These applications have been developed by NHD users and are listed
here to assist others in applying the NHD. If you are interested in
sharing your NHD application, please contact nhd@usgs.gov.
- StreamStats - The USGS provides users with access to an assortment of analytical tools that are useful for water-resources planning and management, and for engineering design applications, such as the design of bridges. StreamStats allows users to easily obtain streamflow statistics, drainage-basin characteristics, and other information for user-selected sites on streams.
- NHDPlus Offers New Geospatial Data and Tools for Water Quality Managers - Between 1996 and 2000, the Environmental Protection Agency (EPA), the U.S.
Geological Survey (USGS), and other federal, state and local agencies
collaborated to produce the National Hydrography Dataset (NHD), a comprehensive
set of digital geospatial data about surface water features such as
streams, rivers and lakes. These data can be used by water quality
managers to make maps, perform upstream/downstream queries, and link other
water-related information to the NHD network.
In 2006, this interagency collaboration produced NHDPlus, a suite of
application-ready geospatial products that build upon, and extend, the
capabilities of the medium-resolution NHD. NHDPlus integrates the NHD with
the National Elevation Dataset (NED) and the Watershed Boundary Dataset (WBD).
It includes an enhanced NHD stream network with improved names,
value-added attributes (such as stream order), incremental drainage areas
with landscape characteristics, and flow volume and velocity estimates for
pollutant dilution modeling. EPA and USGS have linked many water quality
databases to NHDPlus, including stream gaging stations, water quality
monitoring sites, and impaired waters, enabling these databases to be
queried and analyzed in upstream/downstream order. NHDPlus greatly
enhances the ability of researchers and water quality managers to analyze
and model water quality data. For more information on NHDPlus, visit

- WATERS - Watershed
Assessment, Tracking and Environmental ResultS (WATERS) employs the
NHD as the spatial framework for integrating EPA water program
databases.
- NRIS
Water - The U.S. Forest Service Natural Resource Information
System (NRIS) Water module employs the NHD as its common hydrologic
framework to support aquatic resource decision-making on National
Forests.
- New
England SPARROW - This NHD-based version of the USGS SPARROW
water-quality model aids the development of regional nutrient
water-quality criteria and total maximum daily loads (TMDL) for New
England streams.
- Fish Passage Decision Support System The FPDSS is a web-based application, funded by the U.S. Fish & Wildlife Service, that provides policy makers and the public with information on barriers to fish passage. It uses the NHD for mapping and barrier removal modeling operations.
- Vermont
Flow-Frequency Tool -
The USGS in cooperation with the Vermont
Agency of Transportation developed this NHD-based tool to automate the
calculation of basin characteristics required by flow-frequency
equations that estimate peak-flow frequency and flow duration.
