Washington’s Green-Duwamish River provides important habitat for chinook salmon — vital to local tribes and communities and critical to the diet of endangered southern resident killer whales (orcas). However, decades of contamination, floodplain development and dams have devastated the salmon population. Further, current flood management is inadequate to protect local communities from increasing flood risks due to climate change. As the King County Flood Control District develops the Lower Green River Corridor Flood Hazard Management Plan, it must select community supported alternatives for the plan that will promote sustainable flood management and significantly increase salmon habitat.
