UPDATE 5.30PM: Cassowary Coast residents have been urged to conserve water due to the heavy rainfall from ex-tropical cyclone Imogen creating water supply issues across the region.

A Council spokesman said resident have been requested to keep water usage to a minimum until the weather improves.

“The new Bulgun Reservoir commissioned in late 2020 has already assisted Council in avoiding multiple boiled water events in the Tully supply system, however current high water consumption is placing that at risk,” he said.

“Heavy rainfall has increased the turbidity (“dirtiness”) of the water at our Tully intakes and they have been closed. The intakes for Cardwell and Nyleta are also closed. Council is now relying on water storages in our reservoirs to supply clean water.

“If the creek systems run dirty for an extended period there is a risk that our storages will be depleted before our intake creeks run clean again. This would force the implementation of widespread boil water alerts.

“The Innisfail water treatment plant is also being challenged by this weather event and our request to conserve water applies to all properties within the region.”

Residents can reduce their water usage by turning off sprinklers that are set on a timer, reduce the length of time spent in the shower, turning off the tap while you brush your teeth or shave, wait until your dishwasher or washing machine is fully loaded before turning it on and choose shorter, economy wash cycles.

The Cassowary Coast has copped some of the highest falls in the region, with 261mm at the Tung Oil station west of Innisfail recording 261mm and Bulan Creek northwest of Tully recording 205mm since 9am today.

UPDATE TUESDAY: Cairns and the Tablelands are no longer included in a severe weather warning for the Far North, but large parts of the region, including the Cassowary Coast and Tablelands, remain on alert.

At 1pm, ex-tropical cyclone Imogen was about 120 kilometres east of Georgetown, and was slow-moving.

A coastal trough extends from ex-Imogen into the Coral Sea, and is triggering widespread rain areas, heavy showers and thunderstorms for the northeast tropics.
