The Rapid City flood of June 9, 1972, which resulted in the loss of 238 lives, created medical problems stemming more from destruction of facilities than from overloading with serious casualties. Important lessons learned, or relearned, were the vital role of a central medical information center, the necessity of treating almost all wounds open, and the need for periodic practice drills for disaster plans. One of these had been held four days before the flood.
