Plan your visit

• Lake directory: public landing — Yes
• Lake directory: public beach — No
• Lake directory: public park — No
• DNR public-access inventory: 1 documented access site record
• No site qualifies for per-site Directions: the reviewed association or a published coordinate is missing, which is a data state, never evidence about access.

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 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.

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 1 ft from 4 samples, latest sample 2018-08-20
• Satellite clarity estimate: 7.52 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 (vouchered), latest documented 2007-05-02

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: Ashland County Forest (Ashland County); ≈1.5% of shoreline buffer
• Shoreline development (landcover proxy, 2025 source): ≈5.5% developed land within 300 m, ≈0.6% impervious
• Road proximity (TIGER proxy, 2025 source): nearest local road or city street ≈24 m; ≈1.7 km of road per km² within 1 km
