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" and "Federal Standards for Hydrologic Unit Delineation version 2.0 October 1, 2004" (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 North Dakota. The North Dakota Department of Health - Division of Water Quality should be acknowledged as the data source in products derived from these data. The North Dakota 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 North Dakota Watershed Boundary Dataset (WBD) was provided by many sources. Direct funding from two ND GIS Technical Committee data acquisition grants, US Bureau of Reclamation Technical Assistance to States program, Cooperative Agreements with the U.S. Geological Survey as well as an EPA Wetlands Grant, EPA 319 Non-Point source pollution prevention program funds, an EPA Regional Geographic Initiative Grant, and direct funding from the state of North Dakota through the agency's budget. Representatives from the North Dakota State Water Commission, North Dakota Geological Survey, North Dakota Game and Fish Department, U.S. Geological Survey -Bismarck Water Resource District Office, US Forest Service Dakota Prairie Grasslands, and as well as the NRCS-North Dakota State Office contributed a substantial amount of time and salary towards the initial creation of data and later quality review of the dataset. Original delineations were completed by NRCS personnel, private contractor Hydrologic Unit Delineation, Inc. or Lynn Bergman, independant hydrologist (Upper Souris). 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: The ArcGIS 9.x geodatabase model was used. Topology was created using the wbd_topology2009.rul template to assure that there are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. Topological corrections were made using the toplogical editing toolbar in ArcInfo Desktop 9.2. Corrections made included intersections without nodes, identify unclosed polygons and remove duplicate lines with the same beginning and ending nodes. All sliver polygons and overlaps were removed either using eliminate or merge. Completeness_Report: All required fields for all polygons in the .pat are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All required fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon on the Canadian border are attributed with a 0 for the hu_level. These cannot be attributed at this time. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The ND WBD was produced using paper USGS 7.5 minute topographic maps produced between 1947-1986 and Digital Raster Graphics (DRG) digital images. Refinment of lines was completed using National Agricultural Imagery Program imagery (NAIP) from 2003, 2005 and 2006 as well as aerial imagery from Cass County, ND, Metropolitan Planning Organization of Bismarck, Mandan and Lincoln, and City of Fargo aerial imagery as source maps. 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 interpretation 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 do not always provide enough information for identifying the location of the boundaries. In these instances group consensus, hydrologic best judgement and the use of aerial imagery 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. Subbasins 09020109, 09020202, 09020203, 10130101, 10130103, 10130104 were reviewed to meet the new Federal Standards, even though they were not delineated when those standards were released. All other subbasins were reviewed according to previous version of the Federal Standards.

Scanned lines were then vectorized in ArcInfo. The ND SWC and their contractor, HUD, Inc. completed a similar process for the Devils Lake basin, James River Headwaters, Pipestem, Upper James and Elm-maple rivers. See process step for more description. Source_Information: Source_Scale_Denominator: 6000 Type_of_Source_Media: online Source_Citation_Abbreviation: OTH Source_Contribution: Aerial images from the cities of Bismarck, Mandan and Lincoln as well as aerial images from Cass County, ND were used for further refinement of line placement. Process_Step: Process_Description: Level 5 (10-digit) watersheds were delineated within a nested hierarchical structure using the existing Level 4 (8-digit) watershed delineation as a starting framework. When neccessary, corrections were made to the fourth level line. Level 6 (12-digit) subwatersheds were then nested within the 5th level framework. The typical size of a level 6 watershed is 10,000 to 40,000 acres. The order of precedence for establishing the pour point of a sub-watershed is: (1) at the outlet of a lake or pond; (2) at a confluence; (3) at some topographic feature, such as a natural gap in topography; (4) at a dam; (5) to meet the acreage limitations of the Federal Standard.

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. Huc_10: Ten Digit Hydrologic Unit Code - (REQUIRED) This field provides a unique 10-digit code for each watershed. This same number was 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. Huc_12: Twelve Digit Hydrologic Unit Code - (REQUIRED) This field provides a unique 12-digit code for each subwatershed. 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: Acres - (REQUIRED) Area of subwatershed including non-contributing areas calculated to acres as a whole number, no decimals. The "Acres" field was calculated from the "Area" field. 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. Hu_10_name: Fifth Level Hydrologic Unit Name - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) This field used officially recognized names only. This field was populated by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol". The name used to attribute the watershed was used only once within a 4th level unit. Hu_10_mod: Fifth Level Hydrologic Unit Modifications - (REQUIRED) This field identifies any type of modifications to natural overland flow that alters the location of the hydrologic unit boundary for a 10-digit watershed. This field shows the most significant to least significant modification(s) to the watershed boundary. One or more of the following abbreviations was used. SC - Stormwater Canal or Drainage Canal ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal or Navigation Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Noncontributing Area KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel or Flume DM - Dam at outlet or HU boundary GC - General Canal/Ditch PS - Pumping Station DD - Drainage Ditch SI - Siphon AD - Aqueduct RS - Reservoir TF - Transportation Feature (road, railroad, docks etc.) GF - Ground-Water Flow MA - Mining Activity UA - Urban Area GL - Glacier IF - Ice Field OF - Overbank Flow OT - Other Hu_10_type: Fifth Level Hydrologic Unit Type - (REQUIRED) This field was populated with the hydrologic unit type from the list provided that most closely identifies the watershed. S - "Standard" hydrologic unit - Any land HU with drainage flowing to a single outlet point, excluding non-contributing areas. This includes areas or small triangular wedges between adjacent HU's that remain after classic hydrologic units are delineated. Some examples include "true", "classic", "composite", and "remnant" hydrologic units. C - "Closed Basin" hydrologic unit - A drainage area that is 100% non-contributing. This means all surface flow is internal, no overland flow leaves the hydrologic unit through the outlet point. F - "Frontal" hydrologic unit - Areas along the coastline of lakes, oceans, bays, etc. that have more than one outlet. These HU's are predominantly land with some water areas at or near the outlet(s). 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, harbors. 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. Hu_12_ds: Sixth Level Downstream Hydrologic Unit Code - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) This field was populated with the 12-digit code of the 6th level hydrologic unit that is receiving the majority of the flow from the subwatershed. Outlets created by ditching or other artificial drainage were not considered for this field. If a HU flows into an ocean or the Gulf of Mexico it was populate 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, this field was populated with the term "CLOSED BASIN". Hu_12_name: Sixth Level Hydrologic Unit Name - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) Officially recognized names were used in this field. This field was populated by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol". The name used to attribute the subwatershed was used only once within a 4th level unit. Hu_12_mod: Sixth Level Hydrologic Unit Modifications - (REQUIRED) This field identifies any type of man-made modification(s) to natural overland flow that alters the location of the hydrologic unit boundary for a 12-digit subwatershed. One or more of the following abbreviations was chosen for this field. SC - Stormwater Canal or Drainage Canal ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal or Navigation Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Noncontributing Area KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel or Flume DM - Dam at outlet or HU boundary GC - General Canal/Ditch PS - Pumping Station DD - Drainage Ditch SI - Siphon AD - Aqueduct RS - Reservoir TF - Transportation Feature (road, railroad, docks etc.) GF - Ground-Water Flow MA - Mining Activity UA - Urban Area GL - Glacier IF - Ice Field OF - Overbank Flow OT - Other Hu_12_type: Sixth Level Hydrologic Unit Type - (REQUIRED) This field was populated with the hydrologic unit type from the list provided that most closely identifies the subwatershed.

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.

UNK - Unknown 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.
