With an area of 151 square miles (392 km2), it is the British Isles' largest lake, the 15th largest freshwater lake within the European Union and is ranked 31st in the list of largest lakes of Europe. Located 20 miles (32 km) west of Belfast, it is about 20 miles (32 km) long and 9 miles (14 km) wide. It is very shallow around the margins and the average depth in the main body of the lake is about 30 feet (9 m), although at its deepest the lough is about 80 feet (24 m) deep.
Geologically the Lough Neagh Basin is a depression, built from many tectonic events dating back as far as 400 million years ago. These tectonic events are responsible for a NE-SW bedrock structure which has controlled many subsequent events. During the Paleozolic era, the Lough Neagh Basin was a depositional graben.
Of the 1,760-square-mile (4,550 km2) catchment area, around 9% lies in the Republic of Ireland and 91% in Northern Ireland; 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 as part of the Bann. Lough Neagh is fed by many tributaries including the rivers Main (34 mi, 55 km), Six Mile Water (21 mi, 34 km), Upper Bann (40 mi, 64 km), Blackwater (57 mi, 92 km), Ballinderry (29 mi, 47 km) and Moyola (31 mi, 50 km)

Although the Lough is used for a variety of recreational and commercial activities, it is exposed and tends to get extremely rough very quickly in windy conditions.
The lough is used by Northern Ireland Water as a source of fresh water. The lough supplies 40% of the region's drinking water. There have long been plans to increase the amount of water drawn from the lough, through a new water treatment works at Hog Park Point, but these are yet to materialise.
The lough's ownership by the Earl of Shaftesbury has implications for planned changes to state-run domestic water services in Northern Ireland, as the lough is also used as a sewage outfall, and this arrangement is only permissible through British Crown immunity. In 2012, it was reported that the Earl is considering transferring ownership of the Lough to the Northern Ireland Assembly.
Traditional working boats on Lough Neagh include wide-beamed 4.9-to-6.4-metre (16 to 21 ft) clinker-built, sprit-rigged working boats and smaller flat-bottomed "cots" and "flats". Barges, here called "lighters", were used until the 1940s to transport coal over the lough and adjacent canals. Until the 17th century, log boats (coití) were the main means of transport. Few traditional boats are left now, but a community-based group on the southern shore of the lough is rebuilding a series of working boats.
In the 19th century, three canals were constructed, using the lough to link various ports and cities: the Lagan Navigation provided a link from the city of Belfast, the Newry Canal linked to the port of Newry, and the Ulster Canal led to the Lough Erne navigations, providing a navigable inland route via the River Shannon to Limerick, Dublin and Waterford. The Lower Bann was also navigable to Coleraine and the Antrim coast, and the short Coalisland Canal provided a route for coal transportation. Of these waterways, only the Lower Bann remains open today, although a restoration plan for the Ulster Canal is currently in progress.
Lough Neagh Rescue provides a search and rescue service 24 hours a day and has 3 stations, situated around the lough. These are at Antrim Ardboe and Kinnego Marinas, Kinnego being its headquarters and founding station. It is a voluntary service funded by the district councils bordering the Lough. Its members are highly trained and are a declared facility for the Maritime and Coastguard Agency which co-ordinates rescues on Lough Neagh.
The flora of the north-east of Northern Ireland includes the algae: Chara aspera, Chara globularis var. globularis, Chara globularis var. virgate, Chara vulgaris var. vulgaris, Chara vulgaris var. papillata, Tolypella nidifica var. glomerata.

Violoa tricolor ssp. curtissi, Hypericum androsaemum, Hypericum maculatum, Elatine hydropiper, Silene vulgaris, Silene dioica, Saponaria officinalis, Cerastium arvense, Cerastium semidecandrum, Cerastium diffusum, Sagina nodosa, Spergularia rubra, Spergulaia rupicola, Chenopodium bonus-henricus, Chenopodium polyspermum. 
Eel fishing has been a major industry in Lough Neagh for centuries. These European eels make their way from the Sargasso Sea in the Atlantic Ocean, some 4,000 miles (6,000 km) along the Gulf Stream to the mouth of the River Bann, and then make their way into the lough. They remain there for some 10 to 15 years, maturing, before returning to the Sargasso to spawn. Today Lough Neagh eel fisheries export their eels to restaurants all over the world, and the Lough Neagh Eel has been granted Protected Geographical Status under European Union law.
The lough's English name derives from the Irish from Irish: Loch nEachach, meaning "Eachaidh's lake". In the aftermath of the Plantation of Ulster, the names Lough Sydney and Lough Chichester were variously applied, in honour of the Lord Deputies of the same name, however, they did not supplant "the more ancient though less refined appellation".
Mythology and folkloreEdit
In the Irish mythical tale Cath Maige Tuired ("the Battle of Moytura"), Lough Neagh is called one of the 12 chief loughs of Ireland. The origin of the lake and its name is explained in an Irish tale that was written down in the Middle Ages, but is likely pre-Christian. According to the tale, the lake is named after Echaid (modern spelling: Eochaidh or Eachaidh), who was the son of Mairid (Mairidh), a king of Munster. Echaid falls in love with his stepmother, a young woman named Ébliu (Ébhlinne). They try to elope, accompanied by many of their retainers, but someone kills their horses. In some versions, the horses are killed by Midir (Midhir), which may be another name for Ébliu's husband Mairid. Óengus (Aonghus) then appears and gives them an enormous horse that can carry all their belongings. Óengus warns that they must not let the horse rest or it will be their doom. However, after reaching Ulster the horse stops and urinates, and a spring rises from the spot. Echaid decides to build a house there and covers the spring with a capstone to stop it overflowing. One night, the capstone is not replaced and the spring overflows, drowning Echaid and most of his family, and creating Loch n-Echach (Loch nEachach: the lake of Eochaidh or Eachaidh).
The character Eochaidh refers to The Daghdha, a god of the ancient Irish who was also known as Eochaidh Ollathair (meaning "horseman, father of all"). Ébhlinne, Midhir and Aonghus were also names of deities. Dáithí Ó hÓgáin writes that the idea of a supernatural being creating the landscape with its own body is an ancient one common to many pre-Christian cultures. A Gaelic sept called the Uí Eachach (meaning "descendents of Eochaidh") dwelt in the area and it is likely that their name comes from the cult of the god Eochaidh.
Another tale tells how the lake was formed when Ireland's legendary giant Fionn mac Cumhaill (Finn McCool) scooped up a chunk of earth and tossed it at a Scottish rival. It fell into the Irish Sea, forming the Isle of Man, while the crater left behind filled with water to form Lough Neagh.
Sir Hugh Clotworthy settled from England near Antrim town in the reign of Elizabeth I and was granted the office of "Captain of Lough Neagh", with a stipend in return for maintaining boats on the lake to enforce royal authority. Clotworthy's successors as captain were his son and grandson-in-law, the first and second Viscounts Massereene. In 1660 Charles II gave the first Viscount the rights to the fish and bed of the lake.
