Situated on the Dunkellin river, west of Craughwell in south-west Galway, this is the last large turlough (karst lake) remaining in Ireland. The site comprises marshes, seasonally flooded wet meadows, with limestone outcrops and scrub at its margins. In the summer the site is grazed by cattle and sheep.
This is an important site for wintering waterfowl. Species wintering in nationally important numbers include Anser albifrons flavirostris (139 birds, 1995) and Anas penelope (5,570 birds, 1996).
Pressure/threats to key biodiversity
Drainage of the site has been a long-standing threat. However, its designation as a Special Protection Area and its status as a proposed candidate Special Area for Conservation (Rahasane Turlough; area not known) should reduce this threat. Disturbance to wintering birds is caused by wildfowling. There has been some clearance of limestone pavement next to the lake, with implications for water quality and disturbance to birds.
