The State Emergency Service (SES) has confirmed the Hawkesbury River at Windsor reached a peak of 9.07 metres this morning, narrowly avoiding engulfing the Windsor Bridge.

The Bureau of Meteorology (BoM) has maintained a flood warning for the Hawkesbury-Nepean Valley with more rainfall expected today.

"Flooding is continuing across the Hawkesbury Nepean Valley due to heavy rainfall Wednesday night and Thursday," the BoM said.

"Further showers are forecast during Saturday, which are not expected to produce renewed river level rises."

Warragamba Dam, the main dam in the catchment, is continuing to spill which is not aiding the flood crisis in the region.

The SES said flooding will continue at North Richmond and Windsor today despite the water levels slowly receding.

There were more than 280 calls to the SES for help in the past 24 hours.

There were also nine flood rescues.

The Nepean River at Camden Weir fell below the minor flood level of 6.8 metres on Friday night.

Camden saw unprecedented flood levels this week, leaving residents shocked by the disaster.

Resident Larry Burke experienced the 1988 floods and said he has never seen three rounds of flooding in the town in such a short period of time.

"This is the first time I have seen it come up three times so close together," he said.

"I have not seen that before."

Now, Camden residents are able to return home and assess the damage of the devastating floods.

The flood crisis has turned deadly in Sydney's north-west.

Father-of-two Tony Ikin was identified as the man found dead in Sydney floodwaters yesterday.
