  4. The Break • 6-10 inches fell in 24 hours in a storm which formed in Kansas and Nebraska. • Lake Conemaugh was coming close to cresting the dam. Elias Unger, president of the club, worked with John Parke and a team of men to unclog the spillway and even tried digging a second spillway. • At 3:10, the dam gave way…

  5. The Torrent’s Path The water traveled at 22 feet per second. When it hit the viaduct, it reached a height of 76 feet. When it hit Johnstown, it was a wall of water 23 feet high. South Fork Casualties: 4 Mineral Point Casualties: 16 East Conemaugh Casualties: 50

  6. Johnstown! • About an hour after the break in the dam, • the water reached Johnstown. • As it hit the Cambria Iron works in Woodvale, • the boilers exploded. 314 Woodvale residents • died. • The flood would go on to kill a further 800 • people, bringing the Death toll to around 2,200. • 750 are buried in Johnstown’s unknown plot.

  7. Fire and Water 80 people were killed in the inferno. Debris stretched out for nearly 23 acres.

  8. Aftermath Nearly $17 million in damages were caused by a flood. Millions of dollars in relief funds poured in from across the country. Members of the South Forks Fishing and Hunting Club escaped legal responsibilities. The tragedy was declared an Act of God.
