Poquettes Lake

Poquettes Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Burnett 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. At 96 acres, Poquettes Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Poquettes Lake sits at rank 41 of 70 in Burnett County, in the lower half of the local distribution.

An invasive species record — Chinese Mystery Snail — has been logged at Poquettes Lake; Wisconsin DNR maintains the official infested-waters list. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
