Plan your visit
- Lake directory: public landing — No
- Lake directory: public beach — No
- Lake directory: public park — Yes
Each statement is bounded to its named source; absence of a record is never evidence of no access. The DNR access database may lag reality; posted signs at the landing are authoritative.
Verify at the DNR public boat access program page.
Fishing
The DNR lake page publishes 5 fish species/groups with abundance categories — categories are source labels, never a population count.
DNR fish labels: Largemouth Bass—Common; Northern Pike—Common; Musky—Present; not population counts.
No fisheries survey population estimate is published for this lake in the covered report families.
Fishing limits — 2026-2027 season: 17 normalized rows across 17 species entries. Normalized from the DNR ruleset retrieved 2026-08-04. Source text remains authoritative.

Occurrence records come from a non-exhaustive DNR inventory; a record documents presence at observation time and a missing record is never evidence of absence.
- Public-land proximity (GIS proxy, not access evidence): mapped public land within 1,000 ft; nearest: Hartman Creek State Park (Wisconsin DNR); ≈71.1% of shoreline buffer
- Shoreline development (landcover proxy, 2025 source): ≈9.3% developed land within 300 m, ≈1.1% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈9 m; ≈2.3 km of road per km² within 1 km
- Mapped critical habitat: 1 sensitive-area polygon — ≈13.5 ac (≈96.1% of lake area), partial-waterbody scope
- Priority Navigable Waterway — basis: lake under 50 acres
