It is about long.〔U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed June 20, 2011〕 In the 19th century it was an important commercial waterway, where building materials and other products of the North Shore of Lake Pontchartrain were loaded to be shipped across the Lake to New Orleans. ==Course== The Tchefuncte rises in northeastern Tangipahoa Parish and initially flows southward; the river is used to define part of the eastern boundary of Tangipahoa Parish and parts of the western boundaries of Washington and St. Tammany Parishes before turning southeastward into St. Tammany Parish, where it passes the city of Covington and the town of Madisonville. It collects its largest tributary, the Bogue Falaya, at Covington and flows into Lake Pontchartrain about south of Madisonville, near the lake's northern extremity. The Tchefuncte has been designated by the government of Louisiana as a "Natural and Scenic River." Fairview-Riverside State Park is located along the river, upstream of Madisonville. 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「Tchefuncte River」の詳細全文を読む スポンサード リンク
