The Bureau of Meteorology is warning far west pastoralists not to expect great flows through the Darling River as a result of flooding in Queensland and northern New South Wales.
There has been record flooding in Queensland, and major flood warning is in place for the Barwon River at Mungindi on the New South Wales border this week.
Hydrologist, Justin Robinson, says much of the floodwaters probably will not reach the Darling River and the Menindee Lakes.
"I think we'll see something coming in but it won't be anything too much for anyone to get excited about," he said.
"Which is probably a disappointment for people especially since it's been so hot and dry out in that area of the world."
Mr Robinson says at this stage, it looks like the water is falling too far to the east.
"We'll sort of monitor the river levels as they come down at the various sites and we'll fine tune our forecasts as they work their way down," he said.
"Really to get significant flow into the Menindee Lakes we need a bit more water coming through the Macquarie, the Castlereagh, the Namoi or the Gwydir.
"They're the ones that really drive the big floods."
