Part of Barwon River still closed due to blue-green algae

February 6, 2020 BY

One of the warning signs now on display next to the Barwon River.

The Barwon River through Geelong remains closed from below Fyans Park to Breakwater Road following an outbreak of blue-green algae.

Results received by the Corangamite Catchment Management Authority yesterday (Wednesday, February 5) indicate blue-green algae levels are dropping.

Another sample has been collected and the Corangamite CMA will make a public announcement as soon as it receives results.

A combination of hot weather, low water flows and high nutrient levels in the Barwon River have contributed to the outbreak.

During algal outbreaks, people and their pets should avoid contact with the water.

Contact with blue-green algae can cause skin rashes, eye and ear infections, vomiting and diarrhoea, mouth ulcers, sore throat and asthma symptoms.

Corangamite CMA’s Barwon through Geelong Co-ordinator Denis Lovric said people should also avoid eating shellfish or fish caught in contaminated water. Anyone experiencing a reaction should seek medical help.

Blue-green algae blooms can be seen with the naked eye across the water surface.

Blue-green algae toxins are colourless and odourless and can remain at dangerous levels in water even after the blooms have disappeared.
