Bratsk Reservoir (Russian: Братское водохранилище, romanized: Bratskoye vodokhranilishche) is a reservoir on the Angara River, located in the Lena-Angara Plateau of Irkutsk Oblast,[1] Russia.

The Baikal Amur Mainline railroad runs along the top of the dam.

[2] To this day, it is classified as the second biggest dam in the world by reservoir storage capacity.

[4] The epic construction of the Bratsk Dam is the subject of a long eponymous poem by Yevgeny Yevtushenko.

Much later (1976), the impact of the reservoir construction on the life of the villagers upstream, many of whom had to be relocated from the flooded areas, or lost some the best lands of their collective farms, became the motive of Valentin Rasputin's novel Farewell to Matyora.
