New maps have been drafted as the first part of a planning study to manage floods in the Burrumbeet Creek floodplain near Ballarat.
The maps will be presented at a community meeting in Miners Rest tonight.
The area has been inundated a number of times in the past few years and the January 2011 flood provided new information on flood levels, which has been used in the draft maps.
Ballarat councillor John Philips says residents are worried.
"We've had three floods over the period of a couple of years ago and very significant floods and each one of those floods were actually higher than the last one, so they tended to be an escalation of flooding and that became a major worry for residents," he said.
