The Johnstown Floo disaster (or Great Flood of 1889 as it became known locally) occurred on May 31, 1889. It was the result of the failure of the South Fork Dam situated 14 miles (23 km) upstream of the town of Johnstown, Pennsylvania, USA, made worse by several days of extremely heavy rainfall. The dam's failure unleashed a torrent of 20 million tons of water (18.1 million cubic meters/ 4.8 billion U.S. gallons). The flood killed over 2,200 people and caused US$17 million of damage. It was the first major disaster relief effort handled by the new American Red Cross, led by Clara Barton. Support for victims came from all over the United States and 18 foreign countries.
