The Ross River Dam Upgrade project began in late 2005. GHD
was commissioned to complete the majority of these works by
December 2007.
The AUD$110 million civil infrastructure
construction project brought the dam up to current Australian
National Committee on Large Dams (ANCOLD) safety standards.
Key elements of the upgrade works included the
strengthening of the existing 8km embankment, a major structural
upgrade of the existing spillway, installation of three new radial
gates on the spillway crest, construction of a new control
building, roadworks, landscaping and fencing.
The project also increased dam storage
capacity from 219,000Ml to 235,000Ml.
