Summer is near, and Austin’s blue-green algae has appeared

Blue-Green Algae

As of May 15, 2023, the City of Austin announced the presence of blue-green algae at every monitoring site on Lady Bird Lake and Lake Austin, except Walsh Boat Landing.

Harmful algae has been recorded on Lady Bird Lake since 2019, which has sickened and killed several dogs. Since then, there has been harmful algae on Lady Bird Lake every year. In addition, they have detected blue-green algae on Lake Austin.

Exposure can happen through ingesting or touching the algae. Because of the history of blue-green algae and its toxicity, people and pets are strongly urged to avoid contact with it.

The City of Austin recommends the following tips when visiting natural bodies of water:

People and Pets

• Do not drink water directly from natural bodies of water.
