  Description:
    Abstract:
      This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Wyoming.This data set consists of geo-referenced digital data and associated attributes created in accordance with the "Federal Standards For Delineation of Hydrologic Unit Boundaries 12/06/01"
      (http://www.ftw.nrcs.usda.gov/huc_data.html). The data set was developed by digitizing watershed boundary lines using 1:24,000 Enhanced Digital Raster Graphics (DRG-E) geo-referenced topographic image base maps and 1:100,000-scale draft boundary lines. The National Elevation Dataset (NED) was used to produce the 1:100,000-scale preliminary draft boundaries. Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downsteam hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file.
      Two separate shapefiles were created for downloading purposes. One with arcs (wy_hu12arc.shp) and one with polygons (wy_hu12poly.shp). The same metadata is used for both shapefiles. Only the arc attributes will be found in the wy_hu12arc shapefile. Similarly, only the poly attributes will be found in the wy_hu12poly shapefile.
    Purpose: 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 consistant geospatial database as other states complete their portion of the watershed boundary dataset. Two separate shapefiles were created for downloading purposes. One with arcs (wy_hu12arc.shp) and one with polygons (wy_hu12poly.shp). The same metadata is used for both shapefiles. Only the arc attributes will be found in the wy_hu12arc shapefile. Similarly, only the poly attributes will be found in the wy_hu12poly shapefile.

  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      The accuracy of this data is dependent on the level of detail of the source material and the interprtation procedures for capturing that source. The primary limiting factor for the level of detail of the source is the scale (1:24,000) of the enhanced digital raster graphic (DRG-E). The map scale determines the level of content that may be extracted from the given source during digitization.
      It should be noted that no 1:24,000-scale linework was available for the Black Buttes DRG-E (USGS Quad Id # 41008-E5). Boundary locations were determined using the 1:100,000-scale DRG-E and the digital orthophoto quads. The following huc_12s intersect the black buttes quad: 140401050203, 140401050205, 140401050206, 140401050207.
      1) 100% of the boundary locations were visually verified using the draft 1:100,000-scale boundaries and the enhanced digital raster graphics (DRG-E) as a reference. Additionally, 10% of the boundary locations were reviewed by the Interagency Hydrologic Unit Group (IHUG). Ocassionally (<5%) local knowledge was used to verify boundary locations or digital orthophoto quads of the area were reviewed.
      2) 100% of the huc_12, huc_10 and huc_8  values were verified visually for accuracy upon attribute transfer from the 1:100,000-scale draft data and then again once the entire coverage was complete. The huc_12 values were also checked to ensure no duplicate numbers were found
      3) 100% of the state attribute was visually checked.
      4) The ncontrb_a areas were first identified during the creation of the 1:100,000-scale data. Areas larger than 3000-acres were attributed as noncontributing hydorlogic units. 100% of the noncontributing area were verified using the DRG-Es during the naming process.
      5)The hu_10_ds and hu_12_ds were visually verified using the national hydrographic dataset and where necessary, the DRG-E.
      6) The huc_10_name and hu_12_name attributes were checked for duplicates and to ensure that the names comply with the Federal Standards for the Delineation of Hydrologic Unit Boundaries.
      7) The hu_10_mod and hu_12_mod attributes were visually verified for accuracy of interbasin transfers during the semi-automated attribution process. Dam locations were identified by looking at the NHD waterbodies in each huc_8 and comparing the pour point locations of the huc_8 boundaries.
      8) 100% of the hu_10_type and hu_12_type attributes were visually verified.
  Logical_Consistency_Report: There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. Arc/Info's topological checking program CLEAN was used to correct intersections without nodes, identify unclosed polygons and remove duplicate lines with the same beginning and ending nodes. All sliver polygons were removed either using eliminate, merge or manually in ArcEdit.
  Completeness_Report:
    All fields for all polygons in the .pat are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon are attributed with a 0 for the hu_level. These cannot be attributed until the adjacent states complete their linework at which point the hightest level of hydrologic unit can be determined.

