The dam is earthen and rockfill, built solely to divert water into irrigation canals serving the Palo Verde Irrigation District. It measures 1,850 feet long at its crest, which is at an elevation of 283.5 feet, and stands 46 feet high above the riverbed, containing approximately 175,000 cubic yards of material. Construction of the dam, which began in 1956 and ended in 1958, was authorized by the U.S. Bureau of Reclamation. The dam was constructed to raise the water level of the river because the upstream Hoover and Davis Dams blocked sediment, causing significant degradation of the riverbed that hampered water diversion.
