<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 /> <br />ACTUAL RELEASES 111M <br /> <br />IllLU01f e&.c .... <br />1100 <br /> <br />__ ACIINDT <br />.... <br /> <br /> /' ......, <br /> / '\. <br />........ / ....... - \. <br /> <br />1000 <br /> <br />1111 <br /> <br />'zoo <br /> <br />In <br /> <br />lOG <br /> <br />.21 <br /> <br />100 <br /> <br />... <br /> <br />... <br /> <br />z., <br /> <br />. . <br />~F"~~;-.f'~'I"" <br /> <br /> <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. <br /> <br />lAKE MEAD <br /> <br />Reservoir <br /> <br />Storage Capacity <br />Normal Pool Elevation <br />Minimum Power Pool <br />Surface Area, full <br />Reservoir Length, full <br /> <br />33,769 million cubic meten: ('r/;J'n,fXXJ acre-reet) <br />374.6 meters (1229,0 reel) <br />330,1 meters (1083,0 reel) <br />65,843 hectaIu (162.700 ocreo) <br />185 kilometers (115 mila) <br /> <br />Powemlant <br /> <br />Number of Unil& <br />Total Capacily <br /> <br />17 <br />1,964.soo KW <br /> <br />l5 <br />
