Reports, correspondence and publications primarily selected from the Senator Carl T. Hayden Papers regarding water allocations, engineering, politics, and litigation associated with the Central Arizona Project (CAP) and the Colorado River. A Congressman and then U.S. Senator from Arizona serving from 1912-1970, Hayden influenced natural resource development, water reclamation, and land-use management, culminating in 1968 with approval of funding for the CAP to transport Colorado River water to Phoenix and Tucson.

The Colorado River Central Arizona Project Collection is part of the Western Waters Digital Library (WWDL) which contains government reports, classic water literature, legal transcripts, water project records, personal papers, photographic collections, and video materials about the Columbia, Colorado, Platte, and Rio Grande river basins.
