The Irkutsk reservoir ( Russian Иркутское водохранилище / Irkutskoje wodochranilishche ) near Irkutsk in the Russian Irkutsk Oblast ( Siberia ; Asia ) is a reservoir on the Angara .

Geographical location

The Irkutsk reservoir is located a little northwest of the southwest end of Lake Baikal , just below the outflow of the Angara from this lake . The south-westerly foothills of the Baikal Mountains stretch north-east of the reservoir, while the eastern foothills of the Eastern Sayan rise to the west . Its shut-off structure and power plant are located on the south-eastern edge of the urban area of Irkutsk .

Dam, reservoir and power plant

The barrier structure consists of a 44 m high earth embankment combined with an integrated gravity dam . The hydropower plant integrated into the wall , which was part of the planned development of the Angara - Yenisei region, was built from 1950 to 1959 and has an output of 660  MW .

Due to the approximately 2.5 km long dam of the Irkutsk reservoir, which has a storage volume of around 4.6 billion  m³ , the Angara accumulates a maximum height of around 28 m and the river backs up almost 60 km to just before Lake Baikal - without this To influence the water level. According to other sources, Lake Baikal is dammed by 1.4 m or even 6 m by the dam. The storage volume including the additionally dammed Lake Baikal amounts to 45.8 billion m³.
