What are good trout flies in Ohio during late september through october?

im planning on heading over to the mad river in west central ohio for some brown trout and rainbow trout fishing. Ive never caught a trout on a fly, and having practiced my technique on only bluegill, i dont know much about trout flies. I need to know what flies would match most naturally to local hatches, and what flies are GOT-TO-HAVE. BTW, its a small river/stream, tends to be pretty cold water. THANKS!

    Never fished the Mad River but since no one else seems to be stopping by, I can make some general recommendations.

    I’d guess that dry fly action in your area in the next two months is going to consist mostly of caddisflies and various mayflies and midges. Autumn hatches can be abundant and a blast to fish.

    The best thing would be to pray for a caddisfly hatch that you can fish in the evenings with an Elk Hair Caddis. Match the coloration and size and hang on to your pole. The Elk Hair Caddis is sturdy, easy to see, and easy to present. Because you’re usually fishing with size 12-16 flies, they’re easy to set and they stay put. You can fish the adult stage, emergers, and rising larvae with various patterns.

    So, if you see an insect that looks like this:

    fish with a fly that looks like this:

    or this:

    or this:

    Almost as good would be a mayfly or midge hatch on an overcast or rainy day that you could fish with Blue Wing Olives or other may fly patterns like Parachute Adams. This might happen in the early morning, but more likely it will occur in the afternoon and evening. If there’s no hatch, try a CDC Emerger with a strike indicator.

    So, if you see a fly that looks like this:

    fish with a fly that looks like this:

    or this:

    or this:

    You might see very small midges, like tiny black or brown gnats, hatching and swarming on the water. These can be imitated with one of my favorite flies, the Griffith’s Gnat:

    Very small Griffith’s Gnats (18 – 22) are more challenging to fish. They’re harder to see and harder to hook fish with, but you can fish some nice big fish on these tiny flies.

    No hatch? Try a Hopper on the surface or a Wooly Bugger under the surface, either one with a small nymph on a dropper — small Hare’s Ear, Prince Nymph, Brassie, or Zebra Nymphs.

    To zero in on the exact patterns and variations to use, where to fish, and when to fish, visit a fly shop and talk to the people who work there. Hatches are going to depend on weather, water temperature, and flow.

    Must-have dries: Blue Wing Olive in sizes 16 – 20. Pale Morning Dun in sizes 16 – 20. Elk Hair Caddis in sizes 12 – 16 (a couple different shades would be good). Various local favorite mayfly or midge patterns in sizes 16 – 22. Parachute Adams in sizes 12 – 18. Royal Wulff in sizes 12 – 16. Griffith’s Gnat in sizes 18 – 22.

    Must-have wets: Hare’s Ear Nymph in sizes 14 – 18. Pheasant Tail in sizes 14 – 18. Brassie in sizes 16 – 20. Woolly Bugger in sizes 10 – 14 (a couple different colors would be nice). Prince Nymph in sizes 14 – 18. Other local favorite nymphs in various patterns.

    Your mileage may vary! Talk to those fly shop guys or someone from your neighbornood. Like I said, I’ve never fished in Ohio and these are general guesses based on approaches that work most anywhere.
