Folsom Dam releases impressive waterfall
The five main gates of Folsom Dam poured water downriver on the American over the weekend.
The dam provides drainage for about 1,875 square miles. The California Department of Water Resources reported the lake elevation on March 26 was 433.54 ft. Lake elevation has been held to between 428 and 441 feet for the past month.
Water operations cannot flush too much water or the levees downstream may be damaged. Releases that are too small can compromise the dam’s ability to control water from spring snowmelt.
A spillway being constructed next to the dam will help with flood control. It is scheduled to be completed in 2015.
