THE flood levee wall at Murwillumbah has potentially been compromised by a land slip overnight.
Tweed Shire Council is working to stabilise the 50m section of the riverbank.
The Council said there was no risk to private property and the slip probably happened because the wet weather.
"This is likely a result of undermining, weakening and saturation of the earth embankment during the January flood," planning and infrastructure engineer Danny Rose said.
"Surface cracking of the levee adjacent to Commercial Rd was observed following that event and we included this issue in the list of restoration works under the Natural Disaster Relief funding arrangements.
"Staff are organising emergency repairs and consulting with NSW Government agencies to facilitate early permanent repair.
"In the short term, council is implementing temporary measures to stabilise the bank, make it safe for Commercial Rd users and to provide armouring should another flood eventuate soon.
"We will make sure that the crest level is maintained through this area, although this may require some temporary measures such as sand bags.
"We will then look at permanent reconstruction works to re-establish levee integrity," he said.
The council informed the State Emergency Service of the levee failure this morning.
