| Abstract | The high resolution 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. The original medium-resolution NHD (scale 1:100,000) was created by merging the USGS 1:100,000 DLG linework with the USEPA RF3 (Reach File 3) attribution. High resolution NHD (scale: 1:24,000) adds more accurate and detailed stream and lake information to the original 1:100,000-scale NHD. High resolution NHD contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent waterbodies (lakes) and the approximate shoreline of Lake Superior. USGS is working in cooperation with several agencies to create high-resolution NHD data for all major watersheds in Minnesota, using the DNR 1:24,000 streams and lakes linework as the base. These agencies include the Minnesota Pollution Control Agency, the Land Management Information Center, the Spatial Analysis Research Center at St. Cloud State University, and the U. S. Forest Services Offices in the Chippewa and Superior National Forests. |

| Ordering Instructions | These data sets can be obtained by USGS Cataloging Unit (DNR Major Watershed) from the USGS NHD Website at http://nhd.usgs.gov/data.html Click on the link 'Obtaining NHD Data.' This links to a web mapping application which enables you to zoom in to the area of interest, view the CU's which have been completed, view metadata, and download the zipfile containing NHD data and metadata for the CU of choice. (In the map application, make visible the layer 'High Res Subbasins'). There are also instructions for going directly to the ftp site and downloading data for the CU of choice. This option works if you already know the CU number. |

| Title | National Hydrography Dataset - High Resolution - Minnesota | |||
| Abstract | The high resolution 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. The original medium-resolution NHD (scale 1:100,000) was created by merging the USGS 1:100,000 DLG linework with the USEPA RF3 (Reach File 3) attribution. High resolution NHD (scale: 1:24,000) adds more accurate and detailed stream and lake information to the original 1:100,000-scale NHD. High resolution NHD contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent waterbodies (lakes) and the approximate shoreline of Lake Superior. USGS is working in cooperation with several agencies to create high-resolution NHD data for all major watersheds in Minnesota, using the DNR 1:24,000 streams and lakes linework as the base. These agencies include the Minnesota Pollution Control Agency, the Land Management Information Center, the Spatial Analysis Research Center at St. Cloud State University, and the U. S. Forest Services Offices in the Chippewa and Superior National Forests. | |||
| Purpose | The National Hydrography Dataset is designed to provide comprehensive coverage of hydrologic data for the United States. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). Because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications. The NHD also incorporates the National Spatial Data Infrastructure framework criteria set out by the Federal Geographic Data Committee. | |||

| Lineage | USGS and USEPA provide tools for creating high-resolution NHD data, using 1:24,000 streams and lakes linework scanned from 1:24,000 quad maps, medium-resolution NHD, and conflation and editing routines. In Minnesota, high-resolution NHD is generally created using the Minnesota Department of Natural Resources 1:24,000 streams and lakes linework rather than the DLG data. Additional local information is available for some CU's. Because of this, Minnesota procedures differ in the pre-conflation stage from the standard USGS routines, but follow the standard for conflation and post-conflation processing. Metadata outlining data source and processing procedures is provided with the data download for each CU, and is accessible from the USGS NHD site. See dataset specific metadata for more information on actual processing steps. |
