Johnstwon Flood 1977

 This flood was catastrophic because 130 million gallons of water flooded the streets of Pennsylvania. The waters carved their own paths through office buildings, factories and apartments. This happened because there were 12 inches of rain in 10 hours, and this means that there were storms back to back. This caused dams to overflow and eventually break. The people of Pennsylvania were extremely mad because the dams have daily checks and inspections and they all came black clean. After the flooding there was $300 million in damage and 84 deaths. This might've been avoided if the inspectors did a better job, but because 5 dams broke this led to better reinforcements on the bottom of the dams all around Pennsylvania. 100's of people were left homeless and they no longer had jobs. It took Pennsylvania years to get Cambria County back to its original state.
