OR Bureau of Land Management (BLM) Unpublished Material vector digital data Portland, Oregon OR BLM withheld WBD_HU12 This geospatial dataset represents the 6th level (12-digit) hydrologic unit boundaries from the Watershed Boundary Dataset (WBD) layer for Washington. Hydrologic units within the HU_BOUNDARY_WBD_WA_HUC_12 represent drainage areas delineated to the 6th 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 HU_BOUNDARY_WBD_WA_HUC_12 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 HU_BOUNDARY_WBD_WA_HUC_12 were delineated by Pacific Northwest (PNW) Hydrography Framework Partners and Natural Resources Conservation Service (NRCS) 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_12 boundaries were made from the Washington dataset that has been nationally certified 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, NRCS and the US Geological Survey (USGS). The current dataset includes all 6th level boundaries that are in all 4th level (8-digit) subbasins that fall within or intersect the Washington state boundary. 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. ftp://ftp-fc.sc.egov.usda.gov/NCGC/products/watershed/hu-standards.pdf 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. en 20090120 unknown publication date Complete Unknown -118 -116 46 44 395497.544681 468551.374681 5293591.141712 5428153.581712 None Hydrologic units Watershed Boundaries Subwatershed Boundaries Watershed Boundary Dataset ISO 19115 inlandWaters BLM-State Oregon Idaho Washington None The U.S. Department of Agriculture, Natural Resources Conservation Service, should be acknowledged as the data source in products derived from these data.

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. withheld withheld 2002 Added the following attribute fields to support the pre NRCS certification review and edit project: EDIT_TYPE - Type of edits that took place.

Portland OR 97208 USA (503) 808-6506 bmecklem@or.blm.gov 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 workarea. It was agreed by the PNW Partners and the USGS to utilize the high resolution National Hydrography Dataset (NHD) to assist with delineating hydrologic unit boundaries and locating pour points wherever possible. In these locations, the Washington WBD may deviate from the primary DRG base. The three water hydrologic units in the Columbia River (170800060500, 170800030700 & 170900120500) utilized the NHD Area and NHD Waterbody featureclasses to delineate their shorelines. It was agreed by the PNW Partners and the USGS to use the 2001 Washington State ShoreZone Inventory (szline.shp) from the Washington State Dept of Natural Resources as the coastline for the Washington WBD. This coastline extends from the mouth of the Columbia River to the north. This includes the Pacific coastline, Willapa Bay, Grays Harbor, the Strait of Juan De Fuca, the Puget Sound, and all of the islands. The Washington State ShoreZone Inventory delineates the mean high water mark and the salt water shorelines. It was agreed by the PNW Partners and the USGS to utilize the British Columbia, Canada, Watershed Atlas datasets (1:50,000 scale) to assist with delineating hydrologic units that cross the international boundary. The Washington WBD stops at the international boundary but efforts were made to match the Canadian datasets where possible. 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 met the standard was to be avoided. There were two reviews by PNW Hydrography Framework (PNWHF) stewards and NRCS stewards before a final was delivered back to PNWHF by USGS. After each review the USGS incorporated changes that were identified and agreed-upon during the review process. http://fortress.wa.gov/dnr/app1/dataweb/metadata/dnr_shorezone_metadata.htm. http://www.env.gov.bc.ca/fish/watershed_atlas_maps/index.html. 2006 Kimberly Jones USGS kjones@usgs.gov The final datasets returned from USGS were assembled to make the PNW distribution coverage and the final Washington dataset for certification. In the Final Washington 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. 20080527 Bryant Mecklem BLM Oregon State Office/Northrop Grumman GIS Specialist 503-808-6506 bmecklem@or.blm.gov Meta_ID: WA03 USGS made updates to the WBD dataset to incorporate changes submitted by the Pacific Northwest Hydrography Framework (PNWHF) partner organizations. The changes included small boundary adjustments that result in a better match with NHD. The USGS also added Water HU's and the Canadian HU's at the boarder. 20100713 Bryant Mecklem BLM OSO GIS Specialist mailing address

Portland OR 97208 USA (503) 808-6506 bmecklem@or.blm.gov Once the edits were certified the WA WBD was downloaded from the Geospatial Data Gateway and was used to make this polygon feature class. The feature class was dissolved using the fields HUC_12 and HU_12_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 6th level (12 digit) subwatershed feature class that was used to load the data into this feature class. 20110228 Bryant Mecklem BLM OSO GIS Specialist 503-808-6506 bmecklem@blm.gov Dataset copied. withheld 20110519 09114500 0 Oregon, Washington, Idaho Vector Simple FALSE 88 TRUE FALSE North American Datum of 1983 Geodetic Reference System 1980 6378137.000000 298.257222 GCS_North_American_1983 NAD_1983_UTM_Zone_11N coordinate pair meters 0.000156 0.000156 1 Explicit elevation coordinate included with horizontal coordinates wbd_hu12 Polygon Attribute Table Feature Class 88 OBJECTID Internal feature number.
