If stocked trout are satisfactory, start downstream and stay an hour or so, varying your approach and technique. If the fishing is weak, move upstream a mile or more and sample the stream the same way, and so on. If you have patience, you will find good fishing.
I suspect, barring extreme low-water, that the stocked portion and even downstream areas will still hold trout. At some point, you may need to park and walk.
Sorry I don't have any real-time advice.
PS: this thread is particularly suited for the Fly Fishing Locations forum. I'd like to move it there. I think it gets as much traffic as the General Forum, but maybe not so many replies, simply because of the subject matter. At the same time, it categorizes your inquiry and makes searching and sorting more helpful.
