Indian Lake

The LakeGrade rubric puts Indian Lake at a C: clarity readings still being added, 34 µg/L of phosphorus, and a TSI of 55 signal an intermediate trophic state. 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.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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. Indian Lake ranks 123 of 140 in Oneida County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Indian Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Indian Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
