Located at 17801 Lake Perris Drive in Perris, California, this artificial lake was completed in 1973 and serves as the southern terminus of the California State Water Project. The Ya’i Heki’ Regional Indian Museum inside the park is worth a visit, offering fascinating context about the California State Water Project and the native peoples of the southern California desert region.
