The Army Corps of Engineers considers it to be the greatest flood hazard west of the Mississippi River. It produced devastating floods in 1862, 1938, and 1969. As a result of the 1938 flood, the Prado Dam was built near Corona in 1941. Officials in Orange County felt further protection was needed. The Seven Oaks Dam was completed in 1999, located a few miles north of Redlands.
