Lawrence County Lake Quality
Alabama, 4 lakes, average grade B (Good)
Lawrence County holds 4 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. 2 of those lakes carry an A–F grade. The county-level summary describes that subset, not every water body listed. With an average grade of B, Lawrence County sits comfortably above the Alabama 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. Sinl Lake (A) is the cleanest in the county.
