The Johnstown Flood (Ep13)

On May 31, 1889, after torrential rains worse than any in recorded history, the South Fork Dam on the western side of the Allegheny Mountains broke, and 20 million tons of water poured downstream. Towns in its wake were leveled: South Fork, Mineral Point, Woodvale, East Conemaugh and, most notably, Johnstown. Prior to the September 11th attack on the World Trade Center, it was the deadliest man-made disaster in U.S. history. 2,209 people were killed. Johnstown and several neighboring towns were destroyed. This episode addresses the questions of why it happened and what happened afterward.
