TOPEKA (KSNT) – Kansas wildlife and health officials are warning people to be on the lookout for a harmful algae in the state’s lakes and waterways this year.
The Kansas Department of Health and Environment (KDHE) and the Kansas Department of Wildlife and Parks (KDWP) are issuing a joint warning on harmful algal blooms (HAB) and blue-green algae. Both departments say the start of HAB season has arrived for the Sunflower State.
This follows the water recreation season in Kansas which officially starts on April 1 and runs to Oct. 31. Kansans are warned to stay vigilant for HABs and blue-green algae while on or near the water this year. Lakes and reservoirs in Kansas regularly become afflicted with this algae every year.
Lakes can be classified at different levels in Kansas for the presence of blue-green algae: watch, warning and hazard. The KDHE recommends different precautions to those who might come into contact with lakes afflicted by the algae:
Watch
Signage should be posted at all public access locations.
Water may be unsafe for humans/animals.
Avoid areas of algae accumulation and do not let people/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 clean water and eat fillet portions only.
Warning
Signage should be posted at all public access locations.
Inhalation of spray or aerosols may be harmful.
Lake water is not safe to drink for pets or livestock.
Lake water, regardless of blue-green algae status, should never be consumed by humans.
Water contact should be avoided.
Fish may be eaten if they are rinsed with clean water and only the fillet portion is consumed, while all other parts are discarded.
Do not allow pets to eat dried algae.
If lake water contacts skin, wash with clean water as soon as possible.
Avoid areas of visible algae accumulation.
Hazard
Signage should be posted at all public access locations.
It is recommended that either a portion of the lake or the entire lake or zone be closed to the public.
In some cases, the adjacent land should be closed as well. Actual setback distances will be determined on a site-specific basis, if necessary.
When partial closures (i.e., beach or cove) are issued, the remaining lake or zone area will carry a warning status.
Jill Bronaugh with the KDHE says toxins emitted by a HAB can cause rashes, vomiting, diarrhea, fever, sore throat and a headache. Blue-green algae may appear like paint or scum on the surface of the water, according to the KDHE.
If you or a pet comes into contact with the algae, rinse the impacted area clean with fresh water. If you come into contact with a HAB, reach out to the KDHE by filing a report online here.
