Overview: This project represented a partnership between US Geological Survey (USGS) National Geospatial Program, the US Fish and Wildlife Service (on behalf of the Desert Landscape Conservation Cooperative (DLCC)), and the Center for Geographical Studies (CGS) at California State University, Northridge (CSUN). The project focused on updates and improvements to the high resolution National Hydrography Dataset (NHD) through the addition and/or improvement of NHD polygon, line, and point features in effort to fully realize a more robust and accurate NHD for priority areas within the DLCC geography. The work performed was designed to support the science objectives for the DLCC and its partners through the use of an updated NHD. The work [...]

This project provides direct improvement to the national NHD database in advance of planned generation of high resolution NHDPlus for NHD Region 15; it provides improved hydrograhy for the cartographic rendering of blue line streams for the next edition of US Topo for CA and AZ and other areas to be determined; it provides the DLCC with a more accurate surface water map to support numerous lines of scientific inquiry and land management decisions as described in the project description.
