The Schalkartengis ( Russian Шалкартенгиз ) is a salt lake in Kazakhstan .
The basin of the Schalkartengis, located in the extreme southeast of the Aqtöbe area , almost 200 kilometers northeast of the city of Aral in the extreme northeast of the Turan lowlands, lies at an altitude of about 50 m, is surrounded by a sandy desert in the south and is now a drainless depression.
By the end of the sixteenth century it was completely filled by the river Turgai coming from the north , so that it then flowed south to the Aral Sea . Maps from around 1900 show a lake with no outflow. After a progressive decline in the inflow, also due to increasing water extraction from the tributaries, the Schalkartengis has mostly dried up since the 1960s and had meanwhile turned into a barren salt marsh . Unusually strong floods at the beginning of the 1970s caused the depression to flood and the formation of a larger lake with numerous islands, so that - similar to Lake Tengiz - flamingos formed summer breeding colonies here.
If the Turgai has water in spring, the salt pan is transformed into an Epsom salt lake with a maximum depth of two to three meters and an area of up to 1800 km².
