1 2 Unknown IDEM.HUC8_2008_NRCS_IN 1 vector digital data 4 5 withheld IDEM.HUC8_2008_NRCS_IN This data set is a complete digital hydrologic unit boundary layer to the Sub-basin (8-digit) 4th level for the State of Indiana. It has been edited to the extent of the INDOT extent of the State Boundary by IDEM Office of Water Quality. (See edits citation and contact information under Entity Attribute-Overview Description-Dataset Overview.) 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, name, size and non-contributing areas. Arcs are attributed with the highest hydrologic unit code for each sub-basin, linesource and a metadata reference file. The Sub-basin hydrologic unit boundaries provide a uniquely identified and uniform method of illustrating large drainage areas. The original (12-digit) dataset from which this layer was derived will be appended to a larger seamless nationally consistant geospatial database as other states complete their portion of the watershed boundary dataset. en 7 Publication date of sources Complete Unknown -88.161308 -84.688259 41.780903 37.755470 403484.437256 692183.624528 4625450.628451 4180925.378508 None HUC Hydrologic Units Hydrologic Unit Code Region Sub-region Basin Sub-basin Watershed Watershed Boundaries boundaries Subwatershed WBD Watershed Boundary Dataset None 10 12 8 None 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 7. 5 should be acknowledged as the data source in products derived from these data. The 7 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. 13 14 mailing address

Federal Standards for Delineation of Hydrologic Unit Boundaries Federal Standards for the Delineation of Hydrologic Unit Boundaries Please refer to the Entity and Attribute Overview for valid values This is a description of attributes by field from the Federal Standards for Delineation of Hydrologic Unit Boundaries 1) Polygon attributes Huc_8 : Eight Digit Hydrologic Unit Code - (REQUIRED) A unique 8-digit code from the USGS map series "Hydrologic Unit Maps". The same number was used in every record that pertains to a subwatershed that resides within the same 8-digit sub-basin.Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Acres: UTMAcres - (REQUIRED) - The field name has been added to best represent the projection on which it was calculated - UTM Zone 16N. This value is the area of subwatershed including non-contributing areas calculated to acres as a whole number, no decimals. The "Acres" field was calculated from the "Area" geometry field. Acres: AlbersAcre - (REQUIRED) - The field name has been changed from ACRES to best represent the projection on which it was calculated - Albers Equal Area. This value is the area of subwatershed including non-contributing areas calculated to acres as a whole number, no decimals. The "Acres" field was calculated from the "Area" geometry field. Ncontrb_a: Non-Contributing Area - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) Drainage areas that do not flow toward the outlet of any hydrologic unit are considered non-contributing. If a non-contributing area is on the boundary between two or more hydrologic units, the non-contributing area is associated with the hydrologic unit adjacent to the low point on the boundary. This attribute should be the total of the non-contributing areas within a hydrologic unit calculated in acres. 2) Line attributes Hu_level: Hydrologic Unit Level - (REQUIRED) This field provides the means to create cartographically pleasing maps. This field is populated with the highest hydrologic unit level (smallest number) for the line (arc) represented by the record. The attribute was recorded using numbers 1 through 6 representing each level with 1 being the highest and 6 the lowest level. An example would be if a line represents a region, subregion, basin, subbasin, watershed, and subwatershed boundary, then this cell was populated with a 1 (Region). Below is a list of numbers used for each level. Level Digit# Name 1 2 Region 2 4 Subregion 3 6 Basin 4 8 Subbasin 5 10 Watershed Linesource: Line Spatial Data Source - (REQUIRED) The Linesource indicates the base map source(s) used to delineate at 1:24,000 scale. The field was populated using one of the standardized code(s) listed below. If more than one code was used, then a comma was used to separate the codes. TOPO24 - Delineation from hardcopy 1:24,000 scale topographic maps TOPO25 - Delineation from hardcopy 1:25,000 topgraphic maps, only Alaska and Caribbean TOPO63 - Delineation from hardcopy 1:63,360 topographic maps, only Alaska and Caribbean DRG24 - Delineation from 1:24,000 scale Digital Raster Graphics DRG25 - Delineation from 1:25,000 Digital Raster Graphics, only Alaska and Caribbean DRG63 - Delineation from 1:63,360 Digital Raster Graphics, only Alaska and Caribbean DEM10 - Derived from 10 meter Digital Elevation Model DEM30 - Derived from 30 meter Digital Elevation Model NED30 - Derived from 30 meter National Elevation Dateset Model EDNA30 - (formally NED-H), derived from 30 meter Elevation Derivatives for National Applications BATH"scale" (ex. BATH24) - Interpreted from NOAA 1:24,000 scale bathymetric data HYPSO"scale" (ex. HYPSO24)- Delineated from 1:24,000 scale contour data ORTHO"scale" (ex. ORTHO12) - Interpreted from 1:12,000 scale Ortho-imagery DEDEM10 - Drainage enforced 10 meter Digital Elevation Model DEDEM30 - Drainage enforced 30 meter Digital Elevation Model GPS - Derived from Global Positioning System LIDAR - Derived from LIDAR IFSAR - Derived from IFSAR data OTH - Other UNK - Unknown All other reference and source maps not listed should be noted in the metadata. Meta_id: Metadata ID Number - (REQUIRED) The Metadata ID is a code that identifies which metadata file applies to the arc. In most cases there is only one metadata file. However, in some cases more than one metadata file was used to identify different groups and/or procedures used to produce the lines. The metadata ID is a 4-character code starting with the 2-letter state postal code, followed by a 2-digit sequence number.
