Issyk-Kul(Russian:Иссык-Куль) orYsyk-Köl(Kyrgyz:Ысык-Көл,[ɯsɯkkœl],"Warm Lake" ) is anendorheic(i.e., without outflow)saline lakein the westernTianshan Mountainsin easternKyrgyzstan,just south of adividing rangeseparating Kyrgyzstan fromKazakhstan.It is theeighth-deepest lake in the world,theeleventh-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. Issyk-Kul means "warm lake" in theKyrgyz language;although it is located at a lofty elevation of 1,607 metres (5,272 ft) and subject to severe cold during winter, it rarely freezes over due to highsalinity.[5][6]
The lake is aRamsarsite of globally significantbiodiversity[7]and forms part of the Issyk-Kul Biosphere Reserve.
Geography[edit]
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 the second-largest mountain lake in the world behindLake TiticacainSouth America.It is at an altitude of 1,607 metres (5,272 ft) and reaches 668 metres (2,192 ft) in depth.[8]
About 118rivers and streams flow into the lake;the largest are theJyrgalangandTüp.It is fed by springs, including manyhot springsand snow melt. The lake has no current outlet, but some hydrologists hypothesize[9]that the lake's water filters deep underground into theChu River.The bottom of the lake contains the mineralmonohydrocalcite:one of the few knownlacustrinedeposits.[10]
The lake's southern shore is dominated by the ruggedly beautifulTeskey Ala-Too Rangeof theTian Shanmountains. 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. TheKungey Alatauof theTian Shanruns 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.[11]
The lake water'ssalinityis approx. 0.6% – compared to 3.5% salinity of typicalseawater– 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 centimetres (2.0 in) per year due to water diversion.[12]
Administratively, the lake and the adjacent land are withinIssyk-Kul Regionof Kyrgyzstan.
Tourism[edit]
During theSovietera, the lake became a popular vacation resort, with numeroussanitoria,boarding houses and vacation homes along its northern shore, many concentrated in and around the town ofCholpon-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.[citation needed]
The city ofKarakol(formerly Przhevalsk, after the Russian explorerPrzhevalsky,who died there) is the administrative seat ofIssyk-Kul Regionof 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 woodenmosque,built without metal nails by theDungan peopleand a woodenOrthodoxchurch that was used as a stable during Soviet times.[citation needed]
History[edit]
Issyk-Kul Lake was a stopover on theSilk Road,a land route for travelers from the Far East to Europe. The great Chinese Buddhist scholar-monkXuanzangpassed by this lake and noted the details in the classictravelogueGreat Tang Records on the Western Regionsin the 7th century. The lake was once a part of the territory ofQing Dynastyof China and was ceded to Russia – along with the surrounding territory – after theTreaty of Tarbagatai.[citation needed]
Many historians believe that the lake was the point of origin for theBlack Deaththat plagued Europe and Asia during the early and mid-14th century.[13]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.[14]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.[15]The lake's status as a byway for travelers allowed the plague to spread across these continents via medieval merchants who unknowingly carried infestedverminalong with them.
The lake level is some 8 metres (26 ft) 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 bronzecauldronwith a level of craftsmanship that is today achieved by using aninert gasenvironment.[16][17]
In 1916 the monastery at Issyk-Kul was attacked by Kyrgyz rebels, and seven monks were killed.[18]
Environment[edit]
Specially protected areas[edit]
The first nature reserve in Kyrgyzstan, Issyk-Kul State Reserve was established in 1948 to protect unique nature landscapes andwaterfowlat Issyk-Kul. In 1975, it was acknowledged as aRamsar site.Biosphere Reserve Issyk-Kul covered byUNESCOWorld Network of Biosphere Reserveswas established in year 2000 within the administrative borders ofIssyk-Kul Region.[19]
Fish[edit]
The lake contains highlyendemicfish biodiversity, and some of the species, including four endemics, are seriously endangered. In recent yearsyieldsof all fish species have declined markedly, due to a combination ofoverfishing,heavy predation by two of theintroducedinvasive species(thepike perchand therainbow trout), and the cessation of lakerestockingwithjuvenile fishfromhatcheries.At least four commercially targeted endemic fish species are sufficiently threatened to be included in the Red Book of the Kyrgyz Republic —Schmidt's dace(Leuciscus schmidti),Issyk-Kul dace(Leuciscus bergi),Ili marinka(Schizothorax pseudoaksaiensis issykkulensis), and sheer or naked osman (Gymnodiptychus dybowskii). Five other indigenous species —Issyk-kul minnow(Phoxinus issykkulensis),Issykul gudgeon(Gobio gobio latus),spotted thicklip loach(Triplophysa strauchii ulachilicus),grey stone loach(Triplophysa dorsalis),asp(Leuciscus aspius iblioides) — are almost certainly threatened asbycatchor are indirectly impacted by fishing activity and changes to the ecological structure and balance of the lake's fish population.
Sevan trout,a fish endemic toLake SevaninArmenia,was introduced into Issyk-Kul in the 1970s. While this fish is anendangered speciesin its native waters, it has a much better chance to survive in Lake Issyk-Kul where it has actively predated on other species, but is limited in habitat for reproduction and in food.[20]
Dead Lake[edit]
There is a small lake below the water level of Issyk Kul at the south west side of the lake. This lake is called Tyz köl (salt lake) in Kyrgyz due to its very high saline content and swimming in the Issyk Kul salt lake is a very different experience from less salty water. The lake receives its water from small cold springs at the beach which lead the cold, less heavy water to the top of the lake and often the salty, heavy water below is oddly more warm than the water on the surface.[21]
[edit]
During theSoviet period,theSoviet Navyoperated an extensive facility at the lake's east end, where submarine and torpedo technology was evaluated.[22]In March 2008, Kyrgyz newspapers reported that 866 hectares (2,140 acres) around theKarabulan Peninsulaon the lake would be leased for an indefinite period to theRussian Navy,which is planning to establish new naval testing facilities as part of the 2007 bilateral Agreement on Friendship, Cooperation, Mutual Help, and Protection of Secret Materials. The Russian military will pay $4.5 million annually to lease the area.[23]Indiaalso plans to invest in the facility to test all types of torpedoes such as heavy weight torpedoes and those that have thermal navigation system. Another advantage that works for the testing center is that the torpedoes fired can also be recovered allowing scientists to make physical verification of a torpedo structure for further study. India is also planning to use the torpedo test facility to test theautonomous underwater vehiclebeing developed byNSTL.For this, India has proposed to engage local companies with know-how in torpedo technology to further co-develop the facility.[24]
