‘Tons of rubbish and debris have piled up in a dock turning the water into a blanket of litter.
The lock on Preston Docks is choked with at least 50m of litter which has travelled down the River Ribble.
The water is choked with plastic bottles, driftwood and even car tyres as far as the eye can see.
It is understood the debris was blown into the holding area in Preston, Lancashire, by strong winds overnight.
Photographer Donna Clifford, 38, spotted the debris on Thursday.
She said: ‘It was really windy so I thought I would go down and photograph waves in the dock.’
