Loch Affric

Loch Affric 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 Affric rather than just read about it. In short: Loch Affric is a freshwater loch within Glen Affric, in the Highland council area of Scotland. It lies about 25 miles (40 km) southwest of Beauly.

Key takeaways

  • Loch Affric 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 Affric to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Loch Affric from memory before moving on to harder problems.

Reference excerpt

Loch Affric is a freshwater loch within Glen Affric, in the Highland council area of Scotland. It lies about 25 miles (40 km) southwest of Beauly. The loch sits in a national nature reserve known for being home to a number of rare species and the loch itself is popular for trout fishing. An annual duathlon is held on the banks of the loch in May and the loch has been widely used as the backdrop in films.

Geography Loch Affric is one of two large lochs within Glen Affric, further up the glen to the southwest of Loch Beinn a' Mheadhoin. The River Affric is the main inflow and outflow for both lochs. A number of smaller lochs surround Loch Affric. At the southwestern end sits Loch Coulavie located at the base An Tudair Beag and a slightly higher elevation. Also, at the southwestern end, the river Affric flows into the tiny loch of Loch na Camaig. At the northeastern side, Loch Pollan Fearna drains into Loch Affric. Much of the area around the loch is mountainous. To the north, is Sgùrr na Lapaich (1,074 m; 3,524 ft) and An Tudair (1,036 m; 3,399 ft), outlying Munro Tops of Mam Sodhail. To the south lie the Corbetts of Aonach Shasuinn (888 m; 2,913 ft) and Carn a' Choire Ghairbh (865 m; 2,838 ft).

Botany & wildlife

The loch sits within the Glen Affric national nature reserve, the banks of the loch are made up of woodland with a mixture of Scots pine, silver birch, and other pine trees. Wildlife, which is rare in Great Britain noted to live in the nature reserve includes pine marten, Scottish wildcat, otter, red squirrel and golden eagle. The Scottish crossbill is also known to live in significant numbers in the Scots pine on the shores of Loch Affric. Rare dragonfly are noted to be frequently seen near the shores of Loch Affric. These include azure hawker, downy emerald, brilliant emerald, northern emerald and white-faced darter. Loch Affric is home to brown trout with fishermen reporting an average weight of a catch at 8 ounces (230 g) up to around fish weighing 5 pounds (2.3 kg). During an average fishing season around 1,000 trout are caught on the loch. Fishing is restricted to boat fishing only with permission controlled by the nearby Glen Affric Lodge.

Hydro-electric development In 1929 the building of a hydroelectric dam by the Grampian electricity supply company on Loch Affric was considered. However, following public fallout regarding some schemes developed in the preceding decade in Perthshire changes were made by the board to the original scheme to flood Glen Affric. Instead of damming Loch Affric, the nearby Loch Benevean would be dammed by the North of Scotland Hydro-Electric Board in the late 1940s resulting in a level rise of only twenty-five feet (7.6 m) and only one residential property would be lost. In turn the process of building the dam was reported to create around two-thousand jobs.

Film Loch Affric has been used as a recording location for a number of Hollywood films. These include Victoria & Abdul (2017), Detective Pikachu (2019), Dog Soldiers (2002) and Valhalla Rising (2009).

Worked examples

Example 1 — a first encounter with Loch Affric

Start with the simplest possible case. Write down what Loch Affric 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 Affric 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 Affric 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 Affric

In research
Loch Affric 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 Affric 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 Affric is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater lochs of Scotland, Lochs of Highland (council area), Moray Firth catchment area, so understanding it makes those chapters shorter.
In everyday life
Look for Loch Affric 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.
