Dead Lake
There is a small lake below the water level of Issyk Kul at the south west side of the lake. This lake is called the dead lake (also Tyz köl in Kyrgyz) due to its very high saline content and swimming in the Issyk Kul dead 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.
Creation legend
In pre-Islamic legend, the king of the Ossounes had donkey's ears. He would hide them, and had his barbers killed to hide his secret. One barber yelled the secret into a well, but he did not cover the well afterwards. As a result, the well water rose and flooded the kingdom. The kingdom is today under the waters of Issyk-Kul. According to the legend, this is how the lake was formed. Other legends say that four drowned cities lie at the bottom of the lake. Archaeological finds indicating the presence of man-made structures have been made in shallow waters of the lake.
