DHEC divides South Carolina into 8 major river basins or
watersheds. Together, these watersheds contain over 30,000
stream miles, 300,000 acres of lake water and 200,000 acres of
estuary. 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. Click on a watershed
to learn more about water quality in that basin. Did you know?
