ALREADY flat out from two months of relentless rain, Ipswich's emergency services crews are steeling themselves for another flood.
The QT reported at the start of this month that weather forecaster Haydn Walker predicted a repeat in March of the deluge dumped on Ipswich by ex-Cyclone Oswald last month.
On Monday, Queensland Fire and Rescue Service area director Corey Bock said that threat was being treated as alarmingly real.
"Early March - next week - is looking horrible at the moment with 200-300mm and serious flooding," Mr Bock said. "Our swift water rescue guys will be out at places like Gatton and other places likely to flood when that happens."
He said the current widespread rain was not as severe but still caused disruption and anguish across the region.
"The Lockyer Creek and Sandy Creek have gone over in a few places and Grantham is cut in two but it's only minor flooding at the moment," he said.
"Generally around the area there has been one to two inches (25-50mm) so far.
"Lockyer Creek at Glenore Grove and Laidley Creek at Mulgowie is rising but below minor flooding levels and Clarendon, Atkinson and Moogerah dams are spilling."
Falls of between 70-140mm across the Ipswich region in the 24 hours to 9am Tuesday have dam authorities on high alert.
Somerset Dam is currently at 124% and rising. Releases are at a rate of 700 cubic metres per second.
Wivenhoe Dam is currently at 98.3% and rising, with releases being made at a rate of 400 cubic metres per second - to be increased further this afternoon.
Twin Bridges, Savages Crossing and Colleges Crossing are closed and will remain closed until the rain system clears the dam catchments.
Flows from Lockyer Creek, combined with the dam releases will close Burtons Bridge and Kholo Bridge this afternoon. These bridges will remain closed for about one week.
The Bureau of Meteorology is predicting showers tending to rain for Tuesday and similar conditions for the rest of the week.
