TOPEKA, Kan. — The Kansas Department of Health and Environment, in conjunction with the Kansas Department of Wildlife, Parks and Tourism, has issued public health advisories or watches for lakes in the area because of blue-green algae.

Marion County Lake was lifted from being under a warning on Oct. 17. There is still a watch for Lake Afton in Sedgwick County.

A watch means that blue-green algae has been detected and a harmful algal bloom is present or likely to develop. People are encouraged to avoid areas of algae accumulation and keep pets and livestock away from the water.

During the watch status, KDHE recommends the following precautions be taken:

Water may be unsafe for humans and animals, so avoid areas of algae accumulation and do not let people or pets eat dried algae or drink contaminated water.

Swimming, wading, skiing, and jet skiing are discouraged near visible blooms. Boating and fishing are safe. However, inhalation of the spray may affect some individuals. Avoid direct contact with water and wash with clean water after any contact.

Clean fish well with potable water and eat fillet portion only.

The Kansas Department of Health and Environment takes samples of publicly-accessible bodies of water for blue-green algae when the agency receives reports of potential algal blooms in Kansas lakes. Based on sampling results, KDHE reports on potentially harmful conditions.

Kansans should be aware that blooms are unpredictable. They can develop rapidly and may float around the lake, requiring visitors to exercise their best judgment. If there is scum, a paint-like surface or the water is bright green, avoid contact and keep pets away. These are indications that a harmful bloom may be present. Pet owners should be aware that animals that swim in or drink water affected by a harmful algal bloom or eat dried algae along the shore may become seriously ill or die.
