I live and grew up in St. Marys, Elk Co Area. And like the other guys said the streams are extreemly low! We need rain so bad here!!! But if you do want to at least try some streams then i would try the east branch of the clarion below the dam(artificial only section below the dam) the live bait section is from the east branch bridge on down. The east branch is really really cold coming out of the bottom of the dam. Also try the Main Branch of the Clarion between Johnsonburg and Ridgeway Its Trophy Trout waters C&R All Tackle. Very very nice big browns in there but like i said its very low. One thing the Main Branch of the Clarion has going for it during low flows of the summer months is that its got Big and Deep holes in it. I know a few holes 10 to 15ft+ deep even when its low. But try to fish faster water comming into a big deep hole.
I would be more then happy to help ya out while your here. Ill send ya a PM with my Cell and you can text or give me a call if you got any questions on where to fish.
Fishing, Turkey Hunting, Shed Hunting, Archery Hunting yep that's it!
