Floodplain Risk Management Study

Narrandera Floodplain Risk Management Study

There is a long history of flooding from the Murrumbidgee River in Narrandera. Serious flooding has been reported since settlement began over 150 years ago. Formal gauging of river levels in Narrandera commenced in 1892, with gauging upstream in Gundagai and Wagga Wagga, and downstream at Hay and Balranald prior to this in 1887. The objectives of the FRMS are:

  • Review the Narrandera Flood Study
  • Determine flood damages in the study area for the full range of flood events
  • Identify and compare various risk management options to deal with existing flood risk in the Gillenbah area, considering and assessing their social, economic, ecological and cultural impacts and examination of ways to mitigate impacts
  • Examine types of future development that may be compatible with the level of flood risk in the study area to assist Council in future planning decisions
  • Develop appropriate development controls for flood risk compatible development and future redevelopment of existing development in the floodplain
  • Assess the cumulative impact of any potential new development given the proposed development controls and potential extent of development
  • Assess the impacts of potential future changes to major infrastructure
  • Define the potential for overtopping of the Main Canal in extreme flood events
  • Examine appropriate management measures to deal with the danger to personal safety and damages from continuing risk associated with an extreme flood event
  • Integration of flood information into Council’s GIS system as an overlay
  • Identify current gaps in Council’s Flood Prone Land Policy
  • Provide recommendations for floodplain risk management in Narrandera which will form the basis of the Narrandera Floodplain Risk Management Plan (separate report).
