Our team has been involved in extensive Studies on;

​

• Lakes Julius and Moondarra; the two water supply reservoirs supplying the mining city of Mount Isa in Queensland.

​​

• Darwin River Dam and Manton Dam; water supply reservoirs supplying Darwin the capital city of the Northern Territory.

 

• Lake Argyle; Australia’s largest freshwater lake/reservoir in northern West Australia used mainly for agricultural irrigation purposes and water supply to the town of Kununurra, the regional centre of the Kimberly.

 

• Lake Wood; the largest natural lake in the Northern Territory and an extremely important environmental feature of Australia’s arid zone.
