What the National Weather Service wrote

Battle Creek flooded US Highway 85 north of Belle Fourche. A vehicle was swept away by the flowing water; one person had minor injuries but walked to the highway, the other was not found and is presumed dead.

The wider storm

An area of low pressure over northeastern Wyoming interacted with a stationary boundary across western South Dakota and produced slow moving thunderstorms. With ample low level moisture over the area, the thunderstorms produced torrential rainfall. Between three and six inches of rain fell across portions of Harding and northwestern Butte Counties on June 17. The runoff from these storms and additional rain on June 18 and 19 caused significant flooding across much of northwestern South Dakota.

Began near Castle Rock (45.0350, -103.5700).
