Much of the flood control infrastructure in the Lower Mainland is aging and outdated, leaving communities at risk of flooding. It also often blocks fish from moving between rivers and oceans to streams and wetlands they seek for food, refuge, and rest. In the lower mainland its estimated that over 1500 km of salmon habitat is blocked by 156 pieces of flood control infrastructure.
However, there are increasingly more examples of flood control infrastructure that are friendlier to fish than others. Check out our explainer animation videos created in collaboration with Watershed Watch Salmon Society below to learn more about the good, the bad, and the ugly of flood control infrastructure.
