There are thousands of beautiful lakes in the world, many of which provide perfect places to practice water sports such as sailing, wakeboarding and fishing. While many lakes are impressive because of their sheer size, others are extremely deep and home to a large collection of aquatic creatures. Here are the ten deepest lakes in the world.

If you head to the state of Oregon in the USA you will have the chance to visit this stunning body of water. Crate Lake is 594 metres deep and was formed when Mount Mazama collapsed more than seven thousand years ago. This lake is fed by snowfall and rain rather than rivers and all of the water in the lake is replaced roughly every 250 years.

8. Great Slave Lake (Canada) – 2,015 ft

Kyrgystan might not be your first choice of holiday destination, but this is where you will find the seventh deepest lake in the world. The lake measures 668 metres deep and is also the tenth largest lake in the world when measuring by volume.

6. Lake Malawi (Mozambique, Tanzania, Malawi)- 2,316 ft

This lake is so large and deep that it is actually found in three nations, namely Mozambique, Tanzania and Malawi. Known as Lake Nyasa in Tanzania, this body of water is 706 metres deep and is also the third largest lake in the whole of Africa.

5. O’Higgins Lake ( Chile, Argentina) – 2,742 ft

The exact name of this lake depends on who you talk to. While it is called O’Higgins lake by the people of Chile, in Argentina they call it the San Martin Lake. However, everyone agrees that the lake is 836 metres deep at its deepest point and that the shoreline measures a colossal 525 kilometres.

4. Lake Vostok (Antarctica) – 3,300 ft

Lake Vostok

The name of this lake makes Lake East in Russian and it is located underneath the surface of the enormous East Antarctic Ice Sheet. Like most things in this part of the world, the lake is extremely large, while it has a depth of a little under one thousand metres. However, the sheer depth of the lake and the harshness of the climate here makes getting an exact reading extremely difficult.

3. Caspian Sea (Iran, Russia, Turkmenistan, Kazakhstan, Azerbaijan)- 3,363 ft

The name of this mighty lake is actually very deceptive. Although its size has caused it to be named a sea, the fact that it is surrounded by land on all sides means that it is actually an incredibly big lake that is more than a thousand kilometres long. The Caspian Sea is also 1,025 metres deep, making it the third deepest lake in the world.

2. Lake Tanganyika (Tanzania, Democratic Republic of the Congo, Burundi, Zambia)- 4,823 ft

1. Lake Baikal (Russia) – 5,387 ft

Despite the impressive depths of the other lakes on the list, Lake Baikal has them all beat. This body of water is both the largest and deepest lake in the world and measures 1,642 metres deep, while it contains around 20% of the unfrozen fresh surface water in the world.
