Watershed Boundary Data - Hydrologic Unit
24,000
The dataset was modified by the USDA-NRCS National Cartography & Geospatial Center (NCGC) by creating a seamless dataset for the entire country for all 6 levels. NCGC has included attributes for hydrologic unit codes, hydrologic unit name, downstream hydrologic unit, man-made modifications to overland flow that alter the location of the HU boundary, and HU type for each hydrologic unit level 1-6. NCGC has also added a square miles field to sub-basin. An acres field already exists for each subwatershed. The square miles and acres field was calculated in Albers Equal Area, NAD83 by NCGC. At this time, not all records have attributes for all the fields, but may be filled in by the user for local projects or will be filled in at a later date. NCGC personnel have created 2 shapefiles from the national WBD. One shapefile has attributes for 10 and 12-digit with polygons for the 12-digit HUs. An accompanying line file showing the same linework with the three attribute fields is delivered with the polygon shapefile. For a complete description of the attributes and processes used to delineate hydrologic units to 1:24,000 scale accuracy, please refer to document Watershed Boundary Dataset (WBD) User Guide.

Hydrologic Unit delineation are closed polygons that encompass all area draining toward the lowest point (called outlet or pour point) in the polygon. Because of nominal sizes for the different hydrologic unit level: Watershed (40,000 to 250,000 acres) and Sub-watershed (3,000 minimum, generally 10,000 to 40,000 acres), some polygons do not include all areas up to the drainage divide, but all areas are included up to one or more other upstream hydrologic units. A unique hydrologic unit code is used to identify each hydrologic unit. The hydrologic unit codes start with the 8-digit Sub-basin number that contains the Watershed. Likewise the Sub-watershed hydrologic unit codes start with the 10-digit Watershed number that contains the Sub-watershed. Each hydrologic unit has a unique hydrologic code
Detailed information about the attributes is available from the Watershed Boundary Dataset (WBD) User Guide (wbd_user_guide.doc) that is available with each gateway request.
