The IBA comprises the system of lakes Soltandag-Kyzylburun-Tajlak formed on the right bank of the middle course of the Amudarya river as a result of flooding of the collector-drainage waters to the solonchak depression, arriving from the Karshinsky agricultural area of Uzbekistan from the Mehedjan collector channel. The lakes are inter-connected by spillway adjustable channels. The IBA is located between the river Amudarya and the border with Uzbekistan. The northern and eastern shore of Soltandag-Kyzylburun-Tajlak lakes is steep bank, the southern and western sloping.
The avifauna of the IBA includes 300 species, of which more than 100 are waterfowl and waterbirds. The majority of them occur during spring-autumn migration and in winter.
