Fisher Lake

Fisher Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Wisconsin norms.

A TSI near 47 places Fisher Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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. Fisher Lake ranks 11 of 33 in Iron County — solidly in the upper half of the local distribution.

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.
