Bathymetry of Stevens Creek and Neal Shoals reservoirs, South Carolina, 1990

Stevens Creek Reservoir and Neal Shoals Reservoir are located in the Piedmont Province of South Carolina (fig. 1). The primary purposes for the reservoirs are hydroelectric power generation and recreational activities. Because there has been no bottom surveys of these reservoirs since they were formed in the early 1900's, there is concern about the decrease in reservoir volumes due to sedimen- tation. An investigation was begun in 1990 by the U.S. Geological Survey (USGS) in cooperation with the South Carolina Department of Natural Resources, Water Resources Division to provide information on present water depths, on areas of rapid-sediment deposition, and on changes in lake volume. This report documents the bathymetric surveys made of Stevens Creek and Neal Shoals Reservoirs during 1990 and provides maps that depict the depth of each reservoir.
