<br />At the beginning of water year 1973 the level
<br />of Lake Havasu was 447 feet with an active sto-
<br />rage of 560,000 acre-feet. The level was drawn
<br />down to about 446 feet with an active storage of
<br />about 537,000 acre-feet on November I and re-
<br />mained near that level through March 9 to pro-
<br />vide flood control space for runoff from the
<br />drainage area between Davis and Parker Dams.
<br />The level was then raised to near full condition
<br />by mid-May. During the May 15 through June 30
<br />period the level was maintained near maximum
<br />with an active storage of about 605,000 acre-
<br />feet and then was drawn down ta 447 feet with
<br />an active storage of 559,000 acre-feet by the
<br />end of the water year. There were 6,651,000
<br />acre-feet released at Parker Dam during the
<br />water year, all of which passed through the
<br />turbi nes for power producti on.
<br />Joint use space in the top 10 feet of Lake
<br />Havasu (about 180,000 acre-feet) is reserved by
<br />the United States for control of floods and other
<br />uses including river regulation. Now that Alamo
<br />Reservoir on the Bill Williams river is in opera-
<br />tion, only about the top 4 feet or about 77,000
<br />acre-feet of space is nonnally used for this
<br />purpose. (Chart 9)
