There are several thousand lakes in Switzerland, with estimations up to 7000, although those include very small water bodies, traditionally referred to as "lakes". 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. 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,
Bern,
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). == Main list ==
