And on the McKenzie River I know the guides association ran the stocking boat down the river recently, and there is a good mix of hatchery rainbows, wild rainbows and whitefish and some other catches of occasional cutthroat and bull trout. Targeting bull trout is not allowed on the McKenzie, but from time to time they get caught on a nymph or streamer while fishing for the other trout. 
Eric and Troy both report that the weed growth is heavier than normal, and they are being careful to not fish their clients nymphs or streamers too deep, instead relying on a short dropper tag off a dry fly, or being thoughtful about how much tippet is below the sighter to keep the nymphs from getting covered in green gunk. Eric had a lot of luck on red perdigons and small leeches, and Troy reports purple haze, McKenzie caddis, yellow sally and chubby’s.
