Fawn Lake

On the LakeGrade rubric, Fawn Lake pulls an A: clarity at 29.5 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 28 puts Fawn Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake is compact at 19 acres, with partial shoreline records and little volume to buffer nutrient inputs. Fawn Lake ranks 39 of 202 in Vilas County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Fawn Lake — the lake remains off the Wisconsin infested-waters roster. Walleye are documented at Fawn Lake, one of 5 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
