The HUs are given a Hydrologic Unit Code (HUC) that ranges from 2 digits to 12 digits. Imagery, roads, and political boundaries were supplied by the New Mexico 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards This data set consists of geo-referenced digital data and associated attributes and is a preliminary release of the 12-digit hydrologic unit Oklahoma Watershed Boundary Dataset, part of the National Watershed Boundary dataset. Originator: USGS and USDA - NRCS . except in coastal or lake front areas where there could be multiple of the HUs. The higher the level, the more digits to the HUC, since jurisdiction boundaries). The U.S. Geological Survey maintains a set of 1:24,000-scale paper topographic maps with hand-drawn drainage divides for streams with drainage areas greater than 5 square miles. A watershed is a natural landscape unit in which all of the precipitation that falls flows to the same outlet or basin. Every hydrologic unit (a watershed or part of a watershed) is identified by a unique HUC, a number containing two to 12 digits. The USGS HUC 12 Watersheds were created by USGS and the Natural Resources Conservation Service (NRCS) as part of a nation-wide mapping effort. Bookmarked by 2 Members About the Map Author.

They nest within the USGS HUC 10 Watersheds. The Watershed Boundary Dataset (WBD) was created from a variety of sources from each state and aggregated into a standard national layer for use in strategic planning and accountability. The position of this in the USGS drainage hierarchy is: Region 12, Subregion 10, Basin 02, Subbasin 03, Watershed 01, Subwatershed 01, thus making the HUC_8 number 12100203 as we used earlier, and the additional subdivision to the HUC_12 level yielding the 32 Subwatersheds in this Subbasin. There are many different entities that develop watershed plans or fund the development of these plans. boundary framework, accounting for all land and surface areas. Puget Sound area map; Flood Hazard Area Maps. There are over 3000 HUC 12 Watersheds in the entire state. Hydrologic Unit Code (HUC) Finder: This is an interactive map of the statewide watershed delineations as developed in 1991 for Indiana and updated nationally in 2009. (218) 788-2694 The Hydrologic Unit Code, or HUC, system is a way to classify watersheds by size. Watershed boundaries define the aerial extent of surface water drainage to a point. Abstract: .

(800) 234-0054 This data layer indicates the boundaries of the United States Geological Survey (USGS) Hydrologic Unit Code (HUC) 12 Watersheds. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as ... USGS/WBD/2017/HUC12, Hydrologic Unit Codes: HUC 4, HUC 8, and HUC 12 The Watershed Boundary Dataset (WBD) maps the full areal extent of surface water drainage for the U.S. using a hierarchical system of nesting hydrologic units at various scales, each with an assigned hydrologic unit code (HUC). Funding was provided by a direct appropriation from the Minnesota State Legislature as part of the Mining and Water Innovation Initiative. The terms watershed and hydrologic unitare used throughout DCR’s web pages. A hydrologic unit has a single flow outlet except in coastal or lakefront areas. Click on your area of interest to find your 8-digit HUC code and a link to a list of watershed groups in your area. Available URL: (http://datagateway.nrcs.usda.gov) [Accessed 22/04/2017]. This data set consists of geo-referenced digital data and associated attributes and is a preliminary release of the 12-digit hydrologic unit Oklahoma Watershed Boundary Dataset, part of the National Watershed Boundary dataset. The number of digits in a HUC is related to 6 levels of detail for the WBD: the lower level polygons cover larger areas than higher level ones. This spatial layer shows the hydrologic unit boundaries for the 12-digit sub-watersheds at a scale of 1:24,000 in the upper Washita River basin in southwestern Oklahoma. the National Watershed Boundary Dataset.

HUCs are delineated and georeferenced to U.S. Geological The NRCS assigned each delineated drainage basin a 14-digit hydrologic-unit code (HUC). Tags watershed, huc 8. Zoom the map to your area of interest, then click on the red watershed labels for more information. The HUC organizes watersheds by a nested size hierarchy, so large scale watershed boundaries for an entire region may be assigned a two-digit HUC, while small scale, local watershed boundaries (within the larger regional watershed) may be assigned a 12-digit HUC. Watershed maps Minnesota has 80 major watersheds located within the 10 major water basins of the state. Suite 100 Lillington NC, 27546. The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution.
