Indian Lake

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

Trophically, Indian Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 21 ft puts Indian Lake in the middle of Wisconsin's depth distribution. Indian Lake is small — 16 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Among the 32 graded lakes in Langlade County, Indian Lake ranks 4 — in the top quartile locally.

Indian Lake has no invasive species recorded in Wisconsin state databases as of 2021, though prevention practices still apply at all access points. The fishery is bass-led, with 2 documented species across the lake's records. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
