No toxins found in Bull Creek

Monday, August 16, 2021 by Elizabeth Pagano

Water samples taken from Bull Creek on Aug. 6 have tested negative for cyanobacteria, or blue-green algae, but city officials are testing again, given the fluctuations in the flow of water since a possible exposure on Aug. 1. A press release from the city explains that those samples, which were taken out of “an abundance of caution,” should have results available by the end of this week. Although cyanobacteria was first detected in Lady Bird Lake in 2019, the danger is not as great in creeks that are flowing and have cooler water temperatures. The city continues to monitor Lady Bird Lake and Lake Austin, and reports decreasing levels of toxins at Red Bud Isle since June. Find more information about the testing and algae on the city’s website.
