Mecklenburg County, NC – During their latest assessment of Lake Wylie conducted on September 20, 2021, Charlotte-Mecklenburg Storm Water Services did not observe any active Blue-Green Algae (cyanobacteria) blooms in Boyd’s or Snug Harbor Coves. On September 13, 2021, assessments revealed active blooms in both coves, which illustrates how quickly the location and extent of an algal bloom can change. Therefore, it is important to look for 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 measures below.
- 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 bloom area.
- 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 attached map illustrates the areas where active cyanobacteria blooms have been observed by Charlotte-Mecklenburg Storm Water Services since assessments began in Lake Wylie in August 2021. Assessments will continue until no active cyanobacteria blooms are observed for two (2) consecutive weeks; therefore, an assessment will occur during the week of September 27, 2021 and results will be reported.
