$1.25m project starts on dam wall

A $1.25m dollar project to upgrade Stanthorpe's Storm King Dam started this week.

The work, which is to strengthen the dam wall to withstand a one-in-100,000 year flood, raised questions when it was ordered by State Government.

While the state will pick up 40 per cent of the bill, it will still cost ratepayers $750,000.

Southern Downs Regional Council engineering director said residents shouldn't be worried about the dam's safety.

"The dam, currently, is capable of withstanding any major floods that is likely to occur in its lifetime," Mr See said.

"However, the State Government has decreed that because it is upstream of Stanthorpe, it must be able to withstand a one-in-100,000 year flood," he explained.

"Such a flood is unlikely to occur, however, should it occur in the future these works will ensure that the Stanthorpe community will not have to worry about the dam failing."

Rock anchors and dowels (rods) will be installed into the wall of the dam to safely pass 100% of Queensland's Acceptable Flood Capacity specifications.

Council has contracted Geotech Pty Ltd, a structural engineering company specialising in post tensioning work, to anchor steel cables vertically through the dam wall into the bedrock.

The project must be completed by June 30.

Storm King Dam supplies the drinking water supply for Stanthorpe.

This work is not expected to interrupt the Stanthorpe water supply.
