Winter Works

*Updated 23 September 2020 

Our 2020 winter works program is now complete.  Throughout the winter our teams have worked with customers to deliver a range of works including the installation/replacement of 24 outlets, 14 regulators, 3 escapes and 7 bridges.  In addition, we maintained and repaired over one hundred kms of channel (including 30kms of channel bank raising), as well as 4 major structures - all with no injuries and only minor delays in response to some welcome rain across the season.
This winter the program incorporated expansion, repairs and scheduled maintenance to irrigation infrastructure across the region including structures on the Main Canal and Sturt Canal, as well as on Lake Talbot, the final stage of the Lake View Branch Canal Expansion and repairs at Gum Creek Road and Mirrool Creek Escape.
Of course while winter is over you will still see our teams out and about as we tidy up work sites and move into our regular 'in-season' program.  

A snapshot of the works is included below:

Lake View Branch Canal Expansion

The 2020, and final, component of LVBC expansion project works included: 30 kms of channel bank raising ,7 bridges replaced, 12 new regulators and the automation and upgrade of outlets. This year’s program of works was also broken into three stages to ensure limited impact on customer access to water during the construction phase. The works will provide a more responsive system, better equipped to adapt to changing conditions.

Sturt Canal AFFRA works

We installed X-Path AFFRA Meters and Cableway near the Sturt offtake. These new meters will provide a backup for the current meters and improve accuracy during periods of low flows. The works were aligned with Water NSW’s annual maintenance works at Gogelderie Weir to minimise any additional impacts on supply.


Sturt Canal: New meters, cableway, and some channel bank repair works on the right bank.

Main Canal works

The Main Canal works program included canal relining, maintenance on Roaches Regulator gates, outlet installations and removals, 2 regulator upgrades, gate replacements at Yenda storage facility and works on the supply reaches.

Maintenance and automation upgrades

Sections of some channels where there were no works were lowered intermittently over the past few months to allow for inspections and programmed maintenance and automation upgrade works. These works included outlet installations and removals, channel bank repairs, desilting and pump shed maintenance.

Lake Talbot works

Channel bank repair works and access maintenance, including tree pruning and overgrowth removal, were carried out over the past month. Construction works including a regulator upgrade with an automatic gate, are on hold, and now likely to be held off until 2021.

Penfolds bridge removal

We removed Penfold’s bridge in July, which has significantly improved the flow in this section of the Main Canal. Griffith City Council is planning future works to construct a shared pathway on the opposite side of the road as part of their Griffith Pedestrian & Bicycle Strategy.

Leeton Shire Council’s upgrade of a bridge on the Whitton-Darlington Point Road is scheduled for completion October 2020, with minimal impact to supply.
