Twomile Run
Twomile Run is a tributary of Kettle Creek in Clinton County, Pennsylvania, in the United States. It is long. Tributaries of the stream include Huling Branch and Middle Branch Twomile Run. The stream flows through Leidy Township and Noyes Township. The stream's watershed has an area of approximately 9 square miles. Coal is mined in the watershed. Most of the acid mine drainage in Kettle Creek comes from Twomile Run.
The discharge of Twomile Run at its mouth ranges from 200 to 10,000 gallons per minute. There are 2.1 to 11.7 milligrams per liter of manganese in the waters at this location. In 2007, the average pH at the mouth of the stream was 3.52, with a range of 3.4 to 3.9. By 2011, the stream's pH had increased slightly upstream of Huling Branch. Rock formations in the watershed include the Huntley Mountain Formation, the Burgoon Sandstone, the Allegheny Group, and the Pottsville Group.
==Course==
Twomile Run begins in Sproul State Forest in Leidy Township, Clinton County. The stream flows south and slightly east, leaving Sproul State Forest and Leidy Township and then entering Noyes Township. Soon after entering Noyes Township, it receives the tributary Middle Branch Twomle Run and continues south. The Twomile Run valley begins to get deeper at this point. The stream turns southwest, then southeast, and then southwest again. Shortly after the final bend, it receives the tributary Huling Branch and not long afterwards enters Kettle Creek.
