To be confirmed

Raising the current Wyangala dam embankment and downstream rock fill has been proposed to add an additional 650 gigalitres of storage to the dam. It would also raise the spillway and intake towers of the dam by 10 metres.

An increase in the dam storage capacity of 53 per cent is estimated to result in improvement in drought resilience, water security, flood attenuation and water reliability for the Lachlan River.
