When to fish brown bullhead in Ontario

• Spring 2–8 ft — First warm rains pull bullheads into black-bottomed bays and creek mouths — the classic spring shore bite.
• Summer 3–12 ft — Day fish hold on deeper mud and weed edges; after dark they spread across the shallows to feed by smell.
• Fall 5–15 ft — Fish slide toward deeper soft bottoms as the shallows cool — the evening bite shortens with the days.
• Winter 10–25 ft — Bullheads pod up half-dormant in the deepest mud basins; a long soak with bait on bottom is the lone play.
