Recent tests have confirmed bacteria levels in the Moore River have returned to the acceptable range, as is usual for this time of year, according to the Shire of Gingin.

But shire staff are continuing to monitor the levels in consultation with the Department of Health.

In a post on Friday, February 17 the shire said it still advised that due to potential amoeba risks, people should not let river water enter the nasal passage at high pressure through activities such as diving or bombing off the pontoon or boats, or water slides off the dunes and they should hold their noses on entry into the water.

“Also, if you have small children playing in the shallower waters, take care that any high-pressure water toys are not aimed at their faces eg, water pistols,’’ the advice said.

In January the Shire of Gingin and the Department of Health warned people to avoid swimming and other full-body water immersion activities in Moore River at Guilderton after testing detected amoeba and high bacteria levels at several sampling locations.

Amoeba can be found in warm fresh water such as lakes and rivers.
