This article contains a sortable table listing all major lakes of Switzerland. The table includes all still water bodies, natural or artificial, that have a surface area of at least 30 hectares (74 acres), regardless of water volume, maximum depth or other metric. These lakes are ranked by area, the table including also the elevation above sea level and maximum depth. They are either natural (type N), natural but used as reservoirs (NR) or fully artificial (A). For a list of artificial lakes only, see List of dams and reservoirs in Switzerland. For a list of lakes above 800 metres (2,600 ft) that includes smaller water bodies, see List of mountain lakes of Switzerland.
Along with the mountains, lakes constitute a major natural feature of Switzerland, with over 1,000 km (620 mi) of shores within the country. [Nb 1] Lakes, large and small, can be found in almost all cantons and provide an important source of water, leisure opportunities, as well as suitable habitat for fish-eating birds. The two most extensive, Lake Geneva and Lake Constance, are amongst the largest in Europe and mark the border of the Swiss Plateau, along with the Alps and the Jura Mountains. The largest wholly Swiss lake is Lake Neuchâtel. The remaining lakes over 100 km2 (39 sq mi) are Lake Maggiore and Lake Lucerne. In total 103 lakes exist that are more than 30 ha (74 acres) in surface area, and a considerable number of smaller lakes. All these lakes are found in the four major river basins of Switzerland: Rhine, Rhone, Po and Danube, [Nb 2] at almost all elevations below the permanent snow line.
There are several thousand lakes in Switzerland, with estimations up to 7000, [1] although those include very small water bodies, traditionally referred to as "lakes". [Nb 3] On this list, only the 103 largest lakes, which are over 30 hectares in area, are included. Among these, 58 are over 1.0 km2, 17 are over 10 km2, and just five are over 100 km2 in area. Of these lakes, 37 are natural, 21 are natural, but are used as reservoirs, and 45 are manmade reservoirs. These 103 lakes are shared among 21 cantons, out of the 26. [Nb 4] Some of these lakes are also shared with neighboring France, Germany, Austria, and Italy (for simplicity purposes, only the total area of the lake is indicated). Four of the cantons (Grisons, Berne, Valais, and Ticino) have more than 10 of the lakes, apiece, and just over one-half of the cantons (14) have one or more lakes of over 100 km2 in area. Most of these lakes are either below 800 metres above sea level (mostly natural lakes), or above 1600 metres (mostly manmade lakes). A large majority of the lakes, 66, are located in the Rhine basin (partly via the Aare River); 17 in the Rhone basin (partly via the Doubs River); 14 in the Po River basin (mostly via the Ticino River); and six are in the Danube River basin (all via the Inn River).

The geography of Switzerland encompasses the geographical features of Switzerland, a mountainous and landlocked country located in Western and Central Europe. Switzerland's natural landscape is marked by its numerous lakes and mountains. It is surrounded by five countries: Austria and Liechtenstein to the east, France to the west, Italy to the south and Germany to the north. Switzerland has a maximum north–south length of 220 kilometres (140 mi) and an east–west length of about 350 kilometres (220 mi).
The Alpine region of Switzerland, conventionally referred to as the Swiss Alps, represents a major natural feature of the country and is, along with the Swiss Plateau and the Swiss portion of the Jura Mountains, one of its three main physiographic regions. The Swiss Alps extend over both the Western Alps and the Eastern Alps, encompassing an area sometimes called Central Alps. While the northern ranges from the Bernese Alps to the Appenzell Alps are entirely in Switzerland, the southern ranges from the Mont Blanc massif to the Bernina massif are shared with other countries such as France, Italy, Austria and Liechtenstein.
Ticino, sometimes Tessin, officially the Republic and Canton of Ticino or less formally the Canton of Ticino, is one of the 26 cantons forming the Swiss Confederation. It is composed of eight districts and its capital city is Bellinzona. It is also traditionally divided into the Sopraceneri and the Sottoceneri, respectively north and south of Monte Ceneri. Red and blue are the colours of its flag.
The river Ticino is the most important perennial left-bank tributary of the Po. It has given its name to the Swiss canton through which its upper portion flows.
