This levee project will research, develop and prepare flood information that will improve intelligence to assist with flood preparedness, infrastructure resilience and to improve existing flood management strategies and plans.
Background
After the Spring 2022 floods, the Victorian Government funded Catchment Management Authorities in northern Victoria to research and review strategic levees.
Project aim
The project aim is to provide improved flood intelligence for managing levees located in Victoria, north of the Great Dividing Range. Specifically, the project aims to:
- Identify and categorise levees based on the category definitions adopted for the project;
- Identify those levees including temporary levees which require works ahead of an impending flood and the nature of those works;
- Prepare additional content for Municipal Flood Emergency Plans in order to provide respondents with an improved understanding of flooding and possible actions in light of known levees.
The areas relevant within the Goulburn Broken Catchment includes Campaspe Shire, Greater Shepparton City, Moira Shire and Strathbogie Shire councils.
Mapping
Levees located within the Goulburn Broken Catchment can be viewed on the project mapping portal here: Strategic Levee Categorisation Project
After accessing the portal, zoom in to see levees across northern Goulburn Broken Catchment (north of Avenel). Click a levee to see its attributes.
For further details, see the Levee Category Definitions Table below.
Levee Category Definitions
The levee category definitions adopted for the Levee Categorisation Project are given below.
|
Category Name
|
Definition
|
|
Category 1
C1
|
Those levees that are formerly managed whereby the operation and maintenance of the levees are in place that protect urban centres or defined areas.
|
|
Category 2
|
Those levees that are not managed but provide protection to either:
- Urban centres
- Rural areas where it meets the investment criteria outlined in the Victorian Flood Management Strategy (DELWP, 2016) and where it meets the VICSES threshold to act under the VICSES Act 2005 Section 32AC.
|
|
Category 2 – Type A
C2A
|
Levees which do not require significant work ahead of a major flood and may require periodic monitoring
|
|
Category 2 – Type B
C2B
|
Levees which do require significant work ahead of a major flood, or levees which have known issues (weaknesses) from past floods. Active monitoring is required during a flood event.
|
|
Category 2 – Type C
C2C
|
Location identified for a temporary levee ahead of a major flood. The temporary levee is removed post flood.
|
|
Category 3
C3
|
Levees that provide unverified levels of flood protection to multiple property rural areas.
|
|
Private Levees
PL
|
Levees which have been built by individuals solely for the protection of their own property and assets.
|

Features that can significantly alter flood behaviour during major events.
