Updated: 05/08/2023. A Brown Water Advisory has been issued at Waimea Bay on O‘ahu. Nearby stream flow has resulted in runoff and debris entering into coastal waters. The public is advised to stay out of runoff waters due to possible overflowing cesspools, sewer, manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and associated flood debris. Not all coastal areas may be impacted by runoff, however, if the water is brown stay out. Continue to practice good personal hygiene and follow-up with your primary care physician if you have any health concerns.
