Sécurité publique Québec has ordered the evacuation of the lower Rouge River valley in response to an assessment that the Chute-Bell Hydro Québec dam may fail as high water levels continue to plague the region.

Hydro Québec has been posting regular updates about the situation, sharing that the dam had reached its maximum water level.
The company has also posted an impressive video that shows just how much water is pushing against the dam. Floodwater pours over its brink.
