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 formerly known as Statewide River Water Quality Assessment (DOW-056) {"type": "Polygon", "coordinates": [[[113.76912987500009, -35.029695887999935], [129.09238211600007, -35.029695887999935], [129.09238211600007, -15.196260523999968], [113.76912987500009, -15.196260523999968], [113.76912987500009, -35.029695887999935]]]} 113.76912987500009 129.09238211600007 -35.029695887999935 -15.196260523999968 Rivers Surface water monitoring Water Quality Water Surface Statewide River Water Quality Assessment (2004 & 2008) documentDigital Metadata Statement: Department of Water and Environmental Regulation (DWER) TXT Geopackage documentDigital This resource provides the latest snapshot of the dataset as a GeoPackage.

WFS allows a user to download and spatially analyse the features within a datset. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as QGIS and ArcGIS. WFS ArcGIS Server Map Service documentDigital An ArcGIS Server Map Service offers access to a geographic dataset - such as a map or imagery - by providing a set of tiled images for use in web-based maps. Depending on the capabilities enabled, this web service may also allow a client to dynamically draw, search, and query its features. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as ArcGIS and QGIS. API ArcGIS Server Map Service Web Mapping Service documentDigital Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the internet that are generated by a map server using data from a GIS database. WMS allows a user to spatially visualise the dataset, and query individual features, but does not allow downloading the raw data.
