Alright so you're in Dutchess county NY, I'm in Fulton County.
I have a tried and true pattern I always use for Pickerel, Pike, and Smallies and they seem to love it.
Henderson Perch
1. You wrap with black thread.
2. Start at the back with yellow chenile.
3. About 3-4 wraps of the chenile tie in some orange bucktail on the bottom and trim it short to perch fin length.
4. Then wrap the chenile farther forward and about 2/3rds of the way to the front of the hook wrap another orange fin on bottom.
5. When you get to the eye of the hook, tie in green bucktail with holographic flash on top.
6. Bulk up the head with the black thread, dot a yellow eye on each side of the head.
7. Tie a few up, tie one on in a lake or river that has Pickerel, Pike, or Smallmouth Bass and on a fast strip you'll be sure to pick up a few good fish.
Just understand that even though Pickerel are a typically smaller version of a Pike, they still have teeth, and I would be using either Tyger wire, or very strong tippet, that you can set the hook without them getting near the tippet.
Good luck, and any questions about the fly, or others that I use up here for pickerel, pike and smallies just let me know.
By the way, if anyone has a kayak. Take it out on a lake that has either of these 3 species and let them drag you into rocks and weed beds. Its a whole different experience in fly fishing.
