How to use this ranking

When to fish largemouth bass in Oregon
- Spring 2–10 ft — Pre-spawn through spawn: target shallow flats, pockets and cover near deep access.
- Summer 8–20 ft — Fish the edges: weedlines, drop-offs, and deep cover close to shallow feeding areas.
- Fall 4–15 ft — Follow the baitfish: points and creek channels leading into pockets.
- Winter 15–35 ft — Slow and deep: steep drops and channel bends near wintering basins.
