The City of Austin issued a warning for people and animals to avoid swimming at the iconic Sculpture Falls swimming hole on the Barton Creek greenbelt. As far as we know, this has never happened before. The City detected a toxic compound produced by cyanobacteria. The toxin was found in the water column, not within large algae mats, so that it is more directly harmful to people and animals swimming in the water. Read the City’s press statement here. SOS is committed to finding and stopping the cause of this pollution as soon as possible.
