Abstract:

Hartwell Lake, located between Georgia and South Carolina along the Savannah River basin, was the site of an extensive water quality study during 1991. Temporal and longitudinal trends were identified through monthly in situ monitoring and bi-annual chemical analyses. The onset of thermal stratification began on Hartwell Lake during late March. By May, extensive stratification was present from headwaters to the forebay. Anoxic conditions were first observed in the middle reaches of the Seneca and Tugaloo River embayments during the July sampling. The greatest concentrations of chemical constituents within the tributary embayments were recorded during the mid- to late summer period. Progression of the anoxic zone from the mid-embayments towards Hartwell Dam was observed during the July through October period. Stratification and accompanying anoxia in the upstream regions were diminished by early October due to seasonal cooling and mixing processes. In the deepwater -car-dam areas, anoxic conditions persisted until November. Dissolved oxygen, Savannah River, Lake Hartwell, Water Quality. Limnology,
