DHEC divides South Carolina into 8 major river basins or watersheds. For each of the 8 basins, DHEC produces a Watershed Water Quality Assessment (WWQA) that describes a wealth of information through text and maps including: water chemistry, biological monitoring, physical characteristics, natural resources, growth potential, potential nonpoint source contributions and point source discharges.
