How to Rig It

Single dry — too big for a dropper.

How to Present It

Dead-drift through slower seams. Big bugs don't move fast.

Why It Works

Green Drakes are the steak dinner of the river. When they hatch, even the biggest, most cautious trout slide up to feed in daylight.

History

The hatch is short (1-3 weeks) but legendary on rivers like Henry's Fork, the Frying Pan, and the Yampa.

Pro Tip

Bring a Green Drake spinner too — late afternoon spinner falls can be the day's best window.

Frequently Asked Questions

When is the Green Drake hatch?+
