Mecklenburg County, NC – During their latest assessment of Lake Wylie conducted on October 21, 2021, Charlotte-Mecklenburg Storm Water Services observed active Blue-Green Algae (cyanobacteria) blooms in Boyd’s and Snug Harbor Coves. A bloom was also observed in a third unnamed cove in the area where the Catawba Yacht Club is located as shown in the attached map. The following safety measures are recommended for these three (3) coves:

  • 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.

All lake users are recommended 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 above.
