<br />LAKE MEAD
<br />(COLORADO RIVER)
<br />
<br />Water Year 1995
<br />
<br />At the beginning of water year 1995, Lake Mead, impounded
<br />by Hoover Dam, had a water surface elevation of 359.1
<br />meters (1177.8 feet) and an active storage of 24,487 million
<br />cubic meters (19,852,000 acre-feet). During the water year,
<br />Lake Mead reached its minimum elevation of 358.4 meters
<br />(1175.69 feet) in November. After that, Lake Mead
<br />continued to gradually rise, reaching its maximum for the
<br />year in September with an elevation of 361.1 meters (1184.3
<br />feet) and corresponding active storage of 25,551 million
<br />cubic meters (20,714,000 acre-feet) to fInish out the water
<br />year. This reflects an increase in storage of 1,063 million
<br />cubic meters (862,000 acre-feet).
<br />
<br />Lake Mead and Lake Powell did not equalize by September
<br />30. The active storage of Lake Mead on September 30,
<br />1995, was 1,970 million cubic meters (1,597,tXXJ acre-feet)
<br />less than the active storage in Lake Powell. Due to the
<br />above normal April through July runoff, releases out of Lake
<br />Powell had to be increased during the summer months
<br />resulting in Lake Mead and Lake Powell equalization taking
<br />place during December.

<br />During the water year, releases were made to meet
<br />downstream water use requirements in the United States and
<br />Mexico, programmed levels of Lake Mohave and Havasu,
<br />and net transit losses which include river and reservoir
<br />evaporation, uses by phreatophytes, changes in bank storage,
<br />unmeasured inflows, and diversions to the Las Vegas,
<br />Nevada area via the Robert B. GriffIth Water Project
<br />(Project). The total release from Lake Mead through
<br />Hoover Dam during the water year 1995 was approximately
<br />10,798 million cubic meters (8,754,000 acre-feet). All of the
<br />amount passed through the turbines for power production.
<br />In addition, 406 million cubic meters (329,000 acre-feet)
<br />were diverted from Lake Mead by the Project.
