Usually, one of the best places to start when looking for information for a specific location (other than word of mouth or hoping that someone from the area is on a forum) is to check out the webpage of the state agency that regulates fishing in your state. Here in NY, it is the DEC (Department of Environmental Conservation). In many states, it is called DNR (Department of Natural Resources). In Pennsylvania, it's the Fish and Boat Commission. their site is at www.fishandboat.com . I'd give that a try to get started. starte with the links on the left - stocking and fisheries. I looked at the interactive maps, and other than boat launch info, not much comes up for Centre County.

Tight lines!

Edit: I found a trout stream listing at : www.http://fishandboat.com/waters_trout.htm This should really get you started.
