Work begins on new Folsom Dam spillway

SACRAMENTO, Calif. 6/1/12 (PennWell) -- Construction has begun on a new flood control spillway at California's Folsom Dam as crews have begun pouring concrete for the site's new control structure.

The 146-foot-high structure, which is being constructed adjacent to the existing Folsom Dam, will include six steel gates positioned 50 feet lower than the spillway gates on the current dam.

This will allow for an earlier release of floodwaters, says the U.S. Army Corps of Engineers, which will almost double Folsom Dam's flood safety rating when completed in 2017. Need for the new structure was identified in the U.S. Bureau of Reclamation's Safety of Dams program and is being executed alongside rehabilitation of the 198.72-MW Folsom power plant.

The US$1 billion project is a joint collaboration between the Corps, Reclamation, state of California and Sacramento Area Flood Control Agency.
