The list of Lakes and lochs of the United Kingdom is a link page for the lakes of the United Kingdom (England, Scotland, Wales and Northern Ireland), including lochs fully enclosed by land.
Lakes in Scotland are called lochs, in Northern Ireland it is spelt loughs but said the same way, and in Wales a lake is a Llyn . Note that the words, loch and lough, in addition to referring to bodies of freshwater (lakes), are also applied to bodies of brackish water or seawater, which in other countries or contexts may be called fjord, firth, strait, estuary, bay etc.
These lists are made more complicated by the fact that many of the largest lakes in England and Wales are man-made reservoirs, or lakes whose size has been increased by damming.
This table includes the ten largest fresh water bodies by area. Lough Neagh is the largest water body in the UK by this measure, although Loch Ness is the largest by volume and contains nearly double the amount of water in all the lakes of England and Wales combined. Loch Morar is the deepest of the UK's lakes and Loch Awe the longest. Murray and Pullar (1910) note that the mean depth of Loch Ness is 57.4% of the maximum depth - higher than in any other large deep loch in Scotland. The deepest lake in England is Wastwater which descends to 76 metres (249 ft).
