In 2012-13, we commissioned an independent review of our 26 referable dams, which found improvements are needed at a number of our dams to meet the Queensland dam safety guidelines into the future.

We have prioritised a program of dam upgrades in a staged approach to give us time to scope, design and plan, while maintaining public safety, security of water supply and delivering best value for money.

Wappa Dam is one of a number of dams identified for upgrade in the next six years.

Wappa Dam upgrade

The upgrade started in late September 2016 and due to unexpected delays is now scheduled for completion mid-February 2017.

The project involves modifications to the embankment and spillway, as well as the installation of new filter drains. The dam has remained operational during the upgrade.
