Falk Lake

Falk Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Burnett County. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

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. A maximum depth of 30 ft puts Falk Lake in the middle of Wisconsin's depth distribution. Falk Lake is small — 76 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Falk Lake sits at rank 44 of 70 in Burnett County, in the lower half of the local distribution.

Falk 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. Walleye are documented at Falk Lake, one of 4 fish species on record for the lake. A documented public access point at Falk Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
