Langlade County Lake Quality
Wisconsin, 32 lakes, average grade A (Excellent)
Langlade County's 32 graded lakes fall in the moderate-density bracket for Wisconsin. 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. On average, Langlade County lakes grade an A. That puts it near the top of the Wisconsin county ranking.
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 Horseshoe Lake (A); the most-stressed is Dynamite Lake (C).
