Algae Attack
Austin's Lady Bird Lake enters final phase of toxic algae treatment

This algae has kept dogs out of the water and worse for years.
The city of Austin is launching the final phase of a five-year program to fight harmful cyanobacteria, or blue-green algae, in Lady Bird Lake.
On Monday, June 9, crews will begin spraying a special lanthanum-modified clay mixture on the lake.
The lanthanum molecule binds to phosphorus, which serves as a nutrient of the toxic blue-green algae. After it's bound into a mineral, the phosphorus becomes unavailable for the algae to consume, essentially robbing it of one of its primary food sources.
The toxic algae has killed dogs that have gone into the water and become exposed to it.
The applications that will be done on Monday will happen in three places:
- Red Bud Isle
- The boat ramp on the north shore of the lake, west of Interstate 35
- The north shore of the lake between I-35 and the lagoon behind the Festival Beach Boat Ramp
If more time is needed, a contractor will continue the work on Tuesday. A second and third application are planned for July and August, when the chances of algae forming, and the potential to produce toxins, increases because of the hotter temperatures.
The substance will temporarily cloud the water. While the lanthanum-modified clay mixture is safe, recreational boaters are urged to stay away from the barge that will be applying the substance.
How to minimize the risk of exposure
Humans, pets and livestock that interact with harmful algae can become sick, and extreme cases can cause paralysis or death. The LCRA says people who enter the water do so at their own risk, but there are tips to keep pets safe.
