Overview

Late in the afternoon on May 18, 2018, a localized thunderstorm moved over Rapid City and dumped two to three inches of rain in about an hour. Runoff from the heavy rainfall flooded streets and low-lying areas. Rapid Creek quickly rose and overflowed its banks near the Fairgrounds. In Rapid City, several water rescues were performed by the fire department. The heaviest rainfall fell over the Robbinsdale area, where the runoff filled a detention pond near the park and tore up sections of asphalt on Fairlane Drive. Several vehicles were pushed by the rushing water and one vehicle ended up in the Robbinsdale Park detention pond.
