On the Metolius River you are going to want to bring a nymph rod and a dry fly rod set up for the foreseeable future. I like a 10 1/2′ 3 weight for the nymphing (usually Euro Style, but can pump out some indicator work with it if needed) and a 9′ 4 weight for dries. Having that 2nd rod set up to be ready as soon as the moment hits is very important. On the dry fly rod, set it up with a 12′ Rio Suppleflex 5x and add 2-3 feet of 6x. Add some 7x if they get picky, which can happen. 
Quite a few caddis trickling off, and occasionally the fish will be on the dries, but no doubt about it the fish are hot for a pupa and you’re going to want a Tan #14-16, and Orange #8-10 and Amber #12-14. 
Zebra Midges #18-22 and Mayfly nymphs #16-20 for BWO and PMD stuff, and #10-12 for Drakes, which are a long ways away from hatching, but getting mature now and moving around. 
Golden Stones, Eggs, Balanced Leeches and Euro Streamers will round out the nymphing rigging for sure. 
Someone on Sunday told me they saw PMD’s. I doubt it in February, but there is a chance they saw an early emergence of Cinygmula. Usually these yellow dudes are more of a March and April hatch, but on a spring creek almost anything is possible. 
Bull Trout have been eating a lot of the nymphs and leeches and small streamers mentioned above. But a big articulated streamer always has game.
