The emergency services have assisted a woman from the River Wensum in Norwich.
The woman went into the river near to the Premier Inn, with police, fire crews and the ambulance service called at 12.45pm.
Lucy Burchnall, head ranger at the Broads Authority said Rob Ford, a quay assistant from the nearby yacht station had also been on the scene.
She said: 'Rob saw a person in the water and got on the dory and went to assist. He met police and fire service personnel on the scene and helped them rescue the lady.
'Rob also notified Broads control so we also responded and shut down the river on either side. The woman must have been in the water for more than an hour before she was pulled out by emergency services.
'Lucky for her the water is quite warm at this time of the year.'
After being taken from the water, the woman was led away by emergency services personnel.
