Loch Awe

Loch Awe 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 Awe rather than just read about it. In short: Loch Awe (Scottish Gaelic: Loch Obha; also sometimes anglicised as Lochawe, Lochaw, or Lochow) is a large body of freshwater in Argyll and Bute, Scottish Highlands. It has also given its name to a village on its banks, variously known as Loch Awe or Lochawe.

Key takeaways

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

Reference excerpt

Loch Awe (Scottish Gaelic: Loch Obha; also sometimes anglicised as Lochawe, Lochaw, or Lochow) is a large body of freshwater in Argyll and Bute, Scottish Highlands. It has also given its name to a village on its banks, variously known as Loch Awe or Lochawe. There are islands within the loch such as Innis Chonnell and Inishail.

The loch It is the third-largest freshwater loch in Scotland with a surface area of 38.5 square kilometres (14+7⁄8 sq mi). It is the longest freshwater loch in Scotland, measuring 41 kilometres (25 mi) from end to end with an average width of one kilometre (5⁄8 mi). The loch runs approximately south-west to north-east, roughly parallel to the two sea lochs of Loch Etive and Loch Fyne. Via the River Awe and Loch Etive it drains westward from its northern end and thus into the Atlantic Ocean. At the narrowest section of the loch are North Port (Taychreggan Hotel) and South Port (Portsonachan Hotel). Once used by cattle drovers, a ferry ran between these shores to facilitate crossing to markets beyond. The Transatlantic Cable, which runs through the village of Kilchrenan, was laid across at this point in 1955. There is an aquaculture site beside the loch at Braevallich.

Hydroelectric schemes Loch Awe is the site of two hydroelectric facilities. One, Inverawe power station (owned by SSE – formerly Scottish and Southern Energy, originally the North of Scotland Hydro-Electric Board 1943–1990), is a conventional hydro power scheme created by damming the River Awe in the Pass of Brander at Awe Barrage, and feeding the water through a large submerged tunnel; thus generating electricity as it emerges at the power station and rejoins the River Awe, flowing into Loch Etive. The turbine is of the Kaplan type, designed and constructed by Boving and Company of London, and develops 30.2 megawatts (40,500 brake horsepower). This drives a single 30.5 MW English Electric alternator via a vertical shaft. Water is also passed through the Awe Barrage, powering two Neyrpic 375 kW bulb turbines as it does so. In so doing, this water provides a constant flow into the upper River Awe. A fish pass also exists at Awe Barrage to allow the passage of spawning salmon into Loch Awe and beyond. Despite continued faith in fish passes since the 1800s, research shows that they hinder upstream migration of salmon. The young salmon (smolts), eventually pass downstream either through the Inverawe hydro power station or the barrage structure. The hydro station features a slow rotating Kaplan turbine, which delays the passage of smolts, discourages descent, and increases predation by fish such as pike and brown trout. Both Inverawe power station and the associated Awe Barrage were constructed by the North of Scotland Hydro Electricity Board during the late 1950s/early 1960s. The second is a more unusual pumped storage facility, using an artificial loch in the hills above Loch Awe. Water is pumped up to the top pool (the headpond), during times of surplus power; and released to power four pump/generators situated inside the mountain at times of peak demand. The second project, known as Cruachan from the name of the hill above, (Ben Cruachan) has a visitor centre, which includes tours into the heart of the mountain. This scheme has an installed power capacity of 440 MW, and an energy capacity of 7 GWh. It was built by the North of Scotland Hydro-Electric Board before transferring into the ownership of Scottish Power, where it remained for many years. It was acquired by the Drax Energy group in January 2019. A third project, located at Balliemeanoch, aims to store 45 GWh and deliver 1.5 GW for 30 hours.

Tourism Loch Awe is renowned for its trout fishing. Salmon pass through the loch, coming past the barrage in the River Awe and continuing into the River Orchy. Loch Awe contains several ruined castles on islands, and at the northern end has one of the most photographed castles in Scotland, Kilchurn Castle, which in summer may be visited by a short boat trip or by a one-half-mile (800-metre) walk from a small car park just after the bridge over the River Orchy. St Conan's Kirk and Chapel of St Fyndoca are located in Loch Awe.

History

One of the oldest Argyll clans, the Macarthurs, owned lands around Loch Awe which was populated in close proximity with MacGregors, Campbells and Stewarts. Clan Macarthur artefacts, including the four-poster state bed, are held at Inveraray Castle. It was from Loch Awe and surrounding area that Clan Campbell established itself as a powerful family. In 1308, Robert the Bruce defeated the Clan MacDougall at the Battle of the Pass of Brander downstream from the loch.

MV Loch Awe, currently under construction in Poland for use on Caledonian MacBrayne routes on the west coast of Scotland, is named after the loch.

Environs

The A85 road and the West Highland Line run along the northern bank of the loch, and the A819 follows the south-east bank for a short distance up to the village of Cladich. From there the single-track B840 runs for the remaining distance to the head of the loch at Ford and then joining the A816 a short distance north of Kilmartin. Similarly, on the north-west side an unclassified single-track road runs the full length from the A85 in Taynuilt to Ford.

Lochawe village and Loch Awe railway station At the northern tip of the Loch, a railway station was opened in 1880 when the Callander and Oban Railway passed that way, and a large luxury hotel was created (Loch Awe Hotel, 1871). There is also the Ben Cruachan Inn which used to be the coach-house for the hotel. A village has grown up around the hotel, essentially running along the single strip defined by the A85 road. A steamer service used to operate on the loch from the pier just below the hotel, stopping at Portsonachan, Taycreggan, Eredine and Ford. The village now includes St Conan’s Kirk, one of the most interesting pieces of Church architecture in Scotland. Confusingly, while the railway station is called Loch Awe, the village is contracted to Lochawe. The author Mary Stewart resided in her Lochard home, House of Letterawe, during the last several decades of her long life.

Worked examples

Example 1 — a first encounter with Loch Awe

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

In research
Loch Awe 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 Awe 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 Awe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater lochs of Scotland, Loch Awe, Lochs of Argyll and Bute, so understanding it makes those chapters shorter.
In everyday life
Look for Loch Awe 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.
