Water levels in Charlton's swollen river are decreasing rapidly as rains ease in the flood affected Victorian town.
The Avoca river has significantly subsided in the past 24 hours, Incident Controller John Breaks said, moving away from the major flood level of 7 metres.
"It peaked at 7.55 metres at 2pm Saturday afternoon and had dropped to 6.6m at noon on Sunday," Mr Breaks said.
With no rainfall expected by Monday morning, the river will likely fall below the moderate flood level of 5m.
But the town will still be on alert, as more rain develops this week.
Rains of 10-20mm are expected in Victoria's northwest late on Tuesday, which might pose a greater risk in Charlton, the Bureau of Meteorology says.
"There is a potential for higher falls depending on how that front develops in the next couple of days," senior forecaster Peter Newham told AAP.
The town will hold a community meeting at 4pm on Monday to assess the risk of flooding.
