<br />LOWER BASIN DEPLETIONS 43
<br />
<br />Mohave Steamplant, Southern
<br />California Edison Company
<br />
<br />A portion of the allotment for Nevada has been
<br />obtained via contractual arrangements by the
<br />Southern California Edison Company for
<br />diverting up to 23,000 acre-feet annually from
<br />the Colorado River for thermal power production
<br />purposes at a site about 3 miles downstream
<br />from Davis Dam. In 1987 about 13,660 acre-feet
<br />were diverted to the Southern California Edison
<br />facility from the Colorado River below Davis
<br />Dam. Use of water until July 1,2006, by the
<br />Southern California Edison Company is in
<br />accordance with two contracts-one between the
<br />State of Nevada and the Southern California
<br />Edison Company and one between the Bureau of
<br />Reclamation and the State of Nevada.
<br />
<br />Fort Mohave Indian Reservation
<br />
<br />There are 1,939 acres of Fort Mohave Indian
<br />Reservation land located in Nevada. In 1987, no
<br />water was diverted to these lands. It has been
<br />estimated that the portion of the reservation
<br />located in Nevada will use 4,000 acre-feet by
<br />1995 and 8,000 acre-feet by 2000.
<br />
<br />laughlin and Miscellaneous
<br />Users Below Hoover Dam
<br />
<br />Uses in the Laughlin area totaled 1,758 acre-feet
<br />in 1987, but it is projected the area will use
<br />4,000 acre-feet in 1990 and 5,000 acre-feet in
<br />2000 and 2010.
<br />
<br />Arizona
<br />
<br />Imperial Wildlife Refuge
<br />
<br />The Imperial Wildlife Refuge is entitled to divert
<br />28,000 acre-feet per year or consumptively use
<br />23,000 acre-feet per year, whichever is less. In
<br />1987 the refuge diverted no water. By 1990 it is
<br />projected the Imperial Refuge will have a
<br />depletion of 13,000 acre-feet.
<br />
<br />Lake Havasu Wildlife Refuge
<br />
<br />The Lake Havasu Wildlife Refuge is entitled to
<br />divert 41,839 acre-feet or consumptively use
<br />37,339 acre-feet per year, whichever is less. In
<br />1987,38,236 acre-feet were diverted. By 1990, it
<br />is projected the Lake Havasu Refuge will have a
<br />depletion of37,OOO acre-feet.
<br />
<br />Fort Mohave Indian Reservation
<br />
<br />The Fort Mohave Indian Reservation, located
<br />below Davis Dam, is allocated water by the
<br />Supreme Court Decree to irrigate 18,974 acres
<br />ofland of which 14,916 acres are in Arizona,
<br />2,119 acres are in California, and 1,939 acres are
<br />in Nevada, with a maximum annual diversion
<br />from the Colorado River of 122,648 acre-feet.
<br />The consumptive use required for irrigation of
<br />these lands is estimated to be 4 acre-feet per
<br />acre, which would result in a mainstream
<br />depletion of about 75,900 acre-feet annually. In
<br />1987, the estimated consumptive use for that
<br />portion of the Fort Mohave Indian Reservation
<br />located in Arizona was 35,420 acre-feet.
<br />
<br />Kingman, Boulder Canyon Project
<br />
<br />A contract was signed with the city of Kingman,
<br />Arizona, for an annual diversion of 18,500 acre-
<br />feet. At the present time, the city does not
<br />divert Colorado River water, although it is
<br />currently developing plans to do so in the future.
<br />This contract water is not expected to be used
<br />until 2000. Projections for 2010 call for an
<br />annual depletion of 3,000 acre-feet.
<br />
<br />Mohave Valley Irrigation
<br />and Drainage District
<br />
<br />The Department of Interior and the Mohave
<br />Valley Irrigation and Drainage District signed a
<br />contract for an. annual diversion of 51,000 acre-
<br />feet. As a result of terms in the contract, the
<br />district lost 10,000 acre-feet of its diversion in
<br />June 1979. The 10,000 acre-feet was assigned to
<br />Bullhead City. As development occurs within
<br />this district, the trend is towards municipal
<br />uses and away from irrigation. Projections for
