Peterman Run is a tributary of West Branch Fishing Creek in Sullivan County and Columbia County, in Pennsylvania, in the United States. It is approximately 1.7miles long and flows through Davidson Township in Sullivan County and Sugarloaf Township in Columbia County. The watershed of the stream has an area of 0.41sqmi. Glacial till and bedrock consisting of shale and sandstone can be found along the stream. It is considered to be impaired by atmospheric deposition and metals.
Peterman Run begins on a plateau in Davidson Township, Sullivan County. It flows south-southwest for a few tenths of a mile before leaving the plateau and flowing down its side, descending steeply. The stream continues flowing south-southwest. After several tenths of a mile, it exits Sullivan County.
Upon exiting Sullivan County, Peterman Run enters Sugarloaf Township, Columbia County. It turns south for a short distance before reaching the bottom of the slope and turning east. After several hundred feet, the stream turns south-southeast. After approximately a thousand feet (three hundred meters), it reaches its confluence with West Branch Fishing Creek.
Peterman Run joins West Branch Fishing Creek 2.88miles upstream of its mouth, only 0.06miles upstream of the mouth of Rough Run.
A total of 1.63miles of Peterman Run is considered to be impaired due to atmospheric deposition and metals. The impaired waters of the stream comprise approximately 4.01 percent of the total impaired waters in Sullivan County within the watersheds of West Branch Fishing Creek and East Branch Fishing Creek.
The elevation near the mouth of Peterman Run is 1115feet above sea level. The elevation of the stream's source is between 2240feetand2260feetft (andft) above sea level.
A significant portion of the lower reaches of Peterman Run is on a glacial till known as the Wisconsinan Bouldery Till. The surface is largely covered with boulders and it is a diamict. The Wisconsinan Bouldery Till is typically at least 6feet thick. Alluvial terrace also occurs near the stream's lower reaches, in the valley of West Branch Fishing Creek. The Wisconsinan Till occurs near the stream's headwaters and is typically more than 6feet thick. Bedrock consisting of sandstone and shale can be found in the stream's middle reaches.
The watershed of Peterman Run has an area of 0.41sqmi. The stream is entirely within the United States Geological Survey quadrangle of Elk Grove. The stream's watershed is part of the Upper Susquehanna-Lackawanna drainage basin.
Peterman Run is in the vicinity of Pennsylvania State Game Lands Number 13.
Peterman Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1183619.
Peterman Run was listed as impaired in both 2002 and 2004.
