Lake Moondarra

Mt Isa - Dam repair



To reduce the losses of water from the Lake via the dam wall.


The Lake loses between approximately 5,000,000 litres and 8,000,000 litres of water per day depending on the water level. This is monitored on a daily basis.

Water has to be pumped from another source one hundred and twenty kilometres away to repleace the losses. The cost of pumping per day is an additional factor.

The cost of the lost water is approximately AU$ 4,000.00 per day.
