The river is now swelling with more water than it has held in years, thanks to heavy rain at the weekend and increased environmental flows from dams.

For Jerry Lieben and his wife, Kiwi, who are visiting Wagga from Blayney and staying at the caravan park, the extra rain that fell on Monday night gave them a few concerns.

Mr Lieben said a false alarm had been raised on Monday night and they had been told to evacuate.

He said they had started packing their caravan before the State Emergency Service (SES) told them there was no need to panic.

"Everybody was packing up and getting organised," he said.

Mr Lieben said when he and his wife arrived in Wagga a couple of weeks ago, there had been a sign visible a few metres out from the current water's edge.

"We started getting worried when there was a sign out there starting to be covered with water," he said.

But any concerns proved unfounded, with even the cabins closest to the water remaining high and dry.

The Murrumbidgee River was yesterday expected to peak about seven metres, below the minor flood level.

Release of environmental flows from Burrinjuck Dam are expected to keep the river above 5 metres for about another week at Wagga.

The Bureau of Meteorology is predicting the river will peak at 6.7 metres at Narrandera on Sunday and at 5.5 metres at Darlington Point on September 16.

The SES is warning people living and working along rivers and streams to move stock and equipment to higher ground.

People should avoid walking or driving through floodwaters, and call the SES on 132 500 if they need emergency flood assistance.
