The Sarygamysh Lake ( Turkmen Sarygamyş Koeli , uzbek. Sariqamish ko'li , russ Сарыкамышское озеро -. Sarykamyschskoje Ozero ) is a slightly salty, in its present form anthropogenic arising lake, which in Central Asia the southwest Aral Sea on the border between Uzbekistan and Turkmenistan is located. The name is derived from “Sarı” (yellow) and “qamış” ( reed ).

The east of the Ustyurt Plateau located Sarykamysch Valley , the lowest point about 40 meters below sea level is located, was filled in earlier times always periodically with water when the Amu Darya changing its course entirely or with one arm in her direction, as in 7th century BC BC to the 16th century AD, when the water level was at times 50 to 62 m above sea level. Reached NN. Until about the middle of the 1st millennium BC BC the depression with the Usboi also had a drain to the Caspian Sea . In the summer of 1878 the water of the Amu Darya reached the valley for the last time naturally. After that, only several small (less than 100 km 2 ) very salty lakes remained in the central part of the depression .

As a result of the strong expansion of the artificial irrigation of the Amur Darya Valley in the times of the Soviet Union to increase the cultivation of cotton and the associated structural measures, Amu Darya water broke through again in 1971 through the old arm Darjalyk (Дарьялык) into the Sarykamysh depression, which is not was prevented.

In contrast to the rapidly shrinking Aral Sea, the lake has grown continuously since then and now has an area of ​​over 5,000 km 2 . The water level is over 5 m above sea level. NN.

The lake is largely fed by agricultural wastewater , which contains pesticides and herbicides in particular . The fish found in the lake are carp , catfish and snakehead fish . Despite the ecological problem, the lake is used for fishing.
