Prado Dam
From Wikipedia, the free encyclopedia
The Prado Dam is a rock-fill dam on the Santa Ana River near Corona, California in Riverside County. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 miles upstream from the ocean. The area upstream from the dam contains 2,255 square miles of the watershed's 2,450 square miles. The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. As of 2005 work to increase the downstream channel's capacity from 5,000 to 30,000 cubic feet per second is ongoing. Prado Dam also provides water storage for groundwater recharge operations.
On January 14, 2005, water began seeping through an earthen extension. Authorities released water in order to relieve pressure and sent a flood warning to areas downriver of the dam.
