About Seattle District

The boundaries include the Columbia River system upstream of the mouth of the Yakima River, much of eastern Washington, Northern Idaho and western Montana to the Continental Divide. Seattle District’s regulatory jurisdiction covers the entire state of Washington.

Seattle District oversees more than 10,000 acres of public land and water. Seattle District operates five dams: Libby, Albeni Falls, Chief Joseph, Hiram M. Chittenden Locks, Howard Hanson and Mud Mountain dams. Our public lands, including the Chittenden Locks in Seattle and campgrounds on Lake Pend Oreille in Idaho, host more than 2 million visitors a year.

The district provides assistance in flood fighting, rehabilitation of flood control works damaged or destroyed by floods, and advance measures prior to floods. The district has responded to earthquakes, bombings, hurricanes and other emergencies. Also, the district, upon request, provides both technical advice and direct assistance to the Federal Emergency Management Agency under the National Response Framework.

In addition, the district supports the Environmental Protection Agency with a number of cleanups around the Northwest.

The District conducts work for other federal, state, local and tribal agencies, similar to military or civil works projects. Facilities design and construction and environmental cleanup work are common projects.
