Csmi 2021 Station Med Lake

Ashland County, WisconsinLimited DataOligotrophic

On the LakeGrade rubric, Csmi 2021 Station Med Lake pulls an A: clarity readings still being added and phosphorus readings still being added put it in the top bracket for Wisconsin. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. 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. Csmi 2021 Station Med Lake sits at rank 7 of 10 in Ashland County, in the lower half of the local distribution.

No invasive species are currently listed at Csmi 2021 Station Med Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Csmi 2021 Station Med 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.
