Day County is a rural county in northeastern South Dakota. The county seat is Webster, and the area is one of many agricultural and conservation landscapes found across the state. According to the 2010 census, about 5,710 people lived in Day County. The county is discussed frequently in regional planning and conservation materials covering the county and in state overviews of the United States Great Plains.

Geography and natural features

Day County lies within the Prairie Pothole Region, a landscape of numerous shallow lakes and wetlands formed by glacial action. This patchwork of water and grassland supports waterfowl and other wildlife, and it has shaped local land use for generations. Several managed wetlands and refuges in and near the county provide habitat and recreational opportunities for birdwatching, hunting and fishing.

History and settlement

The area that became Day County was long used by Indigenous peoples of the Northern Plains, most notably groups of the Sioux (Lakota and Dakota) nations. Euro-American settlement accelerated in the late 19th century; the county was organized in the years that followed as rail lines and agricultural settlement expanded. Day County is named for Merritt H. Day, an early settler and local leader who was active in the region's development.

Economy, land use and recreation

Agriculture is the dominant economic activity in Day County: family farms and ranches raise crops such as corn, soybeans and small grains, and support livestock production. Conservation and outdoor recreation also contribute to the local economy. Hunters, anglers and birdwatchers visit wetlands and public refuges, and small businesses in towns like Webster provide services and supplies to area residents and visitors.

Like many rural counties in the Upper Midwest, Day County faces demographic change and economic challenges tied to farm consolidation and population shifts. At the same time, its natural wetlands and community institutions remain important to regional identity and to visitors seeking outdoor recreation and quiet small-town life.
