concrete-gravity structure that is flanked by embankment dams for a total length of one mile. The concrete section is long and is high from the Savannah's thalweg. The dam created the Lake Strom Thurmond which stretches up the Savannah River and up the Little River. The dam is upstream of the Savannah's mouth and combines with the Hartwell Dam (1962) and the Richard B. Russell Dam (1985) in order to form over of lakes. The dam helps provide electricity during peak-hours with seven 40-MW hydroelectricity generators. Each turbine weighs 300 tons and has a diameter. The generators are fed with water by seven , penstocks, and the dam's spillway contains 23 tainter gates that help maintaining a normal 330 ft MSL lake elevation and flooding. The dam's 700,000,000 kW·h annual production of electricity is managed by the Southeastern Power Administration See also List of dams and reservoirs in Georgia List of dams and reservoirs in South Carolina References External links USACE J.
