The Rhône is a major river in France and Switzerland, arising in the Alps and flowing west and south through Lake Geneva and southeastern France before discharging into the Mediterranean Sea. At Arles, near its mouth, the river divides into the Great Rhône and the Little Rhône. The resulting delta forms the Camargue region.
The Grande Dixence Dam is a concrete gravity dam on the Dixence at the head of the Val d'Hérémence in the canton of Valais in Switzerland. At 285 m (935 ft) high, it is the tallest gravity dam in the world, fifth tallest dam overall, and the tallest dam in Europe. It is part of the Cleuson-Dixence Complex. With the primary purpose of hydroelectric power generation, the dam fuels four power stations, totaling the installed capacity to 2,069 MW, generating approximately 2,000 GWh annually, enough to power 400,000 Swiss households.
A moraine-dammed lake occurs when the terminal moraine has prevented some meltwater from leaving the valley. Its most common shape is that of a long ribbon. Example of moraine dammed lakes include:
Lake of Gruyère is an artificial lake in the La Gruyère region of the Canton of Fribourg, Switzerland.
Lago di Lei is a reservoir in the Valle di Lei, powering the Hinterrhein storage power stations. The reservoir is almost entirely in Italy, but the barrage was built on territory ceded by Italy to Switzerland in 1955 after diplomatic talks, while an equivalent sized territory further north of the lake was ceded to Italy in the exchange. The dam is operated by Kraftwerke Hinterrhein. The waters of the lake are the only waters in Italian territory that drain to the North Sea, being part of the Rhine's drainage basin. Other waters of Italy that do not flow to the Mediterranean Sea are found in the valley of Livigno, valley of Sexten, Puster Valley east of Innichen, and most of the waters of the municipality of Tarvisio east of Sella Nevea: all these waters flow to the Black Sea through the basin of the Danube.
Wägitalersee is an artificial lake in Wägital, a valley in the canton of Schwyz, Switzerland. The lake is surrounded by the mountains Gross Aubrig, Fluebrig, Zindlenspitz, Brünnelistock and Bockmattli. The reservoir is located in the municipality of Innerthal.
Klöntalersee is a natural lake in the canton of Glarus, Switzerland and covers the major part of the Klöntal valley floor. Since 1908, it has been used as a reservoir for electricity production. The dam's construction substantially increased the lake's volume.
Zervreilasee is a reservoir located south-west of Vals in the canton of Graubünden, Switzerland.
The Lac d'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 161 m. 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 162 MW La Bâtiaz Power Station, 12 km (7 mi) to the east in Martigny, Switzerland. The drop between the dam and La Bâtiaz Power Station is 1,400 m (4,593 ft).
The Dent du Géant is a mountain in the Mont Blanc massif in France and Italy.
Lai da Marmorera is a reservoir in the Grisons, Switzerland. It is part of the Parc Ela nature park.
Lac de Mauvoisin is a reservoir in the canton of Valais, Switzerland. The reservoir is formed by the Mauvoisin Dam, which is 250 metres (820 ft) high. The dam is currently the 11th highest in the world, and the 6th highest arch dam. It was built in 1951–1957, and raised by 13.5 metres (44 ft) in 1991.
Lago di Luzzone is a reservoir in Ticino, Switzerland. The reservoir has a volume of 108 million m³ and a surface area of 1.27 km2 (0.49 sq mi). It is located in the upper Blenio valley, in the municipalities of Ghirone and Aquila.
Lac de Tseuzier is an artificial lake in the canton of Valais, Switzerland. It is located in the municipalities of Ayent and Icogne. The reservoir has a volume of 51 mio m³ and a surface area of 0.85 km2 (0.33 sq mi). It was formed by the dams of Zeuzier and Proz-Riond built in 1957.
Lago di Ortiglieto is a reservoir in northwest Italy which straddles the Metropolitan City of Genoa in Liguria, and the Province of Alessandria in Piedmont.
The Lai da Ravais-ch is an Alpine lake located south of the Sertig Pass and west of the Sella da Ravais-ch, in the Swiss canton of Graubünden. The lake has an area of 0.093 km² and is located at 2,505 metres above sea level. It is located in the municipality of Bergün Filisur.
