Appraisal Report Central Arizona Project

Document: "Appraisal Report Central Arizona Project-Chapter IV", January 1962, page 39CHAPTER IV - PLAN OF DEVELOPMENT General To make Colorado River water available for the Central Arizona Project area, the aqueduct system starting from Havasu Reservoir on the Colorado River at Parker Dam would raise and deliver the water directly into the Central Service Zone. The relation of facilities of the Central Arizona Project to existing facilities is shown on the General Location Map (plate 1). By these facilities, the imported waters and the water resources of the Gila River Basin would be coordinated. Through hydrologic coordination and exchanges, vital and essential basinwide water uses would be possible for continuing economic health. The project is designed to make use of powerheads for the generation of electric energy for commercial and irrigation uses. Additional purposes would include flood control, recreation, fish and wildlife conservation, sediment retention and salinity control. Project Facilities The keystone facility for the Central Arizona Project is the Bridge Canyon Dam, Reservoir and Powerplant which would provide the energy for pumping to the Central Service Zone. The imported water would make exchanges possible for the Upper Tributaries Zone. Present conditions within the Central Service Zone have dictated the modifications of the facilities presented in the original report. Costs have been revised with additional data to reflect current conditions. Modifications of the aqueduct system are required to meet the rapid and extensive urbanization and agricultural growth. The primary facilities for the Central Service Zone, as shown on plate 2, are: 39Epson Perfection 4870 Photo, 400 dpi, 8 bit, 943,198 byte
