Geneva Lake (Wisconsin)

Geneva Lake is a natural lake in Walworth County in the southeastern portion of the U.S. state of Wisconsin.

On its shores are the city of Lake Geneva and the villages of Fontana-on-Geneva-Lake and Williams Bay.

The lake covers an area of approximately 5,401 acres (2,186 ha; 8.439 sq mi; 21.86 km2), with a maximum length of 7.7 miles (12.4 km), a mean depth of 61 feet (19 m), and a maximum depth of 135 feet (41 m). Geologists believe that it is a filled-in kettle formed from a receding glacier.
