The Black Volta or Mouhoun is a river in western Africa and the longest headwaters of the Volta .
course
The river has its source in the west of Burkina Faso, in the Forêt classée de la Source du Mouhoun nature reserve between Orodara and Banfora , and has a length of 1352 km. It initially flows in a north-easterly direction to the mouth of the Sourou . There it changes its course to the southeast and almost 100 km further south. Only about 500 km further does it flow again in large loops to the east, where it unites with the White Volta . The confluence of the two rivers is now mostly, depending on the water level, in the Volta reservoir .
The catchment area of the Black Volta is given as 142,000 to 149,000 km², of which a good 90,000 km² is in Burkina Faso, about 7,000 km² in the Ivory Coast, a good 9,000 km² in Mali and the rest in Ghana.
Part of the border between Ghana and Ivory Coast and Ghana and Burkina Faso is formed by the Black Volta.
