The park is a coldwater 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.
Ice fishing is permitted on Halfway Lake. Ice thickness is not monitored.
