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.
Dam improvements are prioritised across the region in a staged program that is scoped and scheduled to maintain water supply security, while delivering best value for money.
Leslie Harrison Dam upgrade
In 2014, the gates at Leslie Harrison Dam were removed and the water level was lowered to allow us to safely operate the dam, while our investigations continued.
Lowering water levels is an industry-accepted practice to best manage the safety of dams either temporarily or in the long term. Lowering the water level in a dam reduces water pressure and loads on the dam wall, and can also create temporary storage to increase its capacity to mitigate floods. The lowered dam water level will not affect water security in the region.
Planning continues for the upgrade at Leslie Harrison Dam. A recommendation on the scope and timing of the preferred option will be presented to the Seqwater Board in mid-2017, as part of the detailed design and approvals phase of the project. We appreciate the strong community interest in the dam's future and will be sharing the outcome of this decision with you in due course.
