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 the Smallwood Reservoir
- The Caspian Sea (called a sea or a lake, depending on the definition), the largest of the 104 lakes ranked on sizeversus, is 54.0× the size of the Smallwood Reservoir; the Smallwood Reservoir ranks 22nd.
- The Smallwood Reservoir sits between Lake Nicaragua (7,820 km²) and Reindeer Lake (6,720 km²) in the ranking.
- It is a reservoir, made by a dam, and the 2nd largest of the 14 reservoirs in this ranking.
- Counted as a country, the Smallwood Reservoir would be larger than 45 of the 212 countries listed on sizeversus and would rank 168th by area, between Lebanon (10,000 km²) and Palestine (6,070 km²).
- It is larger than 3 of the 51 US states and districts (the biggest of them is Delaware, 5,170 km²) and smaller than 48.
- It is larger than 1 of the 31 provinces and regions of China (the biggest of them is Shanghai, 6,750 km²) and smaller than 30.
- The closest Chinese province is Shanghai (6,750 km²): the Smallwood Reservoir is 1.04× the size of Shanghai.
- Wikidata records a volume of 28 km³. Poured over Brunei (5,720 km²), that water would stand 4.9 m deep.
- Its surface lies about 472 m above sea level (Wikidata).
- On a standard web map (Web Mercator), a place at 54°N is drawn about 2.9× too large in area, so the Smallwood Reservoir looks bigger there than it is.
- Laid out flat, the Smallwood Reservoir stretches about 190 km north to south and 236 km east to west.
- Our measured 7,030 km² is 7.6% above Wikidata’s published figure of 6,530 km². This difference is flagged for review: a lake’s outline may include islands or bays that the published figure leaves out, or the water level may differ. The outline is kept because it is within 10%, and this page is not matched automatically to any other.

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

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.
