Caspian Sea - July 26th, 2011

The Caucasus Mountains stretch between the Black Sea (left) and the Caspian Sea (right) in the Caucasus region of Eurasia. The Caucasus Mountains include the Greater Caucasus Mountain Range and
the Lesser Caucasus Mountains.

The Greater Caucasus Range extends from the Caucasian Natural Reserve in the vicinity of Sochi on the northeastern shore of the Black Sea, generally trending east-southeast and reaching nearly to Baku on the Caspian Sea, while the Lesser Caucasus runs parallel to the greater range, at a distance averaging about 100 km (62 mi) south.

Visible to the south of the mountains are three lakes arranged in a triangle: Lake Van, in Turkey (left), the reddish Lake Urmia, in Iran (right), and Lake Sevan, in Armenia. Each is the largest lake in its respective country.

Caspian Sea - August 29th, 2010

The Absheron peninsula in Azerbaijan juts out into the Caspian Sea on the right side of this image. It extends 37 miles (60 km) eastward into the sea, and reaches a maximum width of 19 miles (30 km).

Though technically the easternmost extension of the Caucasus Mountains, whose white peaks are visible running diagonally across the image towards the peninsula, its landscape is only mildly hilly. Most of the peninsula is a gently undulating plain that ends in a long spit of sand dunes known as Shah Dili, and now declared the Absheron National Park. In this part the peninsula is dissected by ravines and characterized by frequent salt lakes.

Two large lakes can be observed in west of the peninsula and south of the mountains: the Mingachevir Reservoir in Azerbaijan, greenish blue, and Lake Sevan in Armenia, dark blue and closer to the left edge. Also visible in the bottom left corner (completely visible in the full image) is Lake Urmia, in Iran, whose shores are ringed by white salt flats.

Armenia - November 24th, 2009

Lake Sevan is the largest lake in Armenia and one of the largest high-altitude lakes in the world. It is situated in the central part of the Republic of Armenia, inside the Gegharkunik Province, at the altitude of 1900m above sea level.

The total surface area of its basin is about 5000 km2, the lake itself is 940 km2, and the volume is 34.0 bln cubic meters. It is fed by 28 rivers and streams. Only 10% of the outgoing water is drained by the Hrazdan (Razdan) River, while the remaining 90% evaporates. Sevan is of volcanic origin and full of freshwater springs. Thus, in the middle of the lake, the water is pure and drinkable.

Before human intervention dramatically changed this ecosystem the lake was 95 metres deep, covered an area of 1,360 km² (5% of Armenia’s entire area), had a volume of 58 km³ and a perimeter of 260 km. The lake surface was at an altitude of 1,950 m above sea level.

Azerbaijan - May 17th, 2009

Two lakes are visible amidst mountain ranges in Azerbaijan (right) and Armenia (left).

The long lake near the center is the Mingacevir Reservoir, in Azerbaijan’s Kur-Araz Lowlands. It was created by the Mingacevir Dam, whose total capacity is 15.6 cubic kilometers of water.

The length of the reservoir is 70 km, width from 3 to 18 km, deepest point about 75 meters and total area 605 km².

Apart from the River Kur, the reservoir feeds two channels of the 172 km-long Upper Qarabag Channel and the 123 km-long Upper Sirvan Channel. These channels are used to irrigate 10,000 square kilometres of area in the steppes of Mil, Mugan and Sirvan.

Moving to the southwest, across the Bozdag Mountain chain into Armenia, one comes to Lake Sevan, in the province of Gegharkunik.

It is the largest lake in Armenia and one of the largest high-altitude lakes in the world, fed by 28 rivers and streams. Only 10% of the outgoing water is drained by the Hrazdan River, while the remaining 90% evaporates.

Before human intervention dramatically changed this ecosystem, the lake was 95 metres deep, covered an area of 1,360 km² (5% of Armenia’s entire area), had a volume of 58 km³ and a perimeter of 260 km. The lake surface was at an altitude of 1,950 m above sea level.
