Statement

For the purposes of hydrological activities and by agreement between the various hydrological agencies in Northern Ireland and the Republic of Ireland, Ireland was divided into 40 hydrometric areas. Each Hydrometric Area comprises a single large river basin, or a group of smaller ones, and neighbouring coastal areas. Each area was assigned a number from 01 to 40 beginning at the Foyle Catchment and proceeding in a clockwise direction (an exception to this general scheme is the catchment of the River Shannon and its tributaries which, because of its size, was divided into two hydrometric areas, 25 (Lower Shannon) and 26 (Upper Shannon)). The boundaries recorded in the hydrometric areas map were originally based on the hydrologic divisions shown on the 1958 Ordnance Survey Ireland (OSi) map - Rivers and their catchment basins. Digitisation was carried out in 1997 from the 1958 source (1:63,360). Attributes are the hydrometric area number (assigned by EPA) and area calculated from the polygons themselves and associated (I)RBD. Shared boundaries between hydrometric areas and (I)RBDs have been updated as a result of field verification processes. Hydrological errors still exist in HA boundaries not shared with (I)RBDs.
