U.S. Ranks Third Globally in Number of Lakes, Trailing Canada and Russia
The United States holds the third position worldwide in terms of the number of lakes, with 102,519 lakes, according to data based on HydroLAKES. This places the U.S. behind Canada, which leads with 879,763 lakes, and Russia, with 201,240 lakes. These figures include lakes covering at least 0.04 square miles (0.1 sq. km), excluding reservoirs and regulated lakes. The concentration of lakes in these northern countries is largely attributed to the geological impact of successive ice ages, which reshaped landscapes and created conditions conducive to lake formation. Together, Canada, Russia, and the U.S. account for over 83% of the 1.42 million lakes included in the dataset. While the U.S. has a significant number of lakes, the total lake area can differ from the lake count; for instance, Russia's total lake area includes the Caspian Sea, the world's largest lake by surface area.
