Abstract: As established by WAC 222-22-020, the state is divided into areas known as watershed administrative units (WAUs). WAU boundaries are defined by the Department of Natural Resources (DNR) in cooperation with the departments of Ecology, Fish and Wildlife, affected Indian tribes, local governments, forest land owners, and the public. This dataset is intended for use at 1:24,000 scale. WAU's are used by the Timber/Fish/Wildlife cooperators as the boundaries for watershed analysis studies and other natural resources management purposes on state and privately owned lands. WAU represents the administrative boundaries of 846 units. The boundaries are mainly along drainage divides (ridges), with some along rivers and other Washington State Department of Natural Resources (DNR) management boundaries. In the forested areas of the state WAUs range in size from 3,822 to 297,614 acres with a mean of 40,187 acres and a standard deviation of 26,697 acres. On the Columbia Plateau WAU areas range in size from 35,098 to 1,765,555 acres. This version of the WAU boundaries is current as of April 2006. Administrative boundaries based on hydrology form a general hierarchy. Water Resource Inventory Areas (WRIAs) are the largest unit, BASINs are subunits of WRIAs, and WAUs are subunits of BASINs. However, boundaries in this hierarchy do not necessarliy match in all areas. Where watershed analysis was been conducted, WAU boundaries may cross WRIA lines. Do not use WAU to derive WRIA boundaries. WRIA is managed and maintained by the Washington Department of Ecology.

FGDC and ESRI Metadata:

Abstract:
As established by WAC 222-22-020, the state is divided into areas known as watershed administrative units (WAUs). WAU boundaries are defined by the Department of Natural Resources (DNR) in cooperation with the departments of Ecology, Fish and Wildlife, affected Indian tribes, local governments, forest land owners, and the public. This dataset is intended for use at 1:24,000 scale. WAU's are used by the Timber/Fish/Wildlife cooperators as the boundaries for watershed analysis studies and other natural resources management purposes on state and privately owned lands.   

WAU represents the administrative boundaries of 846 units. The boundaries are mainly along drainage divides (ridges), with some along rivers and other Washington State Department of Natural Resources (DNR) management boundaries. In the forested areas of the state WAUs range in size from 3,822 to 297,614 acres with a mean of 40,187 acres and a standard deviation of 26,697 acres. On the Columbia Plateau WAU areas range in size from 35,098 to 1,765,555 acres. 

This version of the WAU boundaries is current as of April 2006.  

Administrative boundaries based on hydrology form a general hierarchy. Water Resource Inventory Areas (WRIAs) are the largest unit, BASINs are subunits of WRIAs, and WAUs are subunits of BASINs. However, boundaries in this hierarchy do not necessarliy match in all areas.  Where watershed analysis was been conducted, WAU boundaries may cross WRIA lines.  Do not use WAU to derive WRIA boundaries. WRIA is managed and maintained by the Washington Department of Ecology.

Purpose:
WAU's are used by the DNR for watershed analysis and other natural resources management purposes on state and privately owned lands.

Supplemental information:
WAUs are administrative boundaries. For a more true watershed boundary use the federal Water Boundary Dataset at http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/

Data Quality Information:


Logical consistency report:
Polygon and chain-node topology present. All errors incured during editing procedures were corrected with ArcEdit under ARC/INFO version 8.x using a fuzzy tolerance of .581, an edit tolerance of 100, node snap of 20, weed of 40, grain of 40, and a snap tolerance of 40. All arc overshoots, undershoots, duplicate arcs, and arc intersections were corrected.  The resulting WAU coverage is topologically clean.

Completeness report:
Data set is complete

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Administrative boundaries based on hydrology form a general hierarchy. Water Resource Inventory Areas (WRIAs) are the largest unit, BASINs are subunits of WRIAs, and WAUs are subunits of BASINs.  The WRIA coverage was compiled by the Department of Ecology at a scale of 1:24,000; additional WRIABASIN arcs and WAU arcs were digitized at 1:24,000 scale by DNR Forest Practices Division. The WRIA's were originally subdivided into Basins by digitizing at a scale of 1:250,000; and these basins were later subdivided into WAU's by digitizing at 1:100,000.  WRIA, Basin, and WAU lines were refined to 1:24,000 as stated above in 1998 and 2000.

Boundaries in this hierarchy do not necessarliy match in all areas. Do not use WAU to derive WRIA boundaries.

Process description:
PROCESSING PROCEDURES: Ridge lines and hydrologic basins delineated and digitized from USGS 7.5' quadrangles by DNR Forest Practices Division personnel.  Watershed analysis staff delineated correct hydrologic basin boundaries. PROCESSING TOLERANCES: Fuzzy = .581; Dangle = 0; Weed = 40; Grain = 40; Snap = 40; Nodesnap = 20; Edit = 100  HISTORY OF CHANGES TO DATA SET: Original data set compilation was completed in 1993.  Water Resource Inventory Areas (WRIA) boundaries were compiled by Information Technology Division staff at 1:24,000 scale.  Additional Basins subdividing WRIAs were digitized at a scale of 1:250,000 by DNR Forest Practices personnel.  Additional Watershed Administrative Units (WAU) were digitized at a scale of 1:100,000 by DNR Regional personnel.  Subsequently, WAU boundaries were updated at a scale of 1:24,000 when a watershed analysis was initiated.   Most recently, WA DNR Forest Practices watershed analysis scientists, lead by Matt Brunengo, have delineated all remaining WAU boundaries to 1:24,000 scale.  These boundaries were digitized by DNR Forest Practices cartographers, lead by Liz Thompson and Tom Boyd. In 2000, new WRIA boundaries, completed by the Department of Ecology, at 1:24,000 scale were incorporated into the coverage. The April 2006 WAU revision consolidates all 1:24,000 scale improvements, conforms to 1:24,000 scale statewide, and incorporates the federal fifth and sixth level hydrologic units revised within the past two years.

Overview description:
Dataset overview:
As established by WAC 222-22-020, the state is divided into areas known as watershed administrative units (WAUs). WAU boundaries are defined by the Department of Natural Resources (DNR) in cooperation with the departments of Ecology, Fish and Wildlife, affected Indian tribes, local governments, forest land owners, and the public. This dataset is intended for use at 1:24,000 scale. WAU's are used by the Timber/Fish/Wildlife cooperators as the boundaries for watershed analysis studies and other natural resources management purposes on state and privately owned lands. WAU represents the administrative boundaries of 844 units.
