Warnings to cut down water usage have been sparked in south-east Queensland after falling dam levels and the highest usage rates are being recorded since before the 2000s drought.

Dam levels were recorded to be at 70.5 percent last Sunday, whilst the average south-east Queenslander is using 211 litres per month between January and February- 25 litres more than last year in this period.

Although possible heavy rainfalls are predicted, meteorologists are saying there is no strong indication of above average rainfalls over the Autumn period.
