Rancho Seco Recreational Park is a recreational area located in the California Central Valley near the Rancho Seco Nuclear Generating Station in Herald, California. It is open to the public for camping, fishing, hiking and water activities. Boats are restricted to outboard electric motors which improves the lake's use as a swimming hole. The lake is fed by the Folsom South Canal.
