When to fish rock bass in Ontario

• Spring 2–10 ft — Spawners crowd shallow rock and gravel — anything small dropped near a boulder gets eaten.
• Summer 5–20 ft — Wherever there is rock there are rock bass — small jigs and crawler pieces along the boulder edges.
• Fall 8–22 ft — Schools tighten on deeper rock piles and steep banks — easy limits once you find one.
• Winter 12–30 ft — Wintering schools hold on the deepest rock — small tungsten jigs through the ice.
