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 flathead catfish in Louisiana
- Spring 5–20 ft — Pre-spawn fish feed hard near wood cover and hole edges.
- Summer 8–30 ft — Day = log-jam lairs and deep holes. Night = shallow flats and bar edges with big live bait.
- Fall 10–35 ft — Fish concentrate near wintering holes — the year's best big-fish window.
- Winter 20–45 ft — Stacked and sluggish in the deepest holes.
