Site description
Carrowmore lake is situated 2.5 km north-west of Bangor, in north-west County Mayo. It is a medium-sized, fairly shallow lake, originally with low to moderate nutrient-levels (oligotrophic-mesotrophic), and is surrounded by blanket bog and some new forestry plantations. The IBA is considerably larger than in the previous European inventory (Grimmett and Jones 1989), when it comprised solely Darreen's Island, a low-lying grassy island in the north-western part of the lake. The lake is used for angling.

Key biodiversity
At Darreen's Island, in Carrowmore lake, there is a long-established colony of gulls Larus. Formerly the site was also important for breeding terns Sterna, particularly Sterna sandvicensis (164 pairs, 1984) and Sterna paradisaea (18 pairs, 1984). However, in recent years neither of these species, nor Larus ridibundus (1,500 pairs, 1987), have bred here. It is believed that the terns switched to Inishderry Island in Broadhaven Bay (site 041) and that they may interchange between the two sites. Anser albifrons flavirostris winters in numbers of national importance (146, 1994); this flock also uses sites 046 and 041.
