Lakes


The largest lake is Lough Neagh in the north-east. 29km in length and some 18km in width, it covers a total area of 381 sq.km. Other large lakes are Lough Corrib (Co. Galway, 175 sq.km), Lower Lough Erne (Co. Fermanagh, 112 sq.km) and, on the Shannon, Loughs Derg and Ree (118 and 105 sq. km respectively).

Other important lakes include Loughs Mask and Conn, Co. Mayo, Lough Allen in the Upper Shannon, Lough Macnean in Co. Leitrim, Loughs Owel, Ennel and Derravaragh in Co. Westmeath, and the famous Lakes of Killarney in Co. Kerry. Several thousand small lakes are widely distributed, particularly in the west and in parts of the north.

These lakes are all natural creations, the result of various processes such as subsidence (Lough Neagh), limestone solution (e.g. Lough Ree) and landform change during and after the last Ice Age. In addition, there are various man-made lakes which have been constructed as reservoirs (e.g. at Roundwood, Co. Wicklow and at Silent Valley in the Mourne Mountains), or as a result of damming rivers for hydro-electric power (as at Poulaphouca, Co. Wicklow, Cathleen's Falls, near Ballyshannon, Co. Donegal, and Iniscarra, Co. Cork).

The largest man-made lake is at Poulaphouca (1200 hectares as the area of Poulaphouca Reservoir), which now has a multi-use function as a reservoir for Dublin city and as a major recreational resource.

Lower Lough Erne

The drive along route A47 crosses Boa Island between Kesh and Leggs. At the right time of day the view can be breathtaking.
