Authorities say people in the Castlemaine area are showing strong interest in a flood study.
Castlemaine, Chewton and Campbells Creek suffered from floods several times between 2010 and early last year.
The North Central Catchment Management Authority (CMA) held its first public meeting for the study on Monday night and says about 90 people attended.
The CMA's Damian Wells says the study will take about a year to complete.
"It's really important we go through a very disciplined process to make sure that that flood model is right and that the flood mitigation options that are proposed are considered by the community and then worked through to see if they meet the cost-benefit requirements for funding," he said.
