THE clean-up from last January's Victorian floods is expected to continue well into this year - and perhaps into next.

This week marks the first anniversary of the floods, which affected more than 100 towns in 70 local government areas.

Caused by a dump of 100-300mm of rain across central and western Victoria, flood water covered a fifth of Victoria, inundated more than 1700 houses, damaged hundreds of roads and affected more than 100,000ha of farmland.

Charlton was one of the hardest hit towns, with more than 400 properties flooded and much of the town evacuated.

Buloke Shire mayor David Pollard said most council facilities had been repaired.

"Repair work on most public assets is nearing completion, including our shire offices, which we will hopefully move back into in the coming weeks," Cr Pollard said.

"We have estimated the damage to our road network at $20 million, and will hopefully begin work on resealing and repairing the roads by March."

Cr Pollard said some residents still faced a long road to recovery and the council continued to conduct door knocks to check on citizens.

Last January's floods and those in September 2010 caused significant damage in Hepburn Shire .

Flood recovery manager Jenny Browne said damage was shire-wide.

The hardest-hit towns of Clunes and Creswick were recovering.

"To date, approximately 50 per cent of flood works have been completed and the balance we hope to complete in the next six to eight months." Ms Browne said.

Gannawarra Shire was one of the municipalities hardest hit by the floods.

It faced an estimated bill of $15 million for the rebuilding of roads and several more millions for bridge repairs.

Until last month, the council had spent $9.8 million on flood-damaged roads.

More than 180km of gravel resheeting and 650km of road grading has been completed in the past year.

Campaspe Shire councillor Frank Oliver said rebuilding infrastructure was well under way across the shire and the worst-affected town of Rochester.

"Restoration works ... are expected to take through to June 2013 to complete," Mr Oliver said.
