The U.S. Army Corps of Engineers is the federal government's largest water resources development and management agency. The Corps' purpose is to provide quality, responsive, cost effective engineering services to support the nation in peace and war. A broad range of professionals--engineers, biologists, natural resource managers, archaeologists and many more--make up the corps' work force.
The Corps' North Pacific Division, headquarters in Portland OR, is made up of four districts: Portland, Seattle, Walla Walla and Alaska. The corps constructs, operates and maintains nine dams on the Columbia and Snake River. The Corps also is responsible for dredging at coastal ports and on the Columbia and Willamette rivers.
The Corps is also a partner with other regional interests in all work to rebuild migratory fish runs in the Northwest.
