AUSTIN, Texas — City officials are urging residents to use caution around local lakes and creeks after blue-green algae, which can be toxic, was seen in Austin waterways.
Austin Watershed Protection staff have identified algae mats in lakes and creeks this winter. The mats often appear as dark blobs floating on the surface and may be mixed with other types of algae. Officials said conditions are expected to become more favorable for algae growth as spring approaches.

Residents and pet owners are advised to assess conditions before entering the water. People should look for algae along the shoreline and avoid water that appears stagnant, warm or murky. Officials said people should not enter the water if they see scum, surface film or visible algae, or if there has been rainfall within the past three days, as those conditions can indicate poor water quality.
Swimmers are advised not to drink water from natural bodies of water and to avoid contact with algae. People and pets should rinse off thoroughly after being in the water, and dogs should not be allowed to lick their fur before being rinsed.
Anyone experiencing sudden or unexplained illness after swimming should contact a medical provider or veterinarian. Suspected algae-related illnesses can be reported through the city’s online reporting form.
