UE Hydrography Focus Area

The User Engagement Hydrography Focus Area assists the National Geospatial Program (NGP) in acquiring data and understanding user needs in support of NGP management of 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.

The Hydrography Focus Area is engaged in:

  • Assisting the NGP with its efforts to increase the accuracy and content of the NHD, WBD, and NHDPlus HR;
  • Developing user-friendly, state-of-the-art geospatial products and services for USGS hydrologists and Federal, State, and local water resource managers across the Nation;
  • Working with USGS headquarters staff, USGS scientists, and state and local partners to identify user needs as they relate to the data and services provided by the NGP;
  • Facilitating communications within the water data community; and
  • Promoting hydrography data stewardship from users within states and federal lands because they understand the hydrography around them and are motivated to ensure the accuracy of the NHD to meet their business needs.
