Publication_Date: On-going Publication_Date: Unpublished Material Publication_Time: Unknown Title: IdahoWatersheds_Polys Edition: 1 Geospatial_Data_Presentation_Form: vector digital data Publication_Information: Publication_Place: Idaho Publisher: IDWR Online_Linkage: http://datagateway.nrcs.usda.gov/ Description: Abstract: This data set is an in-progress digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Idaho. 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, linesource and a metadata reference file. 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 40,000 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.

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.

Data_Set_Credit: Funding for the Idaho Watershed Boundary Dataset (WBD) was provided by various contributors throughout the state of Idaho. All representatives contributed a substantial amount of time and salary towards quality review of the dataset. Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.5.1450 Data_Quality_Information: 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 correction 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: In progress Not all fields for all polygons in the .pat are attributed at this time. Some polygons in the Ncontrb_a field might have a 0 value. Not all fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon may or may not be attributed with a 0 for the hu_level. Some of these cannot be attributed until the adjacent states complete their linework at which point the highest level of hydrologic unit can be determined. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The WBD was produced using Digital Raster Graphics (DRGs) 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. 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 DRGs 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. As with the original DRG's, it is cast in the Universal Transverse Mercator projection and is referenced to the NAD27 datum. When the DRG's 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 imagery. Lineage: Process_Step: Process_Description: Metadata imported.

States: States - (REQUIRED) The "States" field includes the names of all state(s) that the subwatershed falls within. The 2-digit postal abbreviation in upper case and in alphabetical order was used, separated with a comma. 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. Hu_10_ds: Fifth Level Downstream Hydrologic Unit Code - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) This field has 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 were not considered for this field. If an HU flows into an ocean or the Gulf of Mexico, this field was populated with "OCEAN" and if a HU flows into one of the Great Lakes the term "LAKE" was used. If a HU flows across international borders, "CANADA" or "MEXICO" was used depending on which country the HU drains into. If an HU is a closed basin, then the term "CLOSED BASIN"was used.

M - “Multiple Outlet” hydrologic unit An area that has more than one natural outlet; for example, an outlet located on a stream with multiple channels. This does not include frontal or water hydrologic units, hydrologic units with artificial interbasin transfers, drainage outlets through karst or ground-water flow, or outlets that cross a stream with an island. This code should be used only in rare instances. W - "Water" hydrologic unit - Hydrologic units that are predominantly water with adjacent land areas, ex. lake, easturies. I - "Island" hydrologic unit - A hydrologic unit that is one or more islands and adjacent water out to the toe of the shore face. U - "Unclassified" hydrologic unit - A hydrologic unit that can't be defined or doesn't fit into one of the types that have been listed. 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 6 12 Subwatershed 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.

Resource_Description: Downloadable Data 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 2000-2003. Idaho Department of Water Resources makes no claims for the data's suitability for other purposes. Idaho Department of Water Resources should be acknowledged as the data source in products derived from these data. The 2000-2003 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 Idaho Department of Water Resources 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.
