Lake Winnebago is a freshwater lake in eastern Wisconsin, United States. It is the largest lake entirely within the state,〔(Lakes ), United States Department of the Interior, Retrieved September 21, 2008〕 covering an area of about , with of shoreline, an average depth of and a maximum depth of .〔 It has many shallow reefs along the west shore, and a drop-off type shoreline on the east.〔 There are several islands along the west shore. Lake Winnebago has two primary tributaries, the Wolf River and the Fox River. It is drained by the Fox River which flows north towards Green Bay and serves as part of the Fox-Wisconsin Waterway. Lake Winnebago is part of a larger system of lakes in Wisconsin known as the Winnebago Pool. Cities on its shores include Oshkosh, Fond du Lac, Neenah and Menasha. Municipal drinking water systems serving over 250,000 people draw directly from the lake, including systems serving the cities of Oshkosh, Neenah, Menasha and Appleton. ==History== The lake is a remnant of Glacial Lake Oshkosh approximately 12,000 years ago.〔(Lake Oshkosh Drainage ); Steven Dutch; Natural and Applied Sciences; University of Wisconsin–Green Bay; Last updated April 29, 2005; Retrieved January 14, 2007〕 Ice blocked water from entering Lake Michigan at Green Bay, and the glacial lake ponded against ice since it had no outlet. The Niagara Escarpment is a few miles east of Lake Winnebago. The softer Ordovician rocks that underlie the lake have eroded away, and the stronger Silurian rocks stand as a ridge that formed the lake basin.〔(The Niagara Escarpment ); Steven Dutch; Natural and Applied Sciences; University of Wisconsin–Green Bay; Last updated June 18, 1999; Retrieved January 14, 2007〕 In 1634, the French discovered the Winnebago Indian tribe on the shores of Green Bay, Wisconsin, inhabiting the area stretching to Lake Winnebago. Although "Ho-Chunk" is the people's own name for themselves, their Algonquian neighbors called them "Winnebago", which means "people of the filthy water". This term was used by the Algonquians because Lake Winnebago had a strong fish odor in the summer.〔William J. Kubiak (Great Lakes Indians) Grand Rapids: Baker Book House Company, 1970〕 The steamer B. F. Carter made a trip from the east shore to the west shore at Oshkosh every two weeks in the 1880s during the summer season. Lake Winnebago is known for having occasional ice shoves on very windy days in March as the winter ice breaks up.〔(【引用サイトリンク】url=http://www.wsaw.com/home/headlines/42256267.html )〕 Residents have described that it "sounds like a freight train." Buildings on the shore have been wrecked by the shoves, which are up to 25 feet high.〔〔 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「Lake Winnebago」の詳細全文を読む スポンサード リンク
