Lago di Lei (Lombard:Lach de Lei) is areservoir in theValle di Lei, powering the Hinterrheinstorage power stations. The reservoir is almost entirely inItaly, but the barrage was built on territory ceded by Italy toSwitzerland (municipality ofFerrera,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 byKraftwerke 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 theMediterranean Sea are found in the valley ofLivigno, valley ofSexten,Puster Valley east ofInnichen, and most of the waters of the municipality ofTarvisio east of Sella Nevea: all these waters flow to the Black Sea through the basin of the Danube.
