Between September 2022 and February 2024, DCCEEW undertook water quality monitoring surveys across the North Coast, Mid Coast and Hawkesbury-Nepean regions to better understand the physicochemical and biological condition of waterways in response to flood impacts. Approximately 11, 000 samples were collected routinely and in response to significant wet weather events and flooding, while Telemetered monitoring stations provided real-time data across six waterways to better understand fine-scale changes in water quality.

The dashboard data collates multiple water quality parameters from thousands of samples collected through manual field sampling and in real-time via telemetered water quality loggers (2 land-based sites and 6 smart buoys). 8 loggers were installed through the east coast project to measure real-time data every 15 minutes across six waterways. The dashboard also includes real-time data from an additional 10 loggers located across NSW that contribute water quality data to other monitoring programs.

Click the 'Real-time data' tab on the left menu in the dashboard to find out where the loggers are located and access the real-time data. Scroll through the North Coast, Mid Coast and Hawkesbury-Nepean tabs on the left menu to view the data from monthly water quality samples collected since the 2022 flood events.
