South Holston Dam

South Holston lake can be found in Sullivan County Tennessee and Washington County Virginia reaching cities such as Bristol, Tennessee/Virginia and Abingdon Virginia.

According to www.tva.com, construction of South Holston’s dam began in 1942 and was completed in 1950. Construction was halted due to World War II but resumed in 1947.

South Holston Dam was built in order to produce power, reduce flood damage and to increase the flow of water during dry periods.

The earth-and-rockfill dam stretches 1,600 feet across the South Fork Holston River and stands at 285 feet high.

A weir, which is a low-lying dam built in order to regulate a river’s flow, was constructed in 1991 below South Holston Dam.

The weir helps add oxygen to the lake’s water when the dam isn’t generating, promoting a healthy habitat for aquatic life and vegetation.

According to www.tnfish.org, fish such as catfish, trout, smallmouth and largemouth bass can be found in the lake.
