How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish rock bass in Pennsylvania
- 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.
