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
Seamless Data
Not quad based Online access GIS ready Variable-resolution Feature-level metadata Update features as needed by transactions Versions Stable identifiers
100K NHD and 24K NHD

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 – Applications, Related Programs, and Tools (2)
WATERS - EPA Water Assessment, Tracking & Environmental Results
Section 303d, Clean Water Act TMDL - Total Maximum Daily Load Section 305b, water quality assessment STORET - data STOrage and RETrieval
system - water quality data repository

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
