Both Premier Anna Bligh and Liberal National Party leader Campbell Newman will meet Charleville locals today, after flood waters peaked yesterday well below forecasts.

Despite more rain predicted today, the waters are starting to recede in Charleville. However, some parts of Queensland remain on high alert with predictions of 100-200 millimetres of rain in the next three days.

The Bureau of Meteorology predicted flood waters would peaks in Cunnamulla and St George over the next few days, although they said it was hard to predict exactly where the rain would fall.

Senior forecaster Peter Otto said flood levels similar to the 2010/11 summer were possible.

"It's hard to pin down any particular spot where that could happen but there will be major flood peaks in south west Queensland in the next few days," he said.

"There will be clusters of heavy falls pretty much west of the range."

A temporary flood barrier has been flown to Charleville from the Gold Coast and is being erected this morning by the SES.

The barrier is 500 metres long and 200 metres of it has arrived in the town. It is being used as a precaution due to rising flood waters in the Warrego River.

A spokeswoman for the bureau said Charleville had peaked about a metre below expectations yesterday.

"The threat has passed and there was a better outcome than we thought," she said.

Deputy Police Commissioner Ian Stewart used Twitter to say a man who had gone swimming in flood waters in Charleville was fined $300 for public nuisance after "emergency services put their lives at risk to save him".
