Outstandingly Remarkable Values


The Allegheny provides the most populous freshwater mussel habitat in the world, and one tributary, French Creek, is one of the most biologically diverse watersheds in Pennsylvania. 


Named "La Belle Riviere" by French explorers, these 87 miles of the Allegheny flow through areas of narrow forest valleys, wilderness islands, and broad, rural landscapes rich with the early history and culture of the region.


Good public access and few hazards make this an ideal river for novice and family canoeing. Fishing for muskie, walleye, rainbow trout, and smallmouth bass is popular.


Pastoral farmlands, small towns, and the narrow winding valleys provide a diversity of views for those travelling the river.
