The Johnstown Flood occurred on May 31, 1889, after the catastrophic failure of the South Fork Dam on the Little Conemaugh River 14mi upstream of the town of Johnstown, Pennsylvania. The dam broke after several days of extremely heavy rainfall, releasing 14.55 million cubic meters of water from the reservoir known as Lake Conemaugh. With a volumetric flow rate that temporarily equaled the average flow rate of the Mississippi River, 2,209 people, according to one account, lost their lives, and the flood accounted for US$17 million of damage.The American Red Cross, led by Clara Barton and with 50 volunteers, undertook a major disaster relief effort. Support for victims came from all over the United States and 18 foreign countries. After the flood, survivors suffered a series of legal defeats in their attempts to recover damages from the dam's owners. Public indignation at that failure prompted the development in American law changing a fault-based regime to strict liability.HistoryThe village of Johnstown was founded in 1800 by the Swiss immigrant Joseph Johns (anglicized from "Schantz") where the Stony Creek and Little Conemaugh rivers joined to form the Conemaugh River. It began to prosper with the building of the Pennsylvania Main Line Canal in 1836 and the construction in the 1850s of the Pennsylvania Railroad and the Cambria Iron Works. By 1889, Johnstown's industries had attracted numerous Welsh and German immigrants. With a population of 30,000, it was a growing industrial community known for the quality of its steel.
