Webster State Park in Rooks County announced Wednesday afternoon the lake's beach is closed due to a high county of blue-green algae, which can be dangerous to people and animals.
The rest of the lake is under a watch, meaning boaters should use caution. Additional testing is expected.
In case of harmful algae contact, doctors or veterinarians should be contacted for symptoms including nausea/vomiting, diarrhea, rash, irritated eyes, seizures, breathing problems or other unexplained illness.
Possible algae bloom illness should also be reported to KDHE at (877) 427-7317.
