A shallow coastal lagoon, separated from the sea by a barrier of sand and shingle, and situated 3 km west of Carnsore Point in County Wexford. The lake has three islands, Lady's Island (now connected to the mainland by a causeway and included within the IBA), Inish and Sgarbheen.
This is an internationally important site for breeding terns, with colonies of four species (formerly five) present. The site was formerly of international importance for wintering waterfowl and still holds nationally important numbers of Aythya ferina (639 birds, 1995), Aythya marila (140 birds, 1996), Anas penelope (1,850 birds, 1996), Anas crecca (72 birds, 1996), Aythya fuligula (231 birds, 1995) and Vanellus vanellus (2,230 birds, 1995).
