Salmonflies and Goldenstones are in peak activity and should be great to good for at least another 10-12 days.
There are some Yellow Sally’s mixed in with the big bugs too, and one thing we’ve found is the fish that have seen a lot of big flies float over their head often will come up confidently and sip the Sally right off the top!

PMD, PED, Caddis are all important now too. And never forget the Purple Haze on the Lower D!
