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 brown trout in Alberta
- Spring 3–25 ft — Cold-water browns hug shorelines, river mouths and mud lines — often in a few feet of water early and late.
- Summer 25–60 ft — Browns sit at the thermocline by day and slide shallow after dark — the night troll takes the giants.
- Fall 5–30 ft — Spawn-run browns stage off tributaries and gravel shorelines, aggressive and territorial.
- Winter 5–35 ft — Browns feed all winter — nearshore when bait is in, deeper breaks otherwise.
