The Water Framework Directive (WFD) required Northern Ireland to define both surface and groundwaters as a coherent set of hydrological units. These units would then be monitored and managed to prevent deterioration in water quality and aquatic ecosystems through the implementation a programme of measures to drive improvements. This map displays Northern Ireland lakes which are greater than 50ha, which are assessed under WFD legislation and have been reported to EU from 2016.

Lakes defined under Article 2(5) of the Water Framework Directive. Only lakes of >50Ha or those that are part of the intercalibration process are included.

This dataset contains data collected for a variety of purposes through the activities of the CFB and the Regional Fisheries Boards. All information was collated by the CFB. The majority of records are from the Republic of Ireland with a small number of records from N. Ireland. More information on this dataset can be found in the Freshwater Metadatabase - BF_GBIF_7 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BF_GBIF_7).

The European Diatom Database (EDDI) is a web-based information system designed to enhance the application of diatom analysis to problems of surface water acidification, eutrophication and climate change.

This dataset includes 54 relatively small, shallow lakes from Northern Ireland. All sites are lowland, alkaline and cover a wide range of phosphorus concentrations. Surface sediment samples were collected during April 1990 and May 1991 and diatoms were counted by John Anderson. A regional diatom-total phosphorus transfer function was developed from these data and details are given in Anderson et al. (1993) and Anderson & Rippey (1994). These sites also form part of a larger training set used to develop a NW European diatom-total phosphorus inference model (Bennion et al., 1996). Palaeolimnological studies have been undertaken at a number of these sites (e.g. Anderson, 1989, 1997; Anderson & Rippey, 1994; Anderson et al., 1993; Rippey et al., 1997).

This feature class contains the polygon layer comprising the water bodies of the Public Angling Estate in Northern Ireland, and details all of the information for each fishery as set out in the Inland Fisheries 'Short Guide to Fisheries in the Public Angling Estate of Northern Ireland'. The polygons are derived from the February 2019 release of the 'Stand Water Polygon' and 'Water Course Polygon' layers from OSNI Fusion - a product from Ordnance Survey of Northern Ireland (OSNI). The layer is based on the coordinate system TM65 Irish Grid, and is linked to the 'PAE_OSNIFusion_Feb2019' table using a Relationship Class.

This table provides the raw data from river monitoring sites including Water Framework Directive monitoring sites. It should be noted that, as the data set is in its raw state, it cannot be used to provide a status without processing. The data set does not show Limits of Detection or Limit of Quantitation which would require a value to be treated as a half value for WFD calculation. In addition both altitude and alkalinity affect status calculations for some parameters. The data set may contain results which are erroneous due to typos, sampling error or contamination, such data points are usually several orders or magnitude above expected values.This is the first in a series of water data sets being made available as Open Data. Other data sets remain available on request via waterinfo@daera-ni.gov.ukThe European Water Framework Directive (2000/60/EC) has been transposed into Northern Ireland regulations through The Water Environment (Water Framework Directive) Regulations (Northern Ireland) 2017. The Water (Amendment) (Northern Ireland) (EU Exit) Regulations 2019 ensures that the Water Framework Directive (WFD) (as transposed) and the various supporting pieces of water legislation continue to operate here after 1 January 2021. The regulation encourage the active involvement of interested parties and the general public.The regulations set out the requirement to achieve 'Good Ecological Status' and 'Good Chemical Status' for all ground and surface waters (rivers, lakes, transitional waters, and coastal waters) within Northern Ireland.Surface waters are assessed according to the following criteria:Biological quality (fish, invertebrates, flora)HydromorphologicalPhysico-chemical properties like temperature, oxygenation and nutrient conditions.Chemical quality assessed against environmental quality standards for specific pollutants and priority substances.The following physio-chemical and chemical parameters are included in the data set:NO2-N(mg/l)- Nitrite

CSNIreOT1 begins in 1992 and ends in 2016, Moriarty et al (2017) detail the survey's history. The Celtic Sea Northern Irish Quarter 1 Otter Trawl Groundfish Survey Monitoring and Assessment Data resource contains both biological and sampling information. There are two sampling areas a "Full" data set, this includes rectangles that have a poor temporal sampling record. The "SSA" or "Standard Survey Area" sampling area only contains rectangles that have consistent temporal sampling and meet the criteria set out in Moriarty et al, (2017). The "sampling information" contains all the technical information required to describe each individual haul. The "biological information" contains all of the biological information required to describe the species length and weight distributions in each haul. Biological information is further classified by "baseline" data. This data contains a mix of species, genus, and family classifications, with a tag to say if it required further assessment and "null" length values, with a tag to say a length frequency distribution needs to be assigned. The "k-NN" or "k" number of nearest neighbours data has reconciled all of the taxonomic data to the highest resolution possible, and assigned an appropriate length distribution to the sample in question. Product type: * This product is the Standard Survey Area - Standard Monitoring Programme this is the recommended product for all analyses. * This product is the knn/resolved product which is recommended for all analyses.

For the 2nd cycle (2016-2021) 571 water bodies were identified in Northern Ireland, of these 496 are surface water bodies: including 450 rivers, 21 lakes, and 25 transitional and coastal waters (Marine); the remaining 75 are groundwater bodies.This layer displays the river waterbody boundaries based on surface water flow hydrological units. This is a 2016 2nd cycle revision of the earlier 2009 1st cycle hydrological unit split. Future revisions are not planned.

The European Diatom Database (EDDI) is a web-based information system designed to enhance the application of diatom analysis to problems of surface water acidification, eutrophication and climate change.

The Northwest European dataset is an amalgamation of six smaller regional datasets from southeast England, the English Midlands, Wales, Northern Ireland, Denmark, and Sweden. The lakes are mostly lowland, shallow, small, slightly acid to alkaline waters with agricultural activity and/or forestry in the catchments. The combined dataset spans a long TP gradient from oligotrophic to hypertrophic waters. Surface sediment samples (0-1 cm) were collected from the deepest point of each lake over the period 1990-1993 and diatoms were counted by either Helen Bennion (southeast England, meres, Wales), John Anderson (Northern Ireland, Denmark, Sweden) or Tim Allott (Wales). A program of taxonomic harmonisation was undertaken to construct a unified database of diatom data. The full dataset consists of 164 lakes but this was reduced to a training set of 152 lakes following data screening. This training set was used to develop a WAPLS diatom-TP transfer function and component 2 gave the lowest prediction error (RMSEP=0.21 log10TP �g l-1, apparent r2=0.91). Further details of the training set and transfer function are given in Bennion et al., 1996) and the model has subsequently been applied to numerous diatom sequences to reconstruct lake nutrient histories (e.g. Bennion et al., 1996, 1999, 2000, 2001).
