From July 18th to 21st, 1996, a huge amount of rain fell in the Saguenay Lac-Saint-Jean region of Quebec.
Dams and dikes were overwhelmed and major flooding occurred. The storm produced the largest overland deluge of flooding that century, triggering a surge of water, rocks, trees and mud. 10 people were killed and about 12,000 residents were forced to flee their homes.
It was the first disaster in Canada where total losses were over one billion dollars.
