New NHDPlus HR Map Service

Release Date:

The USGS is pleased to announce the release of the NHDPlus High Resolution (NHDPlus_HR) map service. The NHDPlus_HR map service provides an easy way to browse NHDPlus HR data, including catchments, and access VAAs without having to download datasets.

The map service is a national seamless representation of NHDPlus HR vector data and selected NHDPlus HR Value Added Attributes (VAAs) at scales of 1:250K and larger. At this time, the NHDPlus_HR service includes coverage for most of the conterminous United

States (minus parts of the Great Lakes) and select areas of Alaska. 

Coverage is currently missing for these regions:

  • 04 - Great Lakes 
  • 1802, 1803, 1804, 1805 (California) 
  • 08 – Lower Mississippi 
  • 20 - Hawaii 
  • 21 - Caribbean 
  • 22 - South Pacific 

The NHDPlus_HR map service will be updated as improved NHDPlus HR staged products are available.  

 

Because the service is only active when zoomed in to a detailed level, it is suggested that it be used in conjunction with either a topographic base map or with the USGS Hydrography Tile Cache (https://basemap.nationalmap.gov/arcgis/rest/services/USGSHydroCached/MapServer) map service.  

 

The NHDPlus_HR map service is accessible as an Esri map service and Open Geospatial Consortium (OGC) Web Map Service (WMS) endpoints. For access to the map service and service endpoints, please visit The National Map Service Endpoints webpage, or the direct map service link:  https://hydro.nationalmap.gov/arcgis/rest/services/NHDPlus_HR/MapServer
