Lynx Lake
Vilas County, WisconsinLimited DataOligotrophic
Lynx Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. 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 178 of 202 in Vilas County — at the lower end of the locally monitored 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.
