Loch Assynt

Loch Assynt is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Loch Assynt rather than just read about it. In short: Loch Assynt (Scottish Gaelic: Loch Asainn or Loch Asainte ) is a freshwater loch in Sutherland, Scotland, 8 kilometres (5.0 mi) north-east of Lochinver. Situated in a spectacular setting between the heights of Canisp, Quinag and Beinn Uidhe, it receives the outflow from Loch Awe, Loch Maol a' Choire, and Loch Leitir Easaidh.

Key takeaways

Loch Assynt belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Loch Assynt to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Loch Assynt from memory before moving on to harder problems.

Reference excerpt

Loch Assynt (Scottish Gaelic: Loch Asainn or Loch Asainte ) is a freshwater loch in Sutherland, Scotland, 8 kilometres (5.0 mi) north-east of Lochinver. Situated in a spectacular setting between the heights of Canisp, Quinag and Beinn Uidhe, it receives the outflow from Loch Awe, Loch Maol a' Choire, and Loch Leitir Easaidh. It discharges into the sea at Loch Inver, via the River Inver. The general trend of the loch is west-northwest and east-southeast, while the western end bends sharply at Lochassynt lodge to the southwest. The loch is 9.65 kilometres (6 mi) long, and about 1.5 kilometres (1 mi) in maximum breadth. The total area is approximately 800 hectares (1,980 acres) and its drainage basin is over 111 square kilometres (43 sq mi). The total volume of the loch is approximately 250 million cubic metres (9 billion cubic feet) and the maximum depth is 86 metres (282 feet). There is excellent fishing for trout, sea-trout, and salmon. Ardvreck Castle, once held by the MacLeods and Mackenzies, occupies a promontory on the north shore, west of Inchnadamph. The elevation of the loch's surface above sea level varies with the levels of rainfall but has been measured as 65.55 metres (215.1 ft).

The Mermaid of Assynt

Whispered amongst the locals of Inchnadamph, the area surrounding the castle, legend tells of MacLeod's lost daughter, Eimhir, and her continued presence at Loch Assynt. Instead of jumping to her death, they believe Eimhir plunged into the caverns of the loch and, hiding from the devil to whom she was promised, made a new home beneath the water's surface, becoming the elusive 'mermaid of Assynt'. The locals also use this legend to account for natural changes in the landscape. When the loch's water rise above their normal levels, legend tells that these are Eimhir's tears mourning her life lost on the land. Some even claim to have sighted her weeping on the rocks, her body now transformed into half woman, half sea creature. Some contest her form, instead calling her Selkie, the Nordic mythological figure of the sea, who must first shed tears into the water in order to become visible again to the human eye. The legend also accounts for the geology of Inchnadamph. Clootie, infuriated by the broken promise of marriage summoned meteoric rocks from Chaos to obliterate Inchnadamph and MacLeod's kingdom. It is thought that this legend bears some relationship with the scientific findings that indicate north west Scotland was struck by an object from space around 1.2 billion years ago. Geologists from Aberdeen university described the event; "[a] massive impact would have melted rocks and thrown up an enormous cloud of vapour that scattered material over a large part of the region around Ullapool. The crater was rapidly buried by sandstone which helped to preserve the evidence." These legends are invoked to offer some mythical explanation for the unique geological and topographical character of Inchnadamph. Another version of the tale of the mermaid of Assynt relates to the creation of the Moine Thrust belt. Some believe Clootie's rage produced a tectonic rumbling from the earths core, resulting in the thrust westwards of the European plate, which is understood by geologists to account for the Moine Thrust belt.

Worked examples

Example 1 — a first encounter with Loch Assynt

Start with the simplest possible case. Write down what Loch Assynt claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Loch Assynt before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Loch Assynt ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Loch Assynt

In research: Loch Assynt appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Loch Assynt in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Loch Assynt is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater lochs of Scotland, Inver catchment, Lochs of Sutherland, so understanding it makes those chapters shorter.
In everyday life: Look for Loch Assynt outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
