Water Management publishes a growing number of water-related datasets on the Open Data NI website. Data are downloadable and available in a variety of formats.
Some layers displayed on the mapper are available on the WMU Spatial Datasets page, which can be downloaded and used within your own project. Follow the guidance on the web page.
A full description of WFD classification for freshwaters, including chemical standards and with references to supporting documents, can be found on the UK TAG Water Framework Directive site.
The River Basin Management page gives details of WFD progression in Northern Ireland.
The Environmental Change Network includes sites for Northern Ireland, and long term data sets can be accessed via their website.
If you require any additional freshwater, groundwater or marine-related data, contact us using our Water Info Requests mailbox.
