Dell Rapids is a small Minnehaha County city on the Big Sioux River northeast of Sioux Falls, with tornado exposure common to the eastern South Dakota plains and flooding risk from the Big Sioux River. The river has caused periodic flooding in the city during snowmelt and heavy rainfall events. Its position in the Sioux Falls metro fringe means it shares regional storm risk but has more limited local emergency response capacity.
