OVERLAND PARK, Kan. — Officials from the Kansas Department of Health and Environment (KDHE) are warning people to stay out of a Johnson County lake. 

KDHE has issued a health advisory for South Lake in Overland Park due to toxic blue-green algae blooms. The water has been deemed unsafe for humans and animals due to the harmful algae blooms.
