Little Lac Courte Lake

Little Lac Courte Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all 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. A maximum depth of 46 ft puts Little Lac Courte Lake in the middle of Wisconsin's depth distribution. At 221 acres, Little Lac Courte Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Within Sawyer County's 50 graded lakes, Little Lac Courte Lake ranks 31 — below the local median, though not at the bottom.

Eurasian watermilfoil is established at Little Lac Courte Lake, which can dampen recreational access and pressure the native plant community. The fishery includes walleye alongside the lake's other 6 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.
