The 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...

The Desert Landscape Conservation Cooperative Watersheds Map shows hydrographic features including watersheds, streams and lakes at a regional scale. The files provided are graphic design files that can be used to plot a publication-quality, poster-size map. Scale: 1:2,500,000Map poster dimensions: 34 x 44 inchesData sources: Watershed boundaries are from the North American Environmental Atlas by the Commission for Environmental Cooperation, 2010. Hydrography, roads, populated places, and political boundaries are from the National Atlas of the United States, 2004. Natural Earth 1:10m Physical Labels (3.0.0) are derived from Patterson’s Physical Map of the World, 2008.File descriptions: DLCC_Watersheds.ai is an...
