Flood Risk Management

Seattle District plans, designs, constructs, operates and maintains flood risk management projects, and provides flood plain management services. Mud Mountain Dam on the White River and Howard Hanson Dam on the Green River are two Corps flood risk management dams located in western Washington. Libby Dam on the Kootenai River in western Montana and Albeni Falls Dam on the Pend Oreille River in northern Idaho also provide flood risk management benefits.

Hydropower

The Seattle District operates and maintains three hydropower projects. Albeni Falls Dam, Libby Dam and Chief Joseph Dam on the Columbia River system produce 3,025 megawatts of electricity—more than enough to power a city the size of Seattle.
