The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 250,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is 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 dataset will be appended to a larger seamless nationally consistent geospatial database as other states complete their portion of the watershed boundary dataset. |

The dataset was created by the coordinated effort between multiple agencies including; Arkansas Natural Resources Commission (ANRC), USDA Arkansas, USDA Forest Service- Ozark-St. Francis National Forest, USGS Arkansas, USGS Utah, USGS Mississippi, Arkansas Game and Fish Commission, Arkansas Heritage Commission, Arkansas GIS User's Forum, Arkansas Department of Environmental Quality, Arkansas Geologic Commission, University of Arkansas at Monticello and University of Arkansas at Fayetteville. NRCS provided the oversight and did a major portion of the delineations and attribution in the eastern portion of the state and portions of the Upper White River area, as well as some areas along the middle and lower portions of the Arkansas side of the Mississippi. Over the past 1-1/2 years USGS in Arkansas as well as USGS in Utah have, under an agreement with NRCS and the State of Arkansas, completed the remainder of the states line work and attribution, appended the dataset together. |

| description:
|
This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Arkansas. This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02"(http://www.ftw.nrcs.usda.gov/huc_data.html). Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, line source and a metadata reference file. |

The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document. It is strongly recommended that this data is directly acquired from the distributor and not indirectly through other sources which may have changed the data in some way. These data should not be used at scales greater than 1:24,000 for the purpose of identifying hydrographic watershed boundary feature locations in Arkansas. The NRCS should be acknowledged as the data source in products derived from these data. The Arkansas Watershed Boundary Dataset is public information and may be interpreted by all organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application of the data. Federal, State, or local regulatory bodies are not to reassign to the Natural Resources Conservation Service any authority for the decisions they make. The Natural Resources Conservation Service will not perform any evaluations of these maps or purposes related solely to State or local regulatory programs. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can result in misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the small scale. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data from the source distributor. |
