The National Waterway Network (NWN) is a geographic database of navigable waterways and channels in and around the United States, for analytical studies of navigation performance, for compiling commodity flow statistics, and for mapping purposes. The NWN is comprised of a link database and a node database. Links are line strings, which consist of beginning and end points (nodes) with intermediate vertices (shape points). Links represent either actual shipping lanes (i.e., channels, Intracoastal Waterways, sea lanes, rivers) or serve as representative paths in open water (where no defined shipping paths exist). Nodes may represent physical entities such as river confluence's, ports/facilities, and intermodal terminals, USACE nodes, or may be inserted for analytical purposes (i.e., to facilitate routing).

The National Waterway Network was created on behalf of the Bureau of Transportation Statistics, the U.S. Army Corps of Engineers, the U.S. Bureau of Census, and the U.S. Coast Guard by Vanderbilt University and Oak Ridge National Laboratory. Additional agencies with input into network development include Volpe National Transportation Systems Center, Maritime Administration, Military Traffic Management Command, Tennessee Valley Authority, U.S. Environmental Protection Agency, and the Federal Railroad Administration. data is continually being updated Navigation and Civil Works Decision Support Center United States Army Corp of Engineers (USACE) CEIWR-NDCWCSC WEBMASTER IWR 7701 Telegraph Road Alexandria VA 22315 United States web.CEIWR-NDCWCSCWEBMASTER@usace.army.mil party who can be contacted for acquiring knowledge about or acquisition of the resource data is updated as deemed necessary NTAD National Transportation Atlas Database National Transportation Atlas Database vector point Marine Maritime Inland Water Waterway Navigable Nodes inland waters oceans geospatial keyword identifies a particular subject or topic none NGDA National Geospatial Data Asset Transportation Theme NGDAID154 keyword identifies a particular subject or topic NGDA Portfolio Themes USA National keyword identifies a location none Nodes may represent physical entities such as river confluences, ports/facilities, and intermodal terminals, US Army Corps of Engineers (USACE nodes), or may be inserted for analytical purposes.Approximately 224 USACE ports are geo-coded in the node database. limitation not listed Access Constraints: unrestricted National Transportation Atlas Database 2025-09-30 publication Bureau of Transportation Statistics (BTS) party who published the resource reference to a master dataset of which this one is a part vector data is used to represent geographic data 100000 eng; USA transportation Native Dataset Environment: Version 6.2 (Build 9200) ; Esri ArcGIS 10.8.1.14362 -179.312134803331 179.135177854289 -53.0000201812036 72.1997322374615 2025-09-30 1 National Waterway Network Nodes A data dictionary resource of attribute information is accessible at https://doi.org/10.21949/1529054 Open Data Catalog 1.0 ArcGIS REST Services Directory Feature Server (WFS) 11.5 Bureau of Transportation Statistics (BTS) NTAD Program Manager 1200 New Jersey Ave. SE Washington DC 20590 United States ntad@dot.gov party who distributes the resource None.
