Lough Derg, 13,000 acres, is the largest lake on the Shannon River (386 kms).
The lake extends approximately 40 kilometers from Portumna in the north to Killaloe in the south. The widest point is 12 kilometers between Scarriff and Youghal Bay.
Geograficly seen, the lake is divided in two parts each with its own characteristics.
The northern part with peninsulas and islands and the banks are sloping and fertile agricultural land interspersed with woods.
The southern part is landscaped a lot wilder and the lake much deeper, nearly 36 meters, because erosion has formed a deep gap between the mountains of Slieve Bernagh and Arra.
The southern section of the great Lough Derg around Killaloe and Ballina is a delight.
Great scenery and natural beauty combine with plenty of opportunities for boating and other water sports.
Lough Derg is a paradise for fishing enthusiasts who target on pike and coarse fish and as much attractive for people who wish to make a boat tour or enjoy the lake with a canoe.
