Tips Fly Fishing on Boulder Creek

Seasonal Tip

Focus on fishing the warmest parts of the day when trout are more likely to feed. Approach carefully to avoid spooking the fish in this small water.

Dry Fly

Dry fly opportunities are rare in winter but possible during sunny midday midge hatches.

Nymphing

A two-fly rig with a midge and a small Baetis pattern is your best chance for success. Adjust your weight to get to the bottom of deeper pools.

Streamer Fishing

Use small, dark streamers fished deep and slow in shaded runs or undercut banks.
