SUSPECTED blue-green algae bloom was detected from water samples at Lake Hamilton on Tuesday by the Southern Grampians Shire Council (SGSC), indicating an unacceptable level of the potentially harmful bacteria.

Blue-green algae may cause skin irritation following contact with the water, as well as eye irritations, nausea, vomiting, muscle weakness or cramps as reported by some people who have swum through or swallowed the algae.

Council activated its ‘Lake Hamilton Management Plan’s Algae Contingency Plan’ which included warning signs to alert users of the closure.

SGSC wellbeing, planning and regulation director, Rory Neeson said that algae at this time of year wasn’t unusual, but it was important to take the alert seriously and avoid contact to reduce the risk of possible health hazards.

“We know that blue-green algae tends to bloom between October and April, but we do see other type of algae bloom at different times as well,” he said.

“Please avoid swimming, sail boarding, water skiing, fishing and any form of direct contact with the water until further advice by Council.

“The picnic areas and playgrounds are safe to use, but please keep pets away from the water if you are visiting the shore.”

Mr Neeson also said that the council are regularly monitoring the water levels to provide the community with updates as soon as possible.

“At this stage, we are unsure how long the restrictions will be in place,” he said.

“Council will continue to monitor the presence of blue-green algae and advise the community when it is safe to enjoy the lake again.

“We thank the community in advance for adhering to this safety alert.”

The SGSC encouraged anyone who wishes to find out more on this matter to access the brochures and information available at the Hamilton Visitor Information Centre.
