Dangerous blue-green algae warning for Lake Tuggeranong | Canberra weather

news, latest news,

An “extreme blue-green algae alert” has been issued for Lake Tuggeranong. This is the latest outbreak despite millions of dollars spent to prevent such incidents which now occur every year. The ACT government warns that touching objects “carries an increased risk to health.” Symptoms of exposure may be skin irritation, flu-like symptoms and “gastrointestinal illness”. Pet owners are cautioned that pets can die if they come in contact with it. The government has closed the lake to recreation that involves contact with water, recreation such as swimming, diving, water skiing or windsurfing. Other hobbies that don’t need such close contact – such as rowing, fishing, boating, and canoeing – are still permitted. But health officials warn people should avoid these “secondary contact” recreations unless they know what to do if they have algae on their skin. They should also be able to shower quickly after coming into contact with the algae. Health officials are particularly concerned about “seaweed scum.” “People should avoid contact with algae scum. Any clothing that has been in water should be washed to remove blue-green algae residue. »Organizers of events on or near the water should ensure that participants are aware of the risks and what to do if they come in contact with algae. Animals should also be kept away from water. “Pet owners should not allow their pets to swim or drink water because blue-green algae can make pets very sick or even cause death,” a statement said.

Water users should look for algae warning signs that indicate the current alert level for algae. Warning signs are located in public access areas. GP. “The algae was so thick on Lake Burley Griffin in the past that it can be seen from space. The European Space Agency’s Copernicus Sentinel-2 satellite picked up masses of blue-green substance while ‘it was passing over south-eastern Australia. The algae in abundance is usually caused in the summer when temperatures rise. Calm waters, such as Lake Tuggeranong and Lake Burley Griffin, are ideal conditions as the light from the sun acts chemically on organisms in hot water., rain, regular or high flows provide ideal conditions for the growth of algae, “according to the ACT government.” Thermal stratification (when lake water forms layers) means that the cooler lower layer omes anoxic (oxygen-free), causing the release of nutrients from the sediments that feed the algae. ”Our reporters work hard to provide local and up-to-date news to the community.
