Issyk-Kul

Issyk-Kul is a huge, deep lake high in the Tian Shan mountains of Kyrgyzstan, fed by more than a hundred rivers and streams. Its name means 'hot lake', because even in cold winters it hardly ever freezes.

The story behind it

Issyk-Kul lies 1 607 metres above the sea and is very deep: up to 668 metres. After Lake Titicaca, it is the second-largest mountain lake in the world. About 118 rivers and streams flow into it, but no river flows out. That is why its water is slightly salty, although much less salty than the sea. The salt is one reason the lake hardly ever freezes, even when the winter air is icy cold. Under the water, researchers have found remains of old settlements. One of them, Toru-Aygyr, was founded in the 13th century and sank beneath the waves after earthquakes in the 15th century. In Soviet times, many holiday homes were built along the northern shore, and the lake became a popular place for holidays. Towns on the shore include Karakol, Cholpon-Ata and Balykchy. Issyk-Kul is by far the largest lake in Kyrgyzstan.

Questions children ask

How big is Issyk-Kul?

Issyk-Kul covers about 6 236 km² and is about 178 km long and up to 60 km wide. At up to 668 metres, it is also one of the deepest lakes in the world.

Why does Issyk-Kul hardly ever freeze?

Its water is slightly salty, and salty water freezes less easily than fresh water. So even when the winter air is very cold, the lake usually stays open.

Is Issyk-Kul the largest lake in Kyrgyzstan?

Yes, by far. The second-largest lake in the country, Song-Köl, covers only about 270 km².
