MDBA’s Angus Paton said releases started on May 13 and would be managed to meet demands downstream while also achieving the target water level by June 17.
“The MDBA has been working with Goulburn-Murray Water and Transport for NSW to determine the best approach to support essential maintenance on Yarrawonga Weir and coordinate maintenance works for Mulwala Bridge,” Mr Paton said.
“With the irrigation season drawing to a close we are taking this opportunity to temporarily lower Lake Mulwala to enable asset maintenance outside of peak tourism and recreational seasons.
“This is not a full draw-down of the lake as in 2022, when levels were lowered by 5m. Instead, residents can expect the water to gradually recede over the next five weeks, which may affect the use of boat ramps and access points.
“We are working with stakeholders to minimise the impacts while this essential work is undertaken. Recreational users are advised to check conditions and contact G-MW or their local council for updates on lake access.”
G-MW storage services general manager Alan Shea said works on Yarrawonga Weir would likely proceed in late June.
“Submerged post-tensioned anchor bolts will be inspected to ensure ongoing structural integrity of the weir,” Mr Shea said.
“Once all work is complete the lake will be refilled ahead of the next irrigation season.”
Transport for NSW will keep the community updated on traffic impacts as work progresses.
