The Ust-Ilimsk Reservoir on the Angara River, Russia58.0N 102.8E
The Angara River (Russian: Ангара́) is a 1,779 kilometers (1,105 mi) long river in Irkutsk Oblast and Krasnoyarsk Krai, south-east Siberia, Russia. It is the only river flowing out of Lake Baikal, and is a headwater of the Yenisei River.
Here, it is visible near Ust-Ilimsk, after flowing past Bratsk. It then turns west, enters the Krasnoyarsk Krai, and falls into the Yenisei near Strelka.
The Angara is dammed by the dams of three major hydroelectric plants that have been constructed since the 1950s: Irkutsk Dam, Bratsk Dam forming the Bratsk Reservoir, Ust-Ilimsk Dam forming the Ust-Ilimsk Reservoir (visible here), and Boguchany Dam (under construction) at Kodinsk.
