The Portland District was established in 1871 and has one of the nation's most comprehensive and diversified civil works programs.

Covering most of Oregon and southwestern Washington, the District operates locks and dams along the Columbia River, operates dams in the Willamette Valley for flood risk management, maintains Oregon's coastal rivers for navigation and leads the Nation in hydropower generation, all while ensuring equal attention to environmental protection and restoration, fish and wildlife enhancement and recreation.

The Portland District is proud to host three Centers of Expertise: Hydroelectric Design Center, Roller Compacted Concrete, and Welding and Metallurgy. 


Military command of the District is made up of the District Commander and Deputy District Commander. The Portland District Commander also serves as the District Engineer. Civilian oversight for the District is provided by the Deputy District Engineer for Programs and Project Management.
