National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed August 15, 2011〕 tributary of the Tygart Valley River in north-central West Virginia, USA. Via the Tygart Valley, Monongahela and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of on the unglaciated portion of the Allegheny Plateau. It provides drinking water for much of Upshur County. ==Geography== The Buckhannon River is formed at the community of Alexander in southern Upshur County by the confluence of the Left Fork Buckhannon River〔 and the Right Fork Buckhannon River, both of which rise in southwestern Randolph County at elevations of and , respectively,〔Google Earth elevations for GNIS source coordinates.

The Right Fork flows through the communities of Pickens and Selbyville and collects tributaries known as the Middle Fork Right Fork Buckhannon River and the Left Fork Right Fork Buckhannon River; the Left Fork of the Right Fork flows through the community of Helvetia.〔DeLorme (1997). ''West Virginia Atlas & Gazetteer''. Yarmouth, Maine: DeLorme. ISBN 0-89933-246-3.〕 From Alexander the Buckhannon River flows generally northwardly, past Sago, to the city of Buckhannon, then northeastwardly into southwestern Barbour County, past Boulder (Rangoon Post Office) and Carrollton, where it is crossed by the Carrollton Covered Bridge. It joins the Tygart Valley River just downstream of Carrollton, approximately southwest of Philippi.〔 According to the West Virginia Department of Environmental Protection, approximately 79.5% of the Buckhannon River's watershed is forested, mostly deciduous; approximately 18.1% is used for agriculture and pasture; and less than 1% is urban.〔 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「Buckhannon River」の詳細全文を読む スポンサード リンク
