When to fish rainbow trout in Wyoming

• 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.
