The state Department of Health has issued a brown water advisory for Maui from Waiehu Beach Park to Paukukalo and from Kealia Pond to Kalama Park due to heavy rains and flooding.

The public is advised to stay out of flood waters and storm water runoff due to possible overflowing cesspools, sewer manholes, pesticides, animal fecal matter, dead animals, chemicals, flood debris, Leptospirosis and other water-borne diseases. If coastal waters are turbid and brown, stay out.

On Kauai, officials poted warning signs at Kikiaola Small Boat Harbor after the Kikiaola irrigation ditch was opened this morning, allowing storm water mixed with treated wastewater to flow into the harbor.

The ditch was opened to prevent flooding from occurring in the Waimea area.

Officials estimate that up to 2.25 million gallons of treated wastewater had been stored in the irrigation ditch.
