Algae alert reduced

AN outbreak of blue-green algae reported in Clarrie Hall Dam in the Tweed catchment has almost dissipated, regional experts monitoring it said.

North Coast Regional Algal Co-ordinating Committee spokesman Brian Dodd said the waters of Clarrie Hall Dam were recording low levels of blue-green algae and the warning had been downgraded to amber level, which is a medium alert.

“The recent conditions in the Tweed catchment have contributed to the reduction of algae numbers in Clarrie Hall Dam and public warnings could now be modified,” Mr Dodd said.

“Monitoring by Tweed Shire Council has shown that concentrations of blue-green algae have declined.”

Users of Clarrie Hall Dam are asked to be vigilant and keep an eye out for a recurrence of blue-green algae as algal blooms can develop within a 24-hour period.

While medium algae levels were still in place, people were advised to not drink untreated water or to boil water.
