    The science

    Summer 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 result

    The 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 risk

    Overall 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 changed

    There 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.

    Information about toxic algae

    Dog owners

    Keeping your dog safe and healthy this summer

    A trip to a lake is a lot of fun and knowing how to keep your dog safe means you are able to relax and enjoy the adventure even more.  Potentially toxic algae can be harmful to dogs (and us) – this section shows you what to look for.

    What to do

    • The best thing you can do to keep yourself, your kids and your dog safe is to know what potentially toxic algae looks like and avoid it. 

    • If you are not sure, keep your dog on a lead at a lake and don’t let them in or near the water.  Bring water from home for your dog so that they don’t need to drink out of the lake.

    What is potentially toxic algae?

    Potentially toxic algae, known scientifically as cyanobacteria, are naturally occurring in rivers and lakes in New Zealand, including waterways with good water quality.  Most of the year it is present in lakes at low levels that are not much of a danger.  But algae can be a problem during the summer months, when warm temperatures and nutrients in the lake create an environment where it can thrive, forming extensive blooms which can be toxic to humans, dogs, livestock and wildlife. 

    Scientists do not yet understand when and why this algae turns toxic, so to be safe, always treat it as toxic.

    Dogs are particularly susceptible to poisoning from toxic algae as they may drink  lake water or play in the water. 

    What to look for

    Potentially toxic algae grows within the water column in lakes and cause the water to become murky or cloudy. 

    These free floating algae blooms in lakes are generally green in colour and can look like paint, petrol or pea soup. It can also form foam or scum on the water’s surface, especially at the water’s edge.

    Regional Council staff monitor for these mats in lakes where blooms are known to occur.  Blooms can occur very suddenly (within an hour) so please alert your regional or unitary council if you notice a new algal bloom in a lake.

    What if my dog has eaten potentially toxic algae?

    If you suspect that your dog has eaten toxic algae, you should contact your vet as soon as possible.  Signs a dog has been poisoned by toxic algae include lethargy, muscle tremors, fast breathing, twitching, paralysis and convulsions.
