Two children had to be assessed after an incident in a stormwater drain in Canberra's south following more than 24-hours of record-breaking rain.
Emergency services received a triple-0 call about 3.30pm alerting them to a boy caught in a drain going under Ashley Drive in Richardson.
Firefighters set up downstream recovery lines in preparation for a rescue, but the boy managed to free himself from the water before they were needed.
Paramedics assessed two boys at the scene, including the one who had been in the water, but found no serious injuries.
The incident comes after about 90 millimetres of rain fell in the Tuggeranong Valley between Monday afternoon and Tuesday evening, which broke Canberra's September records for 24-hour rainfall.
Emergency services urged the community to stay clear of drains and fast-moving waterways, which could be extra dangerous after heavy rainfall.
