About the Study PDF Print E-mail

Flooding causes an estimated $314 million dollars' worth of damage each year and causes more annual damage than any other natural disaster in Australia. Over 2,000 people have also lost their lives during floods in Australia since settlement. As such, flooding can place a significant financial burden on communities and place lives at risk.

Wingecarribee Shire Council is currently preparing a flood study for the Nattai Ponds catchment which includes the townships of Braemar, Willow Vale and Renwick. The study will help Council to better plan, predict and manage the risk of flooding across the catchment. It is part of a series of flood studies being completed across the Shire as part of Council’s Floodplain Risk Management Program, which aims to reduce the impact of flooding on the community.


The extent of the Nattai Ponds catchment is shown in the image in the top right of this page. It incorporates a number of unnamed tributaries, which flow past many residential and rural properties in and around Braemar, Willow Vale and Renwick. Accordingly, there is potential for damage, inconvenience and risk to life during large floods within the catchment.

As part of the study, computer models will be used to simulate flood behavior across the catchment. For the study to be as reliable as possible, the computer models will be calibrated so they reproduce floods that have occurred in the past. Therefore, it is necessary to gather information describing the height, extent and/or depth of floodwaters during past floods. The community is actively encouraged to contribute to the study by completing the online Questionnaire or sending information on past flooding experiences (including flood photos/videos). The community can also contact Council or Catchment Simulation Solutions (the consultant that will be completing the study) to discuss any aspect of the study.

The flood study is being completed as part of Council’s Floodplain Risk Management Program, which aims to reduce the impact of flooding on the community. It is funded by Council with additional funding and technical support provided by the NSW Government’s Office of Environment and Heritage. The study is being prepared by engineering consultancy, Catchment Simulation Solutions, who have completed many similar flood studies across NSW.
