'''Kapchagay Reservoir''', also spelled '''Qapshaghay Bogeni Reservoir''' and sometimes referred to as '''Lake Kapchagay''', is a major reservoir in [[Almaty Region]] in southeastern [[Kazakhstan]], approximately 60 kilometres north of [[Almaty]]. The 140 kilometre long lake is formed by a dam on the [[Ili River]] which flows from the mountains in the east towards [[Lake Balkhash]] to the northwest. It is named after the town of [[Kapchagay]], which is located on its western bank. During the summer months the lake attracts a number of tourists from [[Almaty]], who frequent its beachy shores on the weekends.

The Kapchagay dam was completed in late 1969 and began slowly filling the reservoir in 1970, over a period of 20 years.<ref name="Hist">{{cite web|url=http://www.history.com/topics/lake-balkhash|title=Lake Balkhash|publisher=History.com|accessdate=May 10, 2010}}</ref><ref name="FAO">{{cite book|author1=Petr.

However, environmentalists have expressed deep concerns about its environmental impact upon Lake Balkash, given that the equilibrium and balance of water has been seriously disturbed.<ref name="FAO"/> Between 1970 and 1985, the volume of Lake Balkash declined by 39 km<sup>3</sup> to directly feed the Kapchagay Reservoir, and by 1987, Lake Balkash had reached its all-time low point in volume, dropping roughly 7 feet (2.2 metres) in depth.<ref name="Hist"/><ref name="FAO"/> However, in 1988, this situation improved when the volume of Balkash increased once more from river discharge from the east, although the water quality had been dramatically reduced and became increasingly [[Saline water|saline]].<ref name="Hist"/><ref name="FAO"/><ref>{{cite web|url=http://www.britannica.com/facts/5/189932/water-pollution-as-discussed-in-Lake-Balkhash-lake-Kazakhstan|title=Facts about water pollution: Lake Balkhash, as discussed in Lake Balkhash (lake, Kazakhstan)|publisher=[[Encyclopædia Britannica]]|accessdate=May 10, 2010}}</ref>

===Fishing and agriculture===
The reservoir has had a major impact upon fish populations, especially given that commercial fishing operations have been practiced in the reservoir, fuelling the local economy. In 1975, 24 species of fish were recorded in Kapchagay Reservoir, but in 1980 this had fallen to 18, directly affecting the industry.<ref name="FAO"/> However, between 1985 and 1991 as the river reached its current capacity, fish stocks in the lake stabilised and since 1980 there has been a marked growth in the fishing industry on the lake after its decline in the 1970s.<ref name="FAO"/> The reservoir has also been responsible for rising groundwater levels which has made it impossible to grow crops on land adjacent to the lake in many parts.<ref name="FAO"/> As a result, many agricultural villages in the area such as [[Akozek]], [[Kerbulak]] and [[Chengildi]] are located several kilometres from the lake, rather than on its bank.
