Walworth County, South Dakota

Walworth County sits in north-central South Dakota, straddling the Missouri River. Selby serves as the county seat, but Mobridge is the biggest town.
It’s known as the “Walleye Capital of the World”. There’s a nice ring to it. Fishing is a way of life here in any of its lakes.
The county has a mix of prairie and river valley. Ranching is big business and so is tourism, thanks to the river. Community spirit runs deep in Walworth County.
