Richmond County Lake Quality

Richmond County holds 13 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. 4 of those lakes carry an A–F grade. The county-level summary describes that subset, not every water body listed. The county-wide average lands at B — solid water quality with most lakes carrying clear summer transparency and low-to-moderate phosphorus.

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 Rockingham City Lake (A); the most-stressed is Roberdel Lake (C).
