Geography

The main rivers in the district include the Yana, the Omoloy with the Ulakhan-Kyuegyulyur, the Sellyakh, as well as the Chondon with its tributary the Nuchcha. The Kyundyulyun, northernmost spur of the Chersky Range, rises north of Ust-Kuyga. There are numerous lakes in the district. Orotko is one of the largest.[12][13][14]

Average January temperature ranges from −32 to −40 °C (−26 to −40 °F) and average July temperature ranges from +4 to +12 °C (39 to 54 °F).[2] Annual precipitation ranges from 150–200 millimeters (5.9–7.9 in) in the north to 250–300 millimeters (9.8–11.8 in) in the south.[2]

History

The district was established on January 5, 1967.[2]

Demographics

As of the 1989 Census, the district had a population of 41,265 inhabitants, with an ethnic composition as follows:[2]

• Russians: 58.7%
• Yakuts: 8.7%
• Evens: 2.2%
• Evenks: 0.1%
• other ethnicities: 30.3%

However, a great deal of the ethnic Russian population left with the economic downturn following the collapse of the Soviet Union, so much so that the district lost over three-quarters of its population during the 1990s.

In the 2010 census, the indigenous Yakuts again formed a majority of inhabitants, with the total population now just 8,262. In that year, the ethnic composition of the district was:

• Yakuts: 43.1%
• Russians: 27.2%
• Evens: 16.7%
• Ukrainians: 5.7%
• Yukaghirs: 1.2%
• other ethnicities: 6.1%

Economy

The main industries are gold mining, reindeer herding, fishing, and fur trade. There are deposits of gold, tin, tungsten, mercury, lead, zinc, and brown coal.[2]
