <br />FEET) <br />619.400 <br />619.400 <br />439.400 <br />20.4QQACRES <br />35MILES <br /> <br />eleVATION <br />(FEEn <br /><5'10 <br />450.0 <br />.$400 <br /> <br />At the beginning of water year 1976, the water <br />level 01 Lake Havasu was at elevation 447 feet, <br />with an active storage of 553,000 acre-feet. The <br />reservoir was drawn down to about elevation 446 <br />feet with an active storage of about 537,000 acrc- <br />feet in November and remained near that level <br />through mid-March to provide flood control space <br />for runoff from the drainage area between Davis <br />and Parker Dams, The water level was then raised <br />to about elevation 450 feet by mid-May, During <br />mid-May through June, the reservoir water level <br />was maintained near maximum, with an active <br />storage of about 605,000 acre-feet, and then was <br />drawn down to 448 feet with an active storage of <br />580,000 acre-feet by the end of the water year. <br /> <br />During the water year, 6,855,000 acre-feet Were <br />released at Parker Dam, all of which passed <br />through the turbines for power production. <br /> <br />Joint-use space in the top 10 feel of Lake Havasu <br />(about 180,000 acre-feet) is reserved by the United <br />States for control of floods and other uses, includ- <br />ing river regulation. Normally, only about the top <br />4 feet, or 77,000 acre-feet of space, are used for <br />this purpose now that Alamo Reservoir on the Bill <br />Williams River is in operation.
