Site description A brackish lake artificially created by artesian wells situated in the lowest part of the Minbulak hollow in the Central Kyzylkum. Water levels are affected by atmospheric precipitation and show a small amount of seasonal fluctuation. However, in general, there appears to be a steady increase, both in water levels and the general area of the lake. Throughout the observation period the area of reedbeds has increased. As the lake is up to 15-20 m. deep, the borders of the reedbeds are well defined. On the shore water-tolerant shrubby and grassy vegetation is well developed. The lake is surrounded by barkhan sands. Aksay lake is located in the central part of the Kyzylkum desert, 50 km to the west of Uchkuduk city and 25 km to south-east of Minbulak settlement.

|Notes: On southern coast of lake there is a personal farm of herder. Its territory is enclosed by material at hand.|
|Notes: The artesian chink with hot water functions. In 1970-1990 the lake was a summer pleasure resort for people from Uchkuduk city, in autumn and winter â€“ for fishers and hunters. Now itâ€™s not a pleasure resort any more. Earth roads became difficult to traverse and visiting the lake by people sharply reduced. Sometimes fishers (it is introduced a lot of fish in the lake) and hunters come.|
Other biodiversity Sus scrofa was formerly numerous in the reedbeds being met in hundreds, but is now practically exterminated. Gazella subgutturosa subgutturosa regularly drink from the lake. In the coastal dunes Varanus griseus is typical. They concentrate here especially during droughts and hunt mainly on birds. In the vicinity of the lake are rare species of jerboas – Jaculus turcmenicus, Allactaga bobrinskii and Eremodipus lichtensteini. Red Data Book species are: mammals - Gazella subgutturosa; reptiles – Varanus griseus.
