context_page_description: The Kolyma is a river in northeastern Siberia, whose basin covers parts of the Sakha Republic, Chukotka Autonomous Okrug, and Magadan Oblast of Russia.
  The Kolyma is frozen to depths of several metres for about 250 days each year, becoming free of ice only in early June, until October.
context_section_description: There is a hydropower plant at Sinegorye (Kolyma Hydroelectric Station)
  in the upper part of the river. The plant was started in the 1980s by Kolyma Gestroi and both the plant and the town of Sinegoria were built under the supervision of chief engineer Oleg Kogadovski. The town included an olympic sized swimming pool, an underground rifle range, and many amenities absent in most other small Russian towns. Kogadovski said that in order to attract and employ good talent in such a remote place, the town had to be exceptional. The dam provides most of the electricity to the region including Magadan. the Kolyma dam is an earthen dam some 150 ft high. Air circulation tubes carry frigid winter air into the core of the dam where frozen earth stabilizes the structure. Kolyma Ges. said it was the largest dam ever built in a permafrost region. A new hydropower plant is under construction at Ust-Srednekan (Ust-Srednekan hydropower plant). Larch forests cleared for the reservoir were cut in winter when the trunks are frozen and easily snapped. The wood was sold for pulp.
  There are only a few bridges over the river, including at Ust-Srednekan, at Sinegorye and at Debin (which carries the Kolyma Highway).
