Red alert on blue green algae for Clarrie Hall Dam
HIGH levels of blue green algae have been detected in the Tweed catchment of Clarrie Hall Dam.
A red alert has been initiated by the North Coast Regional Algal Coordinating Committee.
Committee chair David Basso said people should avoid all contact with the water.
"The Northern Coast Regional Algal Co-ordinating Committee, in conjunction with Tweed Shire Council, advise all people who use Clarrie Hall Dam for recreation and farming purposes to be award of the situation," Mr Basso said.
He said there was no impact on the drinking water supplied to residents who are connected to town water.
"Routine sampling by the Tweed Shire Council has detected high levels of blue green algae in the dam and accordingly, wishes to advise landholders in the Doon Doon Creek catchment area to avoid contact with the affected water," Mr Basso said.
Warning signs have been positioned around Clarrie Hall Dam and will remain in place until the bloom subsides.
"The residents and visitors should avoid all contact with the algal boom in Clarrie Hall Dam and ensure animals such as dogs are kept away from the bloom as well."
Livestock owners are reminded to continue to check stock water supplies for signs of blue green algae and to remove stock from foreshores where surface scum is visible or where blue-green algae are suspected.
Blue green algae are known to cause skin rashes, asthma and eye and ear irritations if contacted and diarrhoea and other health problems if ingested.
Animals can become very sick as a result of drinking water affected by blue-green algae and there have been cases of animal deaths.
Avoid eating mussels or crayfish from the red alert warning areas.
Mr Basso said any fin fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of before consumption.
"Tweed Shire Council will continue monitoring this blue-green algal bloom and the community will be advised when conditions change," Mr Basso said.
