Lynx Lake

Vilas County, WisconsinOligotrophic

On the LakeGrade rubric, Lynx Lake pulls an A: clarity at 12.8 ft and 10 µg/L of phosphorus put it in the top bracket for Wisconsin. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. Lynx Lake reaches 20 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake is compact at 31 acres, with partial shoreline records and little volume to buffer nutrient inputs. Lynx Lake ranks 65 of 191 in Vilas County — solidly in the upper half of the local distribution.

Lynx Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at Lynx Lake, one of 6 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
