Plan your visit
- Lake directory: public landing — Yes
- Lake directory: public beach — No
- Lake directory: public park — No
- DNR public-access inventory: 1 documented access site record
- DNR public-access inventory: documented developed boat ramp
- No site qualifies for per-site Directions: the reviewed association or a published coordinate is missing, which is a data state, never evidence about access.
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 6 fish species/groups with abundance categories — categories are source labels, never a population count.
DNR fish labels: Panfish—Common; Walleye—Common; Largemouth Bass—Present; not population counts.
No fisheries survey population estimate is published for this lake in the covered report families.
- Musky reproductive status (DNR mapped): Natural reproduction plus stocking (Cat. 2)
Fishing limits — 2026-2027 season: 19 normalized rows across 19 species entries. Normalized from the DNR ruleset retrieved 2026-08-04. Source text remains authoritative.

Water and setting
- Field-measured summer Secchi clarity: median 6 ft from 37 samples, latest sample 2025-08-31
- Satellite clarity estimate: 3.93 ft (2017) — a remote-sensing estimate, kept separate from field measurements
- Lake directory clarity class: Low
Official DNR depth map (PDF) — Historical lake map; not for navigation. Link checked 2026-07-16.
- AIS record: Chinese mystery snail — Verified, latest documented 2008-06-06
- AIS record: Eurasian watermilfoil — Verified (vouchered), latest documented 2015-08-25
- AIS record: Rusty crayfish — Verified, latest documented 2002-12-31
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 1,000 ft; nearest: Thunder Lake Wildlife Area (SDNR); ≈0% of shoreline buffer
- Shoreline development (landcover proxy, 2025 source): ≈11.3% developed land within 300 m, ≈1.5% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈1 m; ≈3.6 km of road per km² within 1 km
- Priority Navigable Waterway — basis: musky area, walleye area
