The Murray-Darling Basin Authority has warned of significant flooding downstream of Hume Dam, if further heavy rainfall events occur.
It's increased daily releases from Hume Dam to 31 gigalitres to manage airspace.
The flow rate will keep Murray River levels similar to what they have been in the past few days - a little above channel capacity but well below minor flood level at Albury.
Murray-Darling Basin Authority acting chief executive Andrew Reynolds said the amount of water released would reflect changing conditions in the catchment.
He said the limited airspace currently available meant that the ability to mitigate high flows was limited.
"There is now a high chance of significant flooding downstream of Hume Dam if further heavy rainfall events occur," Mr Reynolds said.
"We are planning to create more airspace over the next couple of weeks.
"We're actively managing Hume Dam and our river operators are working around the clock to assess new inflow and weather information and manage releases."
That included close collaboration with the Bureau of Meteorology and WaterNSW.

"Our priority is keeping the dam safe, capturing and storing water, and where we can, mitigating floods."
Mr Reynolds said the MDBA was trying to increase airspace to help mitigate the impact of future rainfall events.
"This means that over the coming week, releases from Hume Dam may increase," he said.
"A small rainfall event is forecast on the weekend.
"Releases may change in response to this or any rain."
