    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 long-term grade.

    Water quality test result

    Current Enterococci statusLast sampled 23 Dec 2024

    The weekly sampling result is a snapshot in time, and is a guide to the recent water quality at this site.

    Long-term grade

    Long-term Enterococci grade5 year sampling

    Long-term grade is important to consider. Based on 5 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.

    What do the long-term grade icons mean?

    Excellent – Risk of illness is less than 1% from contact with the water during the summer bathing period.
    95th percentile of Enterococci / 100 mL is 0 - 40.
    Good – Risk of illness is less than 5% from contact with the water during the summer bathing period.
    95th percentile of Enterococci / 100 mL is 41 - 200.
    Fair – Risk of illness is between 5 and 10% from contact with the water during the summer bathing period.
    95th percentile of Enterococci / 100 mL is 201 - 500.
    Poor – Risk of illness is more than 10% from contact with the water during the summer bathing period.
    95th percentile of Enterococci / 100 mL is more than 500.
    Not available – There were not enough data to determine the long-term grade at this site.
