Floodplain Management

Floods play a significant role upon the Wimmera’s landscape. Most Wimmera towns are built around natural water features such as wetlands, rivers, and creeks. During high rainfall events, many community members are impacted directly or indirectly as a result of floods. Flood investigations are undertaken to minimise risks to human life, protect infrastructure, and minimise financial loss across the region. Wimmera CMA work closely with State Emergency Services (SES,) local government, and other emergency management agencies and the community to ensure all floods are proactively managed.

What is floodplain management?

Floodplain management involves reducing flood risk by using the combination of: planning controls, flood mitigation works and maintenance measures, managing flood-warning systems, and predicting flood severity following heavy rainfall.

Specifically, Wimmera CMA’s roles and responsibilities for floodplain management include:

  • determining the extent and height of floodwaters
  • declaring flood levels
  • managing waterways and floodplains
  • raising awareness of floodplain management issues and related best management practices
  • advising local government on flooding issues affecting development
  • developing and implementing plans to minimise flood risk and damage
  • providing specific flood advice to the public and local government for land development and use
  • undertaking flood monitoring
  • obtaining and enhancing flood data
  • providing specialist flood intelligence advice to VicSES and incident controllers during floods
  • assisting local government to develop flood emergency plans
  • assisting VicSES to develop flood warning systems.

Floodplain Management Strategy

The Wimmera Floodplain Management Strategy 2016 is guided by the Victorian Floodplain Management Strategy.

Chapter 17 of the Victorian Floodplain Management Strategy 2016 sets out a series of policies, accountabilities and actions for levees and other forms of flood mitigation infrastructure. Collectively, they define the Management Framework for Flood mitigation Infrastructure in Victoria.

The Department of Environment, Land, Water and Planning (DELWP) has released a series of Guidance Notes aimed at helping those wishing to construct or maintain infrastructure which is all available on their website. This includes:

  • An overview of the VFMS management framework for flood mitigation infrastructure
  • Guidance Note 17.1 Deciding whether to leave flood mitigation infrastructure unmaintained
  • Guidance Note 17.2 Bringing Infrastructure under formal management arrangements
  • Guidance Note 17.3 Designing constructing and implementing flood mitigation infrastructure
  • Guidance Note 17.4 Levee Maintenance Permits
  • Guidance Note 17.5 Deciding whether to use Water Management Schemes to manage flood mitigation infrastructure
  • Levee maintenance permit application kit.

What is the Wimmera CMA doing to help?

Between these events, Wimmera CMA:

  • conducts floodplain investigations to improve knowledge of floodplains in the Wimmera, targeting known high flood impacted areas
  • works closely with Councils to reduce flood risk to properties and buildings through referrals to planning applications
  • works closely with partners including VicSES, Councils, and Government departments to educate the public in floods and floodplain management
  • provides information to the public about individual land parcel risks presented by flooding.
