Dunglass Island is an uninhabited island in the River Conon south-west of the village of Conon Bridge in the Highlands of Scotland. At approximately 40 hectares (99 acres) in extent, it is one of Scotland's largest freshwater islands.

River Conon river in the United Kingdom

The River Conon is a river in the Highlands of Scotland. It begins at Loch Luichart, and flows in a south-easterly direction to be joined by the River Meig at Scatwell before passing through Loch Achonachie. It is joined by the Black Water at Moy Bridge, and the River Orrin at Urray, before flowing past Conon Bridge and into the Cromarty Firth.

Conon Bridge human settlement in the United Kingdom

Conon Bridge is a small village in the Highland region of Scotland. The current Gaelic name is likely a neologism: the bridge was not built until the early 19th century and some early gravestones show the name sgudal or scuddle. One suggested source is the Old Norse "sku dal", valley of the fine views.

Scottish Highlands Place

The Highlands is a historic region of Scotland. Culturally, the Highlands and the Lowlands diverged from the later Middle Ages into the modern period, when Lowland Scots replaced Scottish Gaelic throughout most of the Lowlands. The term is also used for the area north and west of the Highland Boundary Fault, although the exact boundaries are not clearly defined, particularly to the east. The Great Glen divides the Grampian Mountains to the southeast from the Northwest Highlands. The Scottish Gaelic name of A' Ghàidhealtachd literally means "the place of the Gaels" and traditionally, from a Gaelic-speaking point of view, includes both the Western Isles and the Highlands.

The island, which contains the site of an Iron Age fort, can be reached by a wooden road bridge accessed by a track leading from the farm of Dunglass on the west side of the river or across a footbridge that spans a weir at the south-west extremity of the island. [2] [3]

The Iron Age is the final epoch of the three-age system, preceded by the Stone Age (Neolithic) and the Bronze Age. It is an archaeological era in the prehistory and protohistory of Europe and the Ancient Near East, and by analogy also used of other parts of the Old World. The three-age system was introduced in the first half of the 19th century for the archaeology of Europe in particular, and by the later 19th century expanded to the archaeology of the Ancient Near East. Its name harks back to the mythological "Ages of Man" of Hesiod. As an archaeological era it was first introduced for Scandinavia by Christian Jürgensen Thomsen in the 1830s. By the 1860s, it was embraced as a useful division of the "earliest history of mankind" in general and began to be applied in Assyriology. The development of the now-conventional periodization in the archaeology of the Ancient Near East was developed in the 1920s to 1930s. As its name suggests, Iron Age technology is characterized by the production of tools and weaponry by ferrous metallurgy (ironworking), more specifically from carbon steel.

Following a substantial flood in 1892, Nairne described the island as follows: [4]

Port of Dunglass farm, about 100 acres (40 ha), consists of Dunglass Island in the river and the embankment here broke, with the result that over twenty acres was covered with a thick layer of gravel that renders it unfit for further tillage. The Conon channel used to be the larger of the two but a gravel bank was thrown across above the Islands, and the greatest part of the river, for a time flowed through the Dunglass channel. The diversion of the river caused enormous damage to salmon ova, as the breeding banks were left dry, and something like a million ova practically became useless.

In 2004, a £38,000 biodiversity project involving Scottish Natural Heritage, Conon District Salmon Fishery Board, Brahan Estates, the Highland Council and Ross and Cromarty Enterprise was undertaken. Dense plantation woodland was removed and 400 tonnes (390 long tons) of cobblestones repositioned to aid salmon spawning, which also benefited other river species such as lampreys. [5] This work restored an alder-lined channel through the island, which had become "defunct". [6] [7]

Scottish Natural Heritage is the Scottish public body responsible for the country's natural heritage, especially its natural, genetic and scenic diversity. It advises the Scottish Government and acts as a government agent in the delivery of conservation designations, i.e. national nature reserves, local nature reserves, long distance routes, national parks, Sites of Special Scientific Interest (SSSIs), Special Areas of Conservation, Special Protection Areas and the national scenic area.

Lamprey order of vertebrates, the lampreys

Lampreys are an ancient extant lineage of jawless fish of the order Petromyzontiformes, placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin lampetra, which may mean "stone licker", though the etymology is uncertain.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

River Wissey river in the United Kingdom

The River Wissey is a river in Norfolk, eastern England. It rises near Bradenham, and flows for nearly 31 miles (50 km) to join the River Great Ouse at Fordham. The lower 11.2 miles (18.0 km) are navigable. The upper reaches are notable for a number of buildings of historic interest, which are close to the banks. The river passes through the parkland of the Arts and Crafts Pickenham Hall, and further downstream, flows through the Army's Stanford Training Area (STANTA), which was created in 1942 by evacuating six villages. The water provided power for at least two mills, at Hilborough and Northwold. At Whittington, the river becomes navigable, and is surrounded by fenland. A number of pumping stations pump water from drainage ditches into the higher river channel.

Margaree River river in Canada

The Margaree River is a river on Cape Breton Island in Nova Scotia. The northeast branch of the river derives from the watershed of the Cape Breton Highlands, while the Southwest Margaree flows northeast from Lake Ainslie. The two branches join at Margaree Forks. The river then flows north to empty into the Gulf of Saint Lawrence at Margaree Harbour, Nova Scotia. The river is 120 km in length and drains an area of 1,375 km². The Margaree has been well known for a century for its trout and Atlantic salmon sport fishery, that draws anglers from near and far. Fishing is highly regulated now and is restricted to fly fishing only, with barbless hooks, in the main stem of the river. Famed American angler and Atlantic salmon conservationist Lee Wulff caught his first salmon on a fly on the Margaree in 1933.

Lunga (Slate Islands) one of the Slate Islands in the Firth of Lorn in Argyll and Bute, Scotland

Lunga is one of the Slate Islands in the Firth of Lorn in Argyll and Bute, Scotland. The "Grey Dog" tidal race, which runs in the sea channel to the south, reaches 8 knots in full flood. The name 'Lunga' is derived from the Old Norse for 'isle of the longships', but almost all other place names are Gaelic in origin. The population was never substantial and today the main activity is an adventure centre on the northern headland of Rubha Fiola. The surrounding seas are fished for prawns and scallops and there is a salmon farm off the south eastern shores. The Special Area of Conservation of which the island is part hosts a growing number of outdoor leisure pursuits.

Salt River (California) formerly navigable hanging channel of the Eel River in the U.S. state of California

The Salt River is a formerly navigable hanging channel of the Eel River which flowed about 9 miles (14 km) from near Fortuna and Waddington, California, to the estuary at the Pacific Ocean, until siltation from logging and agricultural practices essentially closed the channel. It was historically an important navigation route until the early 20th century. It presently intercepts and drains tributaries from the Wildcat Hills along the south side of the Eel River floodplain. Efforts to restore the river began in 1987, permits and construction began in 2012, and water first flowed in the restored channel in October 2013.
