How to Rig It

Single fly on a downstream swing, or as a dropper off a dry fly.

How to Present It

Cast across and downstream, let it swing through the run. Strikes are violent — let the rod load before setting.

Why It Works

The soft partridge or hen hackle pulses on the swing exactly like an emerging insect's legs and gills, triggering aggressive strikes from trout that have ignored dead-drifted nymphs all day.

History

Soft hackles date to 1800s England. The technique fell out of favor when indicator nymphing took over — and is now experiencing a renaissance.

Pro Tip

When indicator nymphing stops producing, swing soft hackles through the same run. You'll often discover the river was full of fish you weren't reaching.

Frequently Asked Questions

How do you fish a soft hackle?+

Cast across-stream, mend once, and let the fly swing on a tight line through the run. Strikes happen at the end of the swing as the fly rises in the column.
