Emergency talks are underway over the supply of water to towns in southern Queensland that are just a few months away from running dry.

Without a major downpour to top up supplies, The Granite Belt city of Stanthorpe is expected to run out of water by December. 

Southern Downs Mayor Tracy Dobie says local council will launch a new advertising campaign to encourage people to adopt simple water-saving measures, such as turning off the tap while brushing teeth.
