Big Wapwallopen Creek (also known as Wapwallopen Creek or Big Wap) is a tributary of the Susquehanna River in Luzerne County, Pennsylvania, in the United States. It is approximately long and flows through Bear Creek Township, Fairview Township, Rice Township, Wright Township, Dorrance Township, Hollenback Township, Nescopeck Township, and Conyngham Township. The watershed of the creek has an area of . The creek has three named tributaries: Balliet Run, Watering Run, and Bow Creek. The creek is designated as a Coldwater Fishery and a Migratory Fishery and is also Class A Wild Trout Waters for part of its length. However, it is considered to be impaired by organic enrichment and/or low levels of dissolved oxygen and its pH ranges from moderately acidic to slightly alkaline. Big Wapwallopen Creek has three large waterfalls, all of which are more than high. The creek flows through the Wapwallopen Gorge in its lower reaches, where it descends . It mainly flows through rock formations consisting of sandstone and shale. The creek has existed for several million years, but the portion of its course that flows through the Wapwallopen Gorge is less than 20,000 years old. The creek's watershed is mainly rural and most of it is forested. It is the main source of flooding in six townships.〔 Wapwallopen Creek is named after a Native American village that historically existed on the creek. The Delaware tribe inhabited the area by 1675 and the Shawnee tribe also historically inhabited the area. Numerous mills were built on the creek in the 1700s and 1800s, including two powder mills in the Wapwallopen Gorge. The second powder mill was built in 1859 by E.I. Du Pont de Nemours and Company and was one of the largest powder mills in the United States at the time. That powder mill operated until 1912. Numerous bridges were built across the creek in the 1900s. The Wapwallopen Gorge is listed on the Luzerne County Natural Areas Inventory. It is possible to canoe on of the creek, but there are some unrunnable points. ==Course== Big Wapwallopen Creek begins in Crystal Lake in Bear Creek Township. It flows west for several tenths of a mile and enters Fairview Township. The creek turns west-southwest for approximately a mile, passing Arbutus Peak to the south and crossing Pennsylvania Route 437. It then turns west-northwest for several tenths of a mile before turning southwest and then west, crossing Pennsylvania Route 309. It passes through Pole Bridge Swamp and begins flowing along the border between Rice Township and Wright Township. Over the next couple of miles, the creek gradually turns south-southwest, still following the township line. It then passes through Hickory Swale and receives Bow Creek, its first named tributary, from the left. It turns southwest for several tenths of a mile before turning south and then southwest. It then turns west for more than a mile before turning southwest for a few miles, receiving the tributary Watering Run from the left before entering Dorrance Township and crossing Interstate 81. The creek then turns south for a few tenths of a mile before turning west and then southwest for a few miles, passing Feys Grove. It eventually tuns west-southwest and enters Hollenback Township. After a few miles, the creek turns south for a short distance and receives Balliet Run, its last named tributary, from the left. It then turns west-northwest for more than a mile before turning south. At this point, the creek turns west again and enters a gorge. After several tenths of a mile, it turns north again, still flowing through the gorge and crossing the border between Hollenback Township and Nescopeck Township several times. The creek then turns west-northwest and begins flowing along the border between Nescopeck Township and Conyngham Township. After approximately a mile, it leaves the gorge and crosses Pennsylvania Route 239. It then reaches its confluence with the Susquehanna River just southwest of Wapwallopen.〔 Big Wapwallopen Creek joins the Susquehanna River upriver 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「Big Wapwallopen Creek」の詳細全文を読む スポンサード リンク
