Police have confirmed a body has been found in South Murwillumbah as severe floods sweep through northern New South Wales.
The body of a woman was found around 8am on Friday on a flooded property 20km south of Murwillumbah after she disappeared from Upper Burringbar on Thursday night, according to a statement released by NSW Police.
Flood levels reached three metres in Lismore's CBD and the town's levee was overflowing and at risk of collapse after it received 628mm of rain over the past 48 hours as at 3pm on Friday.
The area is set to be declared a disaster zone, the Northern Star reports.
More than 100 calls for rescue in flood-stricken northern NSW remain outstanding since Thursday night.

The Wilsons River in Lismore also reached its peak at 11.57 metres and the Richmond River was also affected, reaching a peak at Kyogle of 17.33 metres.

Northern New South Wales is the latest region to be affected by the tail of ex-Tropical Cyclone Debbie, with low-lying areas on the northern Gold Coast, Beaudesert and Logan regions evacuated as drainage systems fail to cater for the torrential rainfall.
In Lismore, torrential rains caused the town's levee to crack and overflow, resulting in gushing torrents drowning the town's CBD in almost three metres of water.
Sirens sounded throughout Lismore on Friday morning warning residents to leave immediately, after floodwater topped the city's levee. It is believed up to 130 residents were unable to evacuate and were left behind.
"It's too late for us now. So we won't be sending anyone in now. This is a very, very serious situation. We cannot help in the present situation," SES spokesman Ian Leckie told ABC radio in the early hours of Friday morning.
