The USGS has just released the first NHDPlus High Resolution (NHDPlus HR) datasets in Beta version for seven hydrologic regions covering a quarter of the conterminous U.S.

NHDPlus HR extends the rich attribution and functionality present in the NHDPlus Version 2 to the spatial accuracy and detail present in the high resolution National Hydrography Dataset and 1/3 arc-second 3D Elevation Program data. For more information see the NHDPlus High Resolution page.
