Tulpehocken Creek is an outstanding tailwater fishery located just outside of Reading, Pennsylvania.The bottom release dam provides cool and fertile water from depths of up to 50 feet which keeps the Tulpehocken Creek cool enough for trout to thrive in the almost 4 miles of water below the dam, with heavy brown and rainbow trout averaging between 12-14 inches. The Tulpehocken Creek (the "Tully") is also influenced by two tributaries which help cool the lower stretches of the stream during the hottest summer months.
