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 1993, it diverted about 18,700 acre-feet which will be
reduced when California is limited in its use of Colorado River water. The estimated
consumptive use for 1993 was 8,300 acre-feet.

Chemehuevi Indian 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
mainstem 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 classified
as irrigable are not feasible for farming at this time. The reservation is expected to
develop 1,000 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. In 1993, the Colorado River Indian Reservation diverted
about 7,800 acre-feet to California.

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. In 1993, an estimated 334,500 acre-feet were
consumptively used.

Yuma Project, Reservation Division-California lands within the Yuma Project
have the second priority under the Seven Party Agreement. In the Indian Unit,
Arizona v. California reserves water for 7,743 acres ofland. The Bard Unit has about
6,294 acres of land. The estimated consumptive use of the two units in 1993 was
58,000 acre-feet.

Imperial Irrigation District-The Imperial Irrigation District and the Coachella
Valley Water District have rights to the remaining water within the first three
priorities under the Seven Party Agreement. The total apportioned to these priorities
is 3,850,000 acre-feet per year. Under the Imperial Irrigation DistrictlMetropolitan
Water District Conservation Agreement, the first three priorities will be limited to
3,740,000 acre-feet by 1995, with the 106,000 acre-feet made available to the
Metropolitan Water District. In 1993, the Imperial Irrigation District consumptively
used about 2,772,150 acre-feet.

Coachella Valley Water District-In 1993, the Coachella Valley Water District
consumptively used about 319,000 acre-feet of water.
