Browsing the Laws in PA. As an "individual", you will not "legally" be able to stock any aquatic species in any of the state waters.

They do have a neat Cooperative Nursery program, but you have to have a legal setup with board members, bylaws and all that jazz, but you'll get a free Colonoscopy thru the process.
(means they'll just check you out really good)
You mentioned a conservation club? (which would be appropriate by law) Maybe you can find out more about this group and join.
If you just start tossing fish in on your own, and they find out, you will not want to be you!
Michigan is pretty easy about this for an individual wanting to help out. It's a free permit with a process involved, but you have to buy the fish from certified disease free sources. Can't just pull them out of your pond or a tank in your garage or basement and toss them in the river.
PA has some pretty strict law's, as do most Great Lake States. One permit I ran across, that had no explanation, was a permit to extend Trout fishing season in a private pond. That one for me, has a couple question marks on it??
To give you a perspective on this. The only fish your allowed to put into a State BOW, is one that you caught out of that same State BOW.
It's nice that you want to help tho, but there are protocols, procedures, rules and regulations.
