Description: The data layer is a composite of multiple data sources from multiple agencies. The data has been visually verified and corrected and consolidated into a common attribute structure. Jacobs staff adjusted the spatial location of each infrastructure point/polyline using aerial photo interpretation to verify that each feature occurs along an assessment stream (as applicable). Only the spatial location of infrastructure within 50 feet of an assessment stream was modified.

Description: These data are a measurement system based on the corrected streams centerlines. The river miles are set in intervals of 0.1 miles with start and stop points for each stream. The mile markers begin at the Yakima River and increase upstream. The mile markers for all streams will begin at the furthest point downstream and increase upstream.
Description: KRD Canals and Laterals from DNR orthophotos. This is a vector representation of canal centerlines. Includes all canals, laterals, and drains maintained by the KRD including Taneum Ditch, Bruton Ditch, and Turner Ditch. Piped areas are shown and will be attributed as such at a later date.
Description: These data are a corrected version of existing stream centerlines within the Naneum, Cherry, and Wilson Creeks watershed. These data will be used as the foundation layer for all work within the watershed and will continue to be refined over time. These data were digitized using ESRI-provided imagery at a 1:1200 scale. The centerlines of the streams were captured based on the imagery source and are only as accurate as the imagery. The centerlines represent a corrected version of data provided by Kittitas County.
Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.
Copyright Text: Funding for the Watershed Boundary Dataset (WBD) was provided by the USDA-NRCS, USGS and EPA along with other federal, state and local agenciesies. Representatives from many agencies contributed a substantial amount of time and salary towards quality review and updating of the dataset in order to meet the WBD Standards. Acknowledgment of the originating agencies would be appreciated in products derived from these data. See dataset specific metadata for further information
