- Abstract:
- Water Resource Inventory Areas (WRIA) for Washington State at 1:24,000
scale. WRIAs were formalized under WAC 173-500-040 and authorized under
the Water Resources Act of 1971, RCW 90.54. Ecology was given the
responsibility for the development and management of these administrative
and planning boundaries. These boundaries represent the administrative
under pinning of this agency's business activities. The original WRIA
boundary agreements and judgments were reached jointly by Washington's
natural resource agencies (Ecology, Natural Resources, Fish and Wildlife)
in 1970.
- Purpose:
- To create a WRIA coverage at a scale of 1:24,000 through the updating
of two "like" data sets from different sources. Additionally, to address
discrepancies found between the two coverages and determine a "best fit"
line through several stages of visual analysis. The development process
identified several major objectives as reasoning to update the digital
data coverage: To improve the spatial resolution of the data set, To align
the WRIA boundaries with 1:24,000 scale hydrology and topography data, To
insure of the alignment of the WRIA boundaries to existing county and
state boundaries where appropriate, and To have one reconciled set of
administrative watershed boundaries (i.e. WADNR's boundaries to nest
within the WRIA boundaries)

- Data_Quality_Information:
-
- Logical_Consistency_Report:
- Polygon and chain-node topology present. All errors incurred during
editing procedures were corrected with ArcEdit under ARC/INFO version 7.2.1
using a fuzzy tolerance of 196.8, an edit tolerance of 100.0, and a snap
tolerance of 100.0. All arc overshoots, undershoots, duplicate arcs, and arc
intersections were corrected. This resulted in a topologically clean
coverage with all arcs intersecting and snapped at nodes and each WRIA unit
comprising a single polygon.

- Horizontal_Positional_Accuracy_Report:
- Accuracy of WRIA boundary lines are a direct reflection of their
input scale, 1:24,000. The WRIA data set was derived from a base layer
of WAU units courtesy of DNR. The WAU boundaries were input at a scale
of 1:24,000 and represent accuracy standards for that scale.
Additionally WRIA boundaries were evaluated in areas of discrepancy. In
these identified areas, topographical, hydrological, and administrative
boundary information was utilized to make an informed decision about the
correct position of the boundary. All analysis decisions were made with
background images of USGS DRG 1:24,000 scale quad images to provide a
consistent and uniform framework to aid in any adjustment or editing
procedures.

- Process_Description:
- 1. Copied WAU coverage to project directory and dissolved out WRIA
polygons by WRIA_NR. 2. Overlaid WRIA100K and dissolved WAU coverage to
create discrepancy polygons. 3. Created point discrepancy coverage. 4.
Applied selection criteria (polys > 35 acres, points > 750 feet) to
discrepancy coverages. 5. Intersected 24K quadrangle and
section-township-range coverage with polygon and point discrepancy
coverages. 6. Attached attributes of intersected coverages and performed
ranking procedure to prioritize the results. 7. Mapped each polygon
discrepancy by quadrangle and grouped each map by its associated WRIA
basin. 8. All WRIA maps were assembled into books representing each WRIA
and its discrepancies. 9. Microsoft Access database developed to help
manage and report project data (editing, analysis decisions, comments).
10. Visual analysis of each discrepancy performed using the map books
(stage 1). 11. Additional analysis performed using USGS DRGs at 1:24,000
scale as well as, in house hydrology and administrative boundary data
sets (stage 2). 12. Project edits carried out based on the two stages of
analysis.
The project was revisited in March of 2000 using two additional
methods of analysis. First, the WRIA24K boundaries were overlaid with
statewide 24K scale hydrology coverage to check for stream crossings. A
10 foot buffer was used on either side of the WRIA boundary to limit the
size of the output data set. Stream crossings were then evaluated for
relevance. Additionally, a general overview of the WRIA boundaries as
done by examining each WRIA again the 24K scale USGS DRGs. This was done
as an additional check for unnecessary stream crossings and drainage
errors.
