gave way on this date in 1889 flooding Johnstown, Pennsylvania. The Johnstown Flood National Memorial (National Park Service) describes the event:
There was no larger news story in the latter nineteenth century after the assassination of Abraham Lincoln. The story of the Johnstown Flood has everything to interest the modern mind: a wealthy resort, an intense storm, an unfortunate failure of a dam, the destruction of a working class city, and an inspiring relief effort.
The rain continued as men worked tirelessly to prevent the old South Fork Dam from breaking. Elias Unger, the president of the South Fork Fishing and Hunting Club, was hoping that the people in Johnstown were heeding the telegraph warnings sent earlier, which said that the dam might go. When it finally happened, at 3:10 P.M., May 31, 1889, an era of the Conemaugh Valley’s history ended, and another era started. Over 2,209 people died on that tragic Friday, and thousands more were injured in one of the worst disasters in our Nation’s history.
