Koksu River is located at the western end of the Dzhungarsky Alatau ridge, is the left tributary of the Karatal River, flows through the territory of the Kerbulak, Eskeldinsky and Koksu regions of the Almaty region.

The river is formed at an altitude of 1915 m. a. s. l. from the confluence of the Karaaryk and Kazan rivers. The catchment area of ​​the river is 4670 square kilometers. The length of the Koksu River from the confluence of the Karaaryk and Kazan rivers to the mouth of the Karatal River is 159 kilometers.
In the upper reaches, the riverbed is located at the bottom of a narrow intermountain valley, which acquires canyons at the intersections of mountain ranges. They are formed by the spurs of the Toksanbai ridge. The Koksu valley is rocky in the upper part.
The channel is moderately winding, the banks are steep, the height is 0.2 - 0.8 meters, in some places - up to 2 - 4 meters. Floodplain 5 - 10 meters wide. Food snow, glacial. High water in March - September. The depth of the river is from 0.5 to 1.5 meters.
The average annual water flow near the settlement "Koksu" is 37 meters per second. The channel is moderately winding, the banks are steep. Dzungarian Alatau consists of several parallel ranges stretching from the northeast to the southwest and separated by intermountain depressions.
The deepest of the intermountain depressions, through which the Koksu River flows, divides the Dzungarian Alatau into the northern and southern central ranges. The average annual flow of water 46 kilometers from the mouth is about 57 cubic meters per second.
The average slope of the river is 0.004 - 0.005 meters. Behind the village of Baktybay Zholbarysuly, Koksu merges with the Karatal River, which almost doubles the water flow. Passing the foothills with their hilly relief, the river enters the Karatal valley and crosses it in a direction parallel to the channel of the Karatal river to its confluence with the latter.
The catchment area in the middle part is used for settlements and crops and as a pasture, the water in the lower part of Koksu is used for water supply and irrigation. There are bridges at the intersections of the river with roads and railways.

Hydrograph of characteristic water discharges on Koksu River.

The flow of the river is formed mainly due to the melting of glaciers. That is why the maximum water levels in the river are observed in mid-July - the hottest month of summer. In the spring there is also a small flood caused by snowmelt, but, as a rule, it is much weaker than in July.
The maximum flow on the Koksu River takes place in May - July and very rarely at the end of April. The earlier highs are from snowmelt in the catchment area, while the later highs are from glacier melt. During the flood, two types are clearly traced - spring snow and summer - glacial.
n general, these peaks have separate fluctuations of flood waves. There is no summer low water. The low season falls on the month of October. This month the levels are stable. The highest standing of the water level is usually observed during the passage of a snow flood.
Koksu River is characterized by the presence of frequent mudflows - mudflows. The combination of heavy rains, especially warm ones, with spring snowmelt or glacier melt in summer can cause mudflows. Drinking water. In the middle reaches it is used for irrigation of agricultural crops and as a pasture, the water in the lower reaches of the Koksu is used for water supply and irrigation.
The Koksu River flows through the villages (from northwest to southeast): Kanaral, Karatal, Eltai, Baktybay Zholbarysuly, Balbyk bi, Zhastar, Akshatogan, Zhanalyk, Aldabergen, Enbekshikazakh, Mambet, Talapty, Yntymak, Rudnichny, Koksu.
