WFD Open Data

This is the Water Framework Directive (WFD) Open Data API which has seven API datasets: Catchment, Subcatchment, Waterbody, WaterbodyTrend, MonitoringProgramme, Dashboard and Search. This information is populated using the EPA’s CRM system, WFD Application and GIS Vector database. The Catchment Science Management Unit and the Aquatics team in the EPA manage this data via CRM and the WFD Application. The EPA provides this information to the public via the responsive catchments.ie website.
