Flood control infrastructure often blocks fish from moving between rivers and oceans to streams and wetlands they seek for food, refuge, and rest. In some cases, they can even kill or severely injure fish. 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.
