Service Description: Mapping of Visible Surface Water (VSW), or water features not shaded by tree canopy, is important in monitoring long-term environmental changes. In the process of evaluating existing hydrology datasets, including the National Hydrography Dataset (NHD) and the WDFW Statewide Washington Integrated Fish Distribution (SWIFD), we began mapping visible surface water throughout Puget Sound in Summer 2019. This work has since been expanded to include other areas throughout the state. It will be updated as new visible surface water data is created for other counties and WRIAs.

Subject: This dataset includes visible surface water in Washington State. Visible surface water includes any water body visible in NAIP imagery, but does not include portions of features covered by tree canopy. Water bodies (lakes, rivers, wetlands, etc.) are represented as polygons and include attributes on the type of water body, year of verification, and data source. This datasets only includes features for most of Western Washington and several counties in Eastern Washington. Most of the data was generated using 2017 imagery, but areas of data generated from 2011, 2013, or 2015 imagery also occur.
