I just got back from a vacation out there and had a pretty good time on the McKenzie. I only know flies and would suggest a yellow stimulator behind a clear bubble if you're trying to get them to rise. I was fishing above Leaburg dam, but I would imagine the same stuff would work lower down. Mega Princes, Copper Johns, and bead head Pheasant tails worked well too if you want to use sub-surface stuff. Also got my first steelhead on a purple egg sucking leech...If I were spin fishing, I would put one a couple of feet below a castable weight and swing it through appropriate steelhead water.
