AUSTIN, Texas – The City of Austin is warning residents against letting pets swim in bodies of water across the city as harmful blue-green algae is once again being detected.

The two main bodies of water in question are Lady Bird Lake and Lake Austin. City officials say both lakes are currently considered an “increased risk” for the harmful algae.

Water samples taken from Lake Austin are currently being tested and the city says algae blooms have been spotted on Lady Bird Lake. Water samples will soon be taken and tested from that lake as well.

The toxic blue-green algae can quickly kill animals that come into contact with it, including pets like dogs.

In 2019, several Austin-area dogs died after owners took them to swim in natural bodies of water and the pets came into contact with the algae.

Scientists warned at the time that the algae blooms could come back year after year as our climate continues to warm and there is less rainfall in the region.

If you’re planning taking your pet to Lady Bird Lake, Lake Austin, or any other body of water that isn’t actively flowing like stock ponds, the city recommends you take these precautions:

  • Avoid stagnant areas or areas with algae.
  • Do not allow dogs to touch or ingest algae.
  • Rinse your dog after contact with the water.
  • If your dog becomes sick after swimming, take your dog to a veterinarian immediately.
