Kununurra & the Ord irrigation area

We'll be undertaking a package of renewal and maintenance works to our irrigation assets in Kununurra between November 2018 and March 2019.

In addition to our regular maintenance work to the Kununurra Diversion Dam, we will also be undertaking a $4.1 million project to install a new gantry crane.

Our work will result in changes to the water levels in the Ord River.

If would like to be notified prior to significant changes to water levels in Lake Kununurra or the Ord River, please sign up to receive our email notifications. Email kununurradepot@watercorporation.com.au to submit your contact details.

Between 1 November and 1 April, wet season operations are in progress. During this time, customers will experience fluctuating water levels in the Ord River in Zones 1 (Lake Argyle), Zone 2 (Lake Kununurra) and Zone 3 (Lower Ord) due to seasonal conditions.

Lake Kununurra will operate between 39.50 metres AHD to 41.75 metres AHD (please note that 41.75 metres AHD is the full supply level of the Kununurra Diversion Dam). On occasions, Lake Kununurra may drop below 39.50 metres AHD as the Kununurra Diversion Dam gate settings are adjusted to compensate for extreme seasonal flows.

If you have pumping or other ancillary equipment in the vicinity of the Ord River, or are required to navigate the river, please consider the risks involved and the preventative measures that need to be taken.

We will lower the level of Lake Kununurra for two weeks, between Monday, 4 February and Monday, 4 March 2019.

The water levels will be lowered during the wettest part of the four-week period so the impact to customers is reduced as much as possible. During this period the level of Lake Kununurra will be lowered below 39.50 metres AHD.

Customers will be informed prior to the exact date of the lowering our email notification process.

What do I need to do?

If you have pumping or other ancillary equipment in the vicinity of the Ord River, please consider risks and preventative measures that may need to be taken.

Boats and barges on Lake Kununurra, Packsaddle and Crossing Falls will need to be removed from the water as securing them will not be sufficient.

Boats in Lilly Creek Lagoon may remain in the lagoon provided they are properly secured as once the water recedes they will sit on the river bed.

We are completing a $4.1 million project to install a new gantry crane at the Kununurra Diversion Bridge, which is located under the Victoria Highway.

The crane will be installed in mid-2019. We will provide further updates on this work via our website closer to the date of construction.
