When to fish kokanee in Colorado

• Spring 10–30 ft — Schools roam the upper column over open water while it's cool — short leaders, slow trolls.
• Summer 30–70 ft — Kokanee compress into the 50-55°F band at the thermocline over the deepest basins — precise depth is everything.
• Fall 5–40 ft — Spawners turn crimson and gang up off tributary mouths and gravel shorelines; remaining fish scatter with turnover.
• Winter 20–80 ft — Deep suspended schools — an electronics game through the ice.
