[2] On the border with the mountain ranges formed depression, in which there was an accumulation of wastewater flowing into rivers, creating isolated water bodies.

Along the wetlands there is a lot of salty clay with rotted lake vegetation, which is actively used for balneological purposes by the local population and tourists.

The sloping banks are gravelly and pebbly, in the Eastern part of the coast is steep, in the southern-swampy, with a wide strip of submerged reeds.

(The Terekty River flows toward Zhalanashkol from the mountains of China's Yumin County, but reaches the lake only in the form of a usually dry alluvial fan.)

The lake is fed by ground water, and by seasonal runoff of rainwater or snow meltwater from the surrounding area.
