AS THE clean-up effort gathered pace in Creswick, residents began asking whether man-made conditions could have exacerbated the floods.
Some residents believe tree planting in the Creswick Creek may have impeded the water's flow and intensified the flood on the weekend.
The council will begin to investigate whether tree planting in the waterways is worsening the flood.
"Council is aware of community questions about the Creswick Creek following the floods and will be working with the relevant government authorities responsible for the management of our waterways to look at the issues," Hepburn mayor Janine Booth said.
But Creswick resident Barry Yates said locals had been concerned about tree planting in the creek for several years.
He said many residents believed trees planted in the creek had caught debris washed down in the floods, causing the creek to flow into the town.
"It's a reasonably general consensus with a lot of people that I've spoken to," he said.
Another Creswick resident, who declined to be named, said tree planting had narrowed the creek, disrupting its flow.
"There's no doubt that the narrowing of a waterway is going to create a problem," he said.
According to Hepburn Shire Council figures, 133 properties were affected by the flooding in Creswick, Clunes, Allendale and Kingston.
Community recovery centres had been set up in Creswick and Clunes, which will operate on alternate days until the end of the week.
Yesterday large skips were taken to Creswick and Clunes for residents to dump household items destroyed by the floods.
However, it was not known how many houses were rendered uninhabitable by the floodwaters.
