Lago di Lei

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 (municipality of Ferrera, Grisons) in 1955 after diplomatic talks, while an equivalent sized territory further north of the lake was ceded to Italy in the exchange. [1] 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.

The geography of Italy includes the description of all the physical geographical elements of Italy. Italy, whose territory largely coincides with the homonymous geographical region, is located in southern Europe and comprises the long, boot-shaped Italian Peninsula crossed by the Apennines, the southern side of Alps, the large plain of the Po Valley and some islands including Sicily and Sardinia. Italy is part of the Northern Hemisphere. Two of the Pelagie Islands are located on the African continent.

<span class="mw-page-title-main">Rhine</span> Major river in Western Europe

The Rhine is one of the major European rivers. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein, Swiss-Austrian, and Swiss-German borders. After that the Rhine defines much of the Franco-German border, after which it flows in a mostly northerly direction through the German Rhineland. Finally in Germany, the Rhine turns into a predominantly westerly direction and flows into the Netherlands where it eventually empties into the North Sea. It drains an area of 9,973 sq km and its name derives from the Celtic Rēnos. There are also two German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate.

<span class="mw-page-title-main">Endorheic basin</span> Closed drainage basin that allows no outflow

An endorheic basin is a drainage basin that normally retains water and allows no outflow to other, external bodies of water ; instead, the water drainage flows into permanent and seasonal lakes and swamps that equilibrate through evaporation. Endorheic basins also are called closed basins, terminal basins, and internal drainage systems.

<span class="mw-page-title-main">Vorderrhein</span> River in Canton of Graubünden, Switzerland

The Vorderrhein is one of the two sources of the Rhine. Its catchment area of 1,512 square kilometres is located predominantly in the canton of Graubünden (Switzerland). The Vorderrhein is about 76 kilometres (47 mi) long, thus more than 5% longer than the Hinterrhein/Rein Posteriur. The Vorderrhein, however, has an average water flow of 53.8 m3/s (1,900 cu ft/s), which is less than the flow of the Hinterrhein. According to the Atlas of Switzerland of the Swiss Federal Office of Topography, the source of the Vorderrhein—and thus of the Rhine—is located north of the Rein da Tuma and Lake Toma.

<span class="mw-page-title-main">Sources of the Rhine</span>

Lake Toma in the Swiss canton of Graubünden is generally regarded as the Source of the Rhine. Its outflow is called Rein da Tuma and after a few kilometers, it forms the Vorderrhein/Rein Anteriur. The course of this river is not particularly representative: after about two kilometers, its water is diverted into Curnera reservoir. The water is released at the Tavanase plant and flows into the Rhine at Ilanz. The river begins to be called Rhine in the vicinity of Chur, more specifically, at the confluence of the Vorderrhein and Hinterrhein/Rein Posteriur next to Reichenau in Tamins.

The border between the modern states of Switzerland and Italy extends for 744 kilometres (462 mi), from the French-Swiss-Italian tripoint at Mont Dolent in the west to the Austrian-Swiss-Italian tripoint near Piz Lad in the east. Much of the border runs across the High Alps, rising above 4,600 metres (15,100 ft) as it passes east of Dufourspitze, but it also descends to the lowest point in Switzerland as it passes Lago Maggiore at below 200 metres (660 ft).
