Marnoo Flood Study to commence

Published on 14 July 2022


Marnoo residents and businesses will benefit from a flood study starting later this month that aims to enhance the flood resilience of the local Marnoo community by improving the available flood information.

The first stage of the study will commence with a community drop-in session to gather local knowledge particularly photographs of past flooding events in the district.

Northern Grampians Shire Council has received funding from the Australian and Victorian governments to conduct the study in partnership with North Central Catchment Management Authority (CMA). Water Technology Environmental Services (WaterTech) has been appointed to lead the technical component of the study to model a range of flood scenarios to determine what areas are impacted by flood water in Marnoo.

Marnoo residents have been mailed invitations to the drop-in session that will take place on Thursday 28 July from 10am to 12 noon at the Marnoo Recreation Reserve. Residents who are unable to attend the session are welcome to contact the flood consultant Mr Ben Hughes directly at or to speak with Nic Murphy, NGSC Coordinator Engineering Services on 0409 389 032.

Cr Murray Emerson believes the outcomes of the study will be an invaluable resource.

“Thank you to the Australian Government and the Victorian Government for funding this project,” said Cr Emerson.”

“It is an excellent opportunity for the community, Council and the North Central CMA to work in lockstep to improve Marnoo’s resilience and understanding of risk.

“The new findings will help us all be on the same page, not just with regards to emergency management when the next flood happens but also with planning for land use and development, insurance and to simply be better informed about where water is after periods of heavy rain.”

North Central CMA’s Nathan Treloar who is overseeing the study, said local community input will be vital to the development of the study.

“We know from previous flood studies that we’ve helped develop that when the community shares their knowledge and experiences, we end up with a study that’s practical.

“The community has a sense of ownership and confidence about the findings.”

The final report from the study findings will be available in March 2023.
