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—Common; Panfish—Common; Northern Pike—Present; not population counts.

Stocking records: 2 documented events through 1989, 3,725 fish total. Species: 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.

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 19 ft from 12 samples, latest sample 2025-08-21
Satellite clarity estimate: 13.43 ft (2016) — a remote-sensing estimate, kept separate from field measurements
Lake directory clarity class: Very Clear

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

AIS record: Chinese mystery snail — Verified (vouchered), latest documented 2009-07-15
AIS record: Eurasian watermilfoil — Verified (vouchered), latest documented 2005-09-08

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: Upper Wolf River Fishery Area (Wisconsin DNR); ≈0% of shoreline buffer
Shoreline development (landcover proxy, 2025 source): ≈27% developed land within 300 m, ≈4.7% impervious
Road proximity (TIGER proxy, 2025 source): nearest secondary road (U.S., state, or county highway) ≈17 m; ≈2.2 km of road per km² within 1 km
