The Wimmera River will have a significant flush after rainfall

The Horsham Weir is bursting with water as of Tuesday, February 2.

The Horsham Wetland and boardwalk are completely underwater.

Horsham Rural City Council warned on Monday the river would be "a significant flush" after heavy down pour from late last week.

The Yanga Track is underwater and unable to be used.

More rain is forecast for Friday and Saturday.

Authorities have warned residents to respect the Wimmera River as water levels rise due to last week's downpour.

The Horsham Rural City Council have said the river will have a "significant flush" this week due to heavy rain on Friday and Saturday.

Council infrastructure director John Martin said no houses were likely to be impacted; however, farmers may need to consider moving stock away from low lying areas.

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."

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 70mm was recorded on Friday.

Water was released on Friday when some boards were removed from the Horsham Weir location on the Wimmera River.
