‘Potentially harmful’ algae blooms found in metro Atlanta lake

FAYETTE COUNTY, Ga. — Peachtree City officials issued a warning about a “potentially harmful” algae blooms found in one of its lakes.

After blooms were detected, testing confirmed that it was two types of algae, anabaena and microcystis, found in Lake Peachtree near the lagoon off Battery Way.

The city says the algae blooms are likely from the warm temperatures and lower rainfall. The city advises that all people and pets should avoid “all contact” with the water. City workers have posted signs in hopes people take the warnings seriously.

Channel 2′s Tyishsa Fernandes was at Lake Peachtree Friday, where it’s unclear how long it will be before the lake reopens.

That’s left a lot of neighborhood kids really disappointed.

The water looks normal from a distance, but the algae in the water can cause some health concerns including diarrhea and vomiting as well as dizziness, tingling fingers and toes and numb lips.

Bill Hare said his niece and nephew were in the lake this week, but they won’t be back in until city leaders say it’s safe.

“They’ve been swimming in it (before) and they haven’t had any issues,” Hare said.

Officials said that as the days get shorter and cooler, the algae will die off.

Lake Peachtree spans 240 acres in Peachtree City and is one of three lakes in the city. Lake Kedron and Lake McIntosh have not been impacted.

Anabaena and microcystis are types of cyanobacteria, or what is more commonly known as blue-green algae. Unlike other forms of algae, these types can produce toxins.

Symptoms of anatoxin poisoning include numb lips, tingling fingers and toes, and dizziness. Symptoms of microcystin poisoning include abdominal pain, diarrhea, and vomiting.

City officials said that if elevated levels are ingested, it could cause serious neurological and liver damage.
