Fall River County

Fall River County covers an area of rolling terrain in southwestern South Dakota with forested regions and protected natural areas scattered throughout. The landscape is defined by hills and mountainous sections, with the Black Hills National Forest occupying a significant portion of the county.

The county was established in 1883 and takes its name from the Fall River, a waterway that played a key role in early settlement. The founding occurred during a period of regional expansion and development in the area.

Hot Springs, the county seat, functions as the gathering place where residents and visitors encounter the region's local character and community life. The town reflects the heritage of the area through its buildings and the way people use the main streets.

Administrative services are available in Hot Springs during weekday business hours at the county office location. The area is best explored during spring through fall when weather conditions are favorable and outdoor activities are most enjoyable.

The Angostura Reservoir is an artificial lake that offers fishing and boating opportunities while serving as a wildlife management area. Visitors often discover that this water body provides unexpected recreation options in the midst of the surrounding hillside landscape.
