The March Brown hatch on the McKenzie is a solid bet now. Again, they will be the prominent hatch but likely mixed with BWO’s and Caddis and Midges. Be prepared for the afternoon hatch and carry a 2nd nymphing rod too for efficient transfers between methods. I know Troy and Tonn from the FFP guide team have been over enjoying the Mckenzie and can run a trip for you over there anytime you’re ready.
