Fly Fishing to Selective Smallmouth Bass

I was floating the North Fork of the Shenandoah River on a beautiful evening in late May when there was a very heavy caddis hatch on the river. Fishing a Mr. Rapidan Delta Wing Olive Dry Caddis I caught many nice bass. As I drifted into a long deep pool I decided to experiment. Fishing my favorite nymphs and streamers in every part of the pool produced only a few small bass. I put my dry caddis back on and caught a bass every second or third cast.
