Person County Lake Quality
North Carolina, 6 lakes, measured by NC DEQ
Person County has 6 monitored lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. 3 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. For Person County the spread behind the average matters more than the average itself: a few nutrient-rich lakes among many clear ones produce the same figure as the inverse.
The county's lakes lean shallow, which makes the readings sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest measured lake is Mayo Reservoir.
