Walworth County, located in southeastern Wisconsin, is one of the oldest and wealthiest counties in the state. The diversified topography has rolling hills, forests, prairies, marshes, meadows, and winding streams. It is a perfect square in shape, containing 576 square miles (368,640 acres). There are 24 lakes, the largest being Geneva Lake which is nine miles long, from one to three miles wide, with water supplied by fresh springs.
Walworth County was first organized in 1838 when Milwaukee county was subdivided. It was named after judge Rueben H. Walworth, chancellor of New York state. The first election of officers was in the fall of 1838 and in December of 1839, Elkhorn was made the county seat. Shortly after, the first county board was formed. The first courthouse was built in 1839 by Rockwell in the north part of Elkhorn.
