Poquettes Lake
Burnett County, WisconsinMesotrophic
Poquettes Lake earns an A — every scored parameter (clarity and phosphorus) rates among the best monitored waters in Burnett County. clarity and phosphorus rate similarly, so there is no obvious single lever to pull on watershed management.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. The lake bottoms out at 23 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 96 acres, Poquettes Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Among the 57 graded lakes in Burnett County, Poquettes Lake sits at rank 18, above the county median.
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 among the lake's 4 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
