Rauchtown Run is a stream in Pennsylvania with extraordinary cold water and a wild trout fishery. At times this little brook is only feet wide and centimeters deep, nevertheless the waters hold wild brook trout. Rauchtown Run flows through the eastern portions of Clinton County and into the southwestern corner of Lycoming County where it sinks underground in Limestone Township and emerges as Antes Creek in the same township before joining the West Branch Susquehanna River near Jersey Shore. On U.S. Geological Survey maps, it is named Rauchtown Creek. The total length of Rauchtown Run and Antes Creek is 9.4 miles (15.1 km).[1]
