Tools to View Water Quality Listings

 

The Water Quality Assessment lists waterbody segments that have water quality data available in 5 different categories.

To do your own query of the Water Quality Assessment information, use one of the following tools:

  1. Use the Simple Query Tool to quickly create a list of waters that are specific to your needs. You can create lists for specific categories, waterbodies, pollutant parameters, and other information, in whatever combination you choose.
  2. Use the interactive mapping tool to see a graphic representation of the Water Quality Assessment.  This is a GIS (Geographic Information System) application developed specifically by Department of Ecology to help you to find waters you are interested in and the associated information for segments of waters.
     
  3. Use the GIS Map Information to view maps of 303(d) listed waters.  To access the map for the 2004 data, after clicking on the link (above) scroll down the "Ecology's Statewide Data Sets table" until you reach "2004 303(d) Candidate List of Impaired and Threatened Water Bodies".
     
  4. Can’t find the WRIA you are looking for?
