Water quality assessment

The Statewide River Water Quality Assessment 2004 uses recent water quality information to determine the status and trends of nine key water quality parameters for all waterways in the state, where consistent data is available. The project was initially undertaken in 2000 and was subsequently updated to include water quality information up to the end of 2003.

A total of 231 waterways were included in the Assessment. The data is a snapshot of the most recent three-year period for status, and five-year period for trend calculations collected for each site. This website will be updated with the latest water quality classifications and trends every five years.

Community members and regional bodies are encouraged to access this site to learn about the quality of the water in their area. The website is intended to provide an indication of the quality of the water in a stream or river, for those who do not require the actual dataset.

If data is required, please contact waterinfo@water.wa.gov.au.
