Some species of algae can produce toxins that cause severe illness in people and animals.
CHARLOTTE, N.C. — Harmful algae blooms have been found in lower Lake Norman, Charlotte-Mecklenburg Storm Water Services announced on Wednesday.Â
The blooms were found by staff members who were investigating reports of possible green algae near the shoreline. Most of the blooms are safe, but some species of algae can produce toxins that are harmful to humans and animals, officials said. Kids and pets are more vulnerable to exposure.
The discovery comes a few months after treatment started for blue-green algae at the lake. It’s been a problem for about two years. In February, several agencies provided $60,000 in funding for the treatment plan. Officials said at least 10 acres of Lake Norman would require treatment once a month for about six months. The same type of algae found in Lake Norman was also discovered in Lake Gaston.Â
“We’re kind of tackling the problem really early in the infestation stages,” Jessica Baumann with NC State Extension said. “I’m excited to see how quickly [Lake] Norman responds, and if we can get these 10 acres under control and in two years instead of four years. ”
Storm Water Services says it’s impossible to tell if an algae bloom is harmful just by looking at it, so they’re discouraging people from swimming, boating, kayaking or fishing near possible algae blooms. People should also avoid drinking the water or using the water for washing or watering plants.Â
If a person or their pet comes into contact with discolored or scummy water, they should immediately wash thoroughly and seek medical or veterinarian care if showing any symptoms of illness.Â
Storm Water Services says its crews will continue to survey the area until the blooms are no longer present. Anyone who sees a bloom is asked to report it immediately by calling 704-663-1699. In South Carolina, residents can report algae blooms at 803-898-8374.Â
