The Johnstown Flood (locally, the Great Flood of 1889) occurred on May 31, 1889, after the catastrophic failure of the South Fork Dam on the Little Conemaugh River 14 miles (23 km) upstream of the town of Johnstown, Pennsylvania. The dam broke after several days of extremely heavy rainfall, releasing 14.55 million cubic meters of waterWith a volumetric flow rate that temporarily equaled the average flow rate of the Mississippi River,[5] the flood killed more than 2,200 people[6] and accounted for $17 million of damage (about $474 million in 2018 dollars[3]).
The total death toll was calculated originally as 2,209 people,[1] making the disaster the largest loss of civilian life in the United States at the time. This number of deaths was later surpassed by fatalities in the 1900 Galveston hurricane and the September 11, 2001 terrorist attacks.
