Stocking records: 6 documented events through 2022, 37,968 fish total. Species: Walleye (Occasional). Events in 2015 or later count as recent.
No fisheries survey population estimate is published for this lake in the covered report families.
- Musky reproductive status (DNR mapped): Natural reproduction plus stocking (Cat. 2)
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.
