It flows for 〔U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed May 1, 2012〕 in Ashland County, draining an area of in portions of Ashland, Bayfield and Iron counties. The Bad River sloughs were designated a Ramsar Wetland of International Importance on February 2, 2012. ==Course== The Bad River issues from the southwestern end of Caroline Lake,〔DeLorme (1992). ''Wisconsin Atlas & Gazetteer''. Freeport, Maine: DeLorme. pp. 95, 103. ISBN 0-89933-247-1.〕 a shallow lake on the boundary of Ashland and Iron counties which drains an area of acidic peatlands to its east. The Bad River initially flows southwestwardly before turning generally to the north for most of its course, along which it passes through the city of Mellen, Copper Falls State Park, and the community of Odanah in the Bad River Indian Reservation.〔 In the vicinity of Mellen, the riverbed is commonly bedrock and boulder-strewn with numerous whitewater rapids; the river passes over waterfalls and through a granite gorge in Copper Falls State Park.〔 In its lower course in the Bad River Reservation the river's delta along Lake Superior contributes to a complex of wetlands known as sloughs. The Bad River's largest tributary is the White River,〔 which it collects near its mouth. Other principal tributaries include the Potato and Marengo rivers in its lower course; the Tyler Forks at Copper Falls State Park; and the Iron River upstream of Mellen.〔 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「Bad River (Wisconsin)」の詳細全文を読む スポンサード リンク
