Fishing on the Yellowstone has been great recently! Dry fly fishing is in full swing with caddis lining the banks like crazy. For dry flies we recommend fishing patterns that sit low in the water like the cornfed caddis or the x caddis in various sizes and colors. The nymphing has been killer recently as well with caddis nymphs and worms crushing them out there along with perdigons and blowtorch's. Streamer fishing can be awesome depending on the day as well. Streamers of all sizes and colors have been working so it is good to continue switching flies if something was working earlier in the day for you and is no longer working anymore. A lot of people follow the adage of bright fly bright day dark fly dark day, but since everything is backwards this year with the weather, we have been finding better success with the opposite. Dull flies like the Ishiwata's super snitch, sculpzillas, micro headbanger, and baby gonga's have been crushing on bright days and for darker days fishing flies like the kreelex, sparkle minnow, short shank redemption, munchy minnow, drunk and disorderly, and swim coach's are all great bets.
