I'm a SE PA guy- I haven't fished valley in a couple months or so but will be getting out today for a few hours before I have to switch gears and get some work done around the house before the ole lady makes me sleep on the couch. I'll check back in to let you know how I do.
Valley typically treats me pretty well, it's my home stream and I fish it frequently. I find it's a stream that if you aren't catching fish in the usual hangs you definitely need to change up your flies till you get a go (if they haven't spooked obviously). I had a day where I couldn't buy a fish on a black midge and I switched over to a cream midge same size, profile, same everything and started nailing them one after another. Go figure on a size 20 fly. Valley will either drive you nuts or make your drive home a very happy one!
The past year I've gotten skunked, had a 20+ fish day, and many average days so id say fishing is pretty good on an average.
