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 southern flounder in Texas
- Spring 2–15 ft — Post-winter fish set up at marsh drains and creek mouths — work a jig-and-minnow along the bottom seams.
- Summer 3–18 ft — Ambushers hold on channel edges, pilings and bar drops — a mud minnow or paddletail dragged slow.
- Fall 5–25 ft — The fall run — every flounder in the estuary funnels to the passes and jetties before spawning offshore.
- Winter 15–40 ft — Most spawn offshore; stragglers hold in deep channels — slow winter fishing, but the fish that eat are quality.
