Environment Agency Wales, (
Asiantaeth yr Amgylchedd Cymru in
Welsh) was, until 31 March 2013, a
Welsh Government Sponsored Body, while also being part of the
Environment Agency for England and Wales. It had an operational area defined along its Eastern boundary by the catchments of the
River Dee and the
River Wye. Those parts of the
River Severn in Wales are managed by the Environment Agency whilst those parts of the River Dee and River Wye catchments that are in England are nevertheless managed by Environment Agency Wales. The Agency also had a public facing boundary which corresponded to the political boundary of Wales. Its principal aims were to protect and improve the environment in
Wales and to promote
sustainable development.
