Crews are in the final stages of their flood levee repair work along the lower reaches of the Loddon River.
Floodwater lingered in the district north of Kerang for several months last year, inundating homes and ruining farmland.
New ring levees have been built around 24 low-lying farmhouses in the region.
The North Central Catchment Management Authority's (CMA) Damian Wells says more than 200 levee breaches have also been repaired and are now being tested.
"Again, the Victorian Government funded the CMA to get in and repair those breaches to ensure that if there were subsequent flood events that those breaches wouldn't provide a source of weakness for those communities and flood risk to those communities," he said.
