Statewide River Water Quality Assessment (DWER-038)

Statewide River Water Quality Assessment (SRWQA) 2004 & 2008 uses water quality data collected as far back as 1998 to determine the status and trends of nine water quality parameters for all waterways in the state, where consistent data is available.

The project was undertaken by the Water Science Branch of the Department of Water and Environmental Regulation in 1999 and 2004 has now been updated to include water quality information up to the end of 2007. This dataset only shows the classifications and trends from the 2004 and 2008 assessment.

The Assessment focused on colour, dissolved organic carbon, dissolved oxygen, pH, total nitrogen, total phosphorus, total dissolved salts, total suspended solids and turbidity. A total of 255 sites from 23 basins in Western Australia (out of a total of 44) were included in the 2008 update with 126 of these being assessed for the first time in 2008. In 2004 232 sites were assessed. Due to a lack of data numerous sites that were assessed in 2004 are not included in the 2008 update. Many basins had no data, whilst the others lacked recent monitoring data. The status and trend results were compiled into an excel spreadsheet.

Dataset was formally known as Statewide River Water Quality Assessment (DOW-056)
