Loch vs Lake

Lochs and lakes are both large inland bodies of water. So what is the difference between a loch and a lake? Well, the main distinction is where they are located. Lochs can be found in Scotland and Ireland whilst lakes are found elsewhere in the world. This is because the word ‘loch’ comes from the Gaelic languages which were historically used in these parts of Britain.

Another key difference between lochs and lakes is that ‘loch’ can refer to various types of water formations. For example, a loch can refer to:

  • A natural lake

  • An artificial lake

  • A sea inlet

  • A firth

In contrast, a lake is usually understood to be landlocked and not have access to the sea or ocean. In Scotland, you may hear these large ocean inlets referred to as sea lochs.

Why Do Scots Call Lakes Lochs?

Scots call lakes lochs because it’s been passed down in their language. The word ‘loch’ is believed to have been brought to Scotland by the Gaels. Gaels were a Celtic tribe who settled in Scotland, Ireland, and the Isle of Man. ‘Loch’ was used to describe the many lakes and inlets that are found in the Scottish and Irish landscapes. Nowadays, the word loch is still used, tying Scottish people to their heritage.

Are There Any Lakes in Scotland?

Yes, there is one official lake in Scotland. It’s called the Lake of Menteith and is located near Stirling in central Scotland. We’re not completely sure why the Lake of Menteith is called a lake and not a loch. However, it’s thought to be something to do with English influence. Until the 19th century, there are records of Menteith being called a loch. However, one theory is that in 1838 when the UK Government’s Ordnance Survey mapped the area they named it a lake instead and this became cemented.

In the Lake of Menteith, you can find the Island of Inchmahome which has had many famous guests throughout history. Mary Queen of Scots used it as a refuge when she was an infant and Scottish hero Robert the Bruce is reported to have visited three times in 1305, 1308 and 1310.

Lochs vs Fjords

Lochs and fjords are also both bodies of water, but they have a few distinct characteristics. Again, lochs are tied to the Gaelic language, meaning you can find them in Scotland and Ireland; whereas fjords are typical for Norway, Greenland, Canada, Chile, and New Zealand. Whilst lochs come in many different shapes and sizes, fjords are formed by a specific geological process. They exist where glacial erosion has created a deep, steep-sided valley between cliffs. These valleys are then flooded by water from the sea to create fjords.

Lochs in Scottish Culture

Lochs play a significant role in Scottish culture. They’ve historically been involved in many epic Scottish battles. For example the Battle of the Shirts was a brutal clan fight that took place on the banks of Loch Lochy in 1544 between Clan Macdonald and Clans Fraser and Grant.

Lochs have also been an important source of food for the Scottish people. Fish such as salmon and trout have been caught in the lochs for centuries. Now, fishing on the Scottish lochs is not only an important export, but it’s also a popular hobby. Many people flock to Scotland’s Highlands to make the most of the fishing opportunities and to admire some spectacular views whilst they are at it.

Scottish folklore, art, and literature have also been heavily influenced by Scotland’s mesmerising lochs. Legends of the great Loch Ness monster who dwells in Loch Ness are known the world over. The beautiful Loch Lomond inspired the popular Scottish song The Bonnie Banks of Loch Lomond. It’s not surprising that Scotland’s national poet Robert Burns was also inspired by the lochs. His poem On Scaring Some Water-Fowl In Loch-Turit is just one example. In more recent times, the incredible loch views have been used as dramatic filming locations. For example, you may recognise Loch Shiel as Hogwarts’ Black Lake in the Harry Potter movies and Loch Katrine has been used in the popular Outlander series.
