Folsom Dam Safety and Flood Damage Reduction - Folsom Dam Raise

Folsom Dam Safety and Flood Damage Reduction - Folsom Dam Raise

As part of the Folsom Dam Raise Project, the Central Valley Flood Protection Board, the Sacramento Area Flood Control Agency, US Army Corps of Engineers, and the US Bureau of Reclamation propose to modify the spillway gates, raise; the Dam, wing dams, and dikes by 3.5 ft. Structural modifications associated with the Folsom Dam Raise project are proposed to provide increased flood damage protection by increasing the flood storage capacity and/or pool release mechanisms at the Folsom Facility. These modifications add flood damage reduction benefits, while still safely allowing passage of the Probable Max Flood, by creating additional surcharge space (temporary water storage space utilized during rare flooding events) within the reservoir.
