A woman who broke her spine falling 30 feet down a steep embankment into a river was homeless and known to a Stockport charity that helps rough sleepers.
The 32-year-old was living in a network of caves near the town centre, where homeless people frequently seek shelter, with her partner.
Charity workers have warned of how dangerous the area is and called for better provision for rough sleepers so they would not put themselves at risk by staying there.
The women fell down an embankment near Stockport Pyramid, used to access the caves, shortly after 7pm on Friday.
She is understood to have fractured her spine in two places and is still being treated in Wythenshawe Hospital.
Five fire engines, a water incident unit, two police cars, a tactical response unit and two ambulances all attended the scene off Brinksway.
It took more than three hours before specialist water rescue firefighters managed to recover her on a dinghy.
The hidden caves perched on a 20 foot precipice overhanging the River Mersey have become a home for many without shelter in the past few years.
Speaking to the Manchester Evening News earlier this year Jonathan Billings from the Wellspring homeless charity warned someone would soon be seriously hurt using the caves as a home.
