Forty days and forty nights…

"On that day, all the fountains of the great deep burst forth, and the windows of the heavens were opened.... The waters swelled so mightily that all the high mountains under heaven were covered... for 150 days." (Genesis).

Seven-thousand six-hundred years ago the Black Sea had been a freshwater lake hundreds of feet below the level of the Mediterranean Sea. Then, as the meltwater from the receding glaciers filled the world’s oceans, the rising seas flowed over the Bosporus Valley. Salt water flowed into the lake with catastrophic consequences to the area. The rising waters engulfed communities and people were forced from their ancestral homes. Noah, it appears, was the lucky owner of a boat.

As the waters subside and the clean up continues in Squamish and Pemberton, it is a good time to reflect on the recent flooding. Media has expounded significantly on the devastation caused by the flooding in Squamish and Pemberton, but so far has failed to highlight the importance of such events. In light of the recent floods, what can we learn from Noah and his merry band of animals?

First, floods are natural events. They are part of the global hydrologic cycle whereby water is continually cycled between the earth and the atmosphere. Just because we dike rivers and build communities, doesn’t mean Mother Nature will turn a blind eye.

Second, floods are a creative force. We depend on them. The fertility of the soils supporting agriculture in the Pemberton Valley is the result of infinite flooding events. Scientists believe that massive debris-flows and floods in Pemberton ~2,600, ~4,000, and ~6,200 years ago are responsible for sediment deposits up to 8 metres thick respectively.

Third, nature is resilient. Just like Noah and his animals, we will carry on after these big flood events. Floods are just one more component of the ecosystem we live in.

The recent high rainfall and flooding events as well as the fires throughout B.C. have had profound effects not just in our local communities but throughout the province as a whole. They will force us to re-think the management of our resources in light of further extreme climatic events associated with climate change. As we rebuild after the floods, it is a time of reflection. A time to reflect not just on the past, but on what we can do to ensure a sustainable future.
