D6 Water Storage Dam
project overview

Newmont initiated a study in 2016 and concluded that the construction of the D6 Water Storage Dam with a minimum of 6GL storage capacity was required to assist with the expansion of the southern waste dumps at the Boddington mine site.

The dam will provide long term water security and will mitigate the risk of running out of water. The water will be pumped into the D6 Dam from the Hotham River Pump Station No 1 and No 2.
