<br />LAKE MEAD
<br />(COLORADO RIVER)
<br />
<br />Water Year 1994
<br />
<br />At the beginning of water year 1994, Lake Mead, impounded
<br />by Hoover Dam, had a water surface elevation of 362.1
<br />meters (1188.0 feet) and an active storage of 26,185 million
<br />cubic meters (21,228,000 acre-feet). During the winter
<br />months, the water level continued to gradually rise and by
<br />the end of December the water surface elevation was 362.2
<br />meters (1188.2 feet) with an active storage of 26,303 million
<br />cubic meters (21,324,000 acre-feet). Lake Mead continued
<br />to rise through the winter months' and by the end of
<br />February 1994, the water surface elevation was 363.0 meters
<br />(1190.97 feet) with an active capacity of 26,683 million cubic
<br />meters (21,632,000 acre-feet). Then Lake Mead elevation
<br />gradually declined to 359.1 meters (1178.24 feet) by the end
<br />of August 1994. Lake Mead elevation rose to elevation 359.2
<br />meters (1178.4 feet) by the end of the water year with a
<br />corresponding active storage of 24,583 million cubic meters
<br />(19,930,000 acre-feet).

<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 1994 was approximately
<br />11,607 million cubic meters (9,410,000 acre-feet). AU of the
<br />amount passed through the turbines for power production.
<br />In addition 392 million cubic meters (318,000 acre-feet) were
<br />diverted from Lake Mead by the Project. At the end of the
<br />water year, Lake Mead had a water surface elevation of
<br />359.2 meters (1178.4 feet) and an active of 24,583 million
<br />cubic meters (19,930,000 acre-feet) which reflects a decrease
<br />in storage during the water year of 1,787 million cubic
<br />meters (1,449,000 acre-feet). On September 30, 1994, the
<br />active storage of Lake Mead was 2,661 million cubic meters
<br />(2,157,000 acre-feet) greater than the active storage in Lake
<br />PoweU.
