Kyzyl Kum
The Aydar Lake (, Айдар кўли; Haydar ko‘li, Ҳайдар кўли; alternate spellings: Lake Aydarkul, Lake Aidarkul) is part of the man-made Aydar-Arnasay system of lakes, which covers 4,000 square kilometres (1,500 mi2). This has 3 brackish water lakes (the two others being Arnasay and Tuzkan), deep basins of the south-eastern Kyzyl Kum (now in Uzbekistan and Kazakhstan). The lakes are expansive reservoirs of Soviet planning.
