National Hydrography Dataset (NHD) is a feature-based database that
interconnects and uniquely identifies the stream segments or reaches that make
up the nation's surface water drainage system. NHD data was originally
developed at 1:100,000-scale and exists at that scale for the whole country.
This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds
detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and
the Virgin Islands was developed at high-resolution, not 1:100,000 scale.)
Local resolution NHD is being developed where partners and data exist. The NHD
contains reach codes for networked features, flow direction, names, and
centerline representations for areal water bodies. Reaches are also defined on
waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and
Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National
Spatial Data Infrastructure framework criteria established by the Federal
Geographic Data Committee.</span><span style='font-size:11.5pt; font-family:"Helvetica",sans-serif; color:#4C4C4C;'> </span></p>
