Franklin County Lake Quality

New York, 9 lakes, average grade B (Good)

Franklin County has 9 graded 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. With an average grade of B, Franklin County sits comfortably above the New York 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 Little Clear Pond (A); the most-stressed is Deer River Flow Lake (F).
