It would be hard to spot burn a stocked trout stream, if trout info is what the op is seeking. Hitorical warmwater/coolwater fish stocking info for streams, rivers, and lakes going back to about 1990 can typically be found on the PFBC web site. Earlier than that involves a year by year search of the binders that harbor those paper records. The electronic system crashed a year or more ago and I don’t know if those records are back up and running yet. I have not checked.
As for stream by stream historical adult trout stocking records, good luck with that. Had someone asked for that when I had them available to me for SE Pa I would have had to search year by year through the paper files to develop a historical record. I am not aware of any electronic data for adult trout that compared to those for fry, fingerling, and adult warmwater/coolwater species and for fingerling trout.
