Wolf Run (Muncy Creek tributary)

Wolf Run is a tributary of Muncy Creek in Lycoming County, Pennsylvania, in the United States. It is 7.6 miles (12.2 km) in length. The stream flows through Wolf Township, Muncy Township, and Muncy Creek Township. The stream's watershed has an area of 10.8 square miles. Slightly over two million pounds of sediment flow through the stream every year. A fort existed near Wolf Run for several hundred years until the late 1800s or early 1900s. At least three bridges cross the stream.

Wolf Run looking downstream

Wolf Run begins near the western border of Wolf Township, between Roundtop and Long Hill. It flows southwards inside a valley and turns southeast after some distance and then turns south again. In the southern part of Wolf Township, the stream leaves the valley, flows under U.S. Route 220, and turns southwest, exiting Wolf Township and entering Muncy Township. It gradually turns west and passes near the community of Pennsdale before turning south. Near the border of the township, the stream crosses under Interstate 180 and enters Muncy Creek Township. The stream turns west and then south again to parallel the West Branch Susquehanna River. Near the borough of Muncy, it reaches its confluence with Muncy Creek, very near to Muncy Creek's confluence with the West Branch Susquehanna River.

Wolf Run joins Muncy Creek 0.06 miles (0.097 km) upstream of its mouth.

Hydrology

Wolf Run experiences siltation and also experiences stream bank erosion.

The annual load of sediment flowing through Wolf Run is 2,166,200 pounds (982,600 kg). A load of 1,362,400 pounds (618,000 kg) of sediment per year comes from croplands, 503,000 pounds (228,000 kg) comes from stream banks, 116,800 pounds (53,000 kg) comes from forests, and 115,400 pounds (52,300 kg) comes from hay or pastures. 49,000 pounds (22,000 kg) per year comes from what is classified by the Pennsylvania Department of Environmental Protection as "low-intensity development" and 16,800 pounds (7,600 kg) per year comes from what is classified by the Pennsylvania Department of Environmental Protection as "transition". A sediment load of 2,800 pounds (1,300 kg) per year comes from the watershed's coal mines and none comes from the watershed's wetlands.
