Summary
Cartographic and analysis of anthropic and natural open water features.
The layer contains a RATE item which is set to CURRENT for this edition, indicating that only the most current (non-historic) water features are shown.
Historic (changed) waterbody information can be found in WTRBDY_DET_AREA
Description
Open water features, both natural and anthropic, for King County and portions of adjacent counties.
Features can be displayed as water or non water to distinguished between water and land.
FEAT_TYPE item defines multiple classes of features, primarily lakes/ponds and streams rivers.
Puget Sound and significant double-banked streams and rivers are shown, plus a limited number of manmade features such as aqueducts, ditches, channels and flumes.
Areal open water features are mainly differentiated as either Lakes/Ponds or Impoundments roughly defined as natural and anthropic, respectively.
The name of features, where available, is included.
By using the SUBSET item the layer can be defined to show only the larger water bodies and rivers.

| Supplemental Information |
Previous editions of this layer also produced a separate BIGWATER layer where the major feature subset was created as a permanent layer. This is no longer created. King County shapefile users can perform a definition query on the SUBSET item, or depend on the WTRBDY_AREA_BIGWATER.AVL legend. Geodatabase featureclass users can also perform a definition query, but may also use the WTRBDY_AREA_BIGWATER.LYR file found in the Plibrary LYR library. Overlapping and some multipart geometry has been removed from this version of WTRBDY in order to simplify its use and display. 1. The tidal line (high-low tide) has been removed from Puget Sound. This information is still available in WTRBDY_DET_AREA.2. Marine islands have been removed completely. If needed these can be found in WASHSH_AREA or KINGSH_AREA which are re-derived each time WTRBDY_AREA is updated. 3. Fresh-water islands are erased from double-banked streams allowing the position of the islands to be determined and for underlying topography to show through. This eliminates the occasions where the islands were previously hidden due to overlapping geometry. Fresh-water islands can still be displayed by querying for this feature type in WTRBDY_DET_AREA or by using the customized LYR file called WTRBDY_DET_AREA_ISLANDS.lyr4. Feature type 406 (Dam, wier, or obscured) that overlap water are also erased. This eliminates some unintentional hidden affects, but primarily improves the display along built-up harbor areas. With these features erased from the water, the fit between current orthoimagery and the egde of water is better. This feature type can also be found in the the ISLANDS customized LYR file described above. The overall intent of these changes is to remove man-made and land features from WTRBDY_AREA to increase the emphasis of this layer as water-only. |

Change history
| 9/12/2016 |
Updated using 2015 Aerial photography for the west side of the county and 2015 pictometry for the east side of the county. |
| 5/1/2011 |
Updated WTRBDY by 2010 ortho imagery. Also compared data from Covington with KC WTRBDY for updates. At same time updating WTRCRS so that WTRBDY aligns with WTRCRS. |
| 10/8/2009 |
Rate = BAD features were removed. These BAD features were features originally coded as waterbodies prior to the 2007 imagery update. Reviewing against the 2007 imagery indicated that these features are not valid waterbodies. Editors are instructed not to remove feature during review, but to code RATE = BAD. The BAD features were written to a shapefile in the SupportingData folder in the workspace. |
| 9/1/2009 |
Misspelling for 'South Fork Snoqualmie River' fixed. Misspelling for Hanson Reservoir corrected. |
| 9/26/2008 |
Lake Garrett (in Lakewood Park in White Center) is renamed Hicks Lake. This is based on input from the public, internal usage, and USGS GNIS reference. The lake still maintains the alternate name of Lake Garrett. |
| 4/1/2008 |
CHANGE IN GEOMETRY MODEL FOR PUBLISHED SDW VERSION: Prior to publication of user version to Spatial Data Warehouse the following geometry revisions are made programatically. 1. Freshwater islands are erased from underlying double-banked stream geometry 2. Manmade over-water features (Dams, wiers, docks, etc) are erased from the underlying waterbody. |
| 4/1/2008 |
CHANGE IN PRIMARY GEOMETRY MODEL: Marine island polygons (those in Puget Sound, including Vashon), and Mercer Island polygon were permanently removed. The tide line in Puget Sound has been removed. |
| 4/1/2008 |
The existing version of WTRBDY depended on Geodatabase Coded Value Domains (CVDs). These relate a stored integer value to a look-up value in the CVD. To make the resulting SDW featureclass and shapefile appear similar and to ensure that attribute value persist even when changes to the look-up value of the CVD changes, the information in the CVDs is hardcoded into the schema of the version of WTRBDY_AREA posted to the SDW. This required addition of the following items: STATUS_CD - Integer value for STATUS item WATER_CD - Integer value for WATER item SUBSET_CD - Integer value for SUBSET item TYPE_CD - Integer value for FEAT_TYPE item SOURCE_CD - Integer value for SOURCE item. |
| 7/10/2007 |
General maintenance items based on user feedback. - Angel Lake renamed Angle Lake - Howard Hansen Reservoir was incorrectly labeled Chester Morse Lake. Corrected. - A small slough north of Mercer Slough Nature Park was edited so that the land between the two branches of the slough appears as non-water rather than an island. |
| 7/1/2007 |
Updates using 2007 (July-August) Pictometry Orthoimagery begun. Per editing rules outlined in DataSet Overview, this imagery was used to check and update all features within the imagery project area. New features added and source code updated. Boundaries of existing features are edited if adjustment required is minor; otherwise existing feature is moved to OLD status and new feature created. For all features, reviewed and/or edited, the source code was updated to reflect 2007 review. See Project Plan for additional details. Columns AA thru AN were completed at the start of the update. Three additional editors were assigned areas east of Column AN to assist in completing review of WTRBDY_AREA against the 2007 imagery. They worked on aerial waterbodies only, double-banked streams and edge-of-water (Puget Sound) are being handled separately. |

WTRBDY was created in a 1997 joint project between WA Dept of Ecology and King County Water and Land Division from an initial source coverage of the standard WA Dept. of Natural Resources hydrography layer. This data set is integrated from numerous sources, primarily at 1:24,000 scale. More information about this initial version, some of which still applies to the current version, can be found in this supplemental document. Beginning in 2001, WLRD started updating this coverage with additional information from other jurisdictions and field data. |
