Wildfire West of Krasnoyarsk Reservoir, Russia

Mongolia and Russia – May 31st, 2012

Many bodies of water can be observed in this image. In the upper part is the Krasnoyarsk Reservoir, created by the dam of the same name on the Yenisey River, in Russia. The Krasnoyarsk dam has greatly affected the local climate. Before the dam was built, the Yenisey in that area was free from ice around 196 days per year. Now it is free from ice the entire year up to 300 to 400 km downstream. The huge amount of water stored in Krasnoyarskoye reservoir makes the local climate more warm and humid.

Also of interest near the reservoir, to its west, is a wildfire (best observed at the top left of the full image). Smoke from the fire is blowing in a straight line towards the southwest.

Visible in the lower half of the image are several lakes in Mongolia: the rounded Lake Uvs Nuur, Lake Khyargas (below the former), Lake Airag (the small green lake just below Lake Khyargas), and, near the bottom edge from right to left, Lakes Khar, Dörgön and Khar-Us.

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.

Several lakes can be observed in Mongolia’s Uvs province, located in the west of the country. The province has both mountainous and Gobi semi-desert climatic zones, although this image focuses on the latter.

The five lakes visible here belong to the country’s Great Lakes Depression. The northernmost is Lake Khyargas, dark greenish blue with an elongated shape and irregular edges. Smaller, greener in color and just to its south is Lake Airag. Due south of those two are Lake Khar (green) and Lake Dörgön (further south, dark blue). Finally, the irregularly shaped Lake Khar-Us, showing various shades of green, is located west of the aforementioned pair.

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.

The lakes visible here in the Khyargas District of Mongolia’s Uvs Province are part of the same system interconnected lakes in the Great Lakes Depression.

The large, dark greenish blue lake at the top is Lake Khyargas, upon which the Khyargas Nuur National Park is based.  This protected area was established in 2000 and covers about 3,328 km². It also includes the smaller, lighter green, freshwater Lake Airag, just south of Lake Khyargas.

In the lower left quadrant is Lake Khar-Us. Its area value of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head) with an area of 274 km², so the water surface area is 1,578 km² only. Here, the island appears to almost separate the bright green western side of the lake from the brown right side. Primary inflow is the Khovd Gol river, which creates a large fan-shaped river delta on the western shores.

Finally, in the lower right quadrant are Lakes Khar and Dörgön. The waters of Lake Khar, above, appear green, while those of Lake Dörgön, below, appear dark blue.
