Walworth County, Wisconsin. Located in the southeastern part of the state, it is a prominent component of the Chicago metropolitan area and part of the Lake Geneva region. The county is known for its numerous glacial lakes, including Geneva Lake, which drive a significant tourism and recreation economy. Its county seat is Elkhorn, while its most populous city is Whitewater, home to the University of Wisconsin–Whitewater.

History

The region was originally inhabited by the Potawatomi and other Algonquian peoples before European American settlement accelerated following the Black Hawk War of 1832. Walworth County was created by the Wisconsin Territorial Legislature in 1836 and organized in 1839, named for Reuben H. Walworth, the last Chancellor of New York. Early development was spurred by settlers from New England and New York, with the first county seat at Spring Prairie before moving permanently to Elkhorn. The arrival of the Chicago and North Western Railway in the 1850s connected the area to Milwaukee and Chicago, transforming communities like Lake Geneva into popular resorts for wealthy industrialists from those cities. Notable historical events include the Walworth County Fair, established in 1849, one of the oldest continuous county fairs in Wisconsin.

Geography

According to the United States Census Bureau, the county has a total area of 577 square miles, of which 555 square miles is land and 22 square miles (3.8%) is water. Its terrain consists of rolling glacial hills and moraines, part of the Kettle Moraine region, dotted with over 100 lakes formed by retreating glaciers during the Wisconsin glaciation. Major bodies of water include Geneva Lake, Lake Como, and Delavan Lake, which feed into the Fox River and ultimately the Illinois River. The county borders Racine County to the east, Waukesha County to the northeast, Jefferson County to the north, Rock County to the west, and McHenry County and Boone County in Illinois to the south.
