Shasta Dam is a curved gravity concrete dam (National ID No. CA10186) on the Sacramento River above Redding, California near Shasta Lake City built between 1938 and 1945. Like another curved gravity dam (Hoover Dam), it was a continuous pour concrete project, and in its day, ranked as one of the great civil engineering feats of the world.
The dam is 602 ft (183 m) high and 3,460 ft (1,055 m) long, with a base width or thickness of 543 ft (165.5 m).
The reservoir created behind Shasta Dam is known as Shasta Lake and is a popular recreational boating area.
