I always go up to at least the Donley Cabin then fish up to Camp Site #9 or higher, so I can't speak to the lower stretch. I hear there are some fair sized browns down lower, but where I fish it's mostly all rainbows with an occasional brookie thrown in. If you go on up to where the road crosses over and heads away from the stream, that's supposed to be all brookie territory, but it gets real tight for casting up that way. Good luck, and I hope you have a good day.
Fly fishing - it's cheaper than a bass boat!
