. The hydrographic units of the most important rivers are
Lerabah sub-basin
Comoé sub-basin
Codoun sub-basin
Baoué sub-basin
Iringou sub-basin.
Water resources of the Mouhoun management area
The surface area of the Mouhoun Agency's jurisdiction is 91,036 km2. Its hydrographic network is made up of the :
Upper Mouhoun sub-basin
Lower Mouhoun sub-basin
Banifing sub-basin.
The most important dams are Samendéni (1.05 billion m3) for hydro-agricultural purposes and drinking water supply, Sourou (600 million m3) for hydro-agricultural purposes, Soum (83 million m3)
