Water at recreation areas including Black Diamond, Minninup Pool, Stockton Lake and Lake Kepwari is tested regularly for the presence of harmful organisms.
Microbiological testing is seasonal and only carried out from Nov-May each year as this is the time of year where the water temperature is higher and therefore represents a higher level of risk to the general public. Even when test results show no harmful organisms present, the Shire of Collie does not recommend putting your head under water, as the hotter months and increased water temperatures does produce a higher risk.
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.
