- Our measured 13,700 km² is 4.9% below Wikidata’s published figure of 14,400 km². Published areas of lakes and seas move with the water level and with what is counted, so a few percent is expected.

Sources and method
- Outline
- Natural Earth, 1:10m Geography Regions (geography_regions_polys), public domain (Geography Regions (geography_regions_polys)). Outlines of lakes are drawn at 1:10 million.
- Boundary
- A lake or a sea has no legal boundary of its own. The outline is a cartographic one, and the page says so by showing the measured area beside the published one.
- Area basis
- Measured outline: computed on the WGS84 ellipsoid from the full-detail outline and shown rounded. Published figure: Wikidata (CC0), fetched 2026-11-11. An outline is kept within 10% of the published figure and matched to other places automatically within 5%.
- Shore
- Countries whose Natural Earth outline contains or comes close to the water's outline; computed, not a statement of ownership.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and two can be laid over each other.
