Waterway Network

Waterway Network This National Geospatial Data Asset (NGDA) dataset, shared as a United States Army Corps of Engineers (USACE) feature layer, displays national navigable waterway routes. Per USACE, “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.” St Croix River Data currency: Current federal service (Waterway Network) NGDAID: 153 (Navigable Waterway Routes (National) - National Geospatial Data Asset (NGDA) Waterway Lines) For more information, please visit: Definition of Navigable Waters of the US Support documentation: Navigable Waterway Network Lines For feedback, please contact: [e-mail] NGDA Theme Community This data set is part of the NGDA Transportation Theme Community. Per the Federal Geospatial Data Committee (FGDC), Transportation is defined as the "means and aids for conveying persons and/or goods. The transportation system includes both physical and non-physical components related to all modes of travel that allow the movement of goods and people between locations".
