The Mid Wales Regional Committee of the National Assembly for Wales covered the counties of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. If Mid Wales is classed as Ceredigion and Powys, the area would be 6,962 square kilometres (about the size of Cumbria). - Yr Wyddfa commonly known as Snowdon in English, is the highest mountain in Wales, at an elevation of above sea level, and the highest point in the British Isles south of the Scottish Highlands. It is located in Snowdonia National Park (") in Gwynedd, and has been described as "probably the busiest mountain in Britain". It is designated as a national nature reserve for its rare flora and fauna. - The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales from Devon and Somerset in South West England.

One of the shops was a well - stocked store owned by the Gregory brothers from Tideswell . Accommodation consisted of workmen 's huts , foremen 's huts and married workmen 's huts . The latter were decorated to a high standard , as photographs from the period confirm . The population rose to 900 people . Remnants of '' Tin Town '' can still be seen when walking to the west of Derwent Reservoir . The former railway track is now a footpath . A number of books and resources charting the history of Birchinlee and the dambuilders have been written by Professor Brian Robinson ( whose mother was born and lived in Tintown ) and Doctor Bill Beven , Peak District National Park archaeologist . The Derwent Valley Museum , located on the Derwent Reservoir dam and run privately by Vic Hallam , tells the history of the Derwent valley and of Derwent , Ashopton and Birchinlee as well as the tale of RAF Squadron 617 and its training for Operation Chastise ( the '' Dam Busters '' raids ) during the Second World War . Further up the valley is Beavers Croft , a 14th - century house stead that was occupied by the chief engineer of Howden Dam at the early part of the 20th century . It is currently owned by private business partners that let the house for self - catering holidays during the summer , and the barn is occupied by A.

MSL is a type of vertical datuma standardised geodetic reference pointthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location. - A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. - Sheffield is a city and metropolitan borough in South Yorkshire, England.

A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics.

Built mainly of concrete, the exterior of the dam face is dressed stone. The dam is a gravity dam. This type of dam needs to be built upon solid foundations as the pressure of the reservoir behind should be in equilibrium with the total weight of the dam itself thus causing complete stability. - Nottingham is a city and unitary authority area in Nottinghamshire, England, located south of Sheffield and north of Leicester. - A reservoir (etymology: from French "reservoir" a "storehouse" ) is a storage space for fluids.
