Lac Du Vieux Émosson
__NOTOC__ Lac du Vieux Émosson is a reservoir in Valais, Switzerland, in the municipality of Finhaut at an elevation of 2205 m. The lake drains into the reservoir Lac d'Émosson, 300 m below. In September 2014, an increase of the dam by 21.5 meters was completed. The capacity of the lake was thus doubled to 25 million m3. The larger capacity is used for the Nant de Drance pumped storage plant, for which Lac du Vieux Emosson forms the upper basin and Emosson reservoir the lower basin. The storage power plant went into operation on 1 July 2022, after 14 years of construction. The construction of the plant cost the equivalent of 2 billion euros. The installed capacity is 900 MW, and 20 GWh can be stored. The arch dam Vieux Émosson was completed in 1955. Efforts to raise the dam began in 2013. The lake forms the upper reservoir for the 900 MW Nant de Drance Hydropower Plant which began operations in 2022. See also *List of lakes of Switzerland *List of mountain lakes of Switz ...

Valais ( , ; ), more formally, the Canton of Valais or Wallis, is one of the cantons of Switzerland, 26 cantons forming the Switzerland, Swiss Confederation. It is composed of thirteen districts and its capital and largest city is Sion, Switzerland, Sion. Valais is situated in the southwestern part of the country. It borders the cantons of Canton of Vaud, Vaud and Canton of Bern, Bern to the north, the cantons of Canton of Uri, Uri and Ticino to the east, as well as Italy to the south and France to the west. It is one of the three large southern Alps, Alpine cantons, along with Ticino and Grisons. It is a bilingual canton, French and German being its two official languages. Traditionally, the canton is divided into Lower, Central, and Upper Valais, the latter region constituting the German-speaking minority. Valais is essentially coextensive with the valley of the Rhône from its headwaters to Lake Geneva, separating the Pennine Alps from the Bernese Alps, the two largest mount ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Lac D'Émosson
__NOTOC__ The Lac d'Émosson (Lake Émosson) is a reservoir in the canton of Valais, Switzerland. It is located in the municipalities of Salvan and Finhaut. The closest small city in Switzerland is Martigny. The lake has a surface area of 3.27 km2 and an elevation of 1,930 m. The maximum depth is 180 meters. The purpose of the Émosson Dam is hydroelectric power generation. Water from the reservoir first powers the 189 MW Vallorcine Power Station downstream and just over the border in Vallorcine, France. Water is then sent through a headrace tunnel to the 190 MW La Bâtiaz Power Station, to the east in Martigny, Switzerland. The drop between the dam and La Bâtiaz Power Station is . The first dam of Émosson (also known as Barberine Dam) was built in 1925. The current dam with a height of 180 m was constructed between 1969 and August 1973 and floods the old dam. The reservoir was fully impounded on 10 September 1975, it increased the reservoir's volume from 40 million m³ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 development ...

Nant De Drance Hydropower Plant
The Nant de Drance Hydropower Plant is a pumped-storage power station in the canton of Valais in Switzerland. It is within the municipality of Finhaut, district of Saint-Maurice and about southwest of Martigny. Construction on the power plant began in 2008 and it began operations in 2022. It is owned by Nant de Drance SA, a consortium of Alpiq (39%), SBB (36%), (15%) and (FMV) (10%). The US$1.9 billion plant has an installed capacity of 900 MW and an energy storage capacity of 20 GWh. Background On 25 August 2008, the Swiss Federal Department of Environment, Transport, Energy and Communications granted a building permit to Nant de Drance SA for the construction of the plant with a 600 MW design. Preliminary construction began in September 2008 but a concession was granted in April 2011 which allowed for a larger 900 MW plant. Excavation of the tunnels began in 2009 and the caverns commenced in 2010. Raising of the upper Vieux Emosson Dam began in Spring 2013. The underground p ...

Lakes Of Valais
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...
