The Painted Rock Dam was constructed during a 3-year period from 1957–1960 by the United States Army Corps of Engineers to help control seasonal floods on the lower reaches of the Gila River. The river had no significant impediments between the Colorado River and the Coolidge Dam hundreds of miles upstream.

In the late 1950s, the problem became more and more pronounced, until in 1959 the Arizona State Legislature formed the Maricopa County Flood Control District (MCFCD). The MCFCD became the lead player in developing a comprehensive flood plan for the entire county.
