Angara

geography Maturity 7-9 Next article →

The Angara is a major river located in Siberia. It flows through two Russian regions known as Irkutsk Oblast and Krasnoyarsk Krai.

The river serves as the primary outlet for Lake Baikal. It acts as the headwater tributary for the much larger Yenisey River. This means the Angara provides a significant portion of the water that feeds into the Yenisey system. Historically, the river had different names depending on its location. It was once called the Lower or Nizhnyaya Angara to distinguish it from the Upper Angara. Below its junction with the Ilim River, it was known as the Upper Tunguska.

The river follows a specific path through the Siberian landscape. It begins its journey leaving Lake Baikal near the settlement of Listvyanka. From there, the water flows north past several major cities. These include Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk.

After passing these urban areas, the river crosses the Angara Range. At this point, the river turns toward the west. It enters the Krasnoyarsk Krai region before finally joining the Yenisey near Strelka. This location is situated southeast of Lesosibirsk.

Since the 1950s, humans have significantly altered the river's natural flow. Engineers constructed four major hydroelectric plants to exploit the river's power. These plants use the movement of water to generate electricity. The first is the Irkutsk Dam, which created the Irkutsk Reservoir. This reservoir floods the river valley from its source all the way to Irkutsk. It also slightly raises the water level of Lake Baikal.

The second is the Bratsk Dam, which formed the Bratsk Reservoir.

Two more dams continue this pattern of changing the landscape. The Ust-Ilimsk Dam was built at Ust-Ilimsk to create the Ust-Ilimsk Reservoir. Finally, the Boguchany Dam was constructed at Kodinsk. These massive projects had a profound impact on the local environment and people. The creation of these reservoirs flooded many agricultural areas in the river valley. They also submerged numerous villages that were once home to rural residents.

Even the historic fort of Ilimsk was lost beneath the rising waters.

These changes caused significant social and cultural concern in Russia. Many Soviet intellectuals criticized the construction of these large dams. The writer Valentin Rasputin was a notable critic of these projects. He wrote about the impact on rural life in his 1976 novel, *Farewell to Matyora*. He also addressed these issues in his 1991 non-fiction book, *Siberia, Siberia*. His work highlighted how the changing river affected the way of life for local people.

Navigation on the Angara has also changed due to these structures. The river is currently navigable by modern watercraft only on isolated sections. Boats can travel from Lake Baikal to Irkutsk. They can also move from Irkutsk to Bratsk using the Ust-Ilimsk Reservoir. Another navigable section exists from the Boguchany Dam to the river's junction with the Yenisey. However, the section between the Ust-Ilimsk Dam and the Boguchany Dam remains unnavigable due to rapids.

Even with the completion of the Boguchany Dam, continuous travel is not possible. None of the existing three dams feature a ship lock or a boat lift.

Historically, the Angara played a vital role in the colonization of Siberia. Starting around 1630, the river and its tributary, the Ilim, were essential water routes. They connected the Yenisey River with Lake Baikal and the Lena River. This connectivity was possible through the use of necessary portages. The river eventually lost its importance as a transport route. This happened because of the construction of overland routes between Krasnoyarsk and Irkutsk. Later, the development of the Trans-Siberian Railway changed transportation in the region forever.

The Angara is fed by many different tributaries. These rivers flow into the main channel at various points. The largest tributaries, listed from the source to the mouth, include the Irkut, Kitoy, Belaya, and Oka. Other significant contributors are the Iya, Ilim, Kova, Koda, and Chadobets. The river also receives water from the Mura, Irkeneyeva, and Taseyeva rivers. This complex network of smaller rivers helps sustain the massive drainage basin of the Angara.
