Goulburn-Murray Water (GMW) is set to undertake winter upgrade works on infrastructure important to the operation of the Stuart Murray Canal at Nagambie.
The canal, located off the Goulburn Weir, is used to transfer water to parts of the Central Goulburn irrigation area and the Waranga Basin water storage.
“The water transfer is controlled by an off-take regulator, which has four radial gates,” GMW Manager Dams Operations Scott Wikman said.
“These gates were installed in 1967 and have come to the end of their operating life. Their replacement will ensure the continued reliability of water delivery to our customers.”
The works, to commence in mid-May with completion expected by early July, will take place during the gravity irrigation off-season and will not affect irrigation customers.
To allow for the works, the Stuart Murray Canal will be drained. To ensure GMW can harvest water during this period, GMW will also temporarily lower Lake Nagambie’s water level by up 50cm or 0.5m during the works.
“The lake was lowered by 0.5m in the winter of 2016 for related work on the Stuart Murray Canal and there was negligible impact on the environment, tourism and recreation during the project,” Mr Wikman said.
“All stakeholders are again being alerted to the lake lowering in advance of this year’s gate replacement.
“When the works are complete, the lake will be returned to its normal level.”
The Goulburn Weir and its adjoining recreational area will remain open and accessible throughout the upgrade; however, for safety reasons, the Stuart Murray Canal’s offtake structure, walkover and adjoining carpark will be closed from May 24 to July 12 2019.
“During the upgrade, residents and visitors may notice an increase in heavy vehicles on the roads around Goulburn Weir,” Mr Wikman said. “There may be minor traffic delays and we ask drivers to be patient and take extra care when using the roads around Goulburn Weir.”
