South-east Queensland's largest dam has fallen to its lowest level in more than a decade.
Wivenhoe Dam, west of Brisbane, is the region’s largest drinking water storage and is at a low 36 per cent capacity.
Water authority Seqwater spokesperson Mike Foster says low rainfall over large central dams, and excessive water consumption is to blame.
Based on the current rate of usage, the region's dams could hit 50 per cent capacity by September, which may prompt water restrictions.
"Given where our dam levels are, we're absolutely encouraging the community to look at ways they can conserve and reduce their water use," says Mike Foster.
