Iso's in Sept.

Fished Penns Thursday Sept. 27 below Cherry Run, no not in some one's personal riffle! Got there about 10:00 AM and watched the stream and saw a few fish rise, put on a tan Iris caddis emerger, floated it over at least three good solid rising fish but no takes? I saw a Iso coming off the surface and decided to put one on, that was the last fly I put on, fished it all day and it accounted for 20 fish, 2 big rainbows, 3 big browns and the rest smaller but in very nice shape browns. The only problem was I forgot my dry fly shake material and it was hard to get it back in shape after each fish, I'll remember next time. My Iso emerger is just a smaller version of the one I use in the summer those tend to be very large size 10/12 and the fall guys are about 12/14- depends on your hook choice. I use Tienco 200 #14 with a dark olive grizzly shuck, dark red brown Aust. opossum body, a full looped old grey poly wing and light ginger hen hackle. Just treat the wing loop and float in to them, the fish took it all every way possible, splashy, head & tail or down stream, all good indications that they were locked on that insect. No one else around till I was leaving, some young dude started to fish in the riffle and I bet he did not have a pass to do so?
