Major repair work is underway at Lavertys Gap weir in Mullumbimby to repair serious erosion along the creek bank.

As part of the repair work, a helicopter will be operating in the area of the weir and Wilsons Creek Road on Thursday, 6 November and Friday, 7 November.

The helicopter will be lifting large boulders into place as part of the protections being created on the eroded area.

Residents may notice some noise from the helicopter throughout the two days of operation.

This work is dependent on weather conditions and may be rescheduled if weather conditions are not suitable.

Lavertys Gap weir is an active construction site, and access to the area by land or by water is strictly prohibited.

The erosion being repaired, on the bank at the southern end of the weir wall, has been progressing for some time and was worsened during the 2022 floods and Cyclone Alfred earlier this year.

Byron Shire Council Acting Manager Utilities Dean Baulch said the work at the 100-year-old weir on Wilsons Creek will protect and preserve one of the Shire’s most important heritage assets.

“Without repairs, there is a risk of channels forming in the earth around the weir wall, causing leaking.

“NSW Public Works will carry out repairs that will preserve the heritage fabric of Lavertys Gap weir and secure its long-term integrity,” Mr Baulch said.
