Water at recreation areas including Black Diamond, Minninup Pool and Stockton Lake is tested regularly for the presence of harmful organisms.
Microbiological testing is seasonal and only carried out from Nov-May each year as is the time of year where the water temperature is higher and therefore represents a higher level of risk to the general public.
Testing is also carried out at Lake Kepwari, which is not yet open to the public.
Amoebic meningitis is a rare but fatal infection caused by the Naegleria fowleri amoeba which lives in fresh water and damp soil. When water containing active amoebae enters the nose, the amoebae travel to the brain causing inflammation and destruction of brain tissue.
