Surface area in km²: the Largest Lakes set’s figure for its lakes, else Wikidata’s (P2046) where it fits the outline, else the area of the outline. Seasonal salt pans keep their recorded figure; their area varies. Every named lake Natural Earth maps at 1:10m (with its supplements for Europe, North America and Australia), and every lake of the Largest Lakes set. The Caspian Sea counts as a lake, as in that set; coastal lagoons (the Vistula Lagoon, the Black Sea limans) do not. Countries are those on its shores, from the outlines. Reservoirs only: lakes Natural Earth marks as reservoirs, or Wikidata records as one (an artificial lake behind a dam). Places are by geography: what lies in a dependency counts for its own region (Puerto Rico’s islands are the Caribbean’s, Réunion’s Africa’s), and Hawaii is in Polynesia.
