Lord Mayor Michael Harbison confirmed in a statement today that blue green algae levels were above recommended health levels.

“Adelaide’s extended heat wave combined with a lack of rain has created perfect conditions for the development of blue green algae in the River Torrens,” said the Lord Mayor.

“The Adelaide City Council has closed the River because of high levels of blue green algae, as a precautionary measure to ensure public health and safety is maintained.

“We are continuing to monitor, test and tackle the build-up of blue green algae and the River will remain closed until the levels have dropped to within recommended water quality guidelines.”

The Council has continued to run mechanical aerators and fountains in the river, as well as maintaining eight gross pollutant traps. Modified clay treatments are being considered by the Council as a way of preventing the release of nutrients from the river sediment in order to minimise algal growth.

Members of the public are advised not to come into contact with the water, as it could cause skin irritations. Warning signs are being erected today.
