<br />At the beginning of water year 1974, the level
<br />of Lake Havasu was 447 feet with an active storage
<br />of 559,000 acre-feet. The level was drawn down
<br />to about 445 feet with an active storage of about
<br />525,000 acre-feet on January 25 and remained
<br />near that level through March 13 to provide flood
<br />control space for runoff from the drainage area
<br />between Davis and Parker Dams. The level was
<br />then raised to near full condition by mid-May.
<br />During the May 15 through June 30 period, the
<br />level was maintained near maximum with an active
<br />storage of about 605,000 acre-feet and then was
<br />drawn down to 447 feet with an active storage
<br />of 561, I 00 acre-feet by the end of the water year.
<br />There were 7,282,800 acre-feet released at Parker
<br />Dam during the water year, all of which passed
<br />through the turbines for power production.

<br />Joint use space in the top 10 feet of Lake
<br />Havasu (about 180,000 acre-feet) is reserved by the
<br />United States for control of floods and other uses
<br />including river regulation. Now that Alamo
<br />Reservoir on the Bill Williams River is in
<br />operation, only about the top 4 feet or about
<br />77,000 acre-feet of space is normally used for this
<br />purpose. (Chart 9)
