Gusinoozersk (Russian: Гусиноозёрск; Buriat: Галуута Нуур, Galuuta Nuur; Mongolian: Галуутнуур, Galuutnuur) is a town and the administrative center of Selenginsky District of the Republic of Buryatia, Russia. Population: 13,800 (1970). It was previously known as Shakhty (until 1953).
The town is located in the area of the Selenga Highlands, on the northeastern shore of Lake Gusinoye, 110km (70miles) southwest of Ulan-Ude.
It was founded in 1939 under the name Shakhty (Russian: Ша́хты),[1] in connection with the commencement of exploitation of brown coal deposits in the area. In 1953, it was granted town status and given its present name, derived from Gusinoye Ozero (lit. "goose lake"), the Russian name for the lake on which the town stands.
Within the framework of administrative divisions, Gusinoozersk serves as the administrative center of Selenginsky District.[2] As an administrative division, it is, together with two rural localities, incorporated within Selenginsky District as the Town of Gusinoozersk. As a municipal division, the Town of Gusinoozyorsk is incorporated within Selenginsky Municipal District as Gusinoozersk Urban Settlement.[3]
The main focus of the town's economy remains brown coal production and the associated power station, although mining activities on the nearby deposits slowed during the economic crisis of the 1990s.
Zagustay railway station on the Trans-Mongolian Railway is located 5km (03miles) east of the town.
The 245th Motor Rifle Division of the Russian Ground Forces was located in the town until it was reduced to a Base for Storage of Weapons and Equipment in 2006.
