Project goal:

Ensuring the reservoir’s storage ability is maintained and further improving the reliability of supply to local residents.


In construction

Delivery Date:

Late April - Early 2020

What’s happening?

We are undertaking work to reinforce the supporting sides of the Kununurra Diversion dam.

On the Wyndham side of the dam, we will be excavating the area downstream of the embankment and installing sand, gravel and rock. This work will improve drainage at this site and provide additional stability to the dam embankment.

On the Kununurra side of the dam, vertical columns of compacted stone material will be constructed to provide further stability to this area. Using these columns will also reduce the environmental impact of the project.

Where is this happening?

This work will occur on the downstream embankments of the dam, which is located near Victoria Highway, Kununurra. Please refer to the map for further details.

Why is this work taking place?

To strengthen the structures supporting each side of the Kununurra Diversion Dam and ultimately ensure reliability of water supply to farmers in the Ord Irrigation Area.

When is this happening?

Late April until early 2020.

How will this impact the community?

Overall construction impacts

A significant quantity of material will be delivered to the dam embankments to complete this work and there will be construction vehicles regularly entering and exiting these areas for the duration of the work.  

We advise that the community keep away from these areas for their own safety.

At the completion of the work, there will be a new viewing area constructed on the Wyndham side of the dam. This will allow the public to park safely and view the iconic Kununurra Diversion Dam. We will keep the community updated on this work.

Additional traffic along Lake Argyle Road

As part of this work, large trucks will be carting construction materials along Lake Argyle Road, during daylight hours from Wednesday 17 July until the end of October, 2019. Please refer to this information for further details.

During this period, please take care when driving along Lake Argyle Road and consider the following:

  • Read and adhere to all traffic signage and traffic management.
  • Maintain a safe speed at all times.
  • Slow down as required when approaching oncoming traffic.
