The releases of the Sélingué dam in Mali and Kainji dam in Nigeria began continues respectively.
The data used for the various analyses below came from hydrological observation networks of the National Hydrological Services and Dam Authorities of nine (9) member countries.
The flow analysis situation was carried out by dividing the basin into four (4) sub-catchments also represented with reference gauging stations as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria)
