Ecological statuses of all lake waterbodies across Northern Ireland for the 2016-2021 Waterframework Directive cycle. Lake outlines available from OpenDataNI under the UK Open Government Licence. 2021 statuses provided by the DAERA NIEA Water Management Unit on 21/12/2023.

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.

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 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).

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.

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).

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.

The Eel Monitoring Programme (EMP) at Inland Fisheries Ireland uses fyke net surveys to assess yellow eel populations in lakes, main channel rivers, canals, transitional waters and lagoons. For further information on the methodology used in the surveys please contact IFI, methodology includes the use of chains of 5 nets, along with repeating historical surveys with chains of 10 nets. This dataset contains data including year of sampling, waterbody name and type, catchment name and river basin district (RBD). The Erne catchment is monitored as part of the North West International River Basin District (NWIRBD) as an eel management unit under Irelands Eel Management Plan in collaboration with agencies in Northern Ireland.Catch data on yellow eels for surveys are presented, including, numbers of eels captured/measured and summarised length and weight results for summer fyke netting European Eel surveys (yellow eel life stage) along with length frequency breakdowns of catches. Net*Nights are calculated by multiplying the number of nets set by the number of night that the nets were allowed to fish.
