Fort Worth Texas 76115 (817) 509-3366 Steven.Nechero@ftw.usda.gov Please email questions and requests. Funding and support for the Watershed Boundary Dataset (WBD) were provided by the Natural Resources Conservation Service, the Environmental Protection Agency, and the United States Geological Survey. Representatives from the U.S. Geological Survey and Environmental Protection Agency contributed a substantial amount of time and salary towards quality review and updating of the dataset in order to meet the Federal Standards for Delineation of Hydrologic Unit Boundaries. ESRI ArcCatalog 9.2.6.1500 Feature Class 10% of the attributes were visually reviewed. The accuracy of this data is dependent on the level of detail of the source material and the interpretation procedures for capturing that source. There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. The ArcGIS geodatabase topology tools were used to make corrections using 11 rules including no gaps, no overlaps, identify cooresponding linework for every polygon boundary, and remove duplicate lines with the same beginning and ending nodes. All fields for all polygons are attributed. Some polygons in the Ncontrb_a field might have a 0 value. The WBD was produced using Digital Raster Graphics (DRG's) as the source map. Data completeness for DRG files reflects content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD. The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to the USGS National Map Accuracy Standards. It is estimated that any errors detected were less than 10%. It should also be noted that while general rules of hydrology were used (i.e. natural water flow is downhill), the locations of boundaries is still somewhat subjective as the 1:24,000-scale DRG's do not always provide enough information for identifying the location of the boundaries.

This process occurred over a span of approximately 20 years. withheld 2009 The original dataset was reviewed by USGS personnel using on-screen techniques with DRG's as the base map. All hydrologic units within the dataset that were under 3,000 acres were dissolved out. withheld 2003 The new WBD dataset was reviewed on-screen by USGS, EPA, or NRCS personnel using DRG's and DOQ?s as base maps. Hydrologic Units that were under 10,000 acres (for the 12-digit units) and 40,000 acres (for the 10-digit units) were reviewed and if possible were dissolved out. Along the coastal areas classic watersheds that fell within the federal guidelines size criteria (12-digit: 10,000-40,000 acres, 10-digit: 40,000-250,000 acres) were broken out. If possible the remaining frontals were left as their own units. Frontals that did not meet the size criteria were grouped together with other frontals within the overall 8-digit or 10-digit unit. Hydrologic units what were greater than 40,000 acres (12-digit units) and 250,000 acres (10-digit units) were reviewed. If possible these unit where then broken down into smaller units that met the size criteria. In some cases additional breaks within the unit would not have made sense or have been very useful (example: When the majority of the unit was made up by a major waterbody feature such as a lake or reservoir and the surrounding tributaries were too small to break out as their own unit). In these instances the unit was left big. Source_Used_Citation_Abbreviation: USGSDRG withheld 2005 Hydrologic units from surrounding states were used to edgematch watershed boundaries. withheld 2005 Original dataset attribution was reviewed and revised to reflect the updates and changes made to the dataset. These revisions to the attribution were also made to ensure that the dataset met the Federal Standards for Delineation of Hydrologic Unit Boundaries. The NHD was used during this process to help with the naming and downstream coding of each unit. In some instances there were name hydrologic unit name discrepancies between the NHD and what was printed on the DRG's. In these instances the DRG's were used instead of the NHD. withheld withheld 2005 withheld First draft of metadata created by Laura Davenport using METADATA Editor in ArcCatalog ver. 9.1 sp.1. 20070124 Second draft of metadata created by Laura Davenport using METADATA Editor in ArcCatalog ver. 9.2 sp.6. 20090817 Dataset copied. withheld 20120201 17015300 Vector Simple FALSE 6 TRUE FALSE North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 GCS_North_American_1983 not applicable 1.000000 not applicable Implicit coordinate not applicable 1.000000 not applicable Implicit coordinate HU12_polygon identifies watershed boundaries (as polygons) n/a Feature Class 6 OBJECTID OBJECTID OID 4 10 0 Internal feature number.