    It should be noted that no 1:24,000-scale linework was available for the Black Buttes DRG-E (USGS Quad Id #41008-E6). Boundary locations were determined using the 1:100,000-scale DRG-E and the digital orthophoto quads. The following huc_12s intersect the Black Buttes quad: 140401050203, 140401050205, 140401050206, 140401050207.

    The WBD was produced using Enhanced Digital Raster Graphics (DRG-Es) digital images as source map. Data completeness for DRG files reflect content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to USGS National Map Accuracy Standards. Digitized line locations were held to the +/- 40 foot accuracy standards by ensuring that all lines were within a 12 meter buffer of where visual interpretion put the actual boundary. Any lines outside the buffer were corrected. It is estimated that the errors detected were less than 10%.  It should be noted that while general rules of hydrology were used (i.e. water flows downhill), the location of boundaries is still somewhat subjective as the 1:24,000-scale DRG-E do not always provide enough information for identifying the location of the boundaries. In these instances group consensus was used. Please refer to the methods section for more details on watershed delineation rules. Unquantifiable errors may be associated with coordinate shift (fuzzy tolerance was set to 0.000000001 meters, double precision), dangle (set to 15 meters). The default was used for all other ArcEdit tolerances.
        It should be noted that the data was digitzed using NAD27 horizontal datum as that is the native datum of the digital raster geographics. The data was then projected to NAD83 horizontal datum as requested by the NRCS.
        If the Wyoming data is reprojected to nad83 and overlaid on the DRG-Es with the NAD83 DRG-Es it can be assumed that the boundaries will be off by less than 2 meters. As with the original DRGs, DRG-E is cast in the Universal Transverse Mercator projection and is referenced to the NAD27 datum. When the drg-es are used in the NAD83 datum the alternate world files only approximate the NAD83 by shifting the coordinates of the imagery. The total error introduced using this shift is less than 2 meters for all DRG-E imagery.

    Process_Step:
      Process_Description:
        1) Phase I - Draft Delineations at 1:100,000-scale
        a) In ArcInfo Using blind pass processing on the USGS National Elevation Dataset (NED) 5000 pixel catchments were created
        b) Using the guidelines for creating watersheds outlined in the Federal Standards the NED derived watersheds were aggregated using tools created in ArcView. Reference Data included 1:100,000-scale National Hyrodgraphy Dataset reach code and 100K Digital Line Graph Hydrography (Strahler Order) and existing linework from USFS, NPS and adjacent states.
        c) The aggregated watersheds were attributed using tools created in ArcView. The attributes include 4th level/8 digit, 5th level/10 digit and 6th level/12 digit hydrologic Unit Codes (HUC). Comments regarding necessary editing (e.g. pourpoint adjustment) were also added with tools.
        d) Edit and dissolve NED derived sheds on 5th and 6th level HUCs
        e) Draft boundaries were reviewed and edits suggested by the Interagency Hydrologic Unit Group, neighboring states and other cooperators.
        f) Edits were made to the draft boudaries
        g) The final draft boundaries were checked for size appropriateness, pour point locations, and HUC attribute according to the Federal Standards.
        2) Phase II - 1:24,000-scale delineations
        a) Using the draft boudaries as a guide and the Digital Raster Graphics - Enhanced (DRG-E) as a background the
        1:24,000-scale boudaries were digitized as a shapefile using head-up digitizing in ArcView. Digitizing usually occured zoomed in at 1:7,000-1:12,000-scale. The general watershed boundary delineation rules used to digitize the watershed boundaries include: 1) drawing boundaries perpendicular to contours, 2) never crossing a waterbody or where contours indicate the location of overland flow would go (except as a pourpoint) and 3) when delineating along a ridgetop the boundary would be located closer to the side of the ridge with the steepest gradient. It should be noted that while general rules of hydrology were used the location of boundaries is still somewhat subjective as the 1:24,000-scale DRG-E do not always provide enough information for identifying the location of the boundaries in such instances group consensus was used. HUC 14040106 was digitzed by the United States Geolgic Survey  in Utah. All of the steps noted below were carried out on the line work completed by Utah.
        b) All 1:24,000-scale linework was reviewed internally and corrections made accordingly.
        c) 10% of the 1:24,000-scale linework was then reviewed by the Interagency Hydrologic Unit Group (IHUC).
        d) The shapefile was converted to a polygon coverage in ArcInfo
        e) Topology was created in Arc/Info using CLEAN a dangle length of 15 and a fuzzy tolerance of 0.000000001. The coverage was created using double precision.
        f) The draft 1:100,000-scale boundaries were converted to a polygon coverage and cleaned using defaults
        g) Attributes from the 100,000k draft were transfered to the 1:24,000-scale coverage using the PUT command
        h) Additional attributes were added using some extensions and scripts created in ArcView. These included the HucNamer extension, the downstream HUC tool, flow modification NHD query tool.
        i)The remaining attributes required by the Federal Standard were added by querying the appropriate data in ArcView.

