The U.S. Government Moorings is located on the west bank of the Willamette River at river mile 6.2, within an area identified by the U.S. Environmental Protection Agency as a Superfund site under the Comprehensive Environmental Response, Compensation, and Liability Act.
The Corps began using the site in 1903 for centralized maintenance and as a supply facility. The Moorings currently provides port, supply and repair facilities for the Portland District’s fleet of dredges, hydrosurvey vessels and other support vessels.
