When we finally found some good numbers of isonychia emerging, there were indeed trout rising too them, but there were an absurd number of cedar wax wings flying around plucking the duns out of the air. It was te most bird activity I'd ever seen on the river.
After I stuck one rainbow on an iso emerger the action started to slow, so I changed to a beetle. While I wasn't paying attention a huge brown took my fly. There wasn't much I could do about it, and even worse it was a fish I'v been trying to catch for a while now. He's always somewhere in that run. Next time... maybe.
The last light bite was funky. I'm not really sure what the fish were eating, but I did catch a couple and miss a ton on sedgehammer caddis.
Hard to beat trout on dry flies in late July, especially in cold fast flowing water!
