Lough Neagh is a large freshwater lake in Northern Ireland, and the largest in the island of Ireland, the United Kingdom and the British Isles overall, with a surface area of 151 square miles. It supplies 40% of Northern Ireland's water. Its main inflows are the Upper River Bann and River Blackwater, and its main outflow is the Lower River Bann. Its name comes from Irish Loch nEachach[ˌl̪ˠɔx ˈn̠ʲahəx], meaning "Eachaidh's lake". The lough is owned by the Earl of Shaftesbury and managed by Lough Neagh Partnership Ltd.
Lough Erne is the name of two connected lakes in County Fermanagh, Northern Ireland. It is the second-biggest lake system in Northern Ireland and Ulster, and the fourth biggest in Ireland. The lakes are widened sections of the River Erne, which flows north and then curves west into the Atlantic. The smaller southern lake is called the Upper Lough as it is higher up the river. The bigger northern lake is called the Lower Lough or Broad Lough. The town of Enniskillen lies on the short stretch of river between the lakes. The lake has more than 150 islands, along with many coves and inlets. The River Erne is 80 miles (129 km) long and drains an area of about 1680 square miles (4,350 km2).
Loch Morar is a freshwater loch in Lochaber, Highland, Scotland. It is the fifth-largest loch by surface area in Scotland, at 26.7 km2 (10.3 sq mi), and the deepest freshwater body in the British Isles with a maximum depth of 310 m (1,017 ft). The loch was created by glacial action around 10,000 years ago, and has a surface elevation of 9 metres (30 ft) above sea level. It separates the traditional district of North Morar, from Arisaig and Moidart.
A lake-burst is a phenomenon referred to in Irish mythology, in which a previously non-existent lake comes into being, often when a grave is being dug. Part of the lake-burst stories may originate in sudden hydrographic changes around limestone-based inland plains or turloughs. Other so-called lake-bursts refer to marine estuaries, bays and inlets, such as Galway Bay, Strangford Lough, Dundrum Bay, Belfast Lough, Waterford Harbour and the mouth of the River Erne. Some of these coastal districts were renowned for the drowned prehistoric forests, which gave rise to several flood-myths.

Loch Ness is a large freshwater loch in the Scottish Highlands extending for approximately 37 kilometres southwest of Inverness. It takes its name from the River Ness, which flows from the northern end. Loch Ness is best known for alleged sightings of the cryptozoological Loch Ness Monster, also known affectionately as "Nessie". It is one of a series of interconnected, murky bodies of water in Scotland; its water visibility is exceptionally low due to a high peat content in the surrounding soil. The southern end connects to Loch Oich by the River Oich and a section of the Caledonian Canal. The northern end connects to Loch Dochfour via the River Ness, which then ultimately leads to the North Sea via the Moray Firth.
Loch Langavat is the name of several freshwater lochs in the Outer Hebrides of Scotland. The name is a Gaelic rendition of Old Norse lang "long" and vatn, meaning "lake".

Loch Màma is a small freshwater loch in South Morar, Lochaber, in the north west of Scotland. It forms a simple basin and is orientated east to west. It is thought that the adjoining loch Loch na Creige Duibhe and Loch Màma were at one time a single loch. Debris brought down by the Allt Dearg stream has likely caused the lochs to be separated into two bodies of water. The loch is the source of the river Allt a' Mhama.
