Wp22-T2b Lake

Douglas County, WisconsinLimited DataOligotrophic

Wp22-T2b Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Douglas County. 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. Among the 40 graded lakes in Douglas County, Wp22-T2b Lake ranks 8 — in the top quartile locally.

No invasive species are currently listed at Wp22-T2b Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Wp22-T2b 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.
