Map Information:

In accordance with Section 303(d) of the federal Clean Water Act, every two years each state must identify its polluted water bodies and submit this list to EPA. Our maps show where in Washington State these estuaries, lakes, and streams are located.

Digital 303(d) GIS data is available for download on this website at:  GIS Data page

For more information on the 303(d) program, check out Ecology's Water Quality website and/or contacts webpage.

NOTE:  Ecology also has an interactive web application to view 303(d) listed water bodies in your web browser (Internet Explorer only).
