The northern and western parts of the reservoir are deep (maximum depth is not more than 20 m), the southern shore is gently sloping and not more than 2 m deep. Inflow comes from the Karakum channel, usually from the beginning of September. Water is lost in July. The water level fluctuates between seasons and years.
