The Office of Public Works (OPW) is responsible for the maintenance of Arterial Drainage Schemes and catchment drainage schemes designated under the Arterial Drainage Acts of 1945 and 1995. The Gweestin River does not form part of an Arterial Drainage Scheme. Therefore, the OPW has no responsibilities for the maintenance of this channel. Local flooding issues are a matter, in the first instance, for each Local Authority to investigate and address. All Local Authorities may carry out flood mitigation works, using either their own resources, or by applying for funding under the OPW Minor Flood Mitigation Works and Coastal Protection Scheme, the details of which are available at www.gov.ie/en/publication/0e3b3d-minor-flood-mitigation-works-and-coastal-protection-scheme/
