This lesson will provide a brief overview of the National Hydrography Dataset, Watershed Boundary Dataset and 3D Elevation program. This lesson will also discuss NHDPlus and introduce NHDPlus high resolution and tell you how to get the data.
In what scale are the data in the National Hydrography Dataset (NHD)?
Scales for data in the National Hydrography Dataset:
- Conterminous United States, Hawaii, and the Virgin Islands, medium resolution - 1:100,000-scale
- Conterminous United States, Hawaii, and the Virgin Islands, high resolution - 1:24,000-scale
- Puerto Rico - 1:20,000-scale
- Alaska - 1:63,360-scale
Users are encouraged to work with their state's principal steward to produce and submit data at higher resolutions.
High-resolution data and local-resolution data are combined into a single, best-resolution product database, so some areas having larger than 1:24,000-scale data. For example, the state of Vermont has data scaled at 1:5,000 for the entire state.

What is the National Hydrography Dataset (NHD)?
The National Hydrography Dataset (NHD) is a digital vector dataset used by Geographic Information Systems (GIS) to define the spatial locations of surface waters and is designed to provide comprehensive coverage of surface water data for the U.S. The NHD contains features such as lakes, ponds, streams, rivers, canals, dams, and stream gages in a relational database model system. These data are...
What sources were used to produce the National Hydrography Dataset (NHD)?
The National Hydrography Dataset (NHD) is a combination of USGS hydrologic digital line graph (DLG) files and Environmental Protection Agency (EPA) reach files, version 3.0 (RF3). U.S. Forest Service Cartographic Feature Files (CFF) and USGS Tagged Vector Hydro (TVH) captured from 7.5-minute printed maps were also used. Some states also contributed their own stream layer data to the compilation of...
