Officials are responding to a blue-green algae bloom at Lake Allatoona near Red Top Mountain Park Marina after the bloom was identified on May 7.
Authorities are discouraging people from swimming in the affected area because this type of algae can produce toxins that may be harmful to humans and animals.
The Cobb County-Marietta Water Authority said it continues analyzing water samples to identify and remove harmful contaminants and said the drinking water remains safe.
