STS062-083-065 Clark Hill Lake, Georgia and South Carolina, U.S.A. March 1994 The Savannah River flows southeasterly through the longer northwest arm of Clark Hill Lake, which receives muddy sediment plumes from numerous tributary streams. Below Strom Thurmond Dam at the lake's southeast end, the vegetated floodplain of the Savannah River widens, and the meandering main channel of the river passes north and eventually east of Augusta. Some street patterns of northern Augusta are discernible (upper left corner). Linear, light Interstate Highway 20 enters the western suburbs of Augusta. The general terrain consists of rolling, wooded areas and lighter agricultural fields.
