The lake is frozen for approximately five months of the year, from January to May, and during this time, it is possible to walk, skate, or drive across the ice. The lake’s frozen surface is also used as a transportation route during the winter months.

The water in the lake contains a high concentration of Oxygen and Nitrogen. Microbes have been found in the ice core drillings and the frozen lake water, which suggests the presence of life. The lake is protected by Environmental Groups, which claim that ice drilling machines contaminate the water underneath the ice.

5. O’Higgins-San Martin Lake (2,742 feet)

The water flows into the lake through the Mayer River and flows to the Pacific Ocean by the Pusca River.

Spanning the borders of Malawi, Mozambique (where it is known as Lago Niassa) and Tanzania (where it is known as Lake Nyasa), the sixth deepest lake in the world has a volume of 2,000 cubic miles. Lake Malawi is a meromictic lake, a lake whose layers don’t mix. The lake has a thousand cichlid species, which continue to speciate, along with many non-cichlid species. The water flows into the lake through the Ruhuhu River and discharges into the Zambezi River through the Shrine River.

Located in Kyrgyzstan, the Issyk-Kul is the second largest saline lake in the world after the Caspian Sea. The lake has a 0.6% salinity, and it is named in Krygyz after the words “warm water” as this lake never freezes even after being surrounded by snow-capped peaks of Tian Shan mountains. The lake has highly endemic fish biodiversity, with four species already being labeled as ‘seriously endangered’ due to overfishing and introduction of other fish to the lake. One of the fish introduced is the Sevan Trout, which wasn’t surviving in its native habitat at Lake Sevan in Armenia, and this fish has caused problems for the native fishes of the Issyk-Kul.

8. Lake Great Slave (2,015 feet)

This lake in Canada, having a volume of about 379 cubic miles, is also the ten largest lakes in the world. The water flows into the lake through the Mackenzie River and the main tributaries of this lake are the Hay, Slave, Lockhart, and Taltson rivers. In the 1930s, gold was discovered on the Northern Arm of the lake and this led to the establishment of the locality of Yellowknife. In 1978, a satellite Kosmos 954, feel from its orbit into the lake and disintegrated. This satellite also contained a nuclear reactor. Later, the nuclear debris was recovered by a joined operation of the Canadian and American armed forces. This lake is home to many fish, the lake trout, the northern pike, the lake whitefish and the Arctic Grayling being the most abundant.

This lake is a popular site for hiking, fishing, snowshoeing, biking, and cross-country skiing. As this lake was formed due to the collapse of the volcano Mourn Mazama, it had no life. Fish were introduced in 1,888 so that fishing could be done, and out of the six introduced species, two have survived, of which Kokanee Salmon is more plentiful than the Rainbow Trout. The lake has a pH of about 7-8, which is due to high levels of dissolved salts.
