It was impounded in the late 1920s to provide hydroelectric power to the state of South Carolina. Lake Murray is fed by the Saluda River, which flows from upstate South Carolina near the North Carolina state line. The Saluda Dam (officially the "Dreher Shoals Dam") was an engineering feat at the time of its construction. The dam, using the native red clay soil and bedrock, was the largest earthen dam in the world when it was completed in 1930. Lake Murray itself is named after the project's chief engineer, William S. Murray. The Saluda Dam is approximately long and high. Lake Murray is long, and wide at its widest point. At the time when the lake was finished, it was the world's largest man-made reservoir.
