In Siberia similar artificial lakes are located on the upper Yenisey and its tributary the Angara, where the Bratsk Reservoir is among the world's largest.

Some 395 miles (636 km) long and with an average width of 30 miles (50 km), Baikal has a surface area of 12,200 square miles (31,500 square km) and a maximum depth of roughly 5,315 feet (1,620 metres).
