Abstract:
Water bodies (lakes, wetlands, etc.) published in Chapter 173-20 WAC. These will be replaced by water body lists published in local government shoreline master programs. See Chapter 173-20-044 WAC.
Purpose:
Provide a layer of the lakes under Shoreline Management Act jurisdiction as listed in WAC 173-20. This data is being continuously outdated. See WAC 173-20-044 posted at <http://apps.leg.wa.gov/wac/default.aspx?cite=173-20&full=true#173-20-044>
Supplemental_Information:
(1) Washington state is divided into two State Plane Zones, north and south. For this data set, north zone data coordinates have been converted to south zone coordinates.
(2) Time period of content was derived from an estimated range of publication dates from USGS 1:24,000 scale quadrangles encompassing the state of Washington (from which base data were originally compiled). Specific publication dates should be referenced from individual quadrangles.
(3) The dataset is a product of the Pacific Northwest Hydrography Framework Clearinghouse process. It integrates the best available hydrographic data from the WA Dept of Natural Resources, U.S. Forest Service, and U.S. Bureau of Land Management.
(4) The WA Dept of Ecology performed the integration of the data from the Hydrography Framework partners. The integration work was conducted between January 2005 and March 2006.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Data attributes values are created and updated within the context of rigorous editing routines. Values are checked for validity within a group of specific ranges or within specific sets of codes. Attribute accuracy of data within the initial phase was tested by manually comparing digital products to the source maps.
Logical_Consistency_Report:
Specified spatial processing tolerances are used to snap arc over-shoots to proximal nodes. Remaining anomalous objects falling outside of specified tolerances are flagged by the software and manually corrected for logical consistency.
Completeness_Report:
Spatial completeness: Statewide coverage. Data Attribute Completeness: Complete.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of this dataset is based upon the use of USGS source quadrangles which are compiled to meet National Map Accuracy Standards. NMAS horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position (on the map). The digital data are estimated to contain a horizontal positional error of less than or equal to 0.003 inches standard error in the two component directions relative to the source quadrangle. Comparison to the graphic source is used as control to assess digital positional accuracy. Cartographic offsets may be present on the graphic source, due to scale and legibility y constraints.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical positional accuracy is based upon the use of USGS source quadrangles which are compiled to meet NMAS. NMAS vertical accuracy requires that at least 90 percent of well defined points tested be within one half contour interval of the correct value. Comparison to the graphic source is used as control to assess digital positional accuracy. The file has undergone digital revision. Accuracy of the digital data meets the class 1 positional accuracy specifications in the draft United States National Cartographic Standards for Spatial Accuracy.

Process_Description:
This Digital Line Graph was digitized from the USGS source quadrangle, by either the National Mapping Division, one of their cooperators, or one of their contractors. The digital data were produced by on of the following methods. -scanning a stable-based copy of the graphic materials. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. - scanning the paper map. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. -scanning a stable-based copy of the graphic materials. The resulting raster data were then manually digitized and attributed on an interactive editing station. The resolution of the digital data is at least 0.001 inches. -scanning the paper map. The resulting raster data were then manually digitized and attributed on an interactive editing station. The resolution of the digital data is at least 0.001 inches. -manually digitizing from a stable-based copy of the graphic material using a digitizing table to capture the digital data at a resolution of at least 0.001 inches; attribution was performed either as the data were digitized, or on an interactive edit station after the digitizing was completed. -manually digitizing from the paper map using a digitizing table to capture the digital data at a resolution of at least 0.001 inches; attribution was performed either as the data were digitized, or on an interactive edit station after the digitizing was completed. The determination of the DLG production method was based on various criteria, including feature density, feature symbology, and availability of production systems. Four control points corresponding to the four corners of the quadrangle were used for registration during data collection. AN eight parameter projective transformation was performed on the coordinates used in the data collection and editing systems to register the digital data to the internal coordinates used in PROSYS, and a four parameter linear transformation was performed from the PROSYS internal coordinates to Universal Transverse Mercator (UTM) grid coordinates. The e DLG data were checked for position by one of the following processes: -comparing plots of the digital data to the graphic source. - comparing the digital data to the digital raster scan. DLG data classification was checked by at least one of the following processes. - comparing plots of the digital data to the graphic source. - comparing the digital data to the digital raster scan.

Process_Description:
The Pacific Northwest Hydrography Framework water body coverages were constructed from the polygon features representing areal hydrographic features, including lakes, wetlands, glaciers, oceans, estuaries, and streams represented by double banks. Enhancements made were the editing of polygon attributes for water body type code and geographic feature name, and the creation of a unique identifier based on the latitude/longitude of the water body centroid.
The framework processing procedures were:
1) verifying the DLG water body type codes for each polygon and converting that value to the WB_CART_FTR_CD attribute.
2) assigning the GNIS feature name to water body polygons in the WB_GNIS_NM attribute and WB_GNIS_NR attribute.
3) assigning a unique Lat/Long identifier to each water body polygon (including islands) If the water body was represented in the 100K Water Body layer, that LLID was used.
4) assigning an appropriate value to the WB_HYDR_FTR_CD attribute.

Process_Description:
The ArcInfo water body coverages were converted into a single ArcSDE polygon feature class inside a 24K Hydrography feature dataset.
1) Create a 24K Hydrography feature dataset.
2) Add water body subtypes and domain values to the feature dataset.
3) Create an empty water_body feature class inside the feature dataset.
4) Load the vector water body data into the feature class using the ArcCatalog 9.1 Simple Data Loader. The source data was the 62 water body coverage polygons (one coverage for each WRIA).
