United States Geological Survey 2003 Unknown Watersheds_Area (SGID93 Water) 1 vector digital data Fort Worth, Texas U.S. Department of Agriculture, Natural Resources Conservation Service withheld SGID.U024.Watersheds_Area This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Utah. 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. 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. en unknown ground condition Complete Unknown -114.522831 -108.649759 42.605715 36.760177 210764.600000 692863.600000 4073165.900000 4717031.600000 None HUC Hydrologic Units Hydrologic Unit Code Region Sub-region Basin Sub-basin Watershed Watershed Boundaries boundaries Subwatershed WBD Watershed Boundary Dataset Inland Water Resources None Utah USA None Data released to the Receiving Agency (RA) remains the property of the originating data source (see Source_Information) and cannot be reproduced for sale by the RA without the written consent of that data source.

Representatives from the Utah U.S. Geological Survey office, Bureau of Land Management, and Forest Service contributed a substantial amount of time and salary towards quality review of the dataset. ESRI ArcCatalog 9.2.2.1350 Feature Class 100% of the attributes were visually verified using digital raster graphics (DRGs) The accuracy of this data is dependent on the level of detail of the source material and the interprtation procedures for capturing that source. 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. 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 highest level of hydrologic unit can be determined.

Description of attributes by field from the Federal Standards for Delineation of Hydrologic Unit Boundaries 1) .pat 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. 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 ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Non-Contributing KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel DM - Dam at outlet or HU boundary OT - Other Carbonate-rock aquifers are present throughout much of Utah, particularly in the Basin and Range physiographic province. Many of the mountain ranges in this province consist in large part, of limestone and/or dolomite. Although these rocks are soluble, these areas typically receive precipitation that is less than 6 or 8 inches per year and integrated subsurface drainage systems are distinctly absent, even though isolated caves may still exist. Subbasins delineated within areas containing carbonate-rock aquifers were classified as being karst (KA) if they exhibited most or all of the following characteristics: 1) sinkholes, indicating subsurface solution 2) large springs, indicating high permeability subsurface drainage systems 3) losing streams, indicating integrated subsurface flowpaths, and 4) caves, indicating solutional development at least in the past. For purposes of delineation, only those areas that presently contain active, subsurface flow systems and have the potential for subterranean movement of water between watersheds, were designated as karst. This includes areas in the Bear River Range and Uinta Mountains of northern Utah, selected areas in the central Wasatch Range, and selected areas in the southeastern part of the state where volcanic rocks overlie limestone units. Areas that only contain caves, but do not contain any of the first three components, were not included. This includes most of the Basin and Range carbonate-rock mountain ranges. Although these areas do contain scattered caves, most were formed under geothermal conditions in the past and lie far above present-day water tables that are part of more regional (interbasin) flow systems. There are many irrigation ditches in Utah. These ditches transfer water intermittently across sub-basins. If the code ID is used in adjacent polygons, it is a likely assumption that water, on occasion, is transferred between sub-basins. The abbreviation IT was used more for aqueducts. The code OT was used to identify manmade waterbodies. Hu_10_type: Fifth Level Hydrologic Unit Type - (REQUIRED) Populate this field with the hydrologic unit type from the list provided that most closely identifies the watershed. Use any of the one-digit abbreviations in uppercase that is provided in the list. 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). 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) Populate this field 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 are not to be considered for this field. If a 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_12_name: Sixth 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". The name used to attribute the subwatershed should be used only once within a 6th level unit. Some 10-digit HU were assigned the huc_12 number when no GNIS name was identified on the DRG-Es. Hu_12_mod: Sixth 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 12-digit subwatershed. 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). If using more than one abbreviation, separate with a comma with no space after the comma. SC - Stormwater Canal ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Non-Contributing KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel DM - Dam at outlet or HU boundary OT - Other Carbonate-rock aquifers are present throughout much of Utah, particularly in the Basin and Range physiographic province.

Populate this field with the highest hydrologic unit level (smallest number) for the line (arc) represented by the record. Record the level 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 would be populated with a 1 (Region). Example two would be if a line is a subbasin, watershed, and subwatershed boundary, then the cell would get a 4 (Subbasin). Use one of the levels provided in the list below. 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 should indicate the base map source(s) used to delineate at 1:24,000 scale.

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.

The elevations used were the recognized legal lake levels, and are as follows: Great Salt Lake 4,200.00 ft., Utah Lake 4,489.34 ft., Bear Lake 5923.65 ft. There was much debate whether to use the road from Grantsville City to Wendover City (as was the case in the existing 250K old dataset), as the subdivision between 16020306 and 16020308. It was decided because we could topographically define this break, and because water is transferred many times between sub-basins under the highway, that we were justified in using this topographical subdivision.
