I don't have any specific patterns that are better than others but in more general terms I would say I have very good success with thorax dun and comparadun style dry flies. I believe sparseness is better than heavily hackled. Presentation and size is much more important than the fly.
There are dozens of Hendicksons, BWO's, Sulfurs, Cahills, etc but all of the really good flies are going to incorporate certain features that make them good fish catchers.
Put the fly within a few inches of the rise form, not too far above the fish, get a perfect drag free drift and the fish will most likely eat your fly.
Regarding subsurface flies it is hard to go wrong with Hare's Ear, Pheasant Tails, Prince, Some Baetis and Sulfur imitations and round it out with some caddis larvae and pupa and a few generic stonefly patterns.
For streamers a white marabou, a couple of Wooly Buggers in black and brown, a Black Nose Dace, and a couple of Clouser minnows.
