Most people never have the opportunity to see or visit a dam in their lifetime. But a new program aims to change that.

UCR Friends of the Santa Ana River (RíRiver) will host a tour of Prado Dam with experts from the Army Corps of Engineers on Oct. 25 from 12:30 p.m. to 2 p.m. The tour is limited to 30 people.

Reservations are required and may be made by contacting Steve Mitchell, distinguished librarian, at

Prado Dam is an earth-fill dam across the Santa Ana River in the Chino Hills, near Corona, with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon to control flooding along the river.
Construction was authorized in 1936 and completed in 1941.
