Plan your visit
- Lake directory: public landing — No
- Lake directory: public beach — No
- Lake directory: public park — No
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 6 fish species/groups with abundance categories — categories are source labels, never a population count.
DNR fish labels: Largemouth Bass—Abundant; Panfish—Common; Smallmouth Bass—Common; not population counts.
Stocking records: 21 documented events through 2000, 902,145 fish total. Species: Muskellunge And Hybrids (Historic), Walleye (Historic). Events in 2015 or later count as recent.
Fisheries survey population estimates are published for this lake; survey estimates are historical point-in-time studies and are never compared or ranked here.
- Musky reproductive status (DNR mapped): Natural reproduction plus stocking (Cat. 2)
- Musky angling class — 2018 historical publication, not current status: Musky A1 — DNR trophy-water class
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 21 ft from 11 samples, latest sample 2025-08-09
- Satellite clarity estimate: 15.41 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 2004-10-15
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: Lake Millicent - Francis Island (Wisconsin DNR); ≈0% of shoreline buffer
- Shoreline development (landcover proxy, 2025 source): ≈17.4% developed land within 300 m, ≈2.1% impervious
- Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈0 m; ≈3 km of road per km² within 1 km
- Resource water (NR 102): Outstanding Resource Water (ORW) — NR 102.10(1m)3
- Priority Navigable Waterway — basis: musky area, walleye area, outstanding/exceptional resource water
