Slab Creek Dam, Concrete arch dam in El Dorado County, California, US
Slab Creek Dam is a concrete arch dam spanning the Upper South Fork American River high in the Sierra Nevada mountains. The structure holds back water that feeds into a connected series of hydroelectric facilities throughout the region.
The Sacramento Municipal Utility District built this dam in 1967 as part of a major hydroelectric project for the region. The facility became one of several dams constructed to meet growing energy demands in the area.
The dam forms part of an 11-dam system that produces renewable energy, supplying 20 percent of Sacramento's annual electricity requirements.
The dam site is remote and not developed for public visitation or access. Visitors interested in the facility should plan accordingly as nearby towns offer the closest services and amenities.
The dam's water release system underwent modifications in 2017, requiring complete river diversion and transforming the structure into a temporary 250-foot waterfall.
