Middle Fork of the Salmon River (Dagger Falls)
Synopsis: Incredible catch & release dry fly fishing for Westslope Cutthroat and Rainbows. Difficult to get into but worth the trip. You may not see another person fishing while there.
Flies: orange and yellow stimulators, Renegades, PMDs, Royal Wulffs and BWO’s. Copper John nymph droppers
Flies that work well on the Middle Fork include the following: Parachute Adams, Elkhair Caddis, Royal Coachmen, Royal Wolff, Yellow Humpy, Black Gnat, Stimulator, Sofa Pillow, Dave's Hopper and the Chernobyl Ant. In the deeper waters of the lower canyon (known as Impassable Canyon) a copper john dropper will fish lights out.
