Intense rain on Sunday forced authorities to open the floodgates on the Ross River Dam to relieve pressure, releasing around 1,900 cubic metre of water per second downriver.
The Australian Defence Forces filled sandbags, deployed amphibious cargo vehicles and helped pluck flashlight-wielding residents from their rooftops Monday, as monsoon rains drenched the northern state of Queensland.
The massive monsoonal deluge has caused landslips and flash flooding across the region over the past seven days. "You think there can't possibly..."
Locals also reported several sightings of large crocodiles as a raging torrent of floodwater rips through the heart of the city.
Meanwhile, the Bureau of Meteorology has warned homes near the Ross River are expected to be inundated this afternoon.
Bureau meteorologist Adam Blazak said the heavy downpours could continue until Thursday, while floodwaters would take some time to recede even when the rains lessen.
With up to 500 homes are already under water, a heavy deluge of rain on Sunday pushed levels to nearly 250 per cent capacity with authorities opening the floodgates, nearly doubling the amount of water flowing out of the catchment.
'We door-knocked for three days.
Hughie Morton, 21, and Troy Mathieson, 23, were last seen on Ross River Road near floodwaters in the suburb of Aitkenvale on Monday morning and were still missing that night.
The trough that's been dumping flooding rain on north Queensland's east coast, and drought-hit parts of western Queensland, will drive the state's emergency for days to come.
The TLDMG chose to further open the spillway gates further Friday morning to reduce the risk of significant downstream flooding if further rain falls over the dam catchment in coming days.
On Sunday, the city authorities released a dam which had swollen to double its capacity following a week of record rainfall.
Government officials on Monday warned that floodwaters could also contain crocodiles and snakes, since the animals may move around in search of a "quiet place".
Australian man Andrew Roberts is more anxious about being eaten by a crocodile in his Townsville home than chest-high water surging through the ground floor. On Sunday, the figure was between 400 and 500.
Resident Chris Brookehouse, whose home is flooded, told ABC: "The volume of water is just incredible".
'The modelling says what it is going to say - it could move up to the 10,000, 20,000 [homes].
"That water needs to go somewhere".
"This is unprecedented, we've never seen anything like this before", she said.
