Ili River

geography Maturity 7-9 Next article →

The Ili River is a vital watercourse in Central Asia. It flows through northwestern China and southeastern Kazakhstan. The river begins in the Eastern Tian Shan mountains. It is formed by the Tekes and Künes rivers. This river drains the basin between the Tian Shan and the Borohoro Mountains.

It eventually flows into Lake Balkhash. This lake is part of the endorheic Balkhash-Alakol Basin. An endorheic basin is a drainage system that does not reach the ocean.

The name of the river has several possible origins. Some believe it comes from a Mongolian word meaning "open," "clear," or "obvious." This likely refers to its wide central valley. Other theories suggest Persian or Iranian roots. These terms might mean "big river" or "murky." The water can appear murky at the confluence of the Künes and Tekes rivers.

Some Uyghur scholars suggest the name means "hook." They believe the river's shape resembles a hook. Some tourist websites claim it comes from the Mongolian word "ilansu," meaning "shimmering" or "sparkling."

History shows that the Ili River has long been a significant landmark. The river was mentioned in the year 1072. This was in the Dīwānu l-Luġat al-Turk, a dictionary by Mahmud al-Kashgari. He noted that Turkic tribes lived along its banks. Even earlier, in 638 AD, a treaty used the river as a border. This treaty divided the Western Turkic Kaganate into the Nushibi and the Dulu states.

In the late 18th and 19th centuries, the region was a stronghold for the Qing administration. Russia occupied the area from 1871 to 1881. Today, the region includes the Ili Kazakh Autonomous Prefecture in Xinjiang. The main city, Yining, sits on the northern side of the river.

The river provides immense power and water for the region. Many dams have been built on its various tributaries. For example, there are dams on the Kash River in Nilka County. The Tekes River also has at least two dams. The Qiapuqihai Hydropower Station is located in Tokkuztara County.

Between 1965 and 1970, engineers built the Kapchagay Hydroelectric Power Plant. This plant created the Kapchagay Reservoir. This reservoir is a long, artificial lake located north of Almaty. In terms of water content, the Ili is the third largest river in Kazakhstan. It follows only the Irtysh and the Ural rivers.

Where the Ili meets Lake Balkhash, it creates a massive delta. This delta covers an area of about 45,000 hectares. It sits between the Saryesik-Atyrau Desert and the Taukum Desert. The delta is a vast wetland with many lakes, marshes, and plants.

It is a designated Ramsar Site, which is a wetland of international importance. The area supports 427 species of plants and 345 species of animals. You might see rare species like the Dalmatian pelican or the white-headed duck. The water is also home to the wels catfish. These large predators can grow to over 3 meters in length.

The delta is also a site of great interest for wildlife conservation. Until 1948, the Caspian tiger lived in this delta. Because the Caspian tiger is extinct, experts have proposed introducing the Siberian tiger. The Siberian tiger is a genetically close relative. The delta has a large population of wild boar, which is the main prey for the tiger. There are also roe deer in the area. Scientists are also considering reintroducing the Bactrian deer and the Asiatic wild ass.

Today, the Ili River faces modern challenges. As water needs increase in both China and Kazakhstan, management becomes difficult. Environmentalists and politicians must work together to manage this cross-border river. They must ensure that Kazakhstan receives enough water flow from China. The river remains a complex system of biology, history, and human necessity.
