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 designed to be used in general mapping and in the analysis of surface water systems. Using basic NHD features like flow network, linked information, and other characteristics, it is possible to study cause-and-effect relationships, such as determining how a source of poor water quality upstream might affect a fish population downstream.

Watersheds: 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...
