The Metropolitan Water District of Southern California was created in 1928, as increasing residential and commercial development in the region began to overtax the existing water supply. Its purpose was the develop a domestic water supply via the Colorado river. The reports here discuss the engineering studies conducted and data collected to determine possible aqueduct routes, describe several different routes that were considered, and review the related legislation and legal and political obstacles. The Final Report concludes that "the best, the safest, and the most economical location for the acqueduct from the Colorado River is that known as the Parker Route" [which diverted water from the Colorado 150 miles below the Hoover Dam.] This recommendation was accepted, and in January 1933 work began on the Colorado River Aqueduct, which is now one of the primary sources of drinking water for Southern California.
