The scienceSummer season monitoring
LAWA shows the best available water quality information to help you decide where to swim. For many sites there are two types of information available, the weekly sampling result and the overall bacterial risk.
Weekly sampling result
Weekly E. coli resultThe weekly sampling result is a snapshot in time and is a guide to the recent water quality at this site.
Overall bacterial risk
Overall E. coli riskOverall bacterial risk is important to consider. Based on 3 years of data it is a guide to the general water quality at this site.
Reminder
Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for 2 – 3 days after heavy or prolonged rain – even at sites that generally have good water quality. Check that the water is clean and clear before taking a dip.
Conditions may have changedThere has been significant rain since this site was last sampled. This may have affected the water quality at this site.
Potentially toxic algae can rapidly bloom to harmful levels, and not all freshwater sites are monitored for toxic algae. Play it safe, if you can see toxic algal blooms in rivers or lakes, avoid contact or choose another site to swim.
What do the icons mean?
Suitable for swimming – These sites are generally suitable for swimming.Caution advised – Usually suitable for swimming but younger children and older people may be at increased risk at times. If potentially toxic algal blooms are present, avoid contact.Unsuitable for swimming – These sites may be a health risk and are not considered suitable for swimming most of the time.No data – There are no recent results available, or there are not enough data points to calculate an overall bacterial risk result.Summer season monitoring history

Our lakes, rivers, and beaches are great natural playgrounds but they can be unpredictable. Be aware of other potential risks such as rips, strong currents, sudden drop offs, or underwater objects before jumping in. LAWA recommends that you avoid swimming for 2 - 3 days after heavy rainfall and follow the advice of any warning signs in place.
