Antigo Lakes

Antigo Lakes sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

At a TSI of 54, Antigo Lakes reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 32 acres, Antigo Lakes sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Antigo Lakes sits at rank 24 of 33 in Langlade County, in the lower half of the local distribution.

Antigo Lakes has no invasive species recorded in Wisconsin state databases as of 2026, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Antigo Lakes, 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.
