The Saluda 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
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. tall roller-compacted concrete dam
was completed at the toe of the original dam in order to mitigate an earthquake-caused dam failure.
The SC 6
highway crosses over the dam and is used as a fast connection between the towns of Lexington, SC
and Irmo, SC
. The yearly football game between rival Lexington High School
and Irmo High School
is often called 'The Battle of the Dam'.
The original Saluda Dam is a 7,800 ft. long, 213-foot-high earthen-embankment dam. The dam contains a 2,900 ft. long emergency spillway
controlled by six steel tainter gates
. The back-up dam located at the original dam's toe and is a 2,300 ft. long, 213-foot-high roller-compacted concrete
dam. Rock-fill embankment sections also exist on the south and north ends of the back up dam, making a total length of 5,700 ft.
