Lac De Mauvoisin
__NOTOC__ Lac de Mauvoisin is a reservoir in the canton of Valais, Switzerland. The reservoir is formed by the Mauvoisin Dam, which is high. The dam is the 11th highest in the world, and the 6th highest arch dam. It was built in 1951–1957, and raised by in 1991. The reservoir lies in the upper Val de Bagnes, between the massif of the Grand Combin, one of the highest mountains of the Alps, and La Ruinette. The highest peak visible from the lake is the Combin de la Tsessette ().

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.

Mauvoisin Dam
Mauvoisin Dam is a concrete variable radius arch dam across the Val de Bagnes on the Dranse de Bagnes stream, in the canton of Valais, Switzerland. Initial construction on the dam commenced in 1951 and was completed in 1957, with the reservoir filling by 1958. In 1991, the dam was raised to increase the capacity of the reservoir for winter storage. The dam's primary purpose is hydroelectric power generation. The eighth highest dam in the world, Mauvoisin stands high and long, with a structural volume of . The impounded water behind the dam forms the Lac de Mauvoisin, which has a capacity of 211.5 million m3 (171,500 acre feet) and a full surface area of . The dam and reservoir control runoff from a catchment of . Flood waters are released by a gated spillway with a capacity of . Water from the dam is fed to two hydroelectric power stations with a combined capacity of 363 megawatts (MW).

Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The developme ...

Grand Combin
The Grand Combin is a mountain massif in the western Pennine Alps in the canton of Valais. At a height of the summit of ''Combin de Grafeneire'' is one of the highest peaks in the Alps and the second most prominent of the Pennine Alps. The Grand Combin is also a large glaciated massif consisting of several summits, among which three are above 4000 metres (''Combin de Grafeneire'' , ''Combin de Valsorey'' , ''Combin de la Tsessette'' ). The highest part of the massif is wholly in Switzerland, although the border with Italy lies a few kilometres south. The normal route starts from the Panossière Hut, which lies on the north side in the Corbassière valley. Despite the fact that no major difficulties exist, a particularly dangerous passage has to be traversed on the north flank: ''Le Corridor''. It is a couloir dominated by seracs continuously falling on it.Helmut Dumler,Willi P. Burkhardt, ''Les 4000 des Alpes'', Geography The massif of the Grand Combin lies in Lower Valais, ...
