Barwon River peaks in MungindiBy Catherine Clifford, Thursday February 7, 2013 - 20:30 EDT
Mungindi farmer, Anthony Barlow, says the swollen Barwon River is spilling on to the floodplain.
Between 4:00am and 5:00am the river rose 1cm at Mungindi, from 7.68 metres to 7.69 metres.
At 7:00pm on Thursday the Barwon River at Mungindi had risen to a height of 7.74 metres.
The Bureau of Meteorology's National Flood Desk has predicted a major flood peak of around 7.8 metres.
Anthony Barlow says the water is not travelling rapidly, as it did in Queensland and northern New South Wales, but he says it did come up fairly fast.
"Well, it started to rise very quickly, probably quicker than we're used to out here, and I guess the only thing that sort of happened yesterday was that the levee bank broke into the golf course on the edge of town which is going to be pretty inconvenient," he said.
"You know, we've had a very dry, hot summer and I think it's actually come through a crack in the bank, but it's certainly going out across the floodplain now."
Anthony Barlow says the floodwaters are unlikely to do much damage, but will be great for the cotton crop which, he says, is looking very good.
The Bureau says flooding will extend downstream over the next several days.
It says a peak of 8.5 metres is expected at Mogil Mogil on Sunday.
Preliminary forecasts indicate Collarenebri will reach 6.1 metres on Wednesday, with minor flooding expected at Walgett.
The Transport Management Centre says flooding at Mungindi closed the Carnarvon Highway at Gravelley Creek.
The closure occurred about four kilometres east of the town, temporarily preventing access between Mungindi and Garah.
