Mongolia - May 6th, 2012

As its name would suggest, Mongolia’s Great Lakes Depression contains several large bodies of water. Visible near the top edge is Lake Uvs Nuur, which appears bright white here as its surface is frozen.

In the center of the image, south of Lake Uvs, are Lake Khyargas (above) and Lake Airag (below). The former is significantly larger than the latter. It is dark blue in color, although the eastern half is slightly greener. The smaller Lake Airag is bright green.

Continuing south, several other lakes can be observed near the bottom of the image: Lake Khar, Lake Dörgön and Lake Khar-Us (right to left). These lakes show varying shades of blue, green and brown.

Russia, Mongolia, Kazakhstan and China - October 13th, 2010

The Sayan Mountains, capped in snow, have a central position in this image. Multiple lakes can be observed in the lowlands near the foot of the range.

In the upper right quadrant, in Russia, is the Krasnoyarskoye Reservoir, appearing as a thick dark blue line. The reservoir is located along the Yenisei River.

To the south, across the mountains near the center right, is Lake Uvs Nuur. It is situated on the border between Russia’s Tuva Republic (north) and Mongolia (south). Several other lakes can be seen further south, in Mongolia’s Great Lakes Depression.

In the lower left quadrant, the lake that appears as a long, thick, jagged line is Lake Zaysan, in Kazakhstan. To the east, is the brighter green Lake Ulungur, in China’s Xinjiang Uygur Autonomous Region.

Uvs is one of the 21 aimags (provinces) of Mongolia. It is located in the west of the country, 1336 km away from the national capital Ulan Bator. Its capital is Ulaangom, which lies 936m above sea level.

Parts of the steppe in this province are protected as the World Heritage Site Uvs Nuur Basin. In the north, just out of view, the province borders the Russian Federation for 640km, in the east 340 km of border lies between Uvs and Zavkhan province. In the south and west it borders with Khovd and Bayan-Ölgii provinces for 200km each.

The province occupies 4.45% of the national territory, which is equivalent of 69,585 sq. km. Sixty percent of the total area of the province belongs to the mountainous climatic zone, and 40% to the Gobi semi-desert.

The province is named after Mongolia’s biggest lake, Uvs Nuur, touching the top edge of the image. Also visible here are the other five major lakes of Mongolia’s Great Lakes Depression: Lakes Khyargas (below Lake Uvs), Airag (smaller, just south of the former), Khar-Us (southwest of Lake Khyargas), Khar (east of the former) and Dörgön (south of Lake Khar).

Another body of water, Lake Ulungur, is visible near the center of the left edge. This lake, as well as the rest of the land in the lower left quadrant, belongs to China’s Xinjiang Uygur Autonomous Region.

Lake Uvs, Mongolia - June 8th, 2009

Lake Uvs, or Uvs Nuur, is a highly saline lake in an endorheic basin in Mongolia with a small part in Russia – its northeastern tip, situated in Russia’s Tuva Republic. All of the lake and many parts of its surroundings have been declared protected sites.

It is the largest lake in Mongolia by surface area, covering 3,350 km² at 759 m above sea level. Uvs Nuur has a length of 84 km and a width of 79 km, with an average depth of 6 m. This shallow and very saline body of water is the remainder of a huge saline sea which covered a much larger area several thousand years ago.

Its basin is separated from the rest of the Great Lakes Depression by the Khan Khökhii ridge. However, it is not a rift lake as some mistakenly think.

The main feeding rivers are the Baruntara Gol, Nariin Gol, and Tesiin Gol from the Khangai Mountains in the east, and the Kharkhiraa River and Sangil Gol from the Altai Mountains in the west. All of these can be

The very large catchment area with no exit results in highly saline water (18.8 ppt, 5 times saltier than the oceans), primarily due to sulphate and sodium ions.
