However, the statewide situation remains volatile, with numerous watches and warnings active following a month of heavy rainfall.
More than 30 people have been rescued from floodwaters since Friday lunchtime. The SES has received more than 745 requests for help.
In the Hunter, major flooding is on the cards in Singleton for Sunday morning, and Maitland is also on alert.
On Monday, the Macquarie River at Warren could also reach high levels.
Areas of major concern include along the Namoi River at Gunnedah, in the state’s northeast, and the Castlereagh River around Coonamble in the central west.
The Bureau of Meteorology said some areas of the state were hit with more than 100mm of rain on Friday.
On Saturday evening, there were major flood warnings for the Lachlan at Jemalong and the Namoi at Narrabri and Wee Waa, where it’s feared residents could be cut off for more than a week.
Sydney’s Warragamba Dam began spilling shortly after 9pm on Friday.
WaterNSW said the outflow volume could peak at a rate of about 60-80 gigalitres per day, just a fraction of levels in March that peaked at 500 gigalitres per day.
“On current projections the spill could continue for up to a week,” WaterNSW said in a statement on Saturday, adding “downstream impacts are likely”.
Premier Dominic Perrottet on Saturday urged residents to follow safety advice and avoid driving through flooding,
The number of flood rescues performed by SES volunteers was “way too high”, he said.
“Those rescues take place in the main because people aren’t following the instructions, they’re driving through floodwaters. Don’t do that.
“Follow the advice, that’s the best way to stay safe.”
