The Wachandarja (also written Wachan or Wakhan or called Wak ; Tajik Вахондарё Wachondarjo ; Russian Вахандарья ) is the left headwaters of the Pandsch in Central Asia .

River course

The river arises in the border area of ​​the Hindu Kush and Pamir mountains in the Badachschan province in the extreme northeast of Afghanistan near Baza'i Gonbad at an altitude of around 3885  m from the union of two mountain rivers:

  • The smaller one on the right has its source in ice fields at around 4900  m above sea level and initially flows southwest. When entering the broad high mountain valley of the Wachan corridor, which runs to the west-east, it forks in a large alluvial cone . The left branch flows over the moraine reservoir Shaqmaqtin into the northeast flowing Aksu . The right arm flows in the opposite direction as a wachan . However, both do not drain into different seas, but meet again at the confluence of the Bartang and Pandsch rivers.
  • The larger left source river is formed from the melt waters of several glaciers near the Wakhjir Pass , which are framed by mountain ranges up to almost 6000  m high and flows in an elongated course through a high mountain valley lined with extensive moraines of late Ice Age glaciers.

Together with this main spring river, the Wachan has a length of 220 kilometers. Then it joins southeast of the 6,726  m high Karl Marx peak near the border with Tajikistan near the village of Langar at an altitude of 2,799  m with the Pamir to the Pandsch .

A hydropower plant was built near Langar, which is already in Tajikistan in a narrow valley between the Hindu Kush and the Pamirs .
