Fisher Lake

On the LakeGrade rubric, Fisher Lake pulls an A: clarity at 24.6 ft and 17 µg/L of phosphorus put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Fisher 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. Among the 34 graded lakes in Iron County, Fisher Lake ranks 5 — in the top quartile locally.

No invasive species are currently listed at Fisher Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Fisher 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.
