Black/Brown Stones (10-14), Deerfield Stones (14) Rainbow and Case Caddis Czech Nymphs (10-14) Flash Back Pheasant Tails (14-18), Woolly Buggers (6-10). Be patient and fish deep and slow. Use colorful and flashy flies to attract the fishes attention. Be willing to change your techniques and retrieves and you could be pleasantly rewarded. Double and triple nymph rigs can be effective. Use a heavily weighted fly like a Tungsten Stone to get your other flies down. Attach your dropper flies about 18″-24″ apart.
