This auxiliary spillway was completed in 2002 beside Warragamba Dam to protect against extreme flood events. The massive civil engineering project ensures that excess floodwaters can bypass the main dam wall, preventing overtopping. It stands as a safeguard for Sydney’s water security, complementing the dam’s original controlled spillways.
