Issyk Kul

Issyk-Kul () or Ysyk-Köl (, ; ) is an endorheic saline lake in the western Tianshan Mountains in eastern Kyrgyzstan, just south of a dividing range separating Kyrgyzstan from Kazakhstan. It is the eighth-deepest lake in the world, the eleventh-largest lake in the world by volume (though not in surface area), the deepest lake whose deepest point is above sea level (939 meters or 3,080 feet), and the third-largest saline lake. Although it is located at a lofty elevation of and subject to severe cold during winter, it rarely freezes over due to high salinity, hence its name, which in the Kyrgyz language means "warm lake".

The lake is a Ramsar site of globally significant biodiversity and forms part of the Issyk-Kul Biosphere Reserve.

Geography

Issyk-Kul Lake is long, up to wide and its surface area is . It is the second-largest mountain lake in the world behind Lake Titicaca in South America. It is at an altitude of and reaches in depth.

About 118 rivers and streams flow into the lake; the largest are the Jyrgalang and Tüp. It is fed by springs, including many hot springs and snow melt. The lake has no current outlet, but some hydrologists hypothesize that the lake's water filters deep underground 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 northern slopes of the range are long and send a considerable flow to Issyk-Kul. Numerous streams taking their rise at the slopes flow together into comparatively large rivers. They deeply dissect the range and flow in wide valleys. On exit from mountains the rivers form large alluvial cones. In eastern part of Issyk-Kul they flow into Jyrgalang river.
The Kungey Alatau of the Tian Shan runs parallel to the north shore. The southern slopes of the Kungey Alatau are comparatively short. Therefore, the rivers rising on them are relatively small and do not have a chance to flow together to form larger hydrographic systems. As a result, they separately empty either into Issyk-Kul or into Tüp river flowing along the range.

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 per year due to water diversion.

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

Tourism

During the Soviet era, the lake became a popular vacation resort, with numerous sanitoria, boarding houses and vacation homes along its northern shore, many concentrated in and around the town of Cholpon-Ata. These fell on hard times after the break-up of the USSR, but now hotel complexes are being refurbished and simple private bed-and-breakfast rentals are being established for a new generation of health and leisure visitors.

The city of Karakol (formerly Przhevalsk, after the Russian explorer Przhevalsky, who died there) is the administrative seat of Issyk-Kul Region of Kyrgyzstan. It is near the east tip of the lake and is a good base for excursions into the surrounding area. Its small old core contains an impressive wooden mosque, built without metal nails by the Dungan people and a wooden Orthodox church that was used as a stable during Soviet times.

History

Issyk-Kul Lake was a stopover on the Silk Road, a land route for travelers from the Far East to Europe. The great Chinese Buddhist scholar-monk Xuanzang passed by this lake and noted the details in the classic travelogue '' Great Tang Records on the Western Regions'' in the 7th century. The lake was once a part of the territory of Qing dynasty of China and was ceded to Russia – along with the surrounding territory – after the Treaty of Tarbagatai.

Many historians believe that the lake was the point of origin for the Black Death that plagued Europe and Asia during the early and mid-14th century. In 2022, researchers reported on the analysis of preserved genetic material from seven individuals buried in two cemeteries near Issyk-Kul and determined that the Black Death was present there in 1338 or 1339. The plague first infected people in a small, nearby settlement of traders eight years before it devastated Eurasia, killing 60 percent of the population, having traveled along trade routes. The lake's status as a byway for travelers allowed the plague to spread across these continents via medieval merchants who unknowingly carried infested vermin along with them.

The lake level is some higher than in medieval times. Divers have found the remains of submerged settlements in shallow areas around the lake.

Articles identified as the world's oldest extant coins were found underwater, with gold wire rings used as small change and a large hexahedral goldpiece. Also found was a bronze cauldron with a level of craftsmanship that is today achieved by using an inert gas environment.

In 1916 the monastery at Issyk-Kul was attacked by Kyrgyz rebels, and seven monks were killed.

Environment

Specially protected areas

The first nature reserve in Kyrgyzstan, Issyk-Kul State Reserve was established in 1948 to protect unique nature landscapes and waterfowl at Issyk-Kul. In 1975, it was acknowledged as a Ramsar site
