If someone thinks that allotment of the territory is the destiny of political maps, he or she is mistaken. A striking example is enclosed "seas" of Remote Asia. Not a long time ago,Alakol andSasykol were a single reservoir. But from the time of their separation (which itself became an argument for the proponents of theoryof Central Asia “drying”), each of the lakes went its own way.
Sasykolis relatively small reservoir and is desalinates by the Tentek waters; it is freshwater lake. Due to the large evaporation area Alakolis salty, even a few big rivers flow into it. That is why, despite all the similarities, there is the difference in the flora and fauna of the twin lakes is felt.
On Sasykol, summer weather is not always conducive to love, there, in fresh water, are ideal conditions for mosquito breeding. "Harlequin flies" are foundin salty Alakol, they are annoying, but harmless "gnats", which do not need your blood.
Usually such characters of the living planet as Alakolharlequin fliesare only tiresome and annoying background. Meanwhile, you should look closely at them. Huge "floating" swarms of harlequin flies(they are included in the Dipterousclass and their 3000 species are closely related to ordinary mosquitoes family Chironomad) could reach up to several meters wide and hundreds of meters in length. At low level flight, when oscillations of the wings are over 594 flaps per minute, alive cloud produces a characteristic ringing, from which these harmless gnats received the name. During their short life (3-7 days) they (praise to the Creator!) do not eat, they have no mouthparts. But their larvae are the perfect food for many fishes.
However, until recently both lakes were one. Today everyone inclines to this. But Alexander Schrenk realized that first, he was here in 1840. Semenov-Tyan-Shansky also noticed that, when he walked on to swampy bridge separating Alakol and Sasykol 17 years later, at the end of his epic Tian-Shan trip (now here is a road from Usharal to Makanchi).
"My acquaintance with extensive basin of Lake Ala- kul only confirmed what was ascertained in 1840 by Alexander Schrenk,the first researcher of Semirechensk Alatau and neighboring lakes - Balkhash and Ala- kul. Basin of Lake Ala -kul consisted of two major lakes - East and West in our time (1840 - 1858). They are divided by a marshy isthmus twenty versts in width, and partly overgrown with reeds,studdedwith small lagoons that are connected by canal. At other times of the year and in some years, the isthmus is flooded with water andimpassable, so both lakes are more or less merged into one."
This brings to mind the following moments of the route description of Plano Carpini (1246):
"We drove many days along the shores of the sea, it has quite a lot of small islands, and we left it on the left side."
It is possible that the way to Karakorum passed alongthe large (Ulu - Great) lake in XIII century, which included Alakol, Sasykol, Zhalanashkol and perhaps even EbiNur. You can actually drive "many days" along such a reservoir, which stretched for more than 300 kilometers.
...Geography is alivescience. The Earth is open system, therefore it exposed to constant influences from outside and inside. Here in Alakollobe, geographical changes occur literally "in front of the eyes", and without our involvement.
