Description: The Commercially Navigable Waterways (CNW) data is a subset of the National Waterway Network (NWN) as distributed by the US Army Corps of Engineers (available for download at https://www.iwr.usace.army.mil/About/Technical-Centers/NDC-Navigation-and-Civil-Works-Decision-Support/; for purposes of this data preparation NPMS used data available from the Bureau of Transportation Statistics (BTS) at https://data-usdot.opendata.arcgis.com/datasets/navigable-waterway-network-lines/explore). Lines in the NWN with a FUNC_CLASS attribute value equal to S, B, or D were extracted from the NWN and are considered by PHMSA to be commercially navigable. The data set covers the 48 contiguous states plus the District of Columbia, Hawaii, Alaska, Puerto Rico and water links between. The nominal scale of the dataset varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters.
The Commercially Navigable Waterways (CNW) dataset was derived from the National Waterway Network (NWN). The NWN databases were developed by Oak Ridge National Laboratory (ORNL) and Vanderbilt University, with input from the National Waterway GIS Design Committee (NWGISDC). The NWGISDC contains members from several agencies, including the U.S. Army Corps of Engineers (USACE), USDOT Bureau of Transportation Statistics (BTS), Volpe National Transportation Systems Center (VNTSC), Maritime Administration (MARAD), Military Traffic Management Command (MTMC), Tennessee Valley Authority (TVA), U.S. Environmental Protection Agency (EPA), U.S. Bureau of Census, U.S. Coast Guard, and the Federal Railroad Administration (FRA).
