Korn's Oatka Stone Fly

Well folks, I fished again yesterday and took several nice brown trout on Oatka Creek which is about 45 minutes away from my home here in New York. We've been having a good little black stone fly hatch and this fly is just the ticket.

I developed this fly to fish Oatka Creek in April and May when these little black stone flies hatch. The fly only has 2 or 3 materials depending on how you tie it. It’s a versatile fly that works best as a trailing fly and can be fished with (dry) or without (emerger) “Frog’s Fanny” floatant. Used as a lead dry fly it can be hard to see on the water.

Variations include; cutting the CDC wing short for use as a nymph, adding a bead head, body and wing color, caddis variations minus the tail...

with over-wing

without over-wing


Hook: MFC #7000 dry fly std. #12-16 photo is 14
Thread: Uni 8/0 brown
Tail & body: Turkey tail feather 8-10 vanes, tied in at bend to form short tails. Then wrapped forward over superglue to form body to one eye length behind hook eye.
Wings & legs: 2 black CDC feathers, tied flat, shank length plus gap of hook. Feather butts are folded back on each side to form head and legs. Butts trimmed to 2/3rd of the body length on each side. These act as legs and out-riggers. Whip finish behind the head.
Over-wing: hen grizzly, vanes pulled back and tied in behind head.
Note: Superglue over-wing at whip finish.


  1. Is it too late to fish this pattern on the Oatka?

  2. Doug you can fish this pattern as soon as you see some of the black stones in April through about the end of May - early June.
