Mahanoy Creek looking downstream, below all its named tributaries

There are eleven officially named tributaries of Mahanoy Creek, a 51-mile-long (82 km) tributary of the Susquehanna River in Schuylkill County and Northumberland County, in Pennsylvania, in the United States. Of these, six are direct tributaries and five are sub-tributaries. These include seven creeks and four runs. The largest tributary by both length and watershed area is Schwaben Creek, which is 10.7 miles (17.2 km) long and drains an area of 30.2 square miles (78 km2). The second-largest by these measures is Zerbe Run, which is 8.3 miles (13.4 km) long and drains an area of 13.1 square miles (34 km2). Many of the tributaries of Mahanoy Creek have been impacted by mining, including Zerbe Run, Shenandoah Creek, and North Mahanoy Creek. Schwaben Creek and Little Mahanoy Creek are the only large tributaries that are not affected by mining. Many of the upper tributaries are in the Western Middle Anthracite Field. In March 2001, the pH ranged from 4.7 for Lost Creek to 8.4 for Schwaben Creek. Some streams were downstream of abandoned mine drainage discharges accounting for their acidity. (Full list...)
