Berkeley County Lake Quality
South Carolina, 1 lake, average grade B (Good)
Only 1 lakes in Berkeley County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. With an average grade of B, Berkeley County sits comfortably above the South Carolina median.
Most of the county's monitored lakes are shallow — under 50 feet — which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Lake Moultrie (B) is the cleanest in the county.
