Number of lakes in Schwyz: 15

15 lakes of half a hectare or more, and yet the national map shows 222 bodies of standing water in Schwyz. The gap is not imprecision; it is a way of counting.

How we count: the ConvivaPlus lake method
  1. 1222 water surfaces appear in swisstopo's landscape model for the canton.
  2. 227 of them are at least half a hectare (5,000 m²).
  3. 319 carry an official name, however small.
  4. 415 are both, named and at least 0.5 ha. That is what we count as a lake.

Anyone reading a different figure has almost always drawn a different line: count every water surface and Schwyz has 222; count only lakes over one square kilometre and you get 6. Even a plain name such as "Weiher" counts as official: what decides is the entry in the swissNAMES3D gazetteer. Our count states where the line is, so it can be checked.
