UPDATE: M'boro flood peak now expected late on Monday

UPDATE: Floodwaters are expected to peak at 13m in Tiaro in the next few hours meaning Maryborough may not see the full extent of the rising Mary River until late on Monday or early on Tuesday.

The Local Disaster Management Group and the Bureau of Meteorology are monitoring flood gauges at Tinana Creek, Miva and Owanyilla.

Fraser Coast Mayor Gerard O'Connell said the waters were slowly making their way down the river.

"The flood heights are just creeping," he said.

"That's a bit of an unusual situation."

Cr O'Connell predicts the flood height will peak at 5.5m.

"If it's 5.5m there'll be splash up on the Lamington Bridge," he said.

Mary River on Monday morning: The Mary River is flowing swiftly past Queens Park on Monday morning as it builds towards a peak expected in Maryborough late on Monday night or early on Tuesday morning.

 

EARLIER UPDATE: The Mary River flood is progressing slowly with the waterway not expected to peak in Maryborough until late on Monday afternoon.

Fraser Coast Disaster Planning co-ordinator Mal Churchill said minor flood levels, between 5m and 8m, were still expected and they were waiting for more definitive advice from the Bureau of Meteorology.

"BoM won't give us the information until certain other areas along the river have peaked," he said.

"This one seems to be progressing fairly slowly."

Mayor Gerard O'Connell said he didn't anticipate the Maryborough Hervey Bay Rd would be affected but Granville State School would be closed on Monday.

He said he was most concerned about people in rural areas of the upper catchment between Maryborough and Gympie and people would need to keep monitoring the water levels.

Cr O'Connell said businesses in low-lying areas were prepared and workers from fire, police and ambulance services were ready to be stationed in Granville.

"We watch, we wait," he said.

EARLIER: The Lamington Bridge has been closed and Granville residents are preparing for potential isolation as floodwaters from Gympie approach Maryborough.

On Sunday afternoon, the Fraser Coast Regional Council began removing rails from the bridge as an "appropriate precaution".

A flood of 5.7m will cut the Granville Bridge approach on Kent St while a 5.5m peak will put water over the road on the Lamington Bridge.

On Sunday morning, the flood peak in the Mary River at Gympie hit 16.5m.

That water was expected to finally reach Maryborough by Sunday afternoon, but levels could increase when run-off from local creeks join the Mary River.

Speaking to the Chronicle from the Local Disaster Management Group headquarters in Maryborough, Fraser Coast Mayor Gerard O'Connell said all eyes were on the rising river.

"It's moving quite slowly away from Gympie," he said.

The Bureau of Meteorology was assessing their latest information late on Sunday night to get a better understanding of what would happen in Maryborough.

But more than 200mm of rain that fell in the Burnett west of Woocoo hadn't affected river gauges yet.

"That's yet to join our system," Cr O'Connell said.

While Kent St and the Lamington Bridge were likely to go under, other roads on the Fraser Coast should remain open.

Because all the water is coming from creeks flowing into the Mary River, localised flooding wasn't a concern of the LDMG.

"It hasn't rained here for ages," Cr O'Connell said.

Maryborough Hervey Bay Rd is likely to remain open with Cr O'Connell not expecting Saltwater Creek bridge to be inundated.

"It's not on our immediate watch at this point in time," he said.

Flood mapping on the council's website show a flood of 5.5m would soak the lower end of Kent St and The Pocket.

Maryborough's CBD and its shops are likely to be spared.

Ambulance personnel and other emergency services officers will be stationed at Granville in preparation for isolation.

Once floodwaters recede, the Department of Main Roads will send its engineers assess bridges and roads before they are reopened.
