Cheesman Canyon in the winter is not for the faint of heart—both in terms of the hike and the fishing. This legendary South Platte tailwater is running low and clear, making every trout hyper-aware of your presence. If you think you're stealthy, Cheesman will prove you wrong.
The key to success right now? Go tiny, go deep, and go slow. Trout are holding in deep pools and feeding selectively on midges and small Baetis patterns. 6X-7X tippet is a must, and light, drag-free presentations will get you into fish. While the scenery is stunning, this is a technical winter fishery, so bring patience, warm layers, and a solid game plan.

Tips for Fly Fishing Cheesman Canyon
Seasonal Tip
Fish are ultra-spooky—stay low, wade carefully, and make long, precise casts.
Dry Fly
Very little surface action, but small BWOs or midges may bring up a few fish in slow eddies on warmer afternoons.
Nymphing
This is the name of the game—small midges, light tippet, and long leaders will yield the best results. Adjust weight frequently to stay in the strike zone.
Streamer Fishing
Low flows mean big browns aren’t chasing much—but a slowly dead-drifted leech or small sculpin could still get a reaction.
