Recent rainfall has missed Brisbane’s main water supply catchment.
While other catchments in the region were saturated, Wivenhoe Dam largely missed out on the rainfall and is at just 37 per cent capacity.
"So, that's only seen a rise of about 1 per cent in storage capacity over the past week," SEQ Water spokesperson Chris Owen said.
"[That's] the one that we really need the rainfall to fall in because it caters to more than 50 per cent of the region's water supply for south-east Queensland."
Despite the days of rain, experts have asked people to conserve water.
"[People should] try to limit water use as levels trend down and as we head into the traditional dry season of winter," Mr Owen said.
