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 summer flounder (fluke) in Connecticut
- Spring 5–25 ft — Fish move in from the ocean through inlets — drift bucktails along back-bay channel edges as water warms.
- Summer 8–35 ft — The classic drift: bucktail + strip bait bounced along sand next to structure, channel edges and lumps.
- Fall 12–45 ft — Fish stack at inlet mouths and deep channels before sliding offshore — the biggest fish of the year eat now.
- Winter 20–60 ft — Most fish winter offshore; a few holdovers sit in the deepest bay holes — a slow bottom rig on mild afternoons.
