Lake Cahuilla was built in 1969 by the Portland Cement Association for the Coachella Valley Water District. At the time it was the largest soil cement lined reservoir in the United States.

The lake has a surface area of 135 acres and a storage capacity of about 1,500-acre feet of irrigation water. Lake Cahuilla is the terminus of the 123-mile Coachella Branch of the All-American Canal near Jefferson Street in La Quinta.

Today, it is part of Lake Cahuilla Veterans Regional Park operated by the Riverside County Regional Park and Open-Space District.
