Description:
Abstract:
5th Field Watershed separated from hydro_units coverage for use in the Oregon Coastal Atlas Project.
This geospatial dataset is a hydrologic unit boundary layer that is at the Subwatershed (12-digit) level. The dataset was enveloped by delineating the boundary lines on 1:24,000 base maps and digitizing the delineated lines. Digital Elevation data may have been used in part of the process to establish preliminary boundaries.
This data set consists of geo-referenced digital map data and associated attributes. The hydrologic unit code attached to each delineated polygon is linked to the attribute data, which can contain information on area in acres, in-contributing area, state(s) the HU falls within, name for 5th and 6th level HU, 5th and 6th level code for downstream hydrologic unit, and hydrologic unit modifications. Each line has attributes that describe the HU level (1-6), originating source for that line and a metadata ID number that links the line to its associated metadata file.
Purpose:
The watershed and subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. These smaller sized hydrologic units (up to 250,000 acres) are useful in many programs supported by the REO and others.
This data set is intended as a tool for water-resource management and planning activities, particularly for site-specific and localized studies, which require the amount of detail provided by a large-scale map.
Supplemental Information:
The following procedures were used to produce this data set:
Hydrologic units were incorporated into this dataset from an aggregate of pre-existing HUs. Some new HU boundaries were delineated using flow lines and basins computed from 10- and 30-meter horizontal resolution Digital Elevation based on flow derived from the elevation grid to determine potential pour points. The DEM data is derived from hypsography represented on 1:24000 USGS topographic quadrangles. Additional hydrography data was used as a template to control pourpoint locations for the delineated HUs. This version of the data set (housed at the Oregon Geospatial Data Clearinghouse) was projected into the Oregon Lambert projection and reselected to contain only HUC's that are partially or entirely in Oregon. The acres field was widened and recomputed to allow for the width of larger HUCs. Shapefiles of the complete HUC theme and 4th-6th field HUCS were created by the Oregon Geospatial
Data Clearinghouse (OGDC) using ArcView. They represent data in the original layer.
20040226 For purposes of Oregon Coastal Atlas project this data was reprojected and clipped to basin boundaries. Please refer to originators for original data and further information regarding this data.

Use Constraints:
The Regional Ecosystem Office should be acknowledged as the data source in products derived from
these data. These data should not be used at scales greater than 1:24,000.
This is public information and may be interpreted by 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 Regional Ecosystem Office any
authority for the decisions they make. The Regional Ecosystem Office 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 cause
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.

Data Quality Information
Section Index
Attribute Accuracy:
Attribute Accuracy Report:
Polygon identifiers are manually checked with the original base map using the attribute file. Verification on
polygon identification continuity on each side of a neatline is done visually on the screen as adjacent
quad representations are assembled into larger area data layers.
Logical Consistency Report:
Certain node/geometry and topology (GT) polygon/chain relationships are
collected or generated to satisfy topological requirements. (The GT-polygon corresponds to a hydrologic
unit or a portion of a hydrologic unit at the edge of a Quadrangle sheet.) Some of these requirements
include: chains must begin and end at nodes, left and right GT-polygons are defined for each chain
element and are consistent throughout, and the chains representing the limits of the file (neatline) are free
of gaps. The tests of logical consistency are performed using vendor software. The neatline is generated
by connecting the explicitly entered four corners of the digital file. All data outside the enclosed region are
ignored and all data crossing geographically straight lines are clipped at the neatline. Neatline
straightening aligns the digitized edges of the digital data with the generated neatline (i.e., with the
longitude/latitude lines in geographic coordinates). All internal polygons are tested for closure with vendor
software and are checked on hard copy plots. All data are checked for common boundary lines (i.e.,
adjacent polygons with the same label). Quadrangles are edge matched within the Sub-basin area and
edge locations generally do not deviate from centerline more than 0.01 inches.
Completeness Report: complete
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
The accuracy of these maps is generally based on the contour information or DEM data available for the base maps. Such data
may be supplemented with site visits to locate ridge lines for hydrologic unit boundaries in flat terrain
areas, changes in drainage patterns due to man's activities. The differences in positional accuracy
between the hydrologic unit boundaries and their digitized map locations is unknown.
Hydrologic unit boundaries generally were digitized within 0.01 inches of their locations on the digitizing
source. The digital map elements are edge matched against the data for the adjacent Quadrangle. Edge
match locations generally do not deviate from centerline to centerline by more than 0.01 inches.

Hydrologic Unit Field Code- In order to identify an area, be it 1st through Nth Levels, each is assigned the combination of Levels which comprise it. Starting at the uppermost end of the drainage, the first 7th level hydrologic unit would be assigned the code 01 for the 13th and 14th digits. When combined with the 6th level code, the full Hydrologic Unit Code in the above example would be 17100203020901XX.

Hydrologic Unit Types-This item allows users to query hydrologic units based on composition type. Information is presented as a running string where each individual character of the string represents the composition type of a particular unit (e.g.- character number 1 represents the composition type of a 1st level unit, character number 2 represents the composition type of a 2nd level unit, etc). Where a hydrologic unit level has not been delineated or the type has yet to be classified, an X will serve as a placeholder. This is an optional item that may be populated for 1st through 8th level units where deemed necessary.

Enumerated Domain Value Definition:
Composite hydrologic units, or remnant areas are drainage areas typically formed as the residual areas after delineation of classic watersheds. The most common example of a remnant area is the small triangular wedge between the boundaries of adjacent hydrologic units flowing into the same side of another stream.

Overview Description:
Entity and Attribute Overview:
Hydrologic Unit delineations are closed polygons that encompass all
area draining toward the lowest point (called pour point) in the polygon. Because of nominal sizes for the
different hydrologic unit level: Watershed (40,000 to 250,000 acres) and Subwatershed (generally 10,000
to 40,000 acres), some polygons do not include all areas up to the drainage divide but all areas to one or
more other upstream hydrologic units. A unique hydrologic unit code is used to identify each hydrologic
unit. The hydrologic unit codes start with the 8-digit Sub-basin (sub-basin) number that contains the
Watershed. Likewise the Subwatershed hydrologic unit codes start with the 10-digit Watershed number
that contains the Subwatershed. Attributes associated with a hydrologic unit code includes: ACRES,
HUC_NUM, HUC_TYPE, REGION_NAME, SUBREGION_NAME, BASIN_NAME, SUBBASIN_NAME,
WATERSHED_NAME, SUBWAT_NAME, CATCHMENT_NAME, SUBCATCH_NAME, OLD_HUCNUM,
