Largest lakes & reservoirs in by acres
There is no widely-accepted minimum surface area that defines a lake. What LakeLubbers describes as a lake, you might call a pond. Acreage of a lake (or sometimes square kilometers) is most often measured at the top surface area when the lake is at normal elevation. The surface area can be considerably smaller or larger when lake levels are lower or higher than normal. North America’s Lake Superior is the world’s largest freshwater lake by this measure.The other measure of a lake’s size is the lake’s water volume. By that measure, the world’s largest freshwater lake is Lake Baikal in Siberia.