The Grisons or Graubünden, more formally the Canton of the Grisons or the Canton of Graubünden, is one of the twenty-six cantons of Switzerland. It has eleven districts, and its capital is Chur. The German name of the canton, Graubünden, translates as the "Grey Leagues", referring to the canton's origin in three local alliances, the Three Leagues. The other native names also refer to the Grey League: Grischùn in Sutsilvan, Grischun in the other forms of Romansh, and Grigioni in Italian. Rhaetia is the Latin name for the area. The Alpine ibex is the canton's heraldic symbol.
Valais, more formally the Canton of Valais, is one of the 26 cantons forming the Swiss Confederation. It is composed of thirteen districts and its capital and largest city is Sion. The flag of the canton is made of thirteen stars representing the districts, on a white-red background.
Lake Neuchâtel is a lake primarily in Romandy, the French-speaking part of Switzerland. The lake lies mainly in the canton of Neuchâtel, but is also shared by the cantons of Vaud, Fribourg, and Bern. It comprises one of the lakes in the Three Lakes Region, along with lakes Biel/Bienne and Morat/Murten.
The canton of St. Gallen or St Gall is a canton of Switzerland. Its capital is St. Gallen.
The Kura is an east-flowing river south of the Greater Caucasus Mountains which drains the southern slopes of the Greater Caucasus east into the Caspian Sea. It also drains the north side of the Lesser Caucasus, while its main tributary, the Aras, drains the south side of those mountains. Starting in northeastern Turkey, the Kura flows through Turkey to Georgia, then to Azerbaijan, where it receives the Aras as a right tributary, and enters the Caspian Sea at Neftçala. The total length of the river is 1,515 kilometres (941 mi).
The Reuss is a river in Switzerland. With a length of 164 kilometres (102 mi) and a drainage basin of 3,426 square kilometres (1,323 sq mi), it is the fourth largest river in Switzerland. The upper Reuss forms the main valley of the canton of Uri. The course of the lower Reuss runs from Lake Lucerne to the confluence with the Aare at Brugg and Windisch.
The Grimsel Pass is a mountain pass in Switzerland, crossing the Bernese Alps at an elevation of 2,164 metres (7,100 ft). The pass connects the Haslital, the upper valley of the river Aare, with the upper valley of the Rhône. In so doing, and as the Aare is a tributary of the Rhine, the pass crosses the continental divide between the North Sea and the Mediterranean Sea.
The Sihl is a Swiss river that rises near the Druesberg mountain in the canton of Schwyz, and eventually flows into the Limmat in the centre of the city of Zürich, after crossing the Zürich–Winterthur railway at Zürich HB. It has a length of 73 km (45 mi), including the Sihlsee reservoir, through which the river flows. Water is abstracted from the river at the Sihlsee, leading to decreased downstream water flows and a consequent reduction in water quality.
The Trebišnjica is a river in Bosnia and Herzegovina, and the right tributary of the Neretva. Before it was utilized for hydro exploitation via various hydrotechnical interventions and systems with different purposes, Trebišnjica used to be a sinking river, rising and sinking through its course before resurfacing at various places from the Neretva river below the Čapljina to the Adriatic coast, and along the coast from the Neretva Delta to Sutorina.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
Lake Qaraoun is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61 m-high (200 ft) concrete-faced rockfill dam in the middle reaches of the Litani River. The reservoir has been used for hydropower generation, domestic water supply, and for irrigation of 27,500 ha.
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.
Lai da Sontga Maria is a lake, located north of the Lukmanier Pass in Switzerland. It lies almost entirely in the municipality of Medel, a tiny fraction of the south-west part of the lake belonging to the municipalities of Quinto and Blenio. The reservoir has a surface area is 1.77 km2 (0.68 sq mi). The arch dam Santa Maria, which is to the north of the lake, was completed in 1968. The main road of the Lukmanier Pass runs along the eastern shore of the lake.
A lake is a naturally occurring, relatively large and fixed body of water on 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, like the much larger oceans, they form part of the Earth's water cycle by serving as large standing pools of storage water. Most lakes are freshwater 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.
The hydrology of Hungary, is mostly determined by Hungary's lying in the middle of the Carpathian Basin, half surrounded by the Carpathian Mountains. All parts of the country have some outflow. All surface water gravitates towards its southern center, and from there, is united in the Danube, which flows into the Black Sea. The whole of Hungary lies within the Danube drainage basin.
