Re: Bald River Falls
I have fished the North a dozen or so times this year and have generally found the fish not to be overly picky. They'll hit just about any dry fly as long as you get a decent deaddrift. I use stimulators and caddis patterns size 12 to 16. If you're getting refusals, drop down a size or two and you'll probably start hooking up.
I think far more important is stealth. Stay low and wade carefully. These fish will spook easily with the water levels being what they are. My last trip up there was about a month ago the stream was very low then and gin clear. The fish were more than willing to hammer dry flies, but man you had to be sneaky to get a shot at them.
Good luck! I hope you post a report on your trip.
