Sydney Water’s expert leak detection dogs Winnie and Ziggy recently inspected Lake Parramatta for sewer leaks using their powerful sense of smell. Much like sniffer dogs at airports, Winnie and Ziggy signal a find by lying down. No leaks were found in the designated swimming area, helping to ensure the water remains safe for visitors.

After their work, the dogs were rewarded with a well-earned play with their favourite ball.

Reminder: Only swim in the supervised area when lifeguards are on duty (October to April) and never swim alone. The 2025/26 swim season starts in late October.
