Shasta Dam, Concrete arch-gravity dam in Shasta County, California.
Shasta Dam is a concrete arch-gravity dam that spans the Sacramento River and creates Shasta Lake, California's largest reservoir. The structure operates five turbines that manage water storage and flood control for the state's northern agricultural regions.
Construction began in 1938 under Chief Engineer Frank Crowe as part of the Central Valley Project and finished in 1945 during World War II. The project was completed ahead of schedule and became a significant piece of the state's infrastructure during that era.
The construction flooded the pioneer settlement of Kennett and sacred sites of the Winnemem Wintu people beneath the lake's surface. This loss remains part of the local communities' connection to this place today.
The dam is open to visitors during daylight hours and offers viewpoints to see the structure and the lake from above. Comfortable shoes are recommended since walking around the site involves stairs and longer paths.
The structure contains millions of cubic meters of material and ranks among the tallest dams in the nation. This massive material volume was essential to contain the enormous water volume over many decades.
