St George channel flood repairs nearing completion

18 Nov 2014

The final stage of repair work to the Thuraggi Channel in St George is underway after major flooding in 2012 caused significant damage to the civil structure of the watercourse.

During the flood event, the Balonne River broke its bank downstream of Beardmore Dam, where water travelled overland to the Thuraggi Channel and caused large washouts.

SunWater Irrigation Systems Service Delivery Manager Colin Bendall said the $560,000 repairs had been delivered in stages throughout the year, with the final stage due for completion in December.

"Like the rest of St George, SunWater’s infrastructure was hit hard by the devastating floods in 2010 and then again in 2012," Mr Bendall said.

"Our crews have completed about 90 per cent of the work required to return Thuraggi Channel to its original design and full flow capacity," he said.

"This included rebuilding the erosion protection system by carefully removing old rock and concrete and replacing it with new rock mattresses and geofabric underlay.

"We’ve also repaired all side drain drop boxes that were affected by the large flood flows, allowing drainage around the watercourse to work as originally designed.

"Over the coming month, we will continue with remediation of the large washout areas along the first three kilometres of the channel. This will ensure the stability of the banks and maintain the channel’s water quality.

"Despite the conditions being difficult, we are pleased to be delivering this work on time and on budget."
