Just do what all the guides on that river do: fish a pegged bead with split shot under an indicator. Or, if you don't want to be damned to eternal life in a lake of fire, swing just about anything. Lots of guys nymph, whether it be stoneflies, larger copper johns, and other buggy stuff or - eccchhh - trout beads. If that's your thing, go for it. As Big Tuna noted, dark marabou spiders swung on a sink tip get it done, particularly in low light conditions. I could tell you his go to color combo but then he would have to kill me. Black or purple string leeches, articulated leeches, tube flies, egg-sucking woolly buggers or leeches swung on a tip work too. So do things like skunks, wooly buggers, muddlers, general practitioners, etc. fished on light tips or maybe even a floating line. You can even catch them on the surface with stuff like greased liners, bombers, or Bill McMillan's steelhead caddis and other skaters and wakers. I remember a few years ago running into a guy who caught a fair number fishing a greyish muddler with a floating line - he would basically flip the fly behind rocks and in other pocket water and whammo - fish on. Just about everything works (or used to work) over there. The biggest problem now - particularly because it is such a small river - is that it gets absolutely hammered, so it has become harder to find undisturbed fish that respond well to traditional tactics. There is a large flotilla of guided and non-guided rafts that row laps through every decent spot of holding water dead drifting beads until they've fished the pool out. Last year was a mandatory 4-fish per day kill fishery on hatchery fish so it didn't take long for this armada of death to remove fresh fish that entered the river. I think the bobber/bead crowd has even scared a lot of the gear guys away, although we did see a guy in toon pulling plugs last year! Seriously, it's a great little fishery if you don't mind the crowds. If you happen to get lucky and be there when there is a fresh pulse of fish that hasn't seen 2,643 trout beads before they see your fly, you actually stand a good chance of catching fish. (I'm exaggerating a few of the downsides of the current Methow experience, but not by much.)