      Huc_8 : Eight Digit Hydrologic Unit Code - (REQUIRED)
      A unique 8-digit code from the USGS map series "Hydrologic Unit Maps".  Use the existing code for the sub-basin where the subwatershed resides; do not change this code.  The same number should be 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.

      Huc_10:	Ten Digit Hydrologic Unit Code - (REQUIRED)
      This field provides a unique 10-digit code for each watershed.  Add two digits to the end of the existing 8-digit code, therefore resulting in a 10-digit number.  This same number should be used in every record that pertains to a subwatershed that resides within the same 10-digit watershed.Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. It should be noted that the polygons that cross into Idaho were numbered by Idaho and are not consistent with the above methods. Affected huc_8s include: 17040202, 17040204 and 17040104.

      Huc_12:	Twelve Digit Hydrologic Unit Code - (REQUIRED)
      This field provides a unique 12-digit code for each subwatershed.  Add two digits to the end of the existing 10-digit code, therefore creating a 12-digit number.Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. It should be noted that the polygons that cross into Idaho were numbered by Idaho and are not consistent with the above methods. Affected huc_8s include: 17040202, 17040204 and 17040104.

      Acres: 	Acres - (REQUIRED)

      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, determine the low point along the non-contributing area boundary.  The non-contributing area should be 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.

      Populate this field with the 10-digit code of the 5th level hydrologic unit that is receiving the majority of the flow from the watershed that the 6th level HU falls within.  Outlets created by ditching or other artificial drainage are not to be considered for this field. If an HU flows into an ocean or the Gulf of Mexico populate this field with "OCEAN" and if a HU flows into one of the Great Lakes use the term "LAKE".  If a HU flows across international borders use "CANADA" or "MEXICO" depending on which country the HU drains into.  If an HU is  a closed basin, then populate this record with the term "CLOSED BASIN".

      Hu_10_name: 	Fifth Level Hydrologic Unit Name - (FIELD REQUIRED, ATTRIBUTES OPTIONAL)
      This field is for officially recognized names only.  Populate this field by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol".  Populate this field with the identical name for all 6th level hydrologic units that fall within the same 10-digit HU. The name used to attribute the watershed should be used only once within a 4th level unit. Some 10-digit HU were assigned the huc_10 number when no GNIS name was identified on the DRG-Es.

      Hu_10_mod: 		Fifth Level Hydrologic Unit Modifications - (REQUIRED)
      This field should identify any type of modifications to natural overland flow that alters the location of the hydrologic unit boundary for a 10-digit watershed.  In the attribute field, identify from most significant to least significant modification(s).  Use one or more of the following abbreviations in uppercase to identify your modification(s).

      Meta_id:	Metadata ID Number - (REQUIRED)
      Metadata ID is a code that identifies which metadata file applies to the arc. In many cases there will only be one metadata file. However, in some cases more than one metadata file may be created to identify different groups and/or procedures used to produce the lines. These separate metadata files may be identified for each separate arc. The metadata ID should be a 4-character code starting with the 2-letter state postal code, followed by a 2-digit sequence number. For example "OK01", "ID02", etc.

  Distribution_Liability: 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 Wyoming. WyGISC (Wyoming Geographic Information Science Center) makes no claims for the data's suitability for other purposes. WyGISC should be acknowledged as the data source in products derived from these data. The Wyominig 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 WyGISC or 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.
