The Hawaii Department of Health is advising the public stay out of the waters in Kaohaoha Gulch and the coastal waters fronting the gulch in Ookala.

Officials say, water within Kaohaoha Gulch was contaminated with animal waste due to an overflowing retention pond at the dairy facility caused by heavy rainfall.

Signs have been posted.

The DOH says, heavy rain has also resulted in stormwater runoff entering into coastal waters.
