Floods

A flood is caused by excess water surpassing the limits of its confines. A flood can happen during a myriad of events, including heavy rainfall and overflowing river banks. Floods present a significant danger with enough force to sweet away massive objects such as cars and trees.

Effects of Floods:

• Saint Francis Dam - March 12, 1928:

" In 1928, the Saint Francis Dam in Los Angeles was filled with 12.5 billion gallons of water - enough water for one year for a population of 1.2 million people. However, on March 12, 1928, the dam broke, unleashing a 78 foot wall of water. It obliterated houses, ranches, automobiles, animals, and people. In roughly one hour, more than 500 people were killed and Santa Paula was overrun by water."

• Grand Forks Flood - April 18, 1997

" On Friday, April 18, 1997, the Red River flooded over the dikes into Grand Forks, North Dakota. At the end of Saturday, the19th, the flood waters had spread over a large area of Grand Forks and East Grand Forks. Roughly 60,000 people were forced from their homes and downtown Grand Forks was left in flames. The damage was so extensive that it was weeks before people could return and rebuild their homes - and their lives."
