46 ChapterF-Present and Future Development

Metropolitan Water District

In 1987, the Metropolitan Water District used
approximately 1,280,000 acre-feet. Future use
may be reduced as indicated in the tables when
California is limited to 4.4 million acre-feet per
year after the Central Arizona Project becomes
more fully developed.

Fort Mohave Indian Reservation

There are 2,119 acres of Fort Mohave Indian
Reservation land located in California. Using an
estimated consumptive use of 4 acre-feet per
acre, this land is entitled to approximately
9,000 acre-feet of consumptive use per year.
In 1987, its consumptive use was about
19,600 acre-feet but will be reduced when the
Central Arizona Project becomes fully
operational.

Chemehuevllndlan Reservation

The Chemehuevi Indian Reservation, located
above Parker Dam, is allocated water by the
Supreme Court Decree to irrigate 1,900 acres of
land in California, with a maximum annual
diversion from the mainstream of the Colorado
River of 11,340 acre-feet. The consumptive use
required for irrigation of these lands is
estimated to be 4 acre-feet per acre, which
would result in a mainstream depletion of about
7,600 acre-feet annually. The lands that are
irrigable are above the river and not feasible for
farming at this time. The reservation is
expected to develop 7,600 acre-feet of
consumptive use for municipal and industrial
and/or irrigation purposes by 2000.

Colorado River Indian Reservation

The Colorado River Indian Reservation is
located along the Colorado River, just below
Parker Dam, with most of the land in Arizona

and the remainder in California. The Supreme
Court Decree allocated 717,148 acre-feet of
diversions to the Colorado River Indian
Reservation for irrigation of 107,588 acres of
land. There are 8,213 acres ofland in California
that are partially developed and that will
eventually consume about 33,000 acre-feet.

Palo Verde Irrigation District

The Palo Verde Irrigation District has the first
priority in California for Colorado River water
under the Seven Party Agreement to irrigate a
total of 104,500 acres with an estimated
consumptive use of 423,000 acre-feet per year.

Yuma ProJect, Reservation Division

California lands within the Yuma Project have
the second priority according to the Seven Party
Agreement. In the Indian Unit, Arizona vs.
California reserves water for 7,743 acres of land
that would require an approximate consumptive
use of31,OOO acre-feet. The Bard Unit has
about 7,000 acres ofland that have an approx-
imate consumptive use of 24,000 acre-feet.

Imperial Irrigation District

For this report, the Imperial pistrict and the
Coachella Valley Water District consume all
remaining water within priorities one, two, and
three according to the Seven Party Agreement.
The total apportioned to these priorities is
3,850,000 acre-feet per year. In 1987, the
Imperial Irrigation District diverted about
2,270,000 acre-feet. Its projected diversions will
reach 2,963,000 acre-feet in 1990.

Coachella Valley Water District

In 1987 the District diverted about
270,000 acre-feet.
