Stocking records: 11 documented events through 2016, 67,307 fish total. Species: Bluegill (Occasional), Largemouth Bass (Occasional), Northern Pike (Occasional). Events in 2015 or later count as recent.
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): none mapped within the search cap; ≈0% of shoreline buffer
- Shoreline development (landcover proxy, 2025 source): ≈11.8% developed land within 300 m, ≈1.8% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈36 m; ≈2.1 km of road per km² within 1 km
