This is not a full drawdown of the lake as in 2022 when levels were lowered by 5 metres. Residents can expect the water to gradually recede 1.5 metres over the next five weeks, which may affect the use of boat ramps and access points.
The lake is emptied every three to five years to control the invasive waterweed on the lake bed, but this time, the lowering will only be short and sharp for maintenance.
Murray–Darling Basin Authority (MDBA) Acting Executive Director of River Management Angus Paton said releases would be managed to meet demands downstream of the Lake while also achieving the target water level of 123.3 metres AHD by June, 17, 2024.
“The MDBA has been working with Goulburn-Murray Water and Transport New South Wales 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.
“We are working with stakeholders to minimise the impacts while this essential work is undertaken. Recreational users are advised to check conditions and contact GMW or their local council for updates on Lake access.”
Goulburn-Murray Water 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 the 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 New South Wales will keep the community updated on traffic impacts as work progresses.
