2026: Understanding Current and Future Skagit Flooding Risk Modeling Capabilities Project

Swinomish Indian Tribal Community, Skagit Climate Science Consortium, Skagit River Cooperative, University of Washington Climate Impacts Group, Northwest Hydraulics Consultants, United States Army Corps of Engineers

Designed to build upon the best available science to create an updated, climate-informed model of flooding in the Skagit watershed, this project includes a modernized hydraulic model with comprehensive maps, animations and numerous resources to increase shared understanding of Skagit flooding now and in the future.
