Monto Road may flood every two yearscould floodtwo-yearly

MOTORISTS can expect the Gladstone to Monto road to flood once every two years, according to the Department of Main Roads (MRD).
MRD has told Calliope Shire Council the road in the Iffley Creek area 'has only a two year ARI (Q2)' which means a one in two year flood risk.
The information was released after Calliope Shire Councillor Craig Butler raised concern in October last year that the road could be flooded or damaged by floodwater.
Cr Butler, who is also a surveyor, had told council there was only 1.2 metres of clearance between the road surface and the water level if the dam reached full supply.
He said if floods overtopped the dam by a metre or a metre and a half, flooding or degradation of the roadway at Iffley Creek and possibly elsewhere could result.
Yesterday Cr Butler said he was 'not entirely happy' that the Monto Road was expected to be flooded once in every two years.
'There are many people who live there who commute to work in Calliope or Gladstone who would be seriously inconvenienced,' he said.
MRD had said it had no plans to relocate the road at this stage because Gladstone Area Water Board (GAWB) believed the Awoonga Dam wall would be raised again within 10 years (to the 45 metre level) which would make the relocation of the road necessary.
However, GAWB chief executive officer Rod Hayes said the MRD appeared to be relying on outdated information.
He said there were no plans to raise the dam wall any higher than it was now.
