The 12 Largest Freshwater Lakes in the World

Key Points

• Lake Winnipeg which is the remnant of a former glacier supports an abundance of wildlife living in the area. 
• Lake Malawi is a meromictic lake because its different layers of water do not mix. It also contains the greatest variety of fish compared to any other lake on the globe.
• Lake Baikal is the world’s deepest lake with a depth that exceeds 5,000 feet.

Most of the world’s drinkable water is contained in freshwater lakes. Although it may seem like the amount of freshwater is small compared to saltwater, and it is, there is still a lot of fresh water in the world. To help you better understand the presence of fresh water in the world, we’re going to look at the 12 largest freshwater lakes in the world. These are the largest bodies of water that are not brackish or saline!

What Are Freshwater Lakes?

Freshwater lakes are lakes that contain freshwater that is neither brackish nor saline. While we’re on the topic, we have to ask another question: what is a lake? A lake is a body of water that has the following qualities:

• Depth: Lakes are deeper than ponds, reaching at least 20 feet in depth in most cases.
• Shape: Lakes have a more oval-like shape than ponds
• Water Type: Lakes are mostly freshwater, but they can also be brackish or saline. Ponds are solely freshwater.
• Open outlet: Lakes have an opening to other bodies of water from which they derive their water.
• Size: Lakes are typically larger than 0.3 square miles.

Lakes are very distinct from ponds because they are larger, have an open outlet, and have a certain depth.

The 12 Largest Freshwater Lakes in the World

The lakes on our list will vary from about the size of New Jersey all the way up to Great Lakes which are more than 20,000 square miles. Let’s dive into the 12 largest freshwater lakes in the world!

12. Lake Ontario

Lake Ontario is the smallest one of the Great Lakes by area alone. However, it does have significant depth and volume compared to some of the other Great Lakes. This lake is known for being a tourist attraction and a place that swimmers frequent during the warmer months. Like many other Great Lakes, this lake borders both the United States and Canada.

11. Lake Winnipeg

Lake Winnipeg is a large lake that only lies in the country of Canada. The lake is a remnant of a former glacier, and many forms of wildlife live in the area. This freshwater lake is known for having the largest lake watershed of any in Canada, and it even receives water from various states in the U.S. Its watershed is almost 400,000 square miles!

10. Lake Erie

Lake Erie is one of the Great Lakes, and it shares a shoreline with the United States and Canada. In terms of volume, Lake Erie is the smallest of all the Great Lakes, but it has a larger area than Lake Ontario. A large portion of this lake freezes over every year, so people come from far away to enjoy the scenery.

9. Great Slave Lake

The Great Slave Lake is a lake with a very unfortunate name that originates from the days of the fur trade in the 18^th century. The name refers to the Cree enslavement of other tribes. The lake is located in the far northern reaches of Canada, and it’s known for being the deepest lake in all of North America at a depth of some 2,014 feet! The lake is known for being the location of Operation Morning Light, a recovery of nuclear materials.

8. Lake Malawi

Located in Mozambique, Malawi, and Tanzania, Lake Malawi is an important freshwater lake for drinking water and transportation. Lake Malawi has more species of fish living in it than any other lake in the world. An interesting tidbit about this lake was that it was the site of Britain’s first naval battle in World War I. Also, it’s a meromictic lake, and that means its different layers of water do not mix.

7. Great Bear Lake

The Great Bear Lake is another massive lake located in northern Canada. This is the largest lake that is located entirely within the nation of Canada. The lake is surrounded by a massive forest. This lake is known for having a section of an ice crossing located on the lake. The lake is known for its large area and depth. 

6. Lake Baikal

Lake Baikal is known for being the world’s deepest lake, with a maximum depth that exceeds 5,000 feet. The lake is located in Siberia, Russia, making it a rather remote but also important tourist destination. Several villages are near Lake Baikal, and they serve as ecotourism destinations for people that want to see unique ice formations and hike in pristine nature. However, the lake is beginning to suffer from pollution in the form of algae blooms, liquid waste, and more.

5. Lake Tanganyika

Lake Tanganyika is the second-largest freshwater lake by volume alone, only falling behind Lake Baikal. This is also the world’s longest freshwater lake, reaching lengths of over 400 miles. The lake is located in Tanzania, Burundi, the Democratic Republic of the Congo, and Zambia. Lake Tanganyika is incredibly important in terms of ecology and biology.

4. Lake Michigan

Lake Michigan is the largest lake located wholly in the United States. This lake can be considered the same as Lake Huron which lies to its east and is joined by the Straits of Mackinac. However, these two lakes are often considered separate. The lake is massive and serves as a source of drinking water for people all along the borders of the lake. The lake is also the home of commercial fisheries and shipping outcomes.

3. Lake Huron

Lake Huron is one of the Great Lakes in the United States, and it is becoming more commonly considered as a single lake along with Lake Michigan. However, as an individual lake, it’s the third-largest freshwater lake in the world. The lake is known for its treacherous waters and the fact that over 1,000 shipwrecks are present in the waters.

2. Lake Victoria

Lake Victoria is the largest lake in Africa, and it’s considered one of the African Great Lakes. The lake is located in Kenya, Uganda, and Tanzania. The waters are home to unique species of fish that are not found anywhere else. The lake is somewhat shallow compared to the other largest lakes out there, but it’s also important for drinking water as well as transport.

1. Lake Superior

Lake Superior is the largest freshwater lake in the world, reaching over 31,000 square miles in size and boasting a depth of 1,300 feet at its deepest point. This great lake is split between the United States and Canada. The lake became significant to the shipping of manufactured materials in the 19^th century and also has many shipwrecks beneath its waves.
