PA Fish and Boat Class A Wild Trout · Spruce Creek Fly Fishing

The Little Juniata is central Pennsylvania's premier limestone tailwater trout fishery — 15 miles of fly-fishing-only wild trout water between Tyrone and Spruce Creek, with wild brown trout reaching 20 inches. The river's productive limestone chemistry and cool temperatures support dense hatches and trophy trout, and it is considered one of the finest limestone streams east of the Mississippi.
