Flood Studies

Through the implementation of the Regional Floodplain Management Strategy, the Goulburn Broken CMA works with Local Government, Victoria State Emergency Service, Bureau of Meteorology, other agencies and the community to develop flood studies.

Flood studies provide information on the nature of flooding for a range of magnitudes – from small to large floods, which may inform flood mitigation, flood warning, land-use planning and emergency management.

Completed flood studies can be found in the Publication page. Draft flood studies can be found below.

Draft Flood Studies

This page provides access to DRAFT studies and mapping to foster input from stakeholders and the community.

These studies are at draft stage and should only be used for the purpose of providing feedback. These studies are subject to change until studies are adopted as final.

The Goulburn Broken CMA in association with Benalla Rural City Council has commissioned consultant Water Technology to carry out a detailed flood study for Baddaginnie.

The aim of the study is to gain an understanding into the nature of flooding for a range of flood magnitudes, provide flood mapping and intelligence to improve future emergency and community preparedness from floods, land-use planning and development considerations and a to consider any potential flood protection measures (high level conceptual review).

The important first step is the data collection phase

We are keen to learn from the community experiences and recollections from past floods

For example, flood photos or details such as: ‘The water was up to the bonnet of my car in the driveway at 1 Palmerston St Street on Friday at 9am in November 2022’ or: ‘The water was at the top of the culvert on the Flooded Road on Wednesday at 7pm in October 1993’.

Community members are encouraged to read the Frequently Asked Questions and Community Questionnaire.

Please return any comments back to us via the following email planning@gbcma.vic.gov.au

Community drop-in session

A community drop-in session will be held on Wednesday 15 April from 4pm-6pm at the Baddaginnie CFA Station, 62 Palmerston St.

Interactive Flood Map

Following the community drop-in session on Wednesday 15 April 2026, the flood study consultant, Water Technology, has prepared an interactive flood map.

The Goulburn Broken CMA is conducting the Goulburn and Broken Rivers Flood Study to provide flood mapping for the Goulburn River from Lake Eildon to Shepparton, and the Broken River from Lake Nillahcootie to Shepparton, including for many areas which have not been flood mapped previously.

The flood study has been calibrated to the 2022 and 1993 flood events, representing the largest flood events in recent memory along the Goulburn River and Broken River and their floodplains respectively.

The community is invited to review the available mapping and provide input into whether the mapping reflects what was experienced during the 2022 and 1993 floods.

To provide feedback or for further information contact planning@gbcma.vic.gov.au  or (03) 5822 7700.
