Fishing on the Yellowstone has been good recently! Dry droppers have been the go to set up for us recently with thunder thighs, henneberry hoppers, donkey kongs, panty dropper hoppers, chubbies and soruce moths having the spotlight up top. For nymphs, duracell's, prince nymphs, hare's ears, copper john's, rubber legs, and various sizes and color perdigons have all been awesome out there recently. Streamer fishing can be awesome depending on the day as well with cloudy days being best, and with streamers the middle of the river has been better for bigger fish and the banks better for numbers. Smaller streamers have been crushing too with kreelex minnows, sparkle minnows, mini peanut envy's in olive, black or yellow have all been good for us.
