Major concerns were held for the Hawkesbury and Nepean Rivers after the Warragamba Dam spilt over on Saturday morning.
The dam released 200 gigalitres of water into the system downstream every hour.
The Hawkesbury River peaked at 10.52m in North Richmond, far north-west Sydney, about 9pm on Saturday leading to major flooding.
Those levels fell to 8.98m early on Sunday and expected to fall below the moderate flood level of 7.9m on Sunday, according to the Bureau of Meteorology (BOM).
Floodwaters at Windsor, just up-stream, sit above the moderate flood level at 9.35m and is expected to remain steady into the week.
Meanwhile, the Hawkesbury Rivers near Lower Portland continues to rise and is predicted to break the minor flood level of 4.6m.

Hawkesbury mayor, Sarah McMahon, said the community is now stuck waiting for waters to subside.
'Potentially our farmers, home owners and residents who are down on the lowlands will need to see if their properties and their businesses have been impacted,' she said.
NSW SES superintendant Scott McLennan said the agency is working to support the community.
'We are working through a range of warnings as the situation changes,' he said.
'With the peaks of the Hawkesbury-Nepean River passing overnight, we will start seeing the gradual falling of the river and that debris starting to move down stream.
'[Sunday] will be more about supporting those communities that have been isolated.'
