Lough Neagh and Green Irish Terrain
Lough Neagh is a freshwater lake in Northern Ireland (upper right quadrant). With an area of 392 square kilometres (151 square miles), it is the largest lake in the British Isles and ranks among the forty largest lakes of Europe.
Located twenty miles (30 km) to the west of Belfast, it is approximately twenty miles (30 km) long and nine miles (15 km) wide with an area of 392 square kilometres (151 square miles).
It is very shallow around the margins and the average depth in the main body of the lake is about 9 m (30 ft); although at its deepest the lough is about 25 metres (80 ft) deep.
Of the 4550 km² catchment area, around 9% lies in the Republic of Ireland and 91% in Northern Ireland. The bright green terrain of Northern Ireland and the northern part of the Republic of Ireland can be seen in this relatively cloud-free image.
Altogether 43% of the land area of Northern Ireland is drained into the lough, which itself flows out northwards to the sea via the River Bann. As one of its sources is the Upper Bann, the Lough can itself be considered a part of the Bann.
