The most patriotic fly out there.. The Bald Eagle fly pattern is a streamer pattern fished anywhere big trout might be lurking. This searching pattern can resemble a number of things in the river from sclupins to leaches. I like to switch up the color scheme to make it even more versatile. One of my favorite combinations would be purple and peach/pink for salmon species. Swing this fly and let the stinger hook do the work.
