The Murray State Emergency Service has revised its minor flood warning for the Murray upstream of Lake Hume.
The SES says 115 millimetres of rain has fallen since 9am yesterday.
But unlike the initial warning earlier today, the SES now says no significant rainfall is forecast for the rest of Thursday.
The Murray River at Biggara should have peaked at the minor flood level of two metres by now, and downstream, at Bringenbrong, areas of minor flooding at the three metre level are expected from early afternoon.
The SES says riverside pastoralists and campers should act to ensure the safety of themselves and or livestock and machinery.
Meanwhile, the Murrumbidgee SES controller does not expect major flooding in the lead up to the anniversary of the devastating 2012 floods in the Riverina.
But James McTavish has warned flash flooding is possible today.
He says rainfall has been very low for the last three months, unlike the very wet catchment last year when big rains fell.
"There's a severe weather warning for quite a deal of inland NSW for flash flooding at the moment," he said.
"And it doesn't really matter what the catchment conditions are, if you get four inches of rain in a very short period of time, you're going to get run off. But the widespread flooding that we saw last year, while it's not impossible, is certainly much more unlikely than this time last year."
