<br />
<br />Water Year 1990
<br />
<br />At the beginning of water year 1990, the water surface
<br />elevation of Lake Moha-.e, which is iropounded by Davis Dam,
<br />was 630.8 feel, with an active storage of approximately
<br />1,379,000 acre-feet.
<br />
<br />During the winter months, after some fluctuation, the \\'ater
<br />level was gradually raised to approximately 645 feet, with an
<br />active storage of approximately 1,760.0CXl acre-feet in the first
<br />part of February 1990. The water le",l was then lowered
<br />during the remainder of February, March, April, and May.
<br />The reser",ir de.clined to elevation 639 feet during the latter
<br />part of May 1990. During June and July, Lake Moha",
<br />gradually lowered further to an elevation of 635 feet, with an
<br />active storage of approximately 1,487,()(X) acre-feet, in the
<br />middle of July. Lake Moha", fluctuated around the elevations
<br />of 635 and 636 feet during August and then gradually rose to

<br />an elevation of 639 feet by the middle of September. The
<br />reservoir ended the water year at an etevallonof635 feet, with
<br />1,488,000 acre-feet in active storage.
<br />
<br />Lake Mohave releases were made for downstream water use
<br />requirements, including diversions by users in the vicinities of
<br />Laughlin, Nevada; Bullhead City, Arizona; and Needles,
<br />California, by The Metropolitan Water District of Southern
<br />California (MWD), the Central Arizona Project (CAP), and
<br />the users downstream from Parker Dam. During the water
<br />year, total releases of approximately 9. 140,(X)() acre-feet were
<br />made at Davis Dam, all of which passed through the turbines
<br />for power production. Of that amount approximately
<br />1,240,000 acre-feet were then pumped from Lake Havasu by
<br />MWD, and 779,000 acre-feet were pumped for the CAP.
