South Fork Dam
Former dam in Pennsylvania / From Wikipedia, the free encyclopedia
For the structure in Nevada, see South Fork Dam (Nevada).
The South Fork Dam was an earthenwork dam forming Lake Conemaugh (formerly Western Reservoir, also known as the Old Reservoir and Three Mile Dam, a misnomer),[1] an artificial body of water near South Fork, Pennsylvania, United States. On May 31, 1889, the South Fork Dam failed catastrophically and 20 million tons of water from Lake Conemaugh burst through and raced 14 miles (23 km) downstream, causing the Johnstown Flood.[2]
