Lake Monona is a freshwater drainage lake in Dane County, Wisconsin surrounded on three sides by the city of Madison, Wisconsin and on the south side by the city of Monona, Wisconsin. It is the second-largest of a chain of four lakes along the Yahara River (also including Mendota, Kegonsa, and Waubesa) in the area and forms the south shore of the isthmus that forms downtown Madison. The name 'Monona' is a Chippewa word believed to mean 'beautiful', although the lake was originally named by the Ho-Chunk (Winnebago) 'Tchee-ho-bo-kee-xa-te-la' or 'Teepee Lake'.
