Upper Savannah

Watershed Hydrology

The Upper Savannah watershed (HUC 03060103) covers approximately 3,512 square miles and includes parts of Georgia and South Carolina. The hydrology of the area is dominated by the Savannah River, which flows through the watershed and feeds Lake Hartwell and Lake Russell, two large reservoirs in the region. The area experiences snowfall primarily in January and February, with average snowpack depths ranging from 0 to 2 inches. Surface water in the watershed is influenced by agricultural activities, with nutrients such as nitrogen and phosphorus being common constituents. Interesting climatic facts include the area's high humidity levels, which can make hot summer temperatures feel even more oppressive. There has been a trend of increasing temperatures and decreasing precipitation in the region over the past few decades, which could have significant impacts on the hydrology and ecology of the watershed.
