These polygons are not intended to represent the Ordinary High Water (OHW). Rather, these polygons are intended to assist professionals in their determination of OHW based on field evidence and to be used in analysis for planning purposes. The waterbody polygons represent a static snapshot in time based on the best available information—most waterbodies vary with seasonal and climatic changes.Thurston County Hydro/Stream data originated as coverage file representation of the Thurston County hydro network. It included all waterbodies: rivers, lakes, ponds, inlets and streams. The features were digitized by the Thurston GeoData Center from the Thurston Comap, Assessor's Data dated 1990, and Tiger Files using rubber sheeting and aerial digitizing. In 2002-2003 the data was updated along Marine Shorelines using updated Aerial Photography. In 2011 the hydro coverage file was converted into a feature class file, during which process stream and river data was separated from other waterbodies; large river areas, lakes, ponds, and marine areas. The datasets were renamed to Streams and Waterbodies respectively. In 2014 some minor adjustments were made to both layers in the Lake Lawrence area as the result of LiDAR derived hydro enforced DEM data.In 2021 approximately 40 of the larger lakes were updated using 2017 LiDAR and 2011 LiDAR to be included in the pending Shoreline Master Program (SMP) update. The purpose of this data is to display all water bodies in Thurston County. This layer is used primarily as a reference however it is also used to represent waterbodies in analysis completed by the county. These polygons are not intended to represent the Ordinary High Water (OHW) of lakes.
