What is flood?
Flood is the presence of water on land that is normally dry. Flooding is a natural process that has shaped the earth’s landscapes and ecosystems for many thousands of years. When people develop floodplains for settlement, infrastructure, agriculture and other industries, flooding can cause adverse impacts.

Floods on The Fraser
The Fraser Valley and other parts of the Fraser Basin have experienced two major floods of written record, the largest in 1894 and the second largest in 1948.
How Would a Lower Mainland Flood Impact Us?
A large flood in the Lower Mainland may displace up to 300,000 people if there were multiple failures in diking systems. And disruptions would extend to those living outside the floodplain too. That’s because extensive flooding would impact transportation corridors, shipping routes and other critical infrastructure, and would disrupt social, cultural and economic activity. Look at the projected impacts.
