The month of June marks the starting of hydrological year in the Niger Basin. The commencement of the rainy season was timid, especially during the first decade of June, but the situation improved during the last decade of the month with a rise in flows over the entire basin as a result of pearly floods, to the rhythm of local rainfalls recorded.
The releases of the Sélingué Dam in Mali and Kainji Dam in Nigeria continues to support low flow at the upper Niger and Lower Niger.
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)
