The Kansas Department of Health and Environment and the KDWP have issued several public health advisories for Kansas lakes due to blue-green algae

Marion County, KANSAS – According to the statement, a harmful algal bloom may look like foam, scum or paint floating on the water and be colored blue, bright green, brown or red.

Unfortunately, blooms can develop rapidly.

So, ladies and gentlemen, if the water appears suspicious or there is decaying algae on the shore, avoid contact and keep dogs away.

 These toxins can be absorbed by ingestion, inhalation of aerosols and even skin contact.
