More than 350 narrow boats are stuck in the ice at a Staffordshire marina.
The boats, moored at Barton Marina, near Burton-upon-Trent, have been stuck for days as temperatures have largely remained below freezing.
It means boats temporarily moored at the site have been unable to move, while permanent residents have faced problems such as frozen tap water.
Marina staff said the ice also brought safety concerns and that people should be careful.
About 100 people live on house boats at the site, while others take up long-term and short-term moorings.
Narrow boat owner Michael Lee said the piping system under the pontoon had frozen solid and people were having to carry buckets of water from the marina office.
Mr Lee said he was carrying six buckets a day back to his boat.
Caroline Kerr, of the Barton Marina management team, said walking on the iced-up jetties raised safety concerns.
"All the boats are iced up so people can slip getting on and off the boats," she added.
She said managers were making sure retired people living on the boats were keeping safe in the cold weather.
