Public review of the latest updated Water Quality Assessment and 303(d) List for Washington State

The Washington State Department of Ecology is conducting a public review of the latest updated Water Quality Assessment and 303(d) List for Washington State, focusing on fresh water data. The draft Assessment results are available for a 60-day public review and comment period from March 17, 2015 – May 15, 2015.

This Assessment updates fresh water listings based on data collected as of the end of December 2010. New with this Assessment, we are updating how we map polluted rivers, lakes, and streams. We are moving from a land-based system using the Public Lands Survey of a Township/Range/Section to a water-based “National Hydrography Dataset” (NHD) system. The mapping change helps us be consistent with other agencies and states, and is strongly recommended by the Environmental Protection Agency (EPA).

This Assessment fulfills Washington State’s obligations to submit an “Integrated Report” to EPA to meet requirements under the federal Clean Water Act, sections 303(d) and 305(b). The Integrated Report: 1) identifies polluted waters (also known as the 303(d) List), and 2) reports on the status of water quality statewide where data is available (called the 305(b) Report).

Information on the updated Water Quality Assessment, including access and instructions on using the Search and Map tools as well as other related information, can be found on Ecology’s website at:
