Covington County Lake Quality

Covington County holds 10 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. 3 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, Covington County sits comfortably above the Alabama median.

The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Ptac Lake (B); the most-stressed is Ptac Lake (B).
