More than 150 of Nathalia’s 1400 residents have left the Victorian town after being warned its levee system can no longer be guaranteed to hold back floodwaters.
The State Emergency Service (SES) issued several alerts to Nathalia’s residents on Thursday, warning them to calmly evacuate the town before nightfall due to fears the levee could fail.
By Thursday night, 165 had self-evacuated, said SES spokesman Darren Morgan.
Mr Morgan said while the levee was still holding up, water was coming up through the ground.
Reinforcement of the levee was continuing, he said, but there was a problem with floodwaters backing up through the stormwater drainage system inside the levee.
“While the levee system has not failed at this time, it cannot be guaranteed that the levee system will hold,” he said.
“It’s highly recommended that residents evacuate.”
The water level in Broken Creek was at 3.25 metres on Thursday night, with hydrologists predicting levels to peak at up to 3.3 metres, he said.
“The expected peak is approximately 60-65 centimetres above the 1993 flood level,” said Mr Morgan.
“The water level is not expected to drain below three metres until Sunday.”
Relief centres have been set up at nearby Echuca and Shepparton.
Some 665 properties are at risk of being flooded in the town and four homes have already been inundated.
Shepparton incident control centre spokesman Stan Hendy said the levee should hold but was unstable in some places, as the water has been pushing against it for several days.
If the levee fails, 500 homes on the south side of the creek are at risk of flooding, while 150 homes are vulnerable to the north, he said.
