The numbers

The area is measured from the outline drawn above, on the WGS84 ellipsoid; the published figure is shown beside it, and a water body is kept only if the two are within 10%. This one is between 5% and 10% apart, so it is flagged and no comparison is built for it automatically.

What the numbers say about Topozero

About the same size as

On the shore

Natural Earth’s outlines of Russia contain or lie within 4 km of the outline of Topozero. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

Outlines are drawn at true scale.
Sources and method
Outline
Natural Earth, 1:10m Lakes + Reservoirs, public domain (Lakes + Reservoirs). 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%.
Depth, volume, height
As recorded in Wikidata; a volume that cannot be right for the area and depth is left out.
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.
