Bullhead Lake

Bullhead Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. 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. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within Langlade County's 33 graded lakes, Bullhead Lake ranks 19 — below the local median, though not at the bottom.

No invasive species are currently listed at Bullhead Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Bullhead Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
