Gull Lake

Gull Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. 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. Gull Lake reaches 19 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 178 acres, Gull Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Within Burnett County's 57 graded lakes, Gull Lake ranks 36 — below the local median, though not at the bottom.

Gull Lake has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. 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.
