In January 2023, while a low flow situation is observed at the upper and Lower Niger basin, at the hydrometric station of Diré in the Inner Delta, an average flow situation is recorded due to the passage of the Guinean flood. However, at the Middle Niger, the Guinean flood, which started in this part of the basin, continued to reach its maximum on January 31st at the Niamey hydrometric station.
The Selingué dams in Mali and Kainji in Nigeria have begun gradual releases to support downstream flows.
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 of Niger Basin Authority. (NBA)
The flow analysis situation was carried out by dividing the basin into three (3) sub-catchments also represented with reference gauging stations as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali) and Middle Niger in Niamey (Niger)
