GIS Data

Ecology maintains the spatial datasets described here in order to better describe the diverse natural and cultural environment that we live and work in. As a public service, we have made some of our data available for viewing and downloading here.


Ecology's Spatial Datasets

Our spatial datasets are available as zipped shapefiles or geodatabases (unless otherwise noted), our metadata files are in FGDC format, and our view files are in JPG format. Ecology's standard projection and datum for our shapefiles is Washington State Plane, South Zone, NAD 83 HARN, units US feet, unless otherwise noted. If you are using NAD 27 and want to reproject our data to that standard, please see our FAQ question. (More information on our data standards.)

If you can't find the data that you are seeking here, please check our links to other websites at the bottom of this page. Please use our Digital Data Request Form (view HTML format) to order data (if you are unable to download it here).

We also have maps available. For a listing of these maps, please go to our GIS Maps page.

Having problems using our data? Our Frequently Asked Questions (FAQ) and Help Page may have the answer.


GIS DATA CONDITIONS OF USE

Please note that our GIS data, while available for free of charge, is covered by Ecology's Conditions of Use Statement. Please view the conditions on the Site Information Page http://www.ecy.wa.gov/siteinfo.html.

Shoreline Management Act (SMA) - SMA Jurisdiction Adopted

Streams, rivers, lakes, swamps and marine areas designated "Shorelines of the State" or “Shorelines of Statewide Significance” by local governments and published in their shoreline master program and adopted by Ecology. These data represent the current shoreline Management Act jurisdiction as of June 2015. These features are mapped to the WA State Standard NHD Hydrography layer (version February 2015) and can be used as linear events.

This geodatabase contains three feature classes:

  • SMA_Jurisdiction_Lakes (polygons)
  • SMA_ Jurisdiction _Streams (arcs)
  • SMA_Jurisdiction_Marine

Shoreline Management Act (SMA) - SMA Jurisdiction Original (will not be updated)

Features that were originally published in Chapter 173-18 and Chapter 173-20 WAC. These features WILL BE SUPERSEDED by SMA_Jurisdiction_Adopted as local government updates are approved by Ecology. This layer is slowly becoming outdated as cities and counties update their list of Shoreline Management Act streams in their shoreline master program. See WAC 173-18-044 posted at http://apps.leg.wa.gov/wac/default.aspx?cite=173-18-044.

This geodatabase contains three feature classes:

  • WAC173_18_Arcs (Streams and Rivers)
  • WAC173-18_Points (Points on streams and rivers where shoreline jurisdiction begins and where streams and rivers cross county boundaries)
  • WAC173_20_Polygons (Lakes and Wetlands)
3,067

Shoreline Management Act (SMA) - SMA Jurisdiction Suggested (will not be updated)

Features that were estimated to qualify as “Shorelines of the State” and “Shorelines of Statewide Significance” as defined in the Shoreline Management Act, Chapter RCW 90.58.030 RCW. For use by local governments when updating their shoreline master program. These features WILL BE SUPERSEDED by SMA_Jurisdiction_Adopted as local government updates are approved by Ecology.

This geodatabase contains three feature classes:

  • SMA_Pnts_Sugg (estimated jurisdictional flow points on streams and rivers likely to qualify as "shorelines" and "Shorelines of Statewide Significance)
  • SMA_Arcs_Sugg (streams and rivers estimated to qualify as "Shorelines of the State" based on their flow)
  • SMA_Poly_Sugg (water bodies lakes, wetlands, etc. estimated to qualify as "Shorelines of the State" based on their area), http://www.ecy.wa.gov/programs/sea/sma/st_guide/jurisdiction/index.html

Surface Water Quality Standards for the State of Washington

This dataset contains spatial and attribute information of the Surface Water Quality Standards for the State of Washington, Chapter 173-201A WAC. Four views of the WQ Standard are contained in this dataset, Freshwater Beneficial Uses, Seasonal Supplemental Spawning and Egg Incubation Temperature Standards, rules designated in Table 602, and exceptions to Table 602 listed in the footnotes.  If any discrepancies are found between GIS layers and the published rule, the published rule takes precedence.
