The river is also impacted by the Tukwila Dam, which can affect water levels and flow. Seasonal trends include higher flows in the winter and lower flows in the summer, due to precipitation patterns. Additionally, the hydrology of the Duwamish River is affected by the urbanization of the surrounding area, which can cause flash flooding during heavy rain events. An interesting fact is that the river was once a major source of seafood for the Duwamish tribe, but is now considered one of the most polluted waterways in the United States.
