Tips Fly Fishing on Cheesman Canyon

Seasonal Tip

Winter fishing in Cheesman requires stealth, patience, and precise presentations. Focus on areas with slower currents and deeper water.

Dry Fly

Dry fly opportunities are rare but can be productive during midday hatches in sunny conditions.

Nymphing

A two-fly nymph rig with a midge and a small Baetis pattern is the go-to setup. Use fluorocarbon tippet and adjust weights to reach the strike zone.

Streamer Fishing

Streamers can entice larger trout in the canyon, especially when fished deep and slow along seams and undercuts.
