Loch Brand

Loch Brand 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 Brand rather than just read about it. In short: Loch Brand or Loch of Boghall was a loch situated in a depression between the Grange Estate, Crummock, Hill of Beith Castle site and Boghall in the Parish of Beith, North Ayrshire, Scotland. The loch was fed by the Grange Burn and surface runoff, such as from the old rig and furrows indicated by Roy's Maps of the mid 17th century.

Reference excerpt

Loch Brand or Loch of Boghall was a loch situated in a depression between the Grange Estate, Crummock, Hill of Beith Castle site and Boghall in the Parish of Beith, North Ayrshire, Scotland. The loch was fed by the Grange Burn and surface runoff, such as from the old rig and furrows indicated by Roy's Maps of the mid 17th century. The loch was drained by the Boghall Burn that runs passed the 'Court Hill' and into Powgree Burn at Gateside.

History

Loch Bran or Brand was the name by which the Loch of Boghall was formerly known. The loch, drained in 1780, is one of the sources of the Powgree Burn and lay on the lands of Boghall and Hill of Beith.

Crannog In the bottom of the loch piles or stakes of oak or elm have been found at various times and are thought that these may be the remains of crannogs or connected with fishing on the loch. Dobie, writing in 1876 states that the loch was drained about 60 years ago, thus about 1826. The 'cut' through the natural dam that once held back the loch waters below Boghall is clearly visible. The Boghall Burn runs from a drainage ditch through this 'cut'.

Land improvements Land improvements and reclamation was taking place in many areas, for example in 1814 Barr Loch and the Aird Meadow was bunded and drained. Although the loch's drainage may have begun in the 15th century, Alexander Montgomerie, 10th Earl of Eglinton, was pursuing a number of agricultural improvements on his extensive estates in the 18th century and other landowners followed his example. Intensive drainage work may have taken place in the 1740s as part of the improvements undertaken to provide employment for Irish estate workers during the Irish potato famines of the 1740s and the mid 19th centuries. Many drainage schemes also date to the end of World War I when many soldiers returned en masse to civilian life. The nearby placenames of Bogholm, Bogside and Boghall are self-evident as an indicators of the nature of the area.

A dispute In 1482, when Loch Brand was the property of the monks of Kilwinning Abbey, it is recorded that the Abbot and Convent of Kilwinning took legal action against Robert Montgomerie and his brother John of Giffin Castle, William Montgomerie, Alexander Montgomerie and James Ker who were accused of dangerous destruction and down-casting of the fosses and dikes of the loch called Loch Brand. It is not recorded what the judgement was or the effect these actions had upon the size and depth of the loch.

Ownership

As stated, the loch and bordering lands once belonged to the monks of Kilwinning Abbey and to the Montgomeries of Broadstone who held the Lands of Boghall. In 1691 Hew Montgomerie held the lands and his son Mathew inherited them. The loch formed part of the Barony of Beith, which had been given to the monks in the twelfth century. The monks' Grange lay nearby in the vicinity of the present day Grangehill Estate. Yester Hill of Beith or Hill of Beith Castle was a successor to the lands owned by the monks, however the Cuninghames had sold the castle and lands of Hill of Beith by the end of the 17th century. In around 1798 Hugh Brown of Broadstone purchased the lands of Hill of Beith Castle and part of the loch lands.

Habitats The site is now represented by a low, marsh and reed covered area (less than 2 ha in extent) centred at NS 358 543 on the OS map. The Ordnance Survey maps of the mid 19th century indicate that the area was farming land devoid of marsh, bog, or wetland, however the area in 2010 is as stated above.

Worked examples

Example 1 — a first encounter with Loch Brand

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

In research: Loch Brand 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 Brand 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 Brand is common in secondary-school and first-year university syllabi. It links to neighbouring topics Former lochs, Freshwater lochs of Scotland, History of North Ayrshire, so understanding it makes those chapters shorter.
In everyday life: Look for Loch Brand 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.
