Dunn Lake

Dunn Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Vilas County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Dunn 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. Dunn Lake is small — 77 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Dunn Lake ranks 97 of 202 in Vilas County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Dunn Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 3 documented species across the lake's records. 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.
