Plan your visit

• Lake directory: public landing — Yes
• Lake directory: public beach — Yes
• Lake directory: public park — Yes
• DNR public-access inventory: 1 documented access site record
• DNR public-access inventory: documented carry-in access
• 1 site 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.

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—Common; Panfish—Present; not population counts.

Stocking records: 4 documented events through 2022, 12,814 fish total. Species: Largemouth Bass (Rare), Bluegill (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: 19 normalized rows across 19 species entries. Normalized from the DNR ruleset retrieved 2026-08-04. Source text remains authoritative.

2026-2027 retained fishing rules: 19 published rows for 19 species; effective through 2027-03-07. Check current DNR rules.

Water and setting

• Field-measured summer Secchi clarity: median 7.6 ft from 4 samples, latest sample 2016-08-24
• Satellite clarity estimate: 12.33 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: Chinese mystery snail — Verified, latest documented 2012-06-27
• AIS record: Purple loosestrife — Verified, latest documented 2020-09-23
• AIS record: Yellow iris — Verified, latest documented 2016-06-30

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: Copper Falls State Park (Wisconsin DNR); ≈90.2% of shoreline buffer
• Shoreline development (landcover proxy, 2025 source): ≈10.9% developed land within 300 m, ≈1.5% impervious
• Road proximity (TIGER proxy, 2025 source): nearest secondary road (U.S., state, or county highway) ≈24 m; ≈2.2 km of road per km² within 1 km

• Priority Navigable Waterway — basis: lake under 50 acres
