When to fish brown trout in Wyoming

• 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.
