The Saluda Dam or Saluda River Dam, officially the Dreher Shoals Dam, commonly referred to as the Lake Murray Dam, is an earthen embankment dam located approximately 10 miles (15 km) west of Columbia, South Carolina on the Saluda River. Construction on the dam began in 1927 and was completed in 1930. The purpose of the dam is flood control, hydroelectricity, recreation and water supply. At the time of its completion, the Saluda Dam was the world's largest earthen dam, creating the world's largest man-made lake, Lake Murray. In 2005, construction on a 213 ft (65 m). tall roller-compacted concrete (RCC) dam was completed at the toe of the original dam in order to mitigate an earthquake-caused dam failure.
