Lough Derravaragh is located approximately 12 km north of Mullingar town, in County Westmeath. The River Inny flows into and out of the north-west end of the lake, which is wide and shallow with extensive reedbed and swamp, backed by small areas of raised bog. The south-east arm of the lake is long and narrow, with freshwater marsh and fen. The lake is important for fishing and is used for water-sports.
The same flock of Anser albifrons flavirostris also uses sites 135, 136, 139 and 140. Other species which occur in numbers of national importance are Tachybaptus ruficollis (34 birds, 1996), Cygnus olor (128 birds, 1996), Aythya fuligula (1,800 birds, 1996) and Fulica atra (643 birds, 1996).
