National Hydrography Dataset Plus High Resolution (NHDPlus HR)
https://www.sciencebase.gov/catalog/item/57645ff2e4b07657d19ba8e8
The High Resolution National Hydrography Dataset Plus (NHDPlus HR) is an integrated set of geospatial data layers, including the best available National Hydrography Dataset (NHD), the 10-meter 3D Elevation Program Digital Elevation Model (3DEP DEM), and the National Watershed Boundary Dataset (WBD). The NHDPlus HR combines the NHD, 3DEP DEMs, and WBD to create a stream network with linear referencing, feature naming, "value added attributes" (VAAs), elevation-derived catchments, and other features for hydrologic data analysis. The stream network with linear referencing is a system of data relationships applied to hydrographic systems so that one stream reach "flows" into another and "events" can be tied to and traced along the network. The VAAs provide capabilities for upstream and downstream navigation with linear referencing, analysis, and modeling. The elevation derived catchments are used to associate other landscape attributes, such as land cover, with stream segments.
These data are intended for geographic display and analysis at the watershed level. The data should be displayed and analyzed at scales appropriate for 1:24,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.

No access constraints as all data are open and non-proprietary. However, users should be aware that temporal changes may have occurred since this data set was collected and that some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Acknowledgment of the U.S. Geological Survey would be appreciated for products derived from these data.

Attribute accuracy was evaluated.
Data were processed with ArcGIS 10.2.2, and should not contain any topological errors. Network connectivity was verified by tracing upstream from all outlets. Topology between streams, waterbodies, coastlines, and gages was checked in the national data sets to ensure features were vertically integrated.
Please see http://nhd.usgs.gov/ for data feature details.
Horizontal accuracy for source data may be available in the original source product metadata file if one was provided.
Vertical accuracy for elevation data may be available in the original source product metadata file if one was provided.

NHD
The NHD serves as a comprehensive national flow network for use with surface water related geospatial information. The NHD uses "ReachCodes" and "Measure" fields to reference surface water events. A snapshot of the conterminous United States high resolution 1:24,000 or better NHD was used as the baseline framework from which enhancements to the network were built upon. Enhancements include feature names, network connectivity and network flow relationships. This enhanced NHD version was then used in conjunction with the 3DEP DEMs, and WBD to create a hydro-enforced DEM, for generation of the catchment Grid/shapefile, and flow direction/accumulation Grids. The enhanced NHD was used to compute and assign flowline Value Added Attributes (VAAs) to this network.

3DEP DEM
3DEP elevation data were used in combination with NHD and WBD to create a hydro-enforced, NHDPlus HR Catchments, surface flow direction and accumulation Grids. Stream elevations from 3DEP DEMs were used to help derive stream slope and stream velocity. 3DEP DEM snapshot dates used were as follows: August 2010 - VPU04 February 2011 - VPUs 05, 06 June 2011 - VPU 17 August 2011 - VPUs 07, 10L, 10U, 11, 18 December 2011 - VPUs 01, 02, 03N, 03S, 03W, 08, 09, 12, 13, 14, 15, 16 January 28, 2014 - VPUs 20, 21, 22MA February 10, 2014 - VPU 22AS February 19, 2014 - VPU 22GU

WBD
12-digit Hydrologic Unit (HUC 12) divides from the Watershed Boundary Dataset (WBD) were used as ridgeline enforcment input in a process called "walling" in the production of hydro-enforced DEMs. Closed basin designations, from the HUC 12 polygon data were used to impose "sinks" in the hydro-enforced DEMs. These DEMs are the source data from which NHDPlus HR Catchments are delineated from. Catchments with corresponding boundaries in the WBD generally agree with the WBD to within one or two 10-m grid cells. Some larger differences between catchment boundaries and WBD boundaries do exist, however. NHDPlus HR Flow Direction and Accumulation Grids are hydrologic derivative products of the hydro-enforced DEMs. Dates of WBD snapshots used were as follows: August 31, 2010 - VPU 04 March 10, 2011 - VPUs 05, 06 July 14, 2011 - VPU 17 September 16, 2011 - VPU 10L October 7, 2011 - VPU 10U November 14, 2011 - VPUs 07, 11 December 2, 2011- VPU 18 December 21, 2011 - VPUs 09, 12 February 1, 2012 - VPUs 01, 02, 03N, 03S, 03W, 08, 13, 14, 15, 16 October 2014 - VPUs 20, 21 April 2015 - VPUs 22AS, 22GU, 22MP The February 1, 2012 WBD snapshot used to migrate NHD medium resolution Reachcode assignment to agree with WBD HUC 8 codes. Reachcodes in VPUs 20, 21, 22AS, 22GU, and 22MP agree with their WBDSnapshots.
