Flood waters in the Lockyer Valley are starting to recede this afternoon but communities downstream are preparing for conditions to worsen.
Lockyer Valley Regional Council Mayor Steve Jones says water levels are receding in Laidley and Grantham.
However, in the neighbouring Somerset region flood waters are rising.
Somerset Mayor Graeme Lehman says residents have been told to prepare.
"At Glenore Grove on the Warrego Highway it was measured about a metre and a half above the 2011 level." Councillor Lehman said.
"So that water's got to come through our region and that's our biggest fear for those people along the Lockyer Creek."
A muddy torrent swept into Laidley about 8:00pm (AEST) last night.
Residents have reported that the water rose several metres within minutes.
Some people in their homes were pulled to safety by emergency crews this morning and treated by paramedics.
Most roads in and out of the town have been cut off for about 12 hours, but authorities have re-supplied the Laidley evacuation centre where more than 100 people have sought shelter.
Councillor Jones says conditions remain concerning.
"Right here in front of the War Memorial here in the corner of the park at Laidley I'm standing on a bubble in the bitumen which would probably be 15 foot in diameter and two foot high ," he said.
"So you can imagine what's underneath that.
"I just think people need to continue to be safe because certainly right here where we are we have some dangerous circumstances."
There have also been evacuations in the Scenic Rim Council area west of the Gold Coast.
Local Scenic Rim disaster controller Mark Griffin says Mount Tamborine is isolated.
Roads on and off the mountain are closed and there is no power supply.
Mr Griffin says trees have crashed onto a number of homes and other properties have been water-damaged.
He says Lake Moogerah Dam is at unprecedented levels and rising.
"That river flows downstream into the townships of Kalbar and Harrisville," he said.
"We have had a number of evacuations at Kalbar already and Harrisville has also opened up an evacuation centre for those houses likely to be inundated."
