Statement

In 2002-2003 polygon geometry from a cartographic source (Ordnance Survey Ireland vector Discovery Series water lines) was attributed with a unique code for each lake polygon and a lake name where a name was visible at 1:50,000. Some local names were also applied from the EPA monitoring program stations list. This Lake Segments layer was used as the base geometry for the Lake Waterbodies polygons. A "System B" typology was found to be the most appropriate basis on which to define lake types in Ireland; twelve types have been identified using the factors alkalinity (surrogate for Geology), depth and size.

Biological data from 60 high status lakes across several types and River Basin Districts were used to test that the selected hydromorphological types, derived from these factors, can be discriminated on a biological basis. A thirteenth type was identified to include a number of lakes at altitude >300m. Latitude and longitude were not considered to be significant factors determining the flora and fauna of Irish lakes.

The typology and risk assessment of Irish lakes for Article 5 included all lakes greater than 0.5 km² and lakes less than 0.5 km² if they were located in protected areas (e.g. in Special Areas of Conservation, or if they were used for water abstraction for drinking purposes). Spatial Accuracy: data mapped from a 1:50,000 scale source.

Spatial Accuracy: data mapped from a 1:50,000 scale source. Thematic Accuracy: Lake Waterbody attributes are based on type criteria originating from the WFD System B typology. Altitude data came from a 20m resolution DTM. Alkalinity categories came from Geological Survey Ireland source data. Currency: Geometry from the 1:50,000 OS Discovery Series, published in 1998 Logical Consistency: The dataset meets the topological requirements set out in Guidance Document No. 22: Support for Reporting of RBMP, Guidance on reporting of spatial data.
