The month of October was characterized by the beginning of a decline in flow situation at the Upper Niger and the Lower Niger Sub- Basins.  While the Inner Delta and the Middle Niger Sub – Basins witnessed increasing flow due to the incoming Guinean black flood.
The filling of the Selingué reservoir in Mali and the Kainji reservoir in Nigeria is in progress and has both reached normal reservoir capacity level.
