Hydrologic units are intended to be used as a tool for water-resource management and planning activities particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The WBD complements the National Hydrography Dataset (NHD) and supports numerous programmatic missions and activities including: watershed management, rehabilitation and enhancement, aquatic species conservation strategies, flood plain management and flood prevention, water-quality initiatives and programs, dam safety programs, fire assessment and management, resource inventory and assessment, water data analysis and water census.", "summary": "The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data.", "title": "wbd", "tags": [ "inlandWaters", "Watershed Boundary Dataset", "WBD", "Hydrologic Units", "Hydrologic Unit Code", "HUC", "Region", "Sub-region", "Basin", "Sub-basin", "Watershed", "Subwatershed", "2-digit", "4-digit", "6-digit", "8-digit", "10-digit", "12-digit" ], "type": "Map Service", "typeKeywords": [ "ArcGIS", "ArcGIS Server", "Data", "Map Service", "Service" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -115.706097668341, 25.4302657490688 ], [ -90.1430030444787, 41.6420247311966 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "GCS_North_American_1983", "accessInformation": "U.S. Department of Agriculture - Natural Resource Conservation Service", "licenseInfo": "", "portalUrl": "" }
