The 15 Largest Lakes in the World

Key Points

• A lake is generally deeper than a pond. 
• A lake also tends to be more of an oval shape with peninsulas, while ponds usually have rounded edges.
• Lakes are mostly freshwater but can contain some amounts of salt water, while ponds are freshwater. 

Thousands of lakes exist in the world today, and it’s only natural to wonder which of them is the largest. With modern technology, humanity has managed to measure lakes in terms of their size and volume. We have gathered data about the biggest lakes of all.

We’re going to show you the 15 largest lakes in the world and provide interesting information about each one.

What is a Lake?

Before we show you the biggest lakes in the world, we have to know what makes a body of water a lake. Generally speaking, the main differences between a lake and a pond are size, outlet, depth, shape, and type of water contained within:

1. Depth: A lake is generally deeper than a pond. 

2. Shape: A lake also tends to be more of an oval shape with peninsulas, while ponds usually have rounded edges.

3. Nature: Lakes are mostly freshwater but can contain some amounts of salt water, while ponds are freshwater. 

Furthermore, lakes tend to be:

• deeper than 20 feet
• have an open outlet that connects them to a body of water rather than being closed off
• 200 acres (0.3 sq mi) or more in overall size.

15 Largest Lakes in the World

Now that we know what makes a body of water a lake, it’s time to discover the largest ones. Interestingly, the largest lakes might not be the deepest nor the longest as you will see on this list. The 15 largest lakes in the world are:

15. Lake Balkhash

Lake Balkhash is a lake with a high density of saline, and it is located entirely in Kazakhstan. This lake is the center of a lot of economic projects. The crescent-shaped body of water is the largest lake in Kazakhstan and one of Asia’s big lakes.

The Aksu, Karatal, and Ili rivers flow into this large lake which shares the same name as the largest city on its northern shore.

Balkhash contains both salt and fresh water with its deeper eastern side containing the former, and its shallower, broader, western side, containing the latter.

14. Lake Ladoga

Lake Ladoga is often considered to be the largest lake in Europe but only because it is located entirely within Europe and not split into different regions. Lake Ladoga is also the second-largest lake in all of Russia (the largest is Lake Baikal).  

In terms of freshwater big lakes on a global scale, Ladoga ranks 14th. The body of water is yellow-brown and home to a wide range of fish, including, carp bream and European perch. It also has its very own ringed seal species, the Ladoga seal.

13. Lake Ontario

Lake Ontario is the 13^th largest lake, and it is another one that is split between the U.S. and Canada. Lake Ontario is another one of the Great Lakes, and it has the smallest surface areas of any of them. This lake is commonly used as a feat for swimmers to cross.

12. Lake Winnipeg

Lake Winnipeg is a very large lake that is located entirely within Canada. The lake is part of the largest watershed of any lake in Canada. Lake Winnipeg is facing significant ecological problems including infiltration by zebra mussels and algae blooms.  

11. Lake Erie

Lake Erie is another lake that borders the United States and Canada. It’s another one of the Great Lakes, and it’s the smallest out of all of them in terms of volume. The lake borders many states in the U.S., and it’s a popular tourist attraction throughout the year, even when portions freeze in the winter.

10. Great Slave Lake

The Great Slave Lake was named by French Explorers that dealt with Cree individuals who had enslaved other tribes. That name was later translated into English. This lake has a fair amount of area, but this is known mostly because it is the deepest lake in North America.

9. Lake Malawi

Although Lake Malawi is named after one country, it actually has shorelines is three. They are Malawi, Mozambique, and Tanzania. This lake has a respectable surface area, but its depth and volume are not too significant.

8. Great Bear Lake

Great Bear Lake is located in Canada. Although Canada has a lot of lakes, this one is the largest lake that is situated entirely in the country. This lake is in the far north of Canada, with some of it technically being in the Arctic Circle!

7. Lake Baikal

Lake Baikal is located exclusively in the country of Russia. Although it is seventh on this list, it is the deepest lake in the entire world, and it has the largest volume of freshwater in a lake in the world. This lake is very deep.  

6. Lake Tanganyika

Lake Tanganyika is another massive lake that is located on the continent of Africa. It has shorelines in Zambia, Tanzania, the Democratic Republic of Congo, and Burundi. No other freshwater lake is as long as this one, and its vast depths give it a massive volume. Lake Tanganyika is the largest freshwater lake by volume.

5. Lake Michigan

Lake Michigan is another one of the Great Lakes, and this one is interesting because it is located entirely within the confines of the United States. As such, this is the largest lake that is located in a single country! It also has more volume than Lake Huron.

4. Lake Huron

Lake Huron is another of the Great Lakes that has shorelines in the United States and Canada. This lake is interesting because it has less surface area than Lake Victoria, but it has a lot more volume. Lake Huron is interesting because it has Manitoulin Island, the biggest lake island in the entire world!

3. Lake Victoria

Lake Victoria is the largest lake in Africa. This freshwater lake has shorelines in Uganda, Kenya, and Tanzania. Lake Victoria was named for the British monarch, and it is famous for supporting a wide variety of wildlife in the area. Although its area is much larger than most other lakes around the world, its volume is substantially less owing to its short depth.

2. Lake Superior

Lake Superior has shorelines in both the United States and Canada, and it’s the largest freshwater lake in the world by surface area alone. This lake has a massive volume that exceeds many of the other “Great Lakes” that are nearby. Lake Superior has been used for shipping for over a century.

1. Caspian Sea

The Caspian Sea is the world’s largest lake even though it shares some characteristics with a sea, including salinity and the fact that it has an ocean basin below sea level. The lake has shorelines in many countries due to its large sizes, such as Kazakhstan, Russia, Iran, Turkmenistan, and Azerbaijan. The water in this lake is brackish in some parts with somewhat high salinity, but less than an ocean.  

What Is the Largest Lake in the United States?

Lake Superior is the largest lake in the United States, but it shares a shoreline with Canada, too. The largest lake contained entirely in the U.S. is Lake Michigan. This lake is located next to the state of Michigan.

Final Thoughts on the Largest Lakes in the World

The largest lakes in the world are distributed around the world. Many of the biggest lakes are found in North America, though. These lakes have an immense surface area, length, depth, and volume. Many of these lakes share shorelines with multiple countries, too. However, a few of these lakes are very large and only exist in a single country, like Lake Michigan.
