Lynx Lake

Vilas County, WisconsinOligotrophic

On the LakeGrade rubric, Lynx Lake pulls an A: clarity at 39.4 ft and 10 µg/L of phosphorus put it in the top bracket for Wisconsin. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Trophically, Lynx Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Lynx Lake ranks 76 of 202 in Vilas County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Lynx Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Lynx Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
