Tweed Shire Council is having a run of bad blue-green algae luck – after announcing yesterday that there was an amber alert for the Tweed River at Uki and Bray Park Weir, and last week’s amber alert for Clarrie Hall Dam, Council has today issued a red alert for blue-green algae at Clarrie Hall Dam following its latest water test results. A red alert means the water should be treated as toxic to both humans and animals and should not be consumed without being treated. It is also potentially unsafe to come into contact with the water. Council’s Manager Water and Wastewater Operations Brie Jowett said the blue-green algal bloom at the dam is increasing rapidly.
