Terrestrial patterns are the way to go on all streams. Choose one you are sure to see on swifter streams, and delicate ones for slower waters. Horseflies and deer flies are rampart throughout.   No better pattern exists for simulating them than a standard humpy!  Another terrestrial pattern that is sure to work along wooded reaches are ones for spruce moths.  This is the peak of their season, and trout know it.
