Mauldin, G V

Like most deep water bodies, Clarks Hill Lake undergoes thermal stratification during the summer and early fall resulting in a relatively cold, oxygen depleted bottom layer of water termed the hypolimnion. The turbine intakes are located far below the surface in this hypolimnion; therefore, it is this lower layer of water that is released from the dam year-round, and during the summer, the waters released have relatively low dissolved oxygen (D.O.) concentrations. Georgia and South Carolina state water quality standards for the Savannah River below Clarks Hill Dam require an average daily D.O. concentration of 5 milligrams per liter (mg/l) with a minimum of 4 mg/1. Various methods have been investigated to improve the D.O. concentrations in the releases from Clarks Hill Dam. One method is to vent air into the draft tube below the hydropower turbine.
