Excavation of Folsom Dam’s new auxiliary spillway continues in Folsom, Calif., Dec. 29, 2011. The spillway will allow Folsom Dam to release water sooner and more safely. The project is part of the Folsom Dam Joint Federal Project, a joint effort of the U.S. Army Corps of Engineers Sacramento District, the U.S. Bureau of Reclamation, the Central Valley Flood Protection Board and the Sacramento Area Flood Control Agency to improve the safety of the dam and reduce flood risk for the greater Sacramento area.
