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.
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 the 1:24,000-scale NHD. The USGS files were used for spatial accuracy and the EPA files were used for attribute information.

What is the positional accuracy of the National Hydrography Dataset (NHD)?
Original hydrographic data were compiled to meet National Map Accuracy standards . These standards have been maintained in the process of creating the NHD. At 1:100,000 scale, ninety percent of well-defined features are within 167 feet (0.02 inches at map scale) of their true geographic position. When higher resolution data are created and submitted, the positional accuracy may vary due to...

The U.S. Geological Survey is developing a new geospatial hydrographic framework for the United States, called the National Hydrography Dataset Plus High Resolution (NHDPlusHR), that integrates a diversity of the best-available information, robustly supports ongoing dataset improvements, enables hydrographic generalization to derive alternate representations of the network while maintaining featurAuthorsRoland J. Viger, Alan H. Rea, Jeffrey D. Simley, Karen M. HansonThe National Map hydrography data stewardship: what is it and why is it important?
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) were designed and populated by a large consortium of agencies involved in hydrography across the United States. The effort was led by the U.S. Geological Survey (USGS), the U.S. Environmental Protection Agency (EPA), and the Natural Resources Conservation Service (NRCS). The high-resolution NHD dataset, completed in 2007,AuthorsDave ArnoldWatersheds: where we live
We all live in a watershed. Animals and plants all live there with us. Everyone affects what happens in a watershed by how we treat the natural resources. So what is a watershed? It is the land area that drains water to a stream, river, lake, or ocean. Water travels over the Earth's surface across forest land, farm fields, pastures, suburban lawns, and city streets, or it seeps into the soil and mAuthorsStephen Vandas, Frank FarrarGround water: the hidden resource
Ground water is water underground in saturated zones beneath the land surface. Contrary to popular belief, ground water does not form underground "rivers." It fills the pores and fractures in underground materials such as sand, gravel, and other rock. If ground water flows from rock materials or can be removed by pumping from the saturated rock materials In useful amounts, the rock materials are cAuthorsStephen Vandas, Frank Farrar - News
