Mahoning Creek is a tributary of the Susquehanna River in Columbia County and Montour County, in Pennsylvania, in the United States. It is approximately long and flows through Madison Township in Columbia County and West Hemlock Township, Derry Township, Valley Township, Mahoning Township, and Danville in Montour County. The watershed of the creek has an area of . Its tributaries include Kase Run, Mauses Creek, and Sechler Run. Mahoning Creek is designated as a Trout-Stocking Fishery and a Migratory Fishery for part of its length and as a Warmwater Fishery and a Migratory Fishery for the remainder. Mahoning Creek is considered by the Pennsylvania Department of Environmental Protection to be impaired by siltation. The main rock formations in the watershed include the Trimmers Rock Formation, the Clinton Group, the Catskill Formation, the Hamilton Group, the Bloomsburg and Mifflintown Formation, the Onondaga and Old Port Formation, and the Wills Creek Formation. The main soils include the Berks-Weikert-Alvira series, the Chenango-Pope-Holly series, the Clymer-Buchanan-Norwich series, and the Leck Kill-Meckesville-Calvin series. Most of the watershed is forested or agricultural land, but there is some developed land. There was historically a village of the Delaware tribe near the mouth of Mahoning Creek. The first people of European descent arrived in the area in the 1760s and 1770s. Various mills were constructed on it in the 1700s and 1800s. Numerous bridges have also been constructed across the creek. Part of the creek is in the Montour Ridge Landscape Corridor. == Course == Mahoning Creek begins in a valley in Madison Township, Columbia County. It flows south for a short distance before turning west-southwest for several tenths of a mile, exiting Columbia County.〔 Upon exiting Columbia County, Mahoning Creek enters West Hemlock Township, Montour County. It flows south-southwest alongside Pennsylvania Route 642 for a few miles before crossing Pennsylvania Route 642 and entering Derry Township. The creek then turns south for a few miles and enters Valley Township. In Valley Township, it continues flowing south in its valley and crosses Pennsylvania Route 642 before continuing south. The creek eventually enters a much broader valley and flows away from Pennsylvania Route 642. After several tenths of a mile, it crosses Interstate 80 and receives Kase Run, its first named tributary, from the left. The creek then meanders west for several tenths of a mile and then turns southwest, flowing alongside Pennsylvania Route 642 again. Not far from Mausdale, Mahoning Creek crosses Pennsylvania Route 642 and Pennsylvania Route 54 and receives the tributary Mauses Creek from the right. The creek then turns southeast and begins flowing alongside Pennsylvania Route 54 into Mahoning Township and through a water gap in Montour Ridge. It enters Danville and leaves behind the water gap, turning south-southwest and crossing US Route 11. After a few tenths of a mile, the creek receives Sechler Run, its last named tributary, from the left, and turns west-northwest. After several tenths of a mile, it exits Danville and enters Mahoning Township briefly before turning sharply southeast and reentering Danville. After a short distance, the creek reaches its confluence with the Susquehanna River.〔 Mahoning Creek joins the Susquehanna River upstream of its mouth. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mahoning Creek (Susquehanna River)」の詳細全文を読む スポンサード リンク
