PACIFIC SOUTHWEST WATER PLAN (Bureau of Indian Affairs' Statement) THE PACIFIC SOUTHWEST Natural Resources Land There are five Indian Reservations along the main stream of the Lower Colorado River, eighteen reservations on tributaries, six in the inland basin of California, and several in the southern California coastal area. In succession down the river, the mainstream reservations are: Fort Mohave in Arizona, California, and Nevada; Chemehuevi in California; Colorado River in Arizona and California; Yuma in California; and Cocopah in Arizona. The reservations on tributaries and in California are listed later in this report, with estimates of water requirements. The principal resources of most of the reservations are their irrigable lands and appurtenant water rights. The irrigable acres and water rights for the mainstream reservations, as provided under the Supreme Court decision in Arizona vs. California, are shown in the following tabulation: Arizona Irrigable Area (Acres) California Nevada TOTAL Fort Mohave 14,916 2,119 1,939 18,974 Chemeheuvi 0 1,900 0 1,900 Colorado River 99,375 8,213 0 107,588 Yuma 1 7,743 0 7,743 Cocopah 431 0 0 431 Totals 114,722 19,975 1,939 136,636 1 Indian Homesteads included with non-Indian lands of Yuma Project (USBR). 2Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,411,776 byte
