The Krasnoyarsk Dam is a high concrete
gravity dam A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. ...
located on the Yenisey River about upstream from Krasnoyarsk in Divnogorsk, Russia. It was constructed from 1956 to 1972, and it supplies about 6,000 MW of electricity, mostly used to supply the KrAZ (Krasnoyarsky Aluminievyy Zavod, the Krasnoyarsk Aluminum Plant). Both power and aluminum plants are controlled by the RUSAL company. Beginning with the opening of the 10th turbine in April 1971, the powerhouse was the world's single largest power plant until the Grand Coulee Dam in Washington state reached 6,181 MW in 1983. The Krasnoyarsk Dam is held to be a landmark symbol of Krasnoyarsk, and it is depicted on the 10-ruble banknote. As a result of the damming, the Krasnoyarsk Reservoir was created. This reservoir, informally known as the Krasnoyarsk Sea, has an area of and a volume of . It is in length and in width at its widest, has an average depth of , and a depth of near the dam. The Krasnoyarsk Dam significantly influences the local climate; normally the river would freeze over in the bitterly cold

Ship lift

The dam is equipped with a canal inclined plane to allow passage of ships. It is in fact an electric rack railway. The track gauge is , making it the widest-gauge railway of any type in the world. At the time of its construction, this feat of modern engineering allowed for ships to be physically moved in only 90 minutes.
