Council would like to hear about your experiences, concerns and suggestions and would be grateful if you could complete the submission form. Your responses will help us understand the flooding problems in more detail. Local knowledge and personal experiences of flooding are an invaluable source of data and we appreciate your input.
Cardno, on behalf of Bega Valley Shire Council, is preparing a Floodplain Risk Management Study and a Floodplain Risk Management Plan for the Bega and Brogo Rivers. The adopted Study and Plan aims to help Councils to make informed decisions on how to manage flood risks in the future.
Hard copies of the report are available for viewing at Council’s office and also at the Bega Library in Zingel Place, Bega.
The participation of the community is critical to the success of the adopted Study and Plan, particularly when it comes to floodplain risk management project outcomes.
Tell us about your concerns, comments, submissions and suggestions by completing our online survey by Sunday 5th November. Alternatively, written submission may be made to:
Bega Valley Shire Council
Draft Bega and Brogo Rivers FRMS/FRMP public exhibition

Four community drop-in sessions are planned and each session will involve a 20 minute project presentation with opportunity for questions and private discussion afterwards.
Bega Valley Shire Council engaged Cardno to assist with the preparation of the Bega and Brogo Rivers Floodplain Risk Management Study and Plan.
The Floodplain Risk Management Plan builds on the Bega and Brogo Rivers Flood Study, undertaken in 2014, which identified existing flooding behaviour and flood hazards within the river catchments. The purpose of the Floodplain Risk Management Study and Plan is to identify and recommend appropriate actions to manage the existing, future and continuing flood risks arising in the Bega and Brogo River catchments.
The outcomes of this study can help provide protection of you, your family and your property from flooding.
This may mean there may be works undertaken in the future near your home or work, or you may have to incorporate flood compatible design into any future development, or at the very least you will receive advice and information to assist you in making your home or work ‘flood safe’.
The preparation and implementation of Floodplain Risk Management Plans is the cornerstone of the NSW Government Floodplain Management Programme. Management plans can eliminate the ad-hoc decision making process which has contributed too many present day flooding problems.
The Floodplain Risk Management Study and Plan is the focus of the current project. The purpose of the project was to find an appropriate mix of management measures and strategies to effectively manage the full range of flood risk through an effective public participation and community consultation program.
The outcome will be a plan that details how the existing and future flood risk within the Bega and Brogo Rivers Catchment will be managed.
The Floodplain Risk Management Study identifies a range of management measures and strategies identified not only from available data and reports but also from community consultation carried out during April 2016. A number of the identified options are then evaluated for further detailed investigation that include assessment of cost-benefit, economic, environmental and social impact in a multi-criteria analysis after computer modelling. The highest ranking options are then included in the Floodplain Risk Management Plan for future adoption and implementation.
The Floodplain Risk Management Plan then provides a basis for informed decision making and prioritises implementation actions. The final adopted Floodplain Risk Management Plan also provides a basis for securing external grant funding for implementation projects from the NSW Government Floodplain Risk Management Programme.
Flood management measures and strategies identified by the draft findings include a mixture of:

The Bega and Brogo River catchments have a combined area of approximately 1790 km2, and converge at the township of Bega before flowing into the Pacific Ocean approximately 24km downstream. Both rivers originate in farmland below an escarpment of the Great Dividing Range to the north and west of Bega.
Flooding within the catchment has the potential to impact a number of communities including Bega, Tarraganda, Jellat Jellat, Mogareeka, Tathra, Kalaru and Candelo.
The Bega River borders the township of Bega on its western, northern and eastern sides. The inundation patterns for past floods indicate that Bega Township is mainly flooded by overbank flow from the Bega River. Floodwaters back up from the confluence of the two rivers and spread over low-lying areas.
The Bega Township has a history of flooding from the Bega and Brogo Rivers. In February 1971 Bega experienced a record flood that inundated numerous properties and created significant damages. Another large flood event impacted the area in March 2011. There were also a number of other significant events in March 2012, February 2010 and March 1983.
The 1971 flood event resulted in substantial damage in the town of Bega. It was reported that two people lost their lives, over 50 bridges were destroyed, and the damage was estimated at $7 million, and electricity and telephone lines were out of service. Towns south of Bega were out of water supply as water mains were destroyed. Hancock (i.e. Tathra) Bridge spanned 700 feet near Mogareeka but only six of the fifteen spans remained in place after the flood had passed.
