In July, precipitation is installed on all compartments of the Niger Basin, with runoff coefficients higher than in June, at the beginning of the rainy season, due to the gradual saturation of soils. The flood in June is then replaced by a steady flow increase across the entire Niger Basin.
The reservoir filling of Sélingué Dam in Mali and Kainji Dam in Nigeria has started respectively during the second and the third decade.
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)
