Overview

The floods of 2010-11 caused significant damage to towns and communities across north central Victoria.  The North Central CMA received Victorian Government funding to work with communities and local government authorities to develop flood management plans and studies for some of the worst affected towns.

The flood management plans and studies provide improved flood intelligence and information to enable the North Central CMA to assist Vic SES to provide more accurate and meaningful flood predictions. Each of the plans also identified options to reduce the impact of future flood events for towns and communities. 

The development of each plan had a strong community focus to ensure that the recommendations to local shires and councils met the community's needs. A community based steering committee and technical working groups were formed to oversee the development of each plan.

Bendigo Urban Flood Study

In July 2011, the North Central Catchment Management Authority (CMA) in partnership with the City of Greater Bendigo appointed specialist hydrologic consultants Water Technology to undertake a flood study for the urban areas of Bendigo.

The Bendigo Urban Flood study area includes the Bendigo Creek catchment from Kangaroo Flat to Huntly, including the outlying suburbs of Maiden Gully, Strathfieldsaye and Junortoun.

The study provides detailed flood information for a range of flood events, assists future land use planning and development decision, assists authorities and the community to prepare for and respond to flood events, and assists the prioritisation of future drainage investments.

Bridgewater Flood Management Plan

North Central CMA, in partnership with the Loddon Shire Council and Water Technology, has developed the Bridgewater Flood Management Plan.

The plan focussed on simulating flood events from 2010 and 2011 in the vicinity of Bridgewater to verify the results of a flood model. This model was used firstly to determine flood extents, depths and velocities for a range of event probabilities and secondly to investigate the potential for structural and non-structural mitigation measures to reduce the future risk of flooding to the residents of Bridgewater.

This information was used to make recommendations including:

  •  Updates to flood emergency planning;
  •  Potential amendment of flood-related overlays in the planning scheme; and
  •  Application for funding of flood mitigation works.

The development of the plan was overseen by a community-led steering committee. Community knowledge regarding flooding from the Loddon River and Bullabul Creek was crucial to verify the flood extents and for identifying potential flood mitigation options to test.

Carisbrook Flood Management Plan

The Carisbrook Flood Mitigation and Drainage plan was completed in 2013 and was developed by the North Central CMA and Golden Plains Shire in consultation with the Carisbrook community, after 250 homes were inundated in the January 2011 floods.

Recommendations include a package of works aimed at reducing the impact of flooding on the vast majority of the town up to and including a flood that has a one per cent chance of occurring in any year, like the 2011 event.

Castlemaine, Campbells Creek and Chewton Flood Management Plan

The Castlemaine, Campbells Creek and Chewton Flood Management Plan is now complete. The plan provides 10 recommendations which can reduce the community's exposure to flooding.

The plan recommends the construction of a new levee, the upgrade of two existing levees, undertaking minor waterway improvement works in Campbells Creek and developing an ongoing management plan for urban waterways. It also recommends developing a flood warning system and updating the Mount Alexander Shire Planning Scheme.

The plan recommends council undertake further investigation and consultation for mitigation options in the Gingell Street area. 

North Central Catchment Management Authority (CMA) led the development of the plan, with support from Mount Alexander Shire Council, technical contributions from various statutory agencies and input from community representatives.

Technical work has been undertaken by specialist water consultant GHD. The project was jointly funded by the Australian and Victorian governments, Mount Alexander Shire and North Central CMA.

Charlton Flood Management Plan

The Charlton Flood and Drainage Management Plan makes a number of recommendations to reduce the future risk of flooding to the residents of the town.

These recommendations include improved flood warnings, the construction of flood protection levees around town and undertaking road works to reduce the impact of an existing culverts on St Arnaud Road.

The plan was put to the Buloke Shire Council for its endorsement in April 2013.

Creswick Flood Management Plan

The Creswick community experienced three separate flooding events during late 2010 and early 2011 causing significant damage to property and stress and hardship for many Creswick residents.

The Creswick community experienced three separate flooding events during late 2010 and early 2011 causing significant damage to property and stress and hardship for many Creswick residents. The Minister for Water announced funding for the Creswick Flood Mitigation and Urban Drainage Plan on February 9 2011, with the plan to include the following:

  • A review of the available data, including data from the Creswick Community.
  • Calibrated computer models for the catchment and results for a series of design events.
  • Development of a series of flood and urban drainage mitigation options to reduce flood risk and an assessment of their feasibility.
  • Recommendations of preferred flood and urban drainage mitigation options for consideration by the Steering Committee, Technical Working Group and the Creswick community.

The North Central CMA, in conjunction with the Hepburn Shire Council and the community, has developed the Creswick Flood Mitigation and Urban Drainage Plan.

Clunes Flood Management Plan

The aim of the Clunes Flood Mitigation and Urban Drainage Mitigation Plan was to undertake flood modelling and identify works and actions that could reduce the future risk of flooding to the town. It was identified that a series of flood protection levees could provide a level of flood protection. 

However, North Central CMA received overwhelming feedback from the Clunes community it did not support the construction of levees. The main reasons included:

  • Height of the levees would mean the visual amenity of the town would likely be impacted;
  • Levees could not protect against all flood events;
  • Levees would increase the risk of flooding on upstream properties, which resulted in levees being required behind properties that were not previously flooded;
  • Not all properties could be protected.

North Central CMA received one-off emergency funding to remove the exotic vegetation that blocked the main waterway through town - Creswick Creek. Flood modelling showed the removal of vegetation is likely to reduce future flooding by around100mm to 200mm.The feedback from the community has been that they support improved management of Creswick Creek.

Other recommendations included:

  • Resolving ongoing management of Creswick Creek;
  • Updating Council's planning scheme overlays; and
  • Working with Council, VicSES and the community to improve flood preparedness and emergency response.

Heathcote Flood Study

North Central CMA, in partnership with the City of Greater Bendigo and BMT WBM, led the development of the Heathcote Flood Study. The study provides a better understanding of the existing flood risk and valuable information for the township, particularly for future growth planning.  A range of flood event probabilities were assessed in the study, with resulting updated flood extents, depths and velocities to inform the following:

  •  Updates to flood emergency planning; and
  •  Potential amendment of flood-related overlays in the planning scheme to inform future decision-making.

The development of the plan was overseen by a community reference group who provided valuable local knowledge to verify historical flooding extents.

Rochester Flood Management Plan

The Rochester Flood Management Plan is now complete. The plan has determined flood levels and flood extents for a range of flooding scenarios and provides valuable information that will be used to improve flood warnings and emergency response activities for Rochester. 

A detailed assessment of a range of mitigation options was undertaken and mitigation options were assessed against a number of criteria including potential reduction in flood damage, cost of construction, feasibility of construction, environmental impact and community support.

After significant consultation with the community and stakeholders the plan recommends:

  • Further assessment of a package of works that will provide significant reduction in flood risk across a range of events up to and including the 0.5% AEP event at a total estimated cost of $1.8 million (note: excludes any land easement and compensation costs that may be associated with the recommended works).
  • Staged implementation of a flood warning system for Rochester as described in Section 9.
  • Detailed planning and design of a formal levee to replace irrigation channel 1/1 to the south of Rochester which is marked for decommissioning.
  • Update of the planning scheme to incorporate updated flood overlay.

In summary, the proposed structural works need further investigation so their full impacts can be better understood and conveyed to the community. 

This project also provided the required flood intelligence for revised Appendices relating to Rochester for the Municipal Flood Emergency Plan
