The whole gorge is spectacular. You might consider taking a slightly heavier rig along and some large streamers or big hair bugs/mice; there's some very large muskies in the deeper pools (even upstream out of the wild-n-scenic reach), and you might be surprised to pick up some better than average smallmouth on those same flies. Find large downed trees in water deeper than 4' and it's very likely there's a muskie home, or at least nearby. Be ready to try to trigger following fish.
