J. Strom Thurmond Dam
Constructed between 1946-1954, Thurmond Dam is the first hydropower project to be built on the Savannah River. Behind it lies one of the largest Corps of Engineer lakes east of the Mississippi.
The Thurmond Dam powerhouse contains seven power units, each capable of generating 40,000 kilowatts. Its average annual energy output is 920-million kilowatt hours.
Since its completion, Thurmond Dam has prevented millions of dollars in flood damage to down stream sites, and had produced power revenues sufficient to repay its original construction cost in less than 25 years.
Marker can be reached from U.S. 221.
