How to Rig It

Single dry; pair with a Red Quill for the male phase.

How to Present It

Dead-drift down feeding lanes during the 1-4pm window when Hendricksons peak.

Why It Works

It nails the pinkish-tan body of the female dun — trout that ignore generic Adams will eat a true-to-color Hendrickson.

History

Named after A.E. Hendrickson, the fly was tied by Roy Steenrod on the Beaverkill in 1916 and remains a Catskill cornerstone.

Pro Tip

The hatch is short — 60 to 90 minutes. Be on the water by noon and ready to switch to spinners by 4pm.
