Abstract:
This geospatial dataset represents the 5th level (10-digit) hydrologic unit boundaries from the Watershed Boundary Dataset (WBD) layer for Oregon. Hydrologic units within the WBD_OR_HUC_10 represent drainage areas delineated to the 5th level drainage systems. Their boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surface waters. Hydrologic units within the WBD_OR_HUC_10 can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points.

Boundaries within the WBD_OR_HUC_10 were delineated by Pacific Northwest (PNW) Hydrography Framework Partners to meet state requirements and to contribute to the national WBD repository. To meet these goals, the WBD must adhere to the "Federal Standards for Delineation of Hydrologic Unit Boundaries", dated October, 2004.

These HUC_10 boundaries were made from the Oregon dataset that has been given national certification by Natural Resources Conservation Service (NRCS) Prior to submission the dataset was subjected to an iterative review and edit process to ensure that the hydrologic boundaries fully satisfy the federal standards. This work was completed under a Memorandum of Understanding between the Pacific Northwest Hydrography Framework Partnership and the US Geological Survey (USGS). The current dataset includes 5th level boundaries that are in all 4th level (8-digit) subbasins that fall within or intersect the Oregon state boundary.

Purpose:
This dataset was created to meet both national and regional requirements. It satisfies the national requirement for a seamless hydrologic unit boundary dataset for the nation that is developed at the 1;24,000 scale. Regionally, the dataset will be used for a number of specific purposes including resource management planning, watershed analysis, National Environmental Policy Act (NEPA) cumulative effects analysis, Endangered Species Act (ESA) consultation, biological assessments, water quality restoration plans, water temperature assessments, watershed council project support, etc.

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 NRCS and others.

Use_Constraints:
The U.S. Department of Agriculture, Natural Resources Conservation Service, 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 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 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.

Process_Description:
PNW Hydrography Framework (PNWHF) Partner agencies originally delineated hydrologic unit boundaries to meet specific agency requirements.

The PNWHF Partnership initiated a workshop-oriented process whereby agreed-upon hydrologic boundaries were accepted or delineated using 1:24,000 scale Digital Raster Graphics. A number of new Hydrological Unit Boundaries were also delineated using flow lines and basins computed from 10- and 30-meter horizontal resolution Digital Elevation data based on flow derived from the elevation grid to determine potential pour points. This workshop process resulted in a seamless hydrologic boundary dataset for Oregon.

The PNWHF dataset was made available via its website for operational edits. PNWHF Partners downloaded the dataset, edited boundaries and attribution, and submitted the updated dataset back to the PNWHF server.

The dataset was frozen prior to submittal to the review and edit process, the precursor to NRCS certification.

The Pacific Northwest HU boundary dataset was broken up into workareas and provided to USGS from 1 (PNW1) through 15 (PNW15) according to a schedule defined by all PNW partners and USGS. The PNW#'s were extracted and sent to the USGS for update and edit as a precursor to national NRCS certification.

Process_Step:
Process_Description:
USGS refined the PNWHF Hydrologic Unit Boundaries and required attribution using consistent, reproducible methods that meet the "Federal Standards for Delineations of Hydrologic Unit Boundaries". It was agreed that the Digital Raster Graphic (DRG) would be the primary source used for delineating boundaries. Arc, polygon and attribute adjustments were made to each PNW#. Changes were limited in the dataset to only those modifications that were needed to meet the national guidelines. Replacement of boundary lines or HU names that already meet the standard were to be avoided. There were two reviews by PNW Hydrography Framework (PNWHF) before a final was delivered back to PNWHF by USGS. After each review USGS incorporated changes that were identified and agreed-upon during the review process.

The final datasets returned from USGS were assembled to make the PNW distribution coverage and the final Oregon dataset for certification. In the Final Oregon Dataset attributes fields were updated to to meet the national standards for both Arcs and Polgons. All Seventh field huc attributes, Arcs and labels were deleted from this final dataset.

Process_Description:
The final publication coverage wbd_ore was used to make this polygon feature class. The coverage was dissolved using the fields HUC_10 and HU_10_NAME also using the sum of Acres in the statistics field to get the acres for each polygon. The output from the dissolve comand is a 5th level (10 digit) watershed shapefile which was used to load the data into this feature class.

The WBD_Oregon coverage contains attributes for polygons and arcs. 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 (huc_8) number that contains the Watershed. Likewise the Subwatershed hydrologic unit codes (huc_12) start with the 10-digit Watershed number (huc_10) that contains the Subwatershed. Attributes associated with a hydrologic unit code includes: ACRES, HUC_10_TYPE, HUC_12_TYPE, HUC_10_MOD, HUC_12_MOD, , HU_8_NAME, HU_10_NAME, HU_12_NAME, STATES, NCONTRB_A, HU_10_DS, HU_12_DS, HUC_MOD, COMMENT, HUC_8, HUC_10, HUC_12, HU_10_GNIS_NUM, HU_12_GNIS_NUM, HUC_LEVEL, LINESOURCE, LINEVER, LINEDATE, LINEORG, META_ID, COMMENT.
