National Hydrography Dataset

A comprehensive set of digital spatial data

that contains information about: naturally occurring and constructed

bodies of water natural and artificial paths through which

water flows related hydrographic entities.

National Hydrography Dataset

Stream network – streams, canals, other paths: 80%

Water bodies – lakes, reservoirs, other areas: 14%

Landmarks – dams, bridges, geysers, other items: 6%

National Hydrography Dataset

National program Combine hydro spatial data programs of

USGS DLG EPA RF3 USFS CFF other national, state,

and regional partners

Coordinate update efforts

NHD – Applications and Related Programs

How is NHD used?

Support inventory, analysis, visualization, mapping, modeling . . .

Water quality, flooding, fish . . .

NHD – Applications, Related Programs, and Tools (1) RIT - Reach Indexing Tool for NHD -

georeferencing surface water databases to NHD BASINS - Better Assessment Science Integrating

Point and Nonpoint Sources - integrated watershed environmental modeling

CWAEM - Clean Water Act Effects Model - basic water quality modeling and economic analysis

NAWQA - National Water-Quality Assessment Program

NLFWA - National Listing of Fish and Wildlife Advisories

NHD Stewards

• The NHD is a living dataset• Revision updates needed• Quality updates needed• Organizations closest to the hydrography are most aware of ground truth• Such organizations should have the opportunity to serve as stewards• The USGS will assist
