Stone County Lake Quality

Missouri, 16 lakes, average grade B (Good)

Stone County's 16 graded lakes fall in the moderate-density bracket for Missouri. The county-level average smooths over real differences — a single agricultural watershed near the southwest corner can pull the average down even if the rest of the county runs clean. With an average grade of B, Stone County sits comfortably above the Missouri 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 Table Rock Lk. Into Main Channel From Dam Lake (B); the most-stressed is Table Rock L. @ Hampton Hollow Lake (F).
