List of freshwater islands in Scotland

List of freshwater islands in Scotland 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 List of freshwater islands in Scotland rather than just read about it. In short: The freshwater islands in Scotland include those within freshwater lochs and rivers – including tidal areas, so the islands may not always be surrounded by freshwater. It has been estimated that there are at least 31,460 freshwater lochs in Scotland and that 1.9 per cent of the land surface is covered by freshwater.

Reference excerpt

The freshwater islands in Scotland include those within freshwater lochs and rivers – including tidal areas, so the islands may not always be surrounded by freshwater. It has been estimated that there are at least 31,460 freshwater lochs in Scotland and that 1.9 per cent of the land surface is covered by freshwater. The distribution has a north-west to south-east gradient, with the highest concentrations occurring on the islands of the Outer Hebrides. The more notable freshwater islands include Lochindorb Castle Island, Loch Leven Castle Island, St Serf's Inch and Inchmahome, each of which have had a role to play in Scottish history. Inchmurrin, the largest freshwater island in the British Isles, is in Loch Lomond, which contains thirty or more other islands. Various names are used repeatedly. "Inch" or Innis is a Scots word that can mean 'island' (although it is also used for terra firma surrounded by marsh). Similarly, Eilean is the Gaelic for 'island'. A common suffix for offshore islands in the north of Scotland is "-holm", derived from the Old Norse holmr, meaning a 'small and rounded islet'. This list excludes artificial crannógs and the numerous small freshwater islands with no recorded name.

Larger islands

This table includes all of the freshwater islands that exceed 35 hectares (86 acres) in size and/or are populated.

Inchlonaig and Inchcruin are classified by the National Records of Scotland as "inhabited islands but had no usual residents at the time of either the 2001 or 2011 censuses." It is likely that Eilean Aigas and Contin Island are inhabited, at least from time to time as well, although they were not listed as such by the Census in 2001 or 2011.

In mainland lochs

Loch Awe is Scotland's longest loch and abounds with islands and crannógs. Several of the islands are, or have in the past, been inhabited; there are two castles and the remains of a chapel on the islands. Inistrynich, Eilean na Maodail, Eilean Dubh and Liever Island are all promontories as opposed to islands despite their names. The loch's water levels have fluctuated so some of them may have been islands in recent history, as the promontory on which Kilchurn Castle stands once was. There may be up to sixty islands in the Loch Lomond including Inchmurrin, the largest freshwater island anywhere in the Britain and Ireland, and Inchconnachan, which has hosted a small population of Red-necked Wallaby since at least 1975. The isolated strongholds of Lochindorb Castle and Loch an Eilein Castle were once in the hands of the 14th century nobleman Alexander Stewart, the infamous "Wolf of Badenoch". There are numerous unnamed small islands in mainland lochs, including those where the water level has been artificially raised by the creation of dams for the production of hydro-electricity. This process has created new islands that would previously have been small eminences.

On offshore islands

Although there are many crannógs in the lochs of the Inner Hebrides there are relatively few substantive, naturally occurring islands and of those that exist many are unnamed. By contrast there are innumerable small islands in the estimated 7,500 lochs of the Eilean Siar, only a small proportion of which are named by the Ordnance Survey. The Orkney and Shetland archipelagos to the north are similarly lacking in freshwater islands. Law Ting Holm, now attached to Mainland Shetland, was the location of the national þing, or Norse parliament of Shetland.

In rivers

No part of Scotland is more than about 80.4 kilometres (50 mi) from the sea and as a result Scotland's rivers are neither very wide nor long (although Scotland has many substantial salt water estuaries called firths). The below are islands in freshwater, or where indicated, occasionally reached by high tides and in brackish water.

Former islands Broch of Clickimin was an islet in Loch of Clickimin just west of Lerwick in Shetland that is now attached to mainland Shetland by a stone causeway. Similarly, 5 kilometres (3.1 mi) to the northwest Law Ting Holm was an islet in Loch of Tingwall attached to mainland Shetland by a submerged stone causeway but with changing water levels of the loch it is now a promontory. Although thought to be the site of last þing held in Shetland it has never been excavated. There are several former islands in the Tay, created by natural silting and artificial reclamation including: Big Island, Bloody Inches near Murthly, North Inch and South Inch in Perth, Richards Islands, Sleepless Inch and The Inch near Inchtuthil.

Worked examples

Example 1 — a first encounter with List of freshwater islands in Scotland

Start with the simplest possible case. Write down what List of freshwater islands in Scotland 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 List of freshwater islands in Scotland 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 List of freshwater islands in Scotland 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 List of freshwater islands in Scotland

In research: List of freshwater islands in Scotland 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 List of freshwater islands in Scotland 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: List of freshwater islands in Scotland is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater islands of Scotland, Islands of Loch Lomond, Lists of islands of Scotland, so understanding it makes those chapters shorter.
In everyday life: Look for List of freshwater islands in Scotland 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.
