Plan your visit

• Lake directory: public landing — Yes
• Lake directory: public beach — No
• Lake directory: public park — Yes
• DNR public-access inventory: 8 documented access site records
• DNR public-access inventory: documented developed boat ramp
• DNR public-access inventory: 1 shore-fishing site record
• 8 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 4 fish species/groups with abundance categories — categories are source labels, never a population count.

DNR fish labels: Largemouth Bass—Abundant; Northern Pike—Abundant; Walleye—Abundant; not population counts.

Stocking records: 148 documented events through 2024, 132,907,228 fish total. Species: Walleye (Frequent), Bluegill (Frequent), Northern Pike (Frequent), Largemouth Bass (Historic), Channel Catfish (Historic), Crappies (Historic), Catfish (Historic), Rock, Yellow, And White Bass (Historic), Flathead Catfish (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.

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

Water and setting

• Field-measured summer Secchi clarity: median 0.8 ft from 50 samples, latest sample 2025-08-27
• Satellite clarity estimate: 2.77 ft (2017) — a remote-sensing estimate, kept separate from field measurements
• Lake directory clarity class: Very Low

Official DNR depth map (PDF) — Historical lake map; not for navigation. Link checked 2026-07-16.

• AIS record: Curly-leaf pondweed — Verified (vouchered), latest documented 2013-06-14
• AIS record: Eurasian watermilfoil — Verified, latest documented 1993-11-01
• AIS record: Zebra mussel — Verified, latest documented 2025-08-19

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): mapped public land within 1,000 ft; nearest: Scattered Wildlife (Wisconsin DNR); ≈7.7% of shoreline buffer
• Shoreline development (landcover proxy, 2025 source): ≈32.7% developed land within 300 m, ≈9.3% impervious
• Road proximity (TIGER proxy, 2025 source): nearest secondary road (U.S., state, or county highway) ≈0 m; ≈3.6 km of road per km² within 1 km
