Plan your visit

• Lake directory: public landing — Yes
• Lake directory: public beach — Yes
• Lake directory: public park — No
• DNR public-access inventory: 1 documented access site record
• DNR public-access inventory: documented developed boat ramp
• DNR public-access inventory: 1 shore-fishing site record
• 2 sites qualify for per-site Directions through the reviewed lake association (load the site details below)

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 8 fish species/groups with abundance categories — categories are source labels, never a population count.

DNR fish labels: Walleye—Abundant; Catfish—Common; Musky—Common; not population counts.

Stocking records: 26 documented events through 2022, 41,265 fish total. Species: Muskellunge And Hybrids (Occasional), Bluegill (Historic), Walleye (Historic). Events in 2015 or later count as recent.

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: 17 normalized rows across 17 species entries. Normalized from the DNR ruleset retrieved 2026-08-04. Source text remains authoritative.

2026-2027 retained fishing rules: 17 published rows for 17 species; effective through 2027-03-07. Check current DNR rules.

Water and setting

• Satellite clarity estimate: 4.57 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.

Not published in the lake directory: official mean depth.

• AIS record: Curly-leaf pondweed — Verified (vouchered), latest documented 2007-07-09
• AIS record: Eurasian watermilfoil — Verified (vouchered), latest documented 2009-09-18
• AIS record: Purple loosestrife — Verified, latest documented 2007-07-09
• AIS record: Rusty crayfish — Verified, latest documented 2007-07-26

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: Brunet Island State Park (Wisconsin DNR); ≈83.2% of shoreline buffer
• Shoreline development (landcover proxy, 2025 source): ≈19.2% developed land within 300 m, ≈5.8% impervious
• Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈0 m; ≈3.2 km of road per km² within 1 km

• Priority Navigable Waterway — basis: musky area, walleye area
