I am advised that matters relating to cleaning or maintenance of a river or stream is an issue for the relevant Local Authority. In that context, it would be the norm that the Local Authority would engage in consultation with, among others, Inland Fisheries Ireland (IFI) which is the statutory body charged with ensuring the protection and conservation of our fisheries resource and habitats.
The organisation of works is a matter for the Local Authority and IFI assists Local Authorities in ensuring any proposed works would comply with relevant fisheries legislation.
