Site description (2006 baseline)
The IBA is a closed salt lake at the bottom of a hollow collecting the waters of several intermittent rivulets and one major river, the Taldysai, set amid undulating fields, 2 km to the north-east of Kobensai village (Walikhanovsky district). The water level fluctuates in accordance with periodical cycles of filling, dropping sometimes to a very low point. The maximum depth is 1 m; the growth of vegetation is insignificant. The average altitude of the shoreline is 28 m above sea level. The hollow is surrounded by patches of waterlogged saline land and swampy saltpans. The agricultural edges of the hollow rise to 47-77 m. All around the lake, from 3.5-12 km, there are numerous cultivated fields, predominantly wheat, though some are abandoned. The boundaries of the IBA, covering an area of c. 22 x 35 km, includes the lake proper (c13 x 20 km at times of maximum flooding) and virgin steppe with spare vegetation typical of dry steppe and semi-desert. Along the lines of the rivulets’ beds there are a few small ponds with fresh or brackish water and poor reed growth.

Key biodiversity
Because of the saltiness of the main waterbody, the site does not support a diverse breeding avifauna, though it does have a small shorebird assemblage. The major value of the site is as an autumn passage location for significant concentrations of Demoiselle Cranes (Grus virgo), with up to 40,000 birds according to the claims of local residents. The most important and traditional area for these cranes are the western banks of the lake.
