Afon Wygyr Water Quality and Habitat Improvement Project Final Report January 2020

Feb 19, 2020

This report summarises the work carried out on the Afon Wygyr catchment on Anglesey to improve water quality and habitat. In 2017 the Clwyd, Conwy and Gwynedd Rivers Trust surveyed the habitat along the 10 largest rivers on Anglesey in the Anglesey Rivers Project funded by Anglesey Council’s AONB Sustainable Development Fund (SDF).

This survey identified that the River Wygyr, which enters the sea at Cemaes, was affected in some areas by trampling of the river banks by cattle using the river for drinking, causing large quantities of silt and organic matter to enter the river. This was affecting bankside and instream habitats for fish and other wildlife. In addition, investigations by Natural Resources Wales (NRW) into the reasons for the poor quality of the bathing water at Cemaes showed that bacteria from agricultural sources in the river was contributing to the poor quality of the bathing water in 2017. In 2018 the Trust was successful in obtaining funding from Anglesey County Council’s AONB SDF, NRW and Horizon Nuclear for a project to improve both the habitat and water quality on the River Wygyr.
