Coedty Reservoir
Coedty Reservoir is a reservoir in Snowdonia, North Wales. It is fed by the waters of Afon Porth-llwyd which flows from Llyn Eigiau. The reservoir lies at a height of , and measures some in size. It contains brown trout. The original dam was built in 1924 to provide hydro-electric power to the aluminium smelting works in Dolgarrog. In 1925, the Eigiau dam broke, and the flood of water from that also burst Coedty dam. The resultant flood caused the loss of 16 lives in Dolgarrog. The dam was rebuilt in 1926, and altered again in 1956. Water from the reservoir, which has a catchment area of around 27 square kilometres, is carried via a 3 km large metal pipe down to the hydro-electric power-station in Dolgarrog. Coedty d ...

Snowdonia
Snowdonia or Eryri (), is a mountainous region in northwestern Wales and a national park of in area. It was the first to be designated of the three national parks in Wales, in 1951. Name and extent It was a commonly held belief that the name is derived from ("eagle"), and thus means "the abode/land of eagles", but recent evidence is that it means ''highlands'', and is related to the Latin (to rise) as leading Welsh scholar Sir proved. The term first appeared in a manuscript in the 9th-century , in an account of the downfall of the semi-legendary 5th-century king (Vortigern). In the Middle Ages, the title ''Prince of Wales and Lord of Snowdonia'' () was used by ; his grandfather used the title ''Prince of north Wales and Lord of Snowdonia.'' The name ''Snowdonia'' derives from '' Snowdon'', the highest mountain in the area and the highest mountain in Wales at . Before the boundaries of the national park were designated, "Snowdonia" was generally used to refer to a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum.

Afon Porth-llwyd
Afon Porth-llwyd is a river in Snowdonia in north-west Wales. It flows from Llyn Eigiau on the south-eastern edge of the Carneddau range to join the river Conwy. Its waters are trapped at Coedty reservoir before flowing down to pass under Pont Newydd in Dolgarrog. From Coedty reservoir some water is also diverted to Dolgarrog Power station (along with water from Llyn Cowlyd Llyn Cowlyd is the deepest lake in northern Wales. It lies in the Snowdonia National Park at the upper end of Cwm Cowlyd on the south-eastern edge of the Carneddau range of mountains, at a height of above sea level.

Llyn Eigiau
Llyn Eigiau is a lake on the edge of the Carneddau range of mountains in Snowdonia, Conwy, Wales. The name ''Eigiau'' is thought to refer to the shoals of fish which once lived here. Early maps refer to it as ''Llynyga''. It is thought that a small number of Arctic char exist in the lake (as they do in neighbouring Llyn Cowlyd) after they were transferred here from Llyn Peris, and certainly it is one of the few lakes in Wales to have its own natural brown trout. The lake is surrounded by mountains including Pen Llithrig y Wrach. Dam In 1911 a dam ¾ mile long and high was built across part of its eastern side to supply water for the power station at Dolgarrog, which in turn provided power for the adjacent aluminium works. Materials for the dam were transported along the newly laid Eigiau Tramway, which ran from Dolgarrog and utilized the route of the former Cedryn Quarry Tramway. The original contractor pulled out of the construction, alleging corner-cutting, and indeed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Dolgarrog
Dolgarrog is a village and community (Wales), community in Conwy County Borough, in Wales, situated between Llanrwst and Conwy, very close to the Conwy River. The village is well known for its industrial history since the 18th century and the Llyn Eigiau, Eigiau dam disaster, which occurred in 1925. The population was 414 at the 2001 Census, increasing to 446 at the 2011 Census. The community extends up to, and includes part of, Llyn Cowlyd in the Carneddau. The village is served by Dolgarrog railway station, a halt on the other side of the river Conwy, although the bridge allowing access to the station is slated for closure. Surf Snowdonia, the world's first commercial artificial surfing lake, is located in Dolgarrog on the site of the old aluminium factory. Across the valley is the crag of Cadair Ifan Goch. Etymology The name Dolgarrog derives from Welsh language, Welsh dôl (water-meadow) and carrog (torrent) and reflects the fact that a number of streams descend s ...

Eigiau Tramway
The Eigiau Tramway might refer to the Eigiau Quarry Tramway or to the Eigiau Reservoir Tramway. Eigiau Quarry Tramway The Eigiau Quarry Tramway was a narrow gauge, mile-long, horse-powered tramway which operated from c1863 to c1888 and served the Cwm Eigiau quarry (SH702635), near Llyn Eigiau in Caernarfonshire, Wales. The tramway was an extension of the Cedryn Quarry Tramway, operating from c1860 to serve the Cedryn slate quarry (SH719636), a little to the south-west of Llyn Eigiau. The tramway linked these two quarries to Dolgarrog in the Conwy valley. In 1861 the North Wales Chronicle referred to "Tenders invited to construct a tram-road long from Cwm Eigia icslate quarry to River Conwy". However, the tramway was initially only built as far as Cedryn, and in 1863 the ''Caernarvon & Denbigh Herald'' advertised for a contractor to extend west to Cwm Eigiau Quarry. It is entirely possible that the first reference to "Cwm Eigia slate quarry" was in fact a reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llyn Cowlyd
Llyn Cowlyd is the deepest lake in northern Wales. It lies in the Snowdonia National Park at the upper end of Cwm Cowlyd on the south-eastern edge of the Carneddau range of mountains, at a height of above sea level. The lake is long and narrow, measuring nearly long and about a third of a mile (500 m) wide, and covers an area of . It has a mean depth of and at its deepest has given soundings of , this being some greater than its natural depth, the water surface having been raised twice by the building of dams. The surrounding hills drop steeply to the water's edge, from Cefn Cyfarwydd and Creigiau Gleision to the east, and Pen Llithrig y Wrach to the west, and as a consequence have not been forested in the 20th century, as were the slopes of neighbouring Llyn Crafnant. Indeed, there is not a tree to be seen, and the general aspect is one of bleakness. Dependent on the weather conditions, the waters often appear dark. The supply of water to Llyn Cowlyd is assisted at its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
