The Shire of Carnarvon has recently completed routine maintenance works on the town’s flood mitigation levee system as part of its ongoing commitment to protecting the community during heavy rainfall and river flooding events.
Rain Off-Shoots Repairs
During the annual levee inspection, crews identified a failed rain off-shoot, which had deteriorated following several years of heavy rainfall. To restore the integrity of the levee, the damaged section was excavated down to a solid base and rebuilt using cement-stabilised soil. The off-shoots were also extended further down the slope to reduce the risk of future damage.
Additional rock was strategically placed in the area to slow water flow and minimise erosion, helping to improve long-term resilience during significant rain events.
Levee Stock Gates Maintenance
The town’s levee defence system includes several stock gates that play a critical role in managing water movement during wet weather and flood conditions. These gates are typically left open to allow rainwater to drain outside the levee system. In the event of high river levels, they are closed to prevent river water from entering protected areas.
As part of regular maintenance, stock gates are inspected twice each year, with checks carried out on seals and overall operational performance. Vegetation is also cleared from upstream and downstream areas to improve water flow and reduce the risk of blockages.
The Shire will continue to undertake regular inspections and proactive maintenance of the levee system to ensure it remains effective and ready to respond during extreme weather events.
