Iroquois County, Illinois

Iroquois County sits at the eastern edge of Illinois, right up against the Indiana border. Common crops include corn and soybeans. The Iroquois River winds its way through the county, giving the area its name.

Watseka is the county seat and a small town with a lot of history. Folks here are proud of their agricultural roots. Some days, you’ll see more tractors than cars.

The county has its share of small towns, each with its own personality. Summers are hot and humid, perfect for growing crops. Winters bring icy winds whipping across the open fields. But the people weather it all with a smile.
