Lake Spaulding Dam (National ID # CA00358) is a dam in Nevada County, California. Owned and operated by Pacific Gas & Electric for hydroelectric power generation, the 275-foot (84 m)-high dam was designed by John R. Freeman and completed in 1913 . It impounds the South Fork of the Yuba River, which originates near Donner Pass. At the time of construction it was the highest dam in California, and one of ten PG&E hydroelectric facilities. A temporary camp called Camp Spaulding, California was established to house workers on the dam during its construction.
