There are thousands of lakes in the world, and with modern technology, we can calculate the water volume and size of these lakes with relative ease. Now that we know the size of every lake, we can answer the question, ‘What is the largest lake in the world?’
What Is a Lake?
Before we can explain what the largest 12 lakes are, we need to know what makes a lake a lake. If we take a pond, we see that a lake differs through the following factors:
- Depth – A lake is much deeper than a pond.
- Shape – A lake usually takes the form of an oval or a more complex shape, whereas a pond is typically rounder.
- Contents – Ponds always contain freshwater, while lakes tend to have some salt even though they are still classed as freshwater.
The primary factor that makes a lake a lake is that the water has an opening somewhere that leads to the ocean while the rest of the contents are closed off by land. A lake also reaches a depth of at least 20 feet and a size of 200 acres or more.
12 Largest Lakes in the World Ranked
Lakes vary significantly in depth and size. This article explores 12 of the largest lakes in the world.
Area: 371,000 Km2
Deepest Point: 1,025 m
The Caspian Sea has features of both a sea and a lake. It’s the world’s largest lake and the largest inland water body. For its immense size, it’s also considered a full-fledged sea.
The lake borders Iran, Azerbaijan, Turkmenistan, Russia, and Kazakhstan. This endorheic basin sits 27 meters below sea level and has a water volume of 78,200 km3. Its deepest end is 1,025 meters, and its average length is 1,199 kilometers.
Interestingly, the Caspian Sea isn’t a freshwater lake. It’s partially salty, although only 30 percent as salty as seawater. The Caspian Sea’s tributaries include the River Volga, Kura River, and Ural River. This lake is the ancient remnant of the Paratethys Sea. Due to its size, the Caspian Sea has its ecosystem.
The Caspian Seal and Caspian Turtle are among the many species that consider the Caspian Sea home. Presently, it’s celebrated for its prominent oil industry and exceptional caviar.
Area: 82,100 km2
Deepest Point: 406.3 m
Lake Superior is located in Canada and the United States. It covers an area of 82,100 Km2 and has a maximum depth of 406.3 meters. With a total length of 616 kilometers, Lake Superior is the second-largest freshwater lake on Earth and the largest of the North American Great Lakes. This lake is so large that it drains into the nearby Lake Huron.
Lake Superior borders the United States and Canada. The states bordering Lake Superior include Michigan, Wisconsin, and Minnesota. The lake holds an impressive 12,100 km3 of water, accounting for 10 percent of the world’s surface freshwater. Lake Superior’s water volume exceeds that of four Great Lakes combined.
Lake Superior is a prominent hotspot on the Great Lakes Waterway, ferrying materials and goods across the water. Given its extreme depths exceeding 400 meters at some points, it’s considered to be the most dangerous lake to swim in on Earth.
Area: 68,870 km2
Deepest Point: 84 m
Lake Victoria is the third-largest lake on Planet Earth and the second-largest freshwater lake in the world. It’s also Africa’s largest lake. The lake was originally known as Lake Nyanza until 1858 when John Hanning Speke, a British explorer, discovered it and renamed it in honor of Queen Victoria.
Lake Victoria’s shoreline length is 7,142 kilometers. It has a maximum depth of 84 meters. Of the lake’s 12,100 km3 total volume, 20 percent comes from relatively small rivers flowing into the lake, while a whopping 80 percent comes from direct rainfall.
Lake Victoria borders Rwanda, Kenya, Tanzania, Burundi, and Uganda. It hosts over 3,000 islands. There are also numerous reefs and archipelagos within this freshwater lake. The animals living around Lake Victoria include:
- Giant otter shrew
- Cane rats

- Marsh mongoose
- Spotted-necked otter
- African clawless otter
Area: 59,600 km2

Deepest Point: 280 m
Lake Michigan, meaning “Great Water,” is the fifth-largest lake in the world and is among North America’s five Great Lakes. It’s the third-largest by surface area and the second-largest by volume of the Great Lakes. It’s also the only Great Lake located entirely in the US. This lake extends to a maximum depth of 280 meters.
Lake Michigan’s total volume is 4,900 km3. Its total length is 494 kilometers. The lake spreads west to east across Wisconsin, Illinois, Indiana, and Michigan. Lake Michigan’s shores touch numerous local and national parks.
Swimming in this lake is dangerous for many reasons. Its bottom is uneven, with deep drop-offs and holes. Its shoreline is also prone to deadly rip currents. Just a handful of Lake Michigan’s beaches have lifeguards.
Area: 32,600 km2
Deepest Point: 1,470 m
Lake Tanganyika is the second-largest of the African Great Lakes and the sixth-largest lake in the world. This 676-kilometer-long lake has numerous superlatives associated with its name.

- Kavala Island
Area: 31,500 km2
Deepest Point: 1,637 m
Lake Baikal is notorious for its maximum depth of 1,637 meters. Although it’s not the largest lake by surface area, it’s typically the deepest by volume. This lake is located in southern Siberia, Russia. It accounts for nearly a quarter of the world’s unfrozen fresh water.
Lake Baikal’s shoreline length is 2,100 kilometers, and it is typically the world’s seventh-largest lake and the world’s largest freshwater lake by volume. It contains more water than all other North America’s Great Lakes combined. It’s also considered one of the clearest lakes in the world.
Lake Baikal is among the few lakes with sufficient oxygenated water to sustain life at its greatest depths. It’s home to over 1,700 animal and plant species. On a clear day, the lake’s visibility increases to a depth of 39 meters. The lake hosts a total of 27 islands.
