Algae warning for dam visitors

A RED alert for blue-green algae has been issued for Clarrie Hall Dam.

The North Coast regional algal coordinating committee spokesman Brian Dodd said people should avoid all contact with the dam water.

“Residents and visitors should avoid all contact with the algal bloom in Clarrie Hall Dam and ensure animals such as dogs are kept away from the bloom as well,” Mr Dodd said.

If contact is made with the skin, blue-green algae can cause skin rashes, asthma and eye and ear irritations.

Animals are likely to become extremely sick if they drink blue-green algae water, and in rare cases animals have died from ingestion, the committee cautioned.

Mr Dodd said there would be no impact on drinking water for residents who are connected to the town water supply.

Warning signs will remain in place around Clarrie Hall Dam until the bloom ends.

“Tweed Shire Council will continue monitoring this blue-green algal bloom and the community will be advised when conditions change,” Mr Dodd said.

The council’s water manager Anthony Burnham said good flows in the Tweed River ensured it had not been affected between the Doon Doon Creek junction, through Uki to the Bray Park Weir.
