Authorities continue to monitor blue-green algae in Lake Wylie

Charlotte-Mecklenburg Stormwater Services completed the last assessment of Lake Wylie on Monday, September 20.

MECKLENBURG COUNTY, NC – No active blue-green algae blooms have been reported in two coves of Lake Wylie following a recent assessment by Charlotte-Mecklenburg Storm Water Services.

According to a new statement provided by the ministry, officials conducted the study on Monday, September 20 and found no active blooms at Boyd’s or Snug Harbor Coves.

On September 13, authorities first discovered blooms in both coves, saying this illustrates how quickly the location and extent of an algal bloom can change.

The press release says it is important to look for visual signs that an overgrowth is occurring before entering the water.

Some of the visual signs include bright green, blue, uncovered and / or dirty water.

If you come into contact with water contaminated with blue-green algae, you are advised to use the following safety measures.

  • People and pets do not come into contact with water or algae.
  • Do not handle, cook or eat dead fish that may be present. Avoid fishing in the flowering area.
  • If you come into contact with an algae bloom, wash yourself thoroughly.
  • Use clean water to rinse animals that may have come in contact with an algae bloom.
  • If you or your child seems ill after being in water with an algal bloom, get medical attention 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, see a veterinarian immediately.

Authorities confirm that 15 blue-green algae blooms were reported on Lake Wylie during the months of August and September.

In the press release, officials say: evaluations will continue until no proliferation of active cyanobacteria is observed for two (2) consecutive weeks; therefore, an evaluation will take place during the week of September 27, 2021 and the results will be communicated.

The agency also provided a means of posting bathing advisories related to water quality conditions.
