Well Matt, you can check the PFBC web site, they found in a survey they found 7 brookies in the stream, only a few bass in the reservoirs and some other small populations of warm water species. When I fished there a couple of years ago I was greatly disappointed by this beautiful stream.
However there are other places to fish for large brookies that move out of reservoirs, though I won't reveal the names, I've fished about a dozen of them. Laurel Run along rt. 322 is supposed to have big browns, but after a day of fishing the stream in the fall, I'm not sure if they move out of the reservoir, we caught no big fish and only a few paultry brookies. I believe the stream to be imapcted by acid deposition.
Some others though can have very good fishing in the streams above. Go after a good rain and the trout move into the streams to feed. Again if the fall the trout move out of the reservoirs to spawn and some large trout can be found.
