    • Black Run is a tributary of the West Branch Susquehanna River in Lycoming County and Union County, in Pennsylvania, in the United States. It is approximately 3.6 miles (5.8 km) long and flows through Brady Township in Lycoming County and Gregg Township in Union County. The watershed of the stream has an area of 5.87 square miles (15.2 km2). The stream is not designated as an impaired waterbody. It is a relatively small stream with its mouth located near Montgomery. The stream's watershed is designated as a Warmwater Fishery and a Migratory Fishery.


    Course


    Black Run begins to the east of a pond in Brady Township, Lycoming County. It flows south-southeast for several tenths of a mile before exiting Brady Township and Lycoming County. Upon leaving Lycoming County, the stream enters Gregg Township, Union County and turns southeast for several tenths of a mile, passing through a pond, receiving an unnamed tributary from the left, and passing through a wetland. It then passes through another pond, where it receives an unnamed tributary from the right. The stream then turns east for several tenths of a mile before turning east-southeast for several tenths of a mile. In this reach, it receives an unnamed tributary from the left. The stream then turns northeast, crossing US Route 15, before turning east and receiving an unnamed tributary from the left. After a few tenths of a mile, it turns northeast for a few tenths of a mile, reentering Brady Township, Lycoming county. The stream then turns east-southeast for a few tenths of a mile before reaching its confluence with the West Branch Susquehanna River.
    Black Run joins the West Branch Susquehanna River 20.34 miles (32.73 km) upstream of its mouth.

    Black Run is not designated as an impaired waterbody. The Lycoming County RMS Recycling Facility and the Lycoming County RMS Southside Stockpile once applied for a permit to discharge stormwater into an unnamed tributary or tributaries of the stream. The Federal Correctional Complex, Allenwood has discharged effluent from its wastewater treatment plant into the stream.
