Angara

Lore & Background

The Angara, also historically called the Angar, is a major Siberian river flowing through Irkutsk Oblast and Krasnoyarsk Krai. It originates as the sole outflow of Lake Baikal, emerging near the settlement of Listvyanka, and serves as the primary headwater tributary of the Yenisey River. The river’s upper section, from its source to its confluence with the Ilim River, was once distinguished as the Lower or Nizhnyaya Angara, while the lower stretch below the Ilim was known as the Upper Tunguska. The Angara’s course runs northward past the cities of Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk, then crosses the Angara Range, turns west into Krasnoyarsk Krai, and meets the Yenisey near Strelka, southeast of Lesosibirsk. Four major hydroelectric dams—Irkutsk, Bratsk, Ust-Ilimsk, and Boguchany—have been built since the 1950s, creating large reservoirs that flooded numerous villages and agricultural lands, including the historic fort of Ilimsk. This dam construction drew criticism from Soviet intellectuals, notably writer Valentin Rasputin. The river is navigable in isolated sections, but no ship locks or lifts connect the dams, preventing through navigation from Lake Baikal to the Yenisey. Historically, the Angara and its tributary the Ilim formed crucial water routes for Russian colonization after 1630, linking the Yenisey to Lake Baikal and the Lena River, though this importance declined with the construction of overland routes and the Trans-Siberian Railway.

Since the 1950s, four major hydroelectric dams—Irkutsk, Bratsk, Ust-Ilimsk, and Boguchany—have been built on the Angara, creating large reservoirs that flooded villages, agricultural land, and historic sites such as the fort of Ilimsk. The construction drew criticism from Soviet intellectuals, notably writer Valentin Rasputin, for its impact on rural life. Today, navigation is limited to isolated sections, as none of the dams have ship locks or boat lifts, preventing through navigation from Lake Baikal to the Yenisey.

Historically, the Angara and its tributary the Ilim formed a crucial water route for Russian colonization of Siberia from around 1630, connecting the Yenisey with Lake Baikal and the Lena via portages. This route lost its importance after an overland road between Krasnoyarsk and Irkutsk and later the Trans-Siberian Railway were built. The river drains from Lake Baikal near Listvyanka, flowing north past Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk before crossing the Angara Range, turning west into Krasnoyarsk Krai, and joining the Yenisey near Strelka. Its major tributaries include the Irkut, Kitoy, Belaya, Oka, Iya, Ilim, Kova, Koda, Chadobets, Mura, Irkeneyeva, and Taseyeva. The river was formerly known as the Lower or Nizhnyaya Angara, and below its junction with the Ilim as the Upper Tunguska.

Did You Know?

• Historically, the entire river below the Ilim confluence was called the Lower Angara, and also the Upper Tunguska.
• Four major hydroelectric dams—Irkutsk, Bratsk, Ust-Ilimsk, and Boguchany—have been built on the river since the 1950s.
• None of the dams have ship locks or boat lifts, preventing continuous navigation from Lake Baikal to the Yenisey.
