A large freshwater lake adjacent to Donegal Bay and situated 10 km north of Ballyshannon in County Donegal. The lake is separated from the sea by sand-dunes, is fringed by extensive reedbeds and large areas of wet grassland, and is surrounded by drumlins.
This is an important wintering site for waterfowl, particularly swans Cygnus. Formerly, Aythya marila was also recorded in internationally important numbers. The fields around Durnesh Lough are an alternative feeding site for Anser albifrons flavirostris from Pettigo plateau (site 027).
