A final design for raising the Warragamba Dam wall by around 14 metres is required to significantly reduce and mitigate flood risk by 2020. Raising the Warragamba Dam wall by around 14 metres was found to be a cost effective measure for reducing flood damages and risk to life. It will result in a 75% reduction on average annually in the damage expected from floods and significantly reduce the risk to life from flood events. Proceeding to construction is subject to environmental and planning approvals. INSW was consulted for the information included for this project.
