\"NHDPlusV2\"<\/a>The National Hydrography Dataset Plus<\/a><\/strong> (NHDPlus) is a suite of geospatial products that build upon and extend the capabilities of the NHD<\/a><\/strong> (1:100,000 scale) by integrating it with the National Elevation Dataset<\/a><\/strong> (30M) and the Watershed Boundary Dataset<\/a><\/strong>. Interest in estimating NHD stream flow volume and velocity to support pollutant fate-and-transport modeling was the driver behind the joint U.S. Environmental Protection Agency and U.S. Geological Survey effort to develop NHDPlus.\u00a0 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

NHDPlus has been used in a wide variety of applications<\/a><\/strong> since its initial release in the fall of 2006.\u00a0 This widespread positive response prompted the multi-agency NHDPlus team to design an enhanced NHDPlus Version 2<\/a><\/strong> (NHDPlusV2).<\/p>\n

NHDPlusV2<\/a><\/strong> benefits from significant improvements to its primary ingredient datasets as well as a more robust stream flow estimation process.<\/p>\n
