The State Water Quality Assessment and Monitoring Project (SWAMP) is a state wide project responsible for collecting, analysing and reporting the ambient water quality condition of rivers in NSW. SWAMP collects water quality data monthly to: assess ambient river water quality in terms of electrical conductivity, temperature, turbidity, total suspended solids, pH, dissolved oxygen, phosphorus and nitrogen at selected sites across NSW provide high quality, long term, statistically robust data to enable condition and trend reporting provide data to enable measures of compliance with state and national guidelines and standards, and provide a framework of river water quality monitoring across NSW upon which other programs can build. Note: If you would like to ask a question, make any suggestions, or tell us how you are using this dataset, please visit the NSW Water Hub which has an online forum you can join.

The Surface Water Science team in DCCEEW employs WaterNSW to monitor water quality at almost 200 sites every month within the major rivers and streams of NSW, through the State Water Quality Assessment and Monitoring Program (SWAMP). This data is used to understand long-term trends in water quality throughout NSW and to develop scores for the water quality index. An annual report is written for every major river and its tributaries within the Murray-Darling Basin as well as the major rivers of the North coast, Hunter and South coast catchments and published in the NSW DCCEEW Water Publications Library. These reports include background information for each catchment including extreme events, catchment use, monthly rainfall, daily flow and dam capacity data. The reports also show the water quality index rating for each site within the catchment as well as water quality data. A new addition has been made to the 2022-2023 reports which includes long-term trends in water quality over the last 10 years.

The Drinking Water Surveillance Program (DWSP) monitors water quality at selected municipal drinking water systems for scientific and research purposes. DWSP is a voluntary partnership that compliments the regulatory monitoring that must be done by the drinking water systems. DWSP monitors for inorganic, organic and radiological parameters. Water quality data are available by individual years.

The Waterbody Inventory/Priority Waterbodies List (WI/PWL) dataset is an inventory of the state's surface water quality. This dataset provides a summary of general water quality conditions, tracks the degree to which a waterbody supports its designated uses, and monitors progress toward the identification and resolution of water quality problems, pollutants, and sources.
