My two old roomies live pretty much on the river, or at least it is within walking distance anyways. They have since switched over to heavy sink tips, and big uglies, to get down to 'em. They are primarily targeting the oversized Browns that cruise around their area, but they have mentioned that just about any nymph that looks half real, will catch a fish or two. One of my favorites on that river has been the Czech nymphs in a variety of colors, from brown, to hot pink, and some emergents are killer too, but those are for a little later on in the year. I have also heard that very low in the system, the fish are waking up, and eating dries. Something else to consider. Maybe take two bug bashers. Have one for dries, and the other for sinkers. Good luck out there, it is a great river as you probably already know!
