This council led project will map flooding throughout the Stawell township to inform design any infrastructure needs to manage water flows into the future.

Project Timeline

Step 1.Collect Data

The initial stage of the flood study is to collect data which can be utilised to inform the hydraulic models. Furthermore, a preliminary flood model depicting the Stawell flood event from 2011 has been produced by WaterTechnology. Council is looking for community feedback to confirm the model's accuracy. The data the council is looking for includes:

  • Any photos from the 2011 event 

  • Observations or remarks about the accuracy of the model 

  • Any suggestions for flood mitigation for future events 

The draft 2011 flood mapping can be viewed at this link.

Members of the community can provide feedback via any of the following methods: 

  • Online using the link to POZI 

  • In person at the Stawell Town Hall from 25 September 2023 to 6 October 2023, which there will be large maps available for viewing to assist information provided.

  • By mail to Northern Grampians Shire Council, C/ Stawell Flood Study, PO Box 580, Stawell VIC 3380  

  • By email to ngshire@ngshire.vic.gov.au  

  • A drop-in session between 11am and 1pm at the Stawell Library Multipurpose Room Hall on Friday, 6 October 2023.  

Est. September 2023 – October 2023 

 

Step 2.Flood Level Survey

Some members of the community will be approached by Council to have the floor levels of their homes surveyed. This information is used to identify which dwellings may be at risk of inundation. 

Est. Late 2023 - 2024 

 

Step 3.Develop Flood Maps and Flood Mitigation Options

Using the information provided by the Community, WaterTechnology will create flood maps and investigate flood mitigation options. The community will have the chance to offer suggestions for the final report. Closer to the date, more options for providing feedback will be made available.

Est. Early 2024   

 

Step 4.Finalise Flood Study

A report along with flood maps summarising the findings of the study will be provided to the community. More details for providing feedback will be made available closer to the date.
 

Est. Early 2024 to mid 2024.
