Appraisal Report Central Arizona Project

Document: "Appraisal Report Central Arizona Project- Synopsis", January 1962, page 14These concepts for the future have been included in this appraisal report to emphasize: 1. That the Central Arizona Project plan presented herein is only a part of a more comprehensive basin-wide plan of water conservation and development required to sustain the existing economy and permit future growth of the entire Lower Colorado River Basin; and 2. That financial assistance from existing and potential hydroelectric power developments along the Lower Colorado River will be required to accomplish such long-range objectives as (a) the lining of the All-American and Coachella Canals; (b) the salvage of water along the Colorado and Gila Rivers through channel rectification and clearing of phreatophytes; (c) the importation of additional needed quantities of water, such as a United Western Program; and (d) the development of other potential projects in the Lower Colorado River Basin. Summary and Conclusions The hydrologic, engineering and economic studies made during this appraisal of the original Central Arizona Project report have forcibly brought to attention the following conditions, facts, and conclusions: 1. Since the original report on the Central Arizona Project was prepared, the population of the project area has approximately doubled and now totals over 1 million. Projections by responsible authorities indicate that this rate of population growth may be expected to continue. 2. The metropolitan areas of Phoenix and Tucson are now in need of a dependable supplemental supply of water for municipal and industrial uses and this need will continue to increase in the future. 14Epson Perfection 4870 Photo, 400 dpi, 8 bit, 1,011,382 byte
