Overview
A Riverwatch water monitoring program will help us measure change over time, protect existing swimming spots, open new swimming sites and understand what makes water quality change over time.

RiverWatch Monitoring Program
RiverWatch™ was established in 2019 by Sydney Water to monitor and report on water quality at new and planned swimming and recreation sites along the Parramatta River.
Before a new site is opened, routine water quality monitoring is undertaken for more than 12 months. Monitoring results are assessed against the National Health and Medical Research Council Guidelines for Managing Risks in Recreational Water and NSW Water Quality Objectives.
Sydney Water also worked with industry partners to develop a chemical assessment program, which evaluates how chemical contaminants impact river sediment and water quality to ensure there are no risks to human health. The framework and assessment process is based on the enHealth guidance – Guidelines for assessing human health risks from environmental hazards.
Daily water quality forecasts for existing swimming and recreation sites are available through Our Living River’s Interactive Map.
RiverWatch is aligned with similar recreational water quality monitoring programs such as NSW Department of Planning and Environment’s Beachwatch monitoring program, which monitors three of the existing swim sites on the Parramatta River: Cabarita Park beach, Chiswick Baths and Dawn Fraser Baths. Water quality at Lake Parramatta is monitored by the City of Parramatta’s comprehensive Water Quality Program.
Status Update
Assessing recreational water quality in the Parramatta River is an important step in delivering the Parramatta River Masterplan. The Riverwatch microbial monitoring program assesses how microbial contaminants impact water quality in the Parramatta River. Along with the Riverwatch chemical assessment program, it helps inform decisions about proposed swimming sites along the river.

|
December 2023 to February 2024
- Bayview Park Baths predictive model – a recent analysis of model predictions against water quality data collected showed that they matched 85% of the time, within the agreed threshold (and aligning with Beachwatch). As more data is collected at the site, the predictive accuracy of the model will continue to improve.
- Putney Park predictive model – completed in the last quarter. Sydney Water is monitoring predictions against real world data collected, prior to making it publicly available when City of Ryde opens their site.
- Bedlam Bay predictive model – still being developed, but on track to be ready before site opening in 2024. Sydney Water is undertaking intensive monitoring including microbial source tracking (using dog and human markers) as well as CCTV of the local network and where required conducting root-cutting and repairs in the sub-catchment.
- Communication strategy for sediment risks at recreational sites in the Parramatta River: PRCG engaged risk and communications specialist ECF to develop a strategy to communicate the risk associated with swimming/contact with areas that have legacy chemical contamination to a broad audience.
- ECF presented on the strategy and collateral to be developed to the Swim Site Activation Technical Working Group in early December.
