The canton says "over 600 lakes". Officially named and at least half a hectare in size, there are 236. Count every body of water, down to the smallest pond, and you get 3594. Both figures are right; they simply count different things.

Number of lakes in Grisons: 236

236 lakes of half a hectare or more, and yet the national map shows 3594 bodies of standing water in Grisons. The gap is not imprecision; it is a way of counting.

How we count: the ConvivaPlus lake method
  1. 13594 water surfaces appear in swisstopo's landscape model for the canton.
  2. 2393 of them are at least half a hectare (5,000 m²).
  3. 3389 carry an official name, however small.
  4. 4236 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 Grisons has 3594; count only lakes over one square kilometre and you get 10. Even a plain name such as "Weiher" counts as official: what decides is the entry in the swissNAMES3D gazetteer. Namesakes more than 50 m apart count separately, which is why "Obersee" in Arosa appears twice in the list. Our count states where the line is, so it can be checked.
