I am surprised people are catching fish in this high of water but they are. Depending on where you access, its been good on Girdle Bugs and other heavy Stonefly Nymphs and Sculpins. Droppers like the Purple Psycho Prince and Flash Back PT are good, and the Jig Style Possie Bugger is a smart choice to match smaller Stonefly Nymphs or March Brown Nymphs.
I’ve heard of some Skawla hatches near Crooked River Ranch.
I’ve also had some local customers tell me that even though they are not seeing March Brown hatches they are picking up fish on the dry mid day. My guess is you won’t see good MB Hatches until sometime in early to mid April.
