Burdekin Falls Dam – Saddle Dam & Monolith Improvement Project
Building Queensland is leading the Detailed Business Case for the Burdekin Falls Dam—Saddle Dam & Monolith Improvement Project to investigate options for improvement works so the dam continues to meet current best practice standards.
Since its construction in 1987, there have been changes to dam safety standards and hydrological information, and the dam needs improving to reflect these changes.
Burdekin Falls Dam is located 210 kilometres south east of Townsville on the Burdekin River. It is owned and operated by SunWater and comprises a mass gravity dam and three earth and rock-fill saddle dams.
With a capacity of up to 1.8 million megalitres – four times the capacity of Sydney Harbour – the dam supports more than 1000 irrigation, industrial and urban water customers.
The Burdekin Falls Dam—Saddle Dam & Monolith Improvement Project received partial funding in the 2017–18 State Budget. Building Queensland will continue to lead the development of the Detailed Business Case in partnership with SunWater and the Department of Energy and Water Supply. The Detailed Business Case will include an analysis of financial, economic social benefit and deliverability of dam safety improvements.
Proposed improvement works being investigated only include raising saddle dams and spillway abutments, installation of post-tensioned anchors to the dam’s main spillway and abutments and installation of anchor bars at the downstream end of the spillway.
The Detailed Business Case is being developed alongside a number of water-related projects being managed or considered across the Burdekin region to increase the availability of water in the Burdekin Haughton Water Supply Scheme and improve the performance of existing assets.
The Burdekin Falls Dam Hydro-electricity Facility pre-feasibility study and Burdekin Falls Dam Raising projects are separate projects not included in the scope of the development of the Detailed Business Case.

Smithfield Transport Corridor Upgrade
Building Queensland is leading the development of a Detailed Business Case for the Smithfield Transport Corridor Upgrade Project in partnership with the Department of Transport and Main Roads.
The proposed Nullinga Dam site is located on the Walsh River in the Atherton Tablelands and has been proposed as a future water supply to serve growing urban demand in Cairns and to stimulate irrigated agriculture in the region, by supplementing existing supplies.
