<br />OJ2233 <br /> <br />PACIFIC SOUTHWEST WATER PLAN <br /> <br />APPENDIX <br /> <br />Bureau of Reclamation <br /> <br />. <br /> <br />In the Colorado River Basin, drainage boundaries have not been <br />recognized as a restricting barrier to water resource development <br />and use for many years. Waters of the Colorado River drainage area <br />either are being, or will shortly be, diverted from the Colorado <br />Basin to be mingled with the waters of the Bonneville Basin and the <br />Platte, Arkansas, Rio Grande, Los Angeles, Owens, Santa Ana, San <br />Diego, Sacramento, and San Joaquin Rivers. As water n-e-eds become <br />more critical in the West, river basin boundaries will be~ome even <br />less rigid in water and land resource development. <br /> <br />All of the surface and underground water resources of the <br />Pacific Southwest area have been considered in development of the <br />Pacific Southwest Water Plan. In addition, some of the' surplus <br />waters from the north coastal basins in California are considered <br />for importation to the area. Saline water conversion plants and <br />reuse of return flow and sewage effluent are also involved in the <br />plan of development. <br /> <br />The existing and proposed developments in the Colorado River <br />Basin and in the Central Valley and north coastal basins of <br />California are influenced by, and influence the formulation of, <br />any plan which proposed additional uses of the waters in these <br />systems. <br /> <br />. <br /> <br />To attempt to document the wealth of information, plans, and <br />alternative plans for water resource development that have been <br />considered to accomplish various purposes in the Pacific Southwest <br />would be beyond the scope of this appendix. A partial list of com- <br />pleted, or soon to be completed, Bureau of Reclamation reports <br />which are pertinent to the problem is therefore provided and the <br />several alternative plans for sea-water desalting and California <br />supplemental diversion routes which were presented briefly in the <br />report are discussed in further detail. <br /> <br />Partial List of Pertinent Bureau of Reclamation Reports <br /> <br />Buttes Dam and Reservoir, Middle Gila River Project, Arizona, <br />January 1961 <br />Central Arizona Project, Arizona-New Mexico, December 1947 <br />Central Arizona Project, Supplemental Report, Arizona-New Mexico <br />Dixie Project, Utah, October 1961 <br />Southern Nevada Water Supply Project, Nevada, June 1963 <br />East Side Division, Central Valley Project, California <br /> <br />1 <br /> <br />
