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) |

| description:
|
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. |
