Flooding and mitigation

Bendigo flood 2007 Back Creek Flora Hill

The City of Greater Bendigo experienced extensive flooding in the past decade due to both creek and localised flooding during the major storm events of 2010 and 2011.

Flash flooding occurs following intense rainfall with resulting flood levels rising to their peak within a very short time, typically between 30 minutes and 2 hours. This tends to occur in steep urbanised catchments such as Bendigo and gives residents very little warning time to prepare.

In addition to maintaining our drainage system, we aim to minimise the impact of flooding by setting building and renovation criteria, providing flooding advice and updating flood information.

If your land is subject to flooding, your development is required to meet our criteria for flooding and we consent to your proposed work.

To check if your property or area is subject to inundation you can find that information in the following maps: 




Water Technology was commissioned by the North Central Catchment Management Authority (NCCMA) in conjunction with the City of Greater Bendigo to undertake the Bendigo Urban Flood Study. This study involved detailed hydrological and hydraulic modelling for Bendigo’s urban areas and its outskirts, including Bendigo Creek and its major tributaries and the overland flow paths.

The flood mapping of the Bendigo Creek Catchment was one of the most technically comprehensive studies ever undertaken in Victoria. Water Technology believes that this study is a landmark study for flood mapping of large urban areas, it is the first of its kind, setting the benchmark for future work of this nature.

This study provides excellent information for decision making at a strategic level by generating comprehensive flood maps across the Bendigo urban area. 

The study report can be found at: Bendigo Urban Flood Study (BUFS)

The Municipal Flood Emergency Plan (MFEP) details arrangements agreed for the planning, preparedness/prevention, response and recovery from flood incidents within the City of Greater Bendigo.


After two stages that involved community consultation, the final selection of mitigation options was made by the study's Advisory Group.

In its final deliberations, the Advisory Group reviewed the collected feedback and results of the consultation in addition to the flood modelling and construction estimates for each option. It considered the final report from the technical consultants and adopted the following options for recommendation to the City for further development/funding:

  • Option 1d which is a combination of levee works on Racecourse Creek and levee works on Bendigo Creek up to Leans Road (see map shown in the project bulletin)
  • Option 9a which is an upgrade to the culverts and floodway at Leans Road
  • Option 18 which is reshaping of Back Creek between Howard Street and Ironstone Road

The City has already applied for and been successful with grant funding under the Natural Disaster Resilience Scheme to undertake the survey and design for the Racecourse Creek levee (part of Option 1d).

The City wishes to thank the local community for its input to the study.

An overlay is a map in a council planning scheme showing the location and extent of special features, such as where land may be subject to flooding.

Their key purpose is to:

  • minimise the effects of overland flows and flooding on new buildings

  • ensure new developments don’t adversely affect existing properties

Overlays are based on the extent of flooding resulting from a 1 in 100 year storm. This relates to a storm event of such intensity, based on historical rainfall data, which has a one per cent chance of occurring in any given year.

Having this information means drainage issues can be addressed at the start of the development process and proposals are properly designed.

The City has finalised the flood mitigation study for Kangaroo Flat and Golden Square. The study presents recommendations with flood mitigation options for the area considering their costs and benefits.  

Based on the study the most feasible option is the recommended modifications to the upstream reservoirs increasing flood storage capacity of Crusoe Reservoir and redirect runoff from between Sandhurst and No 7 Reservoirs into Crusoe Reservoir using a catch drain system. This option has the higher benefit-cost ratio, strong community support and that provides protection to the greatest number of properties, resulting in a significant reduction of flooding and damages associated with it. 

Now that the study is complete the City of Greater Bendigo will proceed to request funding for the functional and detailed design of the preferred option the recommendation. 

The City wishes to thank the local community for its input to the study.
