The Gearagh valley is located 3 km south of Macroom, County Cork, and forms part of the channel of the Lee river. In the 1950s the valley was dammed, trees felled and 60% of it flooded for a hydroelectric scheme. Some of the original alluvial woodland remains. The site also encompasses the upper part of the Iniscarra reservoir as far as the Carrigadrohid Dam.
The site was designated as a Special Protection Area on the basis of its migratory waterfowl, notably those species wintering in numbers of national importance: Anas penelope (2,000 birds, 1996), Anas crecca (1,600 birds, 1996), Anas platyrhynchos (1,750 birds, 1985), Fulica atra (312 birds, 1995) and Pluvialis apricaria (1,500 birds, 1985).
