Blue-Green Algae Bloom Prompts Public Health Advisory
At Centralia City Lake, Nemaha, County, KS.

The Kansas Department of Health and Environment (KDHE) is advising the public to avoid contact with water in the Centralia City Lake, which is located two miles southwest of Centralia, in Nemaha County, KS.

KDHE has confirmed there is a toxic blue-green algae bloom in the lake, prompting a public safety advisory.  Concentrations of these algae exceed the recommended level of 100,000 cells/ml by the World Health Organization for recreational water use. 

Blue-green algae are found in most surface waters and in heavy concentrations form an algae bloom.    Blue-green algae blooms often resemble green paint floating on the water; in fact blooms are often mistaken as paint spills. When blue-green algae die they can produce an unpleasant smell.  These blooms can cause a number of concerns including production of toxins in the water affecting people, pets and potentially fish and shellfish.

Algae blooms often result when nutrients present in the water (nitrogen and phosphorus), temperature and other environmental conditions stimulate algae growth. The blooms result from long-term build up of nutrients in the water body. Concentrations of blue-green algae in water vary on a daily or even hourly basis due to prevailing winds and currents. In time, algae blooms will naturally die off. 

KDHE recommends the following precautions be taken at Centralia City Lake:

Exposure to toxins from the algae can cause illness and is dependent on the route of the exposure.  Contact with the water, such as wading or swimming, can cause a skin rash, as well as eye, ear and throat irritation.  Ingestion or inhaling aerosols (such as from jet-skiing or boating) of contaminated water can cause diarrhea, vomiting, abdominal cramps, fever, fatigue and flu-like symptoms.  If you develop similar symptoms after contact with the reservoir water, seek medical care from your healthcare provider. 

Animals, especially dogs, can also become ill. Ingestion of the water by pets or cleaning of their coats after contact with water are two common routes of exposure for animals.  If your pet becomes ill soon after contact with the water, contact your veterinarian right away.

KDHE will continue to monitor the situation and rescind the advisory as soon as conditions warrant.

KDHE can be contacted during normal business hours, Monday through Friday, at 785-296-5500, if anyone has additional questions or concerns.
