Quarry Lake

Quarry Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Chlorophyll-a is the limiting factor: even when clarity looks acceptable, the algal community drives the grade down.

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 Brown County's 3 graded lakes, Quarry Lake ranks 2 — below the local median, though not at the bottom.

No invasive species are currently listed at Quarry Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Quarry Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Multiple sampling years from the Wisconsin DNR Citizen Lake Monitoring Network back the grade, so the letter should hold steady absent a major watershed shift.
