Kangaroo Flat and Golden Square Flood Mitigation Study

Flooding in Kangaroo Flat 2011

This study initially involved assessing the existing flood risk through the study area using hydrological and hydraulic modelling. Community consultation was undertaken in July/August 2019 and a large number of options were collated suggested by the Community, Council and other stakeholders. 41 of those options underwent preliminary assessment in late 2019.

Of those 41, ten options were selected to proceed to the detailed assessment which included detailed modelling the full range of design events, preliminary costing, desktop environmental assessment, damages assessment and benefit-cost analysis.

A second round of consultation was undertaken in February/March 2020 where the community had the opportunity to provide feedback on the detailed options.

The study recommends the 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 was the most feasible option with the higher benefit-cost ratio, strong community support, provides protection to the greatest number of properties, resulting in a significant reduction of flooding and damages associated with it. Therefore, it is the preferred option.

The recommendation is to proceed to the next stage of design, which will consist of functional and detailed design.

Next steps

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.

More information will be provided to the community in the coming weeks with our mailing list.
