Toxin levels decline but blue-green algae still present in Highland Lakes

“We are pleased to see the level of toxicity is continuing to decline, but even a small amount of this toxin can be dangerous if ingested,” John Hofmann, LCRA executive vice president for water said in the release.

Despite the drop in toxins, Hofmann said people should avoid contact with algae in the Highland Lakes and should keep their pets from playing in and ingesting the material.

Symptoms of exposure in dogs can appear within minutes of exposure and can include drooling, vomiting and difficulty breathing, according to LCRA.

Animals are more susceptible to illness as they are more likely to ingest and play in shallow water. Still, people can experience eye and skin irritation as a result of blue-green algae, and more severe reactions can occur if large amounts of untreated lake water are ingested.

Under federal guidelines, water utility operators are responsible for the testing and removal of harmful algal toxins from drinking water supply. LCRA has not reported a threat to the public water supply.
