Mecklenburg County, NC – During their latest assessment of Boyd’s Cove on Lake Wylie conducted on August 30, 2021, Charlotte-Mecklenburg Storm Water Services observed active Blue-Green Algae (cyanobacteria) blooms in four (4) smaller cove numbers 2, 4, 6, and 7 within Boyd’s Cove on Lake Wylie as shown in the attached map. Assessments for cyanobacteria blooms in Boyd’s Cove have been ongoing since blooms were first observed on August 6, 2021. Staff will continue to monitor conditions until it is confirmed that active blooms are no longer observed. A summary of the findings from these assessments is provided in the attachment. Although algae are commonly observed in lakes and ponds, cyanobacteria are a type of algae that is less commonly observed and is of particular concern because it has the ability to produce toxins that may be harmful to humans and pets. The Mecklenburg County Health Department recommends the following for the four (4) small coves where active blooms were observed:
- People and pets do not contact the water or algae.
- Do not handle cook or eat dead fish that may be present. Avoid fishing in the area of the bloom.
- If you come into contact with an algal bloom, wash thoroughly.
- Use clean water to rinse off pets that may have come into contact with an algal bloom.
- If you or your child appears ill after being in waters containing an algal bloom, seek medical care immediately. Symptoms include loss of appetite, vomiting, diarrhea, cough, difficulty breathing, sore throat, itchy skin or rash.
- If your pet appears to stumble, stagger or collapse after being in a pond, lake or river, seek veterinary care immediately.
The location and extent of an algal bloom can change quickly so for all areas outside these four (4) small coves, please look for the visual signs that a bloom is occurring prior to contact with the water. Visual signs of a bloom may include bright green, blue, discolored, and/or scummy water. If visual signs are observed, follow the safety recommendations above.
