The Yellowstone River is in full swing and fishing well. Grasshoppers continue to produce the most consistent fishing. Smaller terrestrials such as ants and beetles have the fish looking up as well. In the evenings especially, look for a lingering Caddis emergence and good fishing with nocturnal stone imitations. Mcknight’s Fat Boy has been a popular midnight stone fly pattern for us – more 10′s coming soon!
Double dry rigs and dry – dropper rigs are the way to go fish a stout 2x or 3x leader to your first fly with 4x to your dropper. The stout leader will help you turnover your flies and give you enough power to land the big one. Plus if you happen to hook a willow or rock, hopefully you’ll just loose your bottom fly.
Yellowstone Park has been fishing well, particularly the Lamar Valley. Look for terrestrials such as crickets, beetles, ants and grasshoppers to bring you the most action on Lamar, Soda Butte and Slough Creek. Be prepared with a few green drake or PMD imitations as well. As always the smaller creeks you find on your park map will fish well with attractor dries. Otherwise, it’s hopper time!
