The Johnstown Flood, otherwise known as the Great Flood of 1889, occurred in Pennsylvania on the 31st of May, 1889. 2209 people were killed when a dam broke and unleashed 20 million tons of water on the surrounding area.
The six people who were inside this house all survived. X
Heavy rain hit the area in the days before the flood, and despite attempts to save the dam before it broke, nothing could be done and everybody retreated to wait. The flood began at about 3:10pm.
The wave of water that hit surrounding towns was said to have reached 18 metres (60 feet) in height.
