West Branch Susquehanna Subbasin

Geographic features: Originating in the low rolling hills of the Allegheny Mountains in Pennsylvania, the West Branch flows northeast passing the steep hillsides of the Allegheny High Plateaus Section. At Renovo, the West Branch turns southeast and cuts through the Allegheny Front entering a region of broad valleys separated by long, high ridges. Following the northern flank of Bald Eagle mountain northeastward, the West Branch turns south to its confluence with the Susquehanna River near Sunbury.

The subbasin is covered predominantly by forest lands, especially in the northern and western ends of the subbasin where land is less suitable for agriculture. Extensive coal mining is the major land use activity in the western parts of the subbasin. Agricultural and urban lands are primarily located in the eastern and southern parts of the subbasin. Larger communities include State College, Lock Haven, Williamsport, Clearfield and Lewisburg.
