TRANSCRIPT
BACKGROUND
North Central Catchment Management Authority (CMA) prepared the Draft
Bridgewater Flood Management Plan, with funding from both the state and
Commonwealth governments, in response to the 2010-11 flood events that
had a significant impact on the town.
A community based Steering Committee has overseen the development of
the draft plan, with support from a Technical Working Group that included
representatives from relevant water and flood management authorities,
government bodies and emergency response agencies.
Under the plan, a detailed flood modelling process was undertaken to
determine flood characteristics for a range of flood events, identify key
flooding issues, and explore options to reduce the impact of future flooding
on the town. This process was assisted by community members who provided
valuable local knowledge including flood observations and photos. The
outcomes of the plan are detailed overleaf.
PROGRESS UPDATE
In February 2016, an information brochure on the draft plan was sent out to
Bridgewater residents, inviting community feedback on the preferred
mitigation option of a levee system on the Loddon River.
The feedback obtained by North Central CMA from Bridgewater residents, via
feedback forms and during one-on-one meetings, was overwhelmingly
against the construction of a levee in the town. The plan’s final
recommendations have been revised in response to this feedback.
The Steering Committee
would like to thank all of
the residents of
Bridgewater who
contributed their time
and knowledge to the
development of the plan.
The Final Bridgewater Flood Management Plan will recommend the following actions:
Amendment of the Loddon Shire planning scheme to reflect the improved understanding of flooding
Adoption of new flood levels to inform future planning-related decisions
Adoption of the revised Municipal Flood Emergency Plan to improve emergency response
Development of a VICSES FloodSafe Guide for Bridgewater residents
Regular community information sessions regarding the management of reservoirs
Development of a Total Flood Warning System based on flows through the Laanecoorie gauge
Develop a community flood observers network to inform emergency services during a flood event
Ensure people requiring assistance are registered in the Loddon Shire Vulnerable Persons Register
The final plan will not recommend the construction of a levee system

Bridgewater FLOOD MANAGEMENT PLAN 2016
OUTCOMES FROM THE PLAN
The purpose of the Bridgewater Flood Management Plan was to improve planning for, and reduce the impact of, future
flood events on the town. A detailed flood modelling and planning process has been undertaken in order to achieve
these objectives, assisted by community members who provided valuable local knowledge, including flood
observations and photos.
Below is a summary of the outcomes the plan has achieved on behalf of the Bridgewater community:
FIND OUT ABOUT YOUR PROPERTY
As a result of the study, free property-based flood reports are available via North Central CMA’s FloodEye
online mapping tool. Bridgewater residents can download flood reports for their property at:
http://www.nccma.vic.gov.au/Water/Floodplain_Management/Flood_Eye/index.aspx.
BETTER UNDERSTANDING OF FLOOD RISK:
Mapped a range of flood events, including flood water depth and
velocity, making it easier to predict flood impacts in the future.
Undertook floor-level surveys to understand flood impacts on homes
and businesses.
Created free property-based online flood reports (see below).
IMPROVED PREPARATION MEASURES:
Proposed amendments to the Loddon Shire’s Planning Scheme to accu-
rately reflect the new understanding of flood risk.
Developed improved flood warnings based on flows at the Laanecoorie
gauge, linked to the flood mapping of the town, to allow residents and
emergency agencies to respond to flood threats and minimise impacts
on people and property.
Updated the Municipal Flood Emergency Plan to enable agencies to co-
ordinate their preparation and response activities.
INVESTIGATION OF FLOOD MITIGATION OPTIONS:
Assessed the advantages and disadvantages of a number of structural
flood mitigation options, based on technical and local expertise. Options
included floodwater diversion or storage, improved floodwater passage,
and various levee systems. None of these options will be recommended
by the final plan.
