Blue-green algae threat eases
WITH the recent rainfall across the coast, the outbreak of blue-green algae reported in the Coldstream River at Tucabia has dissipated.
North Coast Regional Algal Co-ordinating Committee spokesperson, Brian Dodd, said recent sampling results indicated that levels of blue-green algae in the Coldstream River had dropped and the algal alert warning could be lifted.
"Although the blue-green algae is not a threat at present, users of Coldstream River are asked to be vigilant and keep an eye out for a recurrence of blue-green algae as blooms can develop in a 24 hour period," he said.
Blue-green algae can appear as green paint-like scums on the water and foreshore edges or clumps throughout the water.
"Blue-green algae makes the water appear dirty, green or discoloured and are generally associated with a strong musty or earthy odour," Mr Dodd said.
Blue-green algae can reappear at any time so water users should check to see if the warning signs are present and see if there are any visible signs of algae in the water before entering waterways.
Mr Dodd added Clarence Valley Council was monitoring the Coldstream River and had advised the public of the need to heed the many warning signs put up by Council when blue-green algae is present.
The North Coast Regional Algal Co-ordinating Committee will further advise the public if the situation changes.
