The Central Arizona Project was authorized on September 30, 1968, as part of the Colorado River Basin Project Act, Public Law 90-537 (82 Stat. 885). While "Title V– Upper Colorado River Basin: Authorization and Reimbursements," provided for construction of Animas-La Plata, Dolores, Dallas Creek, West Divide, San Miguel, and Central Utah (Unitah Unit) Projects, CRBP was largely legislation that actualized the long pursued dream of diverting Colorado River water to central Arizona. In this photo, President Lyndon Johnson signs the legislation, handing a pen to Senator Carl T. Hayden, who had been influential in getting the legislation passed.
