The Johnstown Flood Kills Over 2,200 People
On May 31, 1889, the South Fork Dam in Pennsylvania — poorly maintained by a wealthy Pittsburgh hunting and fishing club — collapsed after days of heavy rain, unleashing a wall of water estimated at sixty feet high and moving at forty miles per hour. The flood struck the city of Johnstown fourteen miles downstream within minutes, obliterating entire neighborhoods and killing more than 2,200 people in what became the deadliest civilian disaster in American history to that point. Survivors described a roaring that preceded the wave, leaving almost no time to flee. In the aftermath, houses, trees, locomotive engines, and the bodies of the dead were piled against a stone bridge and caught fire. The club's wealthy members — who had lowered the dam to accommodate carriage traffic — were never held legally responsible, provoking national outrage and early discussions of corporate liability. Clara Barton and her American Red Cross conducted their first major disaster relief operation at Johnstown.
