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.
