Black Run is a small stream, also called a tributary, located in Pennsylvania. It flows through parts of Lycoming County and Union County. This stream is about 3.6 miles (5.8 km) long.
Black Run eventually flows into the West Branch Susquehanna River. Its water is considered clean and healthy for fish. The area around the stream is a good place for fish that live in warm water and for fish that travel to lay their eggs.

Where Black Run Flows
Black Run starts in Brady Township, Lycoming County, near a pond. It flows generally south-southeast. The stream then leaves Lycoming County and enters Gregg Township in Union County.
As it flows, Black Run turns southeast. It passes through a pond and a wetland, which is a marshy area. Along its journey, it receives water from smaller streams, called unnamed tributaries. It also passes through another pond.
The stream then turns east and later east-southeast. It crosses a major road, US Route 15. After this, it turns northeast and then east, receiving more water from another small stream. Finally, Black Run turns northeast again, re-entering Lycoming County. It flows east-southeast for a short distance before joining the West Branch Susquehanna River.
Black Run meets the West Branch Susquehanna River about 20.34 miles (32.73 km) before the West Branch reaches its own mouth.
Water Quality of Black Run
The water in Black Run is considered clean. It is not listed as a polluted stream. In the past, some facilities applied for permits to release stormwater into its smaller streams. Also, a nearby facility once released treated water into Black Run.

Black Run's Watershed
The watershed of Black Run covers an area of 5.87 square miles (15.2 km2). A watershed is the entire area of land where all the rain and snowmelt drains into a particular stream or river.
Black Run is located entirely within the Montoursville South area on USGS maps. The end of the stream is near the town of Montgomery. The stream also flows near the northern border of Gregg Township in Union County.
Some important places are located within the Black Run watershed. These include the Allenwood Federal Prison Camp and the Lycoming County Landfill.
History of Black Run
Black Run was officially added to the Geographic Names Information System on August 2, 1979. This system keeps track of names and locations of places in the United States.
In the late 1800s, a tannery, which is a place that processes animal hides, used to release waste into Black Run. In 1990, there was a plan to build a new water treatment plant near the mouth of Black Run. This plant would have released a large amount of treated water into the West Branch Susquehanna River.
Animals and Plants in Black Run
The area where Black Run flows is known as a Warmwater Fishery and a Migratory Fishery. This means the water is suitable for fish that prefer warmer temperatures. It also supports fish that travel, or migrate, through the stream to lay their eggs.
