The Aydar Lake (Uzbek: Aydar Ko‘li, 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.

Being brackish rather than saline they have high rates of evaporation, prompting a moist summer microclimate, often attracting rain clouds, which has led to the replenishment of the North Aral Sea.
