A group of artists are raising awareness of the "catastrophic problem" of pollution in the River Wye with an exhibition.
Campaigners from the Save the Wye group have created a display of 16 glass panels which trace the journey of the river and the build-up of pollution as it flows towards the sea.
It is on display at the Forest of Dean District Council offices in Coleford, Gloucestershire until 30 June.
"The new exhibition looks incredible and really helps to spread the message about the deterioration of our waterways in the Forest of Dean," said the council's river water quality champion Andrew McDermid.
