Tips Fly Fishing on the Lower Colorado

Seasonal Tip

Focus on fishing the warmest part of the day and target deep pools and seams where trout are conserving energy.

Dry Fly

Dry fly action is minimal in winter, but sunny afternoons may bring sporadic midge and Baetis hatches.

Nymphing

A two-fly rig with a midge and Baetis nymph is your best bet. Use enough weight to get your flies down quickly in deeper water.
