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 3 fish species/groups with abundance categories — categories are source labels, never a population count.
DNR fish labels: Largemouth Bass—Common; Northern Pike—Present; Panfish—Present; not population counts.

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): none mapped within the search cap; ≈0% of shoreline buffer
- Shoreline development (landcover proxy, 2025 source): ≈17% developed land within 300 m, ≈4.8% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈14 m; ≈3.4 km of road per km² within 1 km
