Sydney’s drinking water supply could take a hit as Minns considers lowering Warragamba Dam

The NSW government is proposing changes to Sydney's water security policy to better protect residents in flood-prone areas following another bout of intense flooding. The plan could also shore-up Sydney's supply of drinking water. New South Wales Premier Chris Minns says they are looking at ‘all potential changes,’ including dropping the maximum allowable level on Warragamba. Minns stressed however he would not be able to do that unless he supplements Sydney’s drinking water supply in the meantime. At the height of Saturday’s deluge the equivalent of 80,000 Olympic swimming pools worth of water spilled from Warragamba Dam.
