There is still a small window of opportunity to get in on some of the giant stonefly action. If you havn't gotten out to witness this mayhem yourself, then now is the time! The Yellowstone, Madison and Gallatin rivers are all seeing solid hatches with the water as clear as one can imagine this time of year. All this is making for some great fishing with large dry flies and rubberleg droppers. An obvious choice is the chubby chernobyl #8-#12. Try not only the one with the golden belly, but also the peach and flesh tones. Girdle bug and Girdle bugger have been my dropper of choice. In addition to the big stonefly's recent activity on local waters; Pmd's, Yellow sallies, and Caddis are all hatching on a daily basis.
To sum things up...our rivers are active, fishing is great, and YOU need to get out there!
