Description:

Have a question? Ask the National Hydrography Support Team nhd@usgs.gov The USGS National Geospatial Program manages the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR). These geospatial datasets represent the surface water of the United States for mapping and modeling applications.Update National Hydrograpy with the Markup AppHave a correction or update for the NHD, WBD, or NHDPlus High Resolution?

These include the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR). Hydrography data are integral to a myriad of mission critical activities undertaken and managed by government entities (Federal, state, regional, county, local, Tribal), nonprofit organizations, and private companies. Hydrography data make it possible for these groups to, for example:Manage water such as stream flow and stormwaterMonitor, manage, and report water qualityAssess water availability and water rightsModel and map flood riskConserve terrestrial and aquatic habitatsManage fisheries, rangeland, timberlands, and agricultural landsAssess coastal hazardsPlan for future land development activities and infrastructure developmentManage riverine and coastal navigation and safetyProvide recreational opportunities for citizensPlease see the About National Hydrography Products link for more detailed information on national hydrography products. Accessing Hydrography ProductsDirect download links and web-based map service information are available from the Access National Hydrography Products page. Downloads via interactive map are available from The National Map Download viewer, and all web-based map services are listed at The National Map Service Endpoints page.Resources and ToolsMany resources and tools exist to support the National Hydrography Datasets. Tools include the Markup Application to suggest edits, or “markups”, to the NHD, WBD, and NHDPlus HR, as well as the Hydrologic Event Management (HEM) Tool to create, manage, and refresh of event data that is referenced to hydrography data. Tools are also available to stewards to edit and manage NHD and WBD data.A series of training videos on hydrography and other USGS geospatial data and products are also available.StewardshipNational Hydrography Datasets are updated and maintained through a strong community of stewards and users who have local knowledge about the streams where they live and work. Edits and updates to the NHD and WBD are made by stewards and processed and made available in the national dataset distribution by the USGS. For more information, please visit the Stewardship and Community link.GovernanceThe NHD and WBD are managed by the USGS under OMB Circular A-16 and as a part of the FGDC National Geospatial Data Asset (NGDA) Water-Inland Theme, with collaboration, support, and cost-sharing with many other Federal, state, and local entities. The National Hydrography Infrastructure Working Group (NHI WG) is a forum for Federal agencies with direct involvement in the National Hydrography Infrastructure to provide input and collaborate on the direction, development, priorities, management, technologies, use, and resources of the National Hydrography Infrastructure.Join Our Community!We communicate monthly through the NHD Newsletters and Hydrography Advisory Calls, and hold special seminars and workshops as well. Please visit the National Hydrography Dataset Playlist on the USGS YouTube Channel for recorded Advisory Calls and the News tab on the left for more detailed information. For questions, please email nhd@usgs.gov.  The Watershed Boundary Dataset has been updated in several areas along the Massachusetts and Rhode Island coast. Updates for this area are included in the latest version of the WBD data available via the National Hydrography Dataset website.

Year Published: 2020 NHDPlus High Resolution (NHDPlus HR)---A hydrography framework for the Nation Reliable and accurate high-resolution mapping of the Nation’s waters are critical inputs to models and decision support systems used to predict risk and enable response to impacts on water resources. It is necessary to know where the water is and how it relates to features beyond the stream network like forests, cities, and infrastructure. An up-... Buto, Susan G.; Anderson, Rebecca D.
