Algae Bloom

Low levels of toxic blue-green algae are still present in Lady Bird Lake. According to the Watershed Protection Department, which takes samples from the lake biweekly, there needs to be consistently cool temperatures and increased water flow before any major changes happen.

Blooms of blue-green algae on Lady Bird Lake persist, city officials said Wednesday.

After a brief decline in the neurotoxin-laden algae at Red Bud Isle, the Austin Watershed Department says, another swath of algae is covering as much as a quarter of the surface.

The City of Austin says toxic blue-green algae will likely stay in Lady Bird Lake until the weather cools off this fall. So far, it’s been blamed for the deaths of at least five dogs that swam in the lake, and Austin is not the only place dealing with the dangerous bacteria this summer.

Toxic bacteria continue to pose a threat in Lady Bird Lake, according to recent city water testing. Austin's Watershed Protection Department says it's still finding toxic blooms of algae at Red Bud Isle, Barton Creek and downstream from Barton Springs Pool – and that it likely won't go away until mid-October.

A toxic algae bloom at Lady Bird Lake is believed to be responsible for the deaths of a handful of dogs in the last three weeks. The algae, at least initially, cropped up around Red Bud Isle, but it has since spread to other parts of the lake. 

What is it and where did it come from?

The City of Austin says it has found potentially dangerous blue-green algae blooms at Auditorium Shores and Barton Creek downstream from Barton Springs Pool. The algae samples contain neurotoxins that are similar to those found earlier this month at Red Bud Isle, but the city says the concentration of neurotoxins is higher.
