Lake Havasu Wildlife Refuge-The Lake Havasu Wildlife Refuge is entitled to divert
4l,839 acre-feet or consumptively use 37,339 acre-feet per year, whichever is less.

Fort Mohave Indian Reservation-The Fort Mohave Indian Reservation, located below Davis
Dam, is allocated water by the Supreme Court Decree to irrigate 20,076 acres of land of which
16,018 acres are in Arizona; 2,ll9 acres are in California; and 1,939 acres are in Nevada. For the
land in Arizona, the reservation is allocated the lesser o~ an annual diversion of l03,535 acre-feet
or the quantity of water necessary to satisfy the consumptive use for 16,018 acres. The
consumptive use required for irrigation of these lands is estimated to be 4 acre-feet per acre
(64,072 acre-feet).

City of Kingman-A contract was signed with the city of Kingman, Arizona, for an annual
diversion of 18,500 acre-feet. At the present time, the city does not divert Colorado River water,
and its entitlement has been transferred to other users in Arizona.

Mohave Valley Irrigation and Drainage District-The Department of the Interior and the
Mohave Valley Irrigation and Drainage District signed a contract for an annual diversion of
51,000 acre-feet. As a result of terms in the contract, the district lost 10,000 acre-feet of its
diversion in June 1979. The 10,000 acre-feet was assigned to Bullhead City. As development
occurs within this district, the trend is toward municipal uses and away from irrigation.

Bullhead City and Other Municipal and Industrial-A contract was signed with Bullhead City
for an annual diversion of 8,200 acre-feet per year.

Cibola Valley Irrigation and Drainage District, Parker, and Others-A contract was signed
with Cibola Valley Irrigation and Drainage District for an annual diversion of 22,560 acre-feet.

Lake Havasu Irrigation and Drainage District-Contracts exist with Lake Havasu Irrigation and
Drainage District for an annual diversion of up to 14,500 acre~feet.

Central Arizona Project-The Colorado River .Basin Project Act authorizes the Central Arizona
Project to furnish irrigation and municipal water supplies to the water-deficient areas of Arizona
and western New Mexico through direct diversion or exchange of water. The project started
delivering water to Tucson in 1992. This project provides water to Indian lands and a replacement
water supply to non-Indian lands now being irrigated. Water made available to non-Indian lands
can be used only on lands having a recent irrigation history. The Central Arizona Project must
withstand shortages up to its full allocation if there is insufficient mainstream water to satisfy an
annual consumptive use of 7.5 maf apportioned under the Supreme Court Decree of March 1964
to the States of Nevada, Arizona, and California. When shortages occur, diversions to the Central
Arizona Project will be limited to ensure senior priority right holders of their entitled diversions
from the Colorado River mainstream water. A maximum of 2.17 million acre-feet of Colorado
River water could be diverted with a canal capacity of 3,000 cubic feet per second.

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 the lessor of 717,148 acre-feet of diversions to
the Colorado River Indian Reservation or the quantity necessary to supply the consumptive use for
