FISHING TIPS
Water Type
Fast moving water
Nymph
Bounce nymph off the bottom in fast currents.
Dun
Float the fly on the main currents. Trout are very selective so patterns should be a very close match. Comparadun or Haystack on #12 or #14 are the best bet. If no takes from the feeding trout, "dorothea" may be the preferred hatch. Vitreus may also be a possibility.
Spinner
Mating occurs over riffles where the eggs are dropped. Dead drift an exact imitation over riffles. If no action think "dorothea".
