Potato Lake

Potato Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI value of 40 puts Potato Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. 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. Potato Lake sits at rank 8 of 13 in Rusk County, in the lower half of the local distribution.

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