Raising the full supply level of Darwin River Dam

Darwin River Dam is Darwin's primary potable water source, supplying about 90 per cent of the water for Darwin, Palmerston and surrounds.

Increasing the reservoir's capacity was a two-year project to reinforce the embankment and raise the spillway by 1.3 metres.

This increases the capacity by about 20 per cent, providing additional supply for the growing population.

The pumpstation and other infrastructure downstream have the capacity to support the additional supply, so raising the spillway at Darwin River Dam was a cost-effective way to meet the increasing demand.
