Click on a dot on the map to find out further information about the site including any warnings that are currently in place.
Each dot on the map represents a monitored site and the colour of the dot represents the daily swimming risk assessment rating.
This current rating is updated twice daily, and takes into account the monitoring results from the previous three years and local weather conditions (recent and forecast rainfall).
Click on the Map legend to find out what daily swimming risk ratings the different coloured dots represent.
You may also see a difference between the latest test result and the daily swimming risk category – this is because the risk category is updated each day, and may be different to the most recent test results because local conditions change quickly. We use the latest test results to help us to cross-check the process for assigning daily swimming risk categories, and help us to improve the way we update information for the public.
Any warnings currently in place at a site are denoted by a red circle and/or a red flag. These relate to the recent site risk assessment which may be due to high bacterial levels, a toxic algae alert and/or a sewage overflow warning.

Water quality in our rivers and at our beaches is generally pretty good over the summer, except in poor weather conditions. Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for at least two days (48hrs) after heavy or prolonged rainfall – even if a site generally has good water quality.
Be clever – don’t swim after wet weather!
