Lough Derg, historically Lough Dergart (Irish: Loch Deirgeirt),[1] is a freshwater lake in the Shannon River Basin, Ireland. It is the second-biggest lake in the Republic of Ireland and the third-biggest on the island of Ireland (after Lough Neagh and Lough Corrib).
It is a long, narrow lake, with shores in counties Clare (south-west), Galway (north-west), and Tipperary (to the east). It is the southernmost of three large lakes on the River Shannon; the others being Lough Ree and Lough Allen. Towns and villages on Lough Derg include Portumna, Killaloe & Ballina, Dromineer, Terryglass, Mountshannon and Garrykennedy.
The lake's name evolved from the Irish Loch Deirgdheirc.[1] This was one of the names of The Dagda, an Irish god, and literally means "red eye".[2]
Geography
At its deepest, the lake is 36 metres[3] deep and covers an area of 130 km² (50.2 sq miles). Close downstream from where Lough Derg empties into the Shannon are the falls of Doonass, the largest fall on the otherwise gently sloping river. Nearby is the location of the hydroelectric power plant at Ardnacrusha, which, when built in 1927 was the world's largest.
Usage
In the nineteenth century, Lough Derg was an important artery from the port at Limerick to Dublin through the canals in the midlands of Ireland. Navigable over its full 40 km length, Lough Derg is today popular with cruisers and other pleasure traffic, as well as sailing and fishing. The University of Limerick have an activity centre by the lake, just north of Killaloe, where there are canoes, kayaks, windsurfing, sailing dingies, and other recreations.
In June 2013, 35 people were brought to safety when a major rescue effort was undertaken after an international rowing event was hit by severe weather.[4]
Ecology
A breeding pair of white-tailed eagles first nested on an island in Lough Derg in 2012. This marked a great success for the Irish reintroduction programme started in the summer of 2007.[5][6][7]
The North-East Shore is listed as a Special Area of Conservation.[8]
