The Washington State Department of Ecology has defined a facility/site as an operation at a fixed location that is of interest to the agency because it has an active or potential impact upon the environment. Ecology recognizes that this definition is broad and generic; but the agency has found that such a definition is required in order to encompass all the facilities and sites in Washington that are within the purview of its programs. These programs cover a wide variety of environmental aspects and conditions including air quality, water quality, shorelands, water resources, toxics cleanup, hazardous waste, toxics reduction, and nuclear waste. The definitions of a facility and/or a site vary significantly across these programs, both in practice and law. Examples of facilities/sites include: operation that pollutes the air or water, spill cleanup site, hazardous waste management facility, hazardous waste generator, licensed laboratory, SUPERFUND site, farm which draws water from a well, solid waste recycling center, etc.
The Environmental Information Management System (EIM) is the Department of Ecology's main database for environmental monitoring data. EIM contains records on physical, chemical, and biological analyses and measurements. Supplementary information about the data (metadata) is also stored, including information about environmental studies, monitoring locations, and data quality. Data in EIM is collected by Ecology or on behalf of Ecology by environmental contractors - and by Ecology grant recipients, local governments, and volunteers. EIM Locations is a point feature service representing the monitoring locations from EIM. The locations consist of both surface locations for monitoring air, water, and habitat and wells for monitoring ground water. This feature service queries directly the EIM publication database which is updated nightly from the production transactional database.
This GIS layer contains bathymetric elevation bands (derived from bathymetric contours) of selected freshwater lakes in Washington State. The majority of the bathymetric contours were digitized from maps contained in a series of seven documents: Reconnaissance Data on Lakes in Washington, Water-Supply Bulletin 43, Volume 1 through 7 by the United States Geological Survey in cooperation with the Washington State Department of Ecology. The exceptions are 1) Lake Chelan which was digitized in 2016 from the publication Morphometry of Lake Chelan (published in January 1987); 2) Lake Sammamish whose digital data was acquired from King County in 2013 and is derived from data collected during the publication of Development of a Three-Dimensional Hydrographic Model of Lake Sammamish (published in November 2008); and 3) Lake Crescent, whose digital bathymetric soundings were taken by a private party during 2013/2014 and provided to the Department of Ecology and were converted to contour lines in 2016.

The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types. See http://geonames.usgs.gov for additional information.
The Washington State Department of Ecology has four regions covering the state: Eastern, Central, Northwest, and Southwest. Boundaries between the regions follow county boundaries. Regional offices are located in Spokane (Eastern), Yakima (Central), Bellevue (Northwest), and Olympia (Southwest).
The Washington State Land Use coverage was produced from digital county tax parcel layers using Department of Revenue (DOR) two digit land use codes (see; WAC 458-53-030, Stratification of assessment rolls - real property). Land use attribute data has been normalized for all county parcel data to conform to the two digit DOR codes. All county parcel layers are dissolved using the normalized land use code. No county parcel information remains in this data other that what geometry remains from the dissolve process.
The Tri-County (Asotin, Garfield and Whitman) Land Use coverage was digitized from 2006-2009 Orthophoto imagery and Google Streetview. Public land ownership boundaries were overlaid using Major Public Lands (MPL) and DNR Managed Lands (CADASTRE.PARCEL). Cultivated agriculture lands were added using USGS LULC for Asotin and Whitman Counties and SSURGO Farm Soils for Garfield County. Land use attribute data has been normalized for all county parcel data to conform to the two digit Department of Revenue (DOR) codes. This is a draft land use dataset and is not parcel based.
Ecology created the GIS statewide river mile point layer in March 2007 by digitizing the river mile points depicted on the USGS 7½ minute (24k) topographic quadrangle maps. Some of the rivers have gaps in the river mile progression because several of the quadrangle maps do not have any river mile points, while a few were missing a point or two. In November 2014 Ecology added river mile points for the missing areas using Washington Department of Fish and Wildlife's (WDFW) 1975 Stream Catalog, which only covers WRIA's 1 through 24. The Stream Catalog shows river miles for nearly every stream; however, only those water courses that have river miles from the USGS quadrangle maps were added. The field SOURCE denotes the source of the data point, USGS or WDFW. Discrepancies between the USGS and WDFW are documented in the Supplemental Information section.
This dataset describes Tribal Lands in Washington State. Included are areas where the tribes ceded title to their historic areas of use to the U.S. Government through various treaties enacted during the later half of the 19th century. Boundary lines have been digitized from a variety of digital data sources including 1:100,000 streams for boundaries described in treaties as following a stream or river, 1:24k Water Resource Inventory Areas (WRIA), Watershed Administrative Unit (WAU) and Hydrologic Unit Code (HUC) boundaries for boundaries referred to in treaties as 'divide', 'summit' or 'between the waters of', 1:100,000 Major Public Lands (for current reservation areas), 10 meter DEM and 7.5 minute USGS digital Quad maps (to define ridgelines and 'divide' where WRIA, WAU or HUC boundaries don't exist) and NAIP orthophoto imagery (to get a feel for what a questionable boundary area actually looks like today). Ceded Land treaty areas are based on treaty language and US Government decrees dated 1854-1892. Natural geographic barriers such as streams and ridge lines were used where described or eluded to in treaty descriptions. Coordinate based latitude/longitude boundary lines were used in some Central Washington areas where described. References to general compass directions were followed using natural barriers such as watershed boundaries or drainages wherever possible. Some treaty boundary descriptions were found to be inadequate, inaccurate and in some cases misleading in nature in describing what should have been a natural boundary or even a coordinate based solution to a property description. Some of these boundary areas open to interpretation are discussed below in the Supplemental Information based on the language and definite boundaries of other treaty areas. Ceded areas in Oregon and Idaho from the Camp Stevens Treaties have been included in this dataset. The Washington State Department of Ecology makes no warranty for the accuracy of this material and is not libel for its use. Ecology will maintain this data layer for its own use and distribute to all interested parties. Updates, corrections and documentation should be submitted to the contact person. This data may or may not reflect the most current tribal reservation areas. Tribal reservations are updated regularly in the Major Public Lands (MPL) layer maintained by Washington State Department of Natural Resources. This GIS data is draft information and a work in progress and should be used only as a generalized visual guide to 150 year old treaties of limited content.
Water Resource Inventory Areas (WRIA) for Washington State at 1:24,000 scale. WRIAs were formalized under WAC 173-500-040 and authorized under the Water Resources Act of 1971, RCW 90.54. Ecology was given the responsibility for the development and management of these administrative and planning boundaries. These boundaries represent the administrative under pinning of this agency's business activities. The original WRIA boundary agreements and judgments were reached jointly by Washington's natural resource agencies (Ecology, Natural Resources, Fish and Wildlife) in 1970.
