Since late January 2021, blue-green algae have spread across Lake Burrinjuck in New South Wales, Australia. On February 10, 2021, the Operational Land Imager (OLI) on Landsat 8 captured imagery of algae blooms in Lake Burrinjuck and the Murrumbidgee River. Blue-green algae blooms can be fatal for pets and can cause stomach problems, rashes, and even vomiting for humans, if ingested. When the algae die, they sink to the bottom of the lake, where they are decomposed by bacteria. As of March 2, it reported lower concentrations of algae but still advised people not to drink untreated lake water and to exercise caution if partaking in water activities.
