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.

|18,960 km2 7,320 sq mi||311 km 193 mi||244 m 801 ft||1,639 km3 393 cu mi|
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 where swimmers frequent during the warmer months. Like many other Great Lakes, this lake borders both the United States and Canada.
11. Lake Winnipeg

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.

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.
