Issyk-Kul

Issyk-Kul is an endorheic lake in the northern Tian Shan mountains in eastern Kyrgyzstan. It is the tenth largest lake in the world by volume (though not in surface area), and the second largest saline lake after the Caspian Sea. Issyk-Kul means "warm lake" in the Kyrgyz language; although it is surrounded by snow-capped peaks, it never freezes.

Issyk-Kul Lake is 182 kilometres (113 mi) long, up to 60 kilometres (37 mi) wide, and its area is 6,236 square kilometres (2,408 sq mi). It is second largest mountain lake in the world behind Lake Titicaca in South America. It is at an altitude of 1,607 metres (5,272 ft), and reaches 668 metres (2,192 ft) in depth.

About 118 rivers and streams flow into the lake; the largest are the Djyrgalan and Tyup. It is fed by springs, including many hot springs, and snow melt. The lake has no current outlet, but some hydrologists hypothesize that, deep underground, lake water filters into the Chu River. The bottom of the lake contains the mineral monohydrocalcite: one of the few known lacustrine deposits.

The lake's southern shore is dominated by the ruggedly beautiful Teskey Ala-Too Range of the Tian Shan mountains. The Kungey Alatau of the Tian Shan runs parallel to the north shore.

The lake water's salinity is approx. 0.6% compared to 3.5% salinity of typical seawater and, although the lake level is still currently some 8 metres (26 ft) higher than in medieval times, its level now drops by approximately 5 cm per year due to water diversion.

Administratively, the lake and the adjacent land are within Issyk-Kul Region of Kyrgyzstan.
