The Watershed Boundary Dataset (WBD) from The National Map (TNM) defines the perimeter of drainage areas formed by the terrain and other landscape characteristics. The drainage areas are nested within each other so that a large drainage area, such as the Upper Mississippi River, will be composed of multiple smaller drainage areas, such as the Wisconsin River. Each of these smaller areas can further be subdivided into smaller and smaller drainage areas. The WBD uses six different levels in this hierarchy, with the smallest averaging about 30,000 acres. The WBD is made up of polygons nested into six levels of data respectively defined by Regions, Subregions, Basins, Subbasins, Watersheds, and Subwatersheds. For additional...

The USGS National Hydrography Dataset (NHD) service from The National Map (TNM) is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information can be related to the NHD, and the direction of water flow. The network of reach codes delineating water and...

U.S. Geological Survey, Department of the Interior - The annual Watershed Boundary Dataset (WBD) stewardship plan is to maintain watershed boundary data through usage of WBD edit tools over the United States and its territories. WBD for the nation has been collected and is now in maintenance mode. Interested parties who wish to become a stewardship partner with the USGS in FY15 or in future years should contact a USGS Geospatial Liaison - http://liaisons.usgs.gov/geospatial/documents/TNM_Partnership_User_ContactList.pdf. To find out more about watershed boundary stewardship go to http://nhd.usgs.gov/wbd.html or http://nhd.usgs.gov/WBDstewardshipInfoSheet.pdf

This geodatabase contains streams, waterbodies and wetlands, streamflow gaging stations, and coastlines for the United States, Puerto Rico, and the U.S. Virgin Islands. The streams are incorporated into a geometric network. All feature classes are vertically integrated with each other and with 1:1,000,000-scale transportation and boundary data sets.
