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.

Fishing
The DNR lake page publishes 2 fish species/groups with abundance categories — categories are source labels, never a population count.
DNR fish labels: Largemouth Bass—Common; Northern Pike—Present; not population counts.
Stocking records: 4 documented events through 1988, 15,065 fish total. Species: Largemouth Bass (Historic). 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.

Water and setting
- Satellite clarity estimate: 9.83 ft (2017) — a remote-sensing estimate, kept separate from field measurements
Official DNR depth map (PDF) — Historical lake map; not for navigation. Link checked 2026-07-16.
- AIS record: Eurasian watermilfoil — Verified (vouchered), latest documented 1993-01-01
- AIS record: Phragmites (non-native ecotype) — Verified, latest documented 2023-08-19
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): ≈8.1% developed land within 300 m, ≈1.9% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈31 m; ≈1.4 km of road per km² within 1 km
- Priority Navigable Waterway — basis: lake under 50 acres
