The park is a coolwater fishery, stocked with brown, rainbow, and brook trout.
With the exception of the swimming area, the lake and its tributary streams are open to public fishing. The Pennsylvania Fish and Boat Commission stocks the lake and Rapid Run regularly during the season.
Many anglers gather near the sandstone dam or the fishing pier.
Pennsylvania Fish and Boat Commission laws apply. Complete information about fishing rules and regulations in Pennsylvania is available from the Pennsylvania Fish and Boat Commission.
