In 2012-13, Seqwater commissioned an independent assessment of its 26 regulated dams. This assessment included a review of the condition of our dams and their compliance with current Queensland and Australian guidelines, and has identified a program of work needed to ensure our dams meet these guidelines. Under our Dam Improvement Program, we will upgrade some dams and reduce the water levels of others until upgrades can be completed.

Upgrades have been prioritised across the region in a staged program that is scoped and scheduled to maintain water supply security, while delivering best value for money.

Investigations are in progress to confirm the need, scope and timing of upgrades at a number of our dams. It's important to note the timing and need of any upgrades under this program may change depending on the outcome of ongoing investigations.

Dams included in the program are:

Dam Upgrade status
Bill Gunn Dam (Lake Dyer) TBC
Cooloolabin Dam Completed
Ewen Maddock Dam Detailed design and approvals
Somerset Dam Options analysis
Wivenhoe Dam Feasibility studies
Wappa Dam Completed
