Curdies Catchment Flood Study

We’re working on a detailed flood study on the Curdies River catchment, including other creeks and waterways, to determine flood levels and extents in the catchment, such as riverine, flash, and overland flooding.

This project is in partnership with the Corangamite Catchment Management Authority and Moyne Shire Council.

The Flood Study will provide detailed modelling and mapping to define flood levels and extents for different rainfall events and assess the potential impact of flooding on properties, roads and other assets.

The project will model historic events and consider the impacts of climate change on flooding, and will determine if we need to add land use planning overlays to the planning scheme based on the mapping.

We’re seeking the public’s help to make sure the study draws on community knowledge and details of past floods. You can help us by sharing your recollections, insights, measurements and images of past flooding events on rivers and waterways as well flash flooding and overland flooding events anywhere in the catchment.  

BACKGROUND

The Curdies Catchment Flood Study will be used by councils, CCMA, SES and other emergency agencies to:

• Inform decisions about flood warnings and emergency response, for example proactively closing roads before they are inundated.
• Update Planning Schemes to ensure that land controls protect properties from flooding and contain increases in future flood risk.
• Inform infrastructure planning, including implementation of structural flood mitigations such as drainage.
• Increase community awareness and preparedness for flood emergencies.
• Update the municipal flood emergency plans, local flood guides and the Victorian Flood Database.

• The Flood Study will help reduce flood risks by reducing threat to life and property and flood-related damages in the catchment.

Following an initial community survey that happened in November 2024 to gather information about past flooding, we will have a second round of community consultation in January-February 2025 to show the calibration and design modelling of flooding, to gather suggestions for ways to mitigate flooding, and to gather other feedback.

A final round of consultation will present the flood damages assessment and mitigation assessments, as well as mapping for a Planning Scheme amendment.
