The Angara is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is 1,849 kilometres (1,149 mi) long, and has a drainage basin of 1,039,000 square kilometres (401,000 sq mi). It was formerly known as the Lower or Nizhnyaya Angara. Below its junction with the Ilim, it was formerly known as the Upper Tunguska and, with the names reversed, as the Lower Tunguska.
