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 rainbow trout in Maryland
- Spring 5–20 ft — Post-ice-out trout roam shallow; fish inflows and windblown shorelines.
- Summer 8–30 ft — Rainbows hold near cold inflows, current seams and the thermocline — find the cool water and you've found the fish.
- Fall 10–35 ft — Fall feeding on rock shoals, current and channel edges as water cools.
- Winter 8–40 ft — Trout are comfortable in cold water — one of the best winter targets; streams and tailwaters fish shallow, deep lakes hold on basin edges.
