September 11th-Indian Summer for real!
Wow, what a beautiful weather forecast we have in store for the next 4 to 5 days. Sunny and 70 through the weekend promises to fulfill all the best qualities of Indian Summer in Yellowstone country. We are routinely dropping below freezing every night now, so expect the mornings to start out a little slow in the fishing department, but as the day warms so will the fishing. Terrestrials are going to play a key role in the next few days, especially in the afternoons. Baetis will also be around, but the nymph imitations will probably be more important than the adults. Look for caddis to come on strong, especially on the Firehole. Mahogany Duns should also show up on rivers like the Gallatin and Henry’s Fork. We still haven’t seen any drakes on the Lamar and Soda Butte, but I would expect them any time over there, and like all hatches can be very localized in one 100 yard stretch and not in another 100 yard stretch on the same day, so I easily could have missed them so far.Â
