A man is being treated in hospital for hypothermia after he was pulled from the River Great Ouse in Bedford.
Specialist trained water rescue officers from the Bedfordshire Fire and Rescue Service went into the water near Goldington Road in Bedford to save the man.
He was clinging to twigs to avoid being swept away by the current. He was then taken to hospital suffering from shock and hypothermia.
Assistant Chief Fire Officer Dave Fothergill said. "Even for fully trained and equipped Firefighters, rescues such as this are particularly hazardous. This was a courageous action by our team in extremely dangerous conditions.
Rivers and watercourses present significant hazards at all times, but are extremely dangerous when in full flood like this. People should never go near water courses in flood conditions and should stay well clear, whether on foot or in vehicles."
