The Watervliet arsenal complex originally was built to house and manufacture weapons for the War of 1812. During the Civil War, it specialized in gun cartridges and artillery carriages. The facility today is a primary site for making state-of-the-art tank cannon, howitzers, mortars, and recoilless rifles.

The Bonneville Dam, Columbia River Power and Navigation System consists of 55 major projects on Oregon's Columbia River and is said to be the largest hydroelectric system in the world.

The Columbia River forms part of the border between Washington and Oregon and flows inland through the only waterway that crosses the Cascade Mountains. To harness the energy of the ninth longest river in North America, engineers developed unique design and construction approaches to overcome problems caused by depth of water, current velocity, and an irregularly-shaped river bottom.
