The Wimmera River is expected to receive a significant 'flush' early this week following recent heavy rain in the region.
Horsham Rural City Council Infrastructure Director John Martin said no houses were likely to be impacted but farmers may need to consider moving stock away from low lying areas.
The river peaked below minor flood levels at Glenorchy on Sunday morning, and the Bureau of Meteorology has not issued any formal warnings.
But some rural properties with low lying land may see some impacts from the flush as it passes along the river.
It follows a downpouring of rain in the river's upper catchment area where as much 70 mm was recorded on Friday.
Mr Martin said Wimmera Catchment Management Authority and Council would closely monitor the river's levels.
"It is difficult to predict how quickly the peak may diminish as it gets closer to Horsham, as the dry river surrounds such as billabongs and floodways, may absorb some of the peak" Mr Martin said.
"We will need to lower the weir pool in advance of the flush, but we will aim to return it to normal level as the flush passes.
"This will also mean the river below Horsham Weir will see some modest flows in advance of the flush," he said.
