I've been fishing up there with no generation with pretty good luck.
I'm not a great fisherman, and just started fly flishing this year. The spots I like are below the weir in the current. Below that island at weir are some really big holes that fish well. Another 1/4 mile downstream there is a ledge you could wade out on that has been producing well. Most fisherman seem to do the Miller's Island loop, but I am not familiar with that. I was there last week and caught 9 or so. Seven were over 11 inches(Browns, Rainbows, and a brookie), and I caught a nice 16 inch brown. Like another Norris regular on this board suggested try a worm as your dropper, they work great. The flies I caught fish on were an olive beadhead. I tried a brassie but it just pulled up the gunk from bottom of river and was a pain to pull off each time.
