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)

During the month of December, the decrease in flows continued at the level of the Upper Niger, Inner Delta and Lower Niger sub-basins. On the other hand, in the sub-basin of the Middle Niger, there is a rise in water levels due to the influence of the Guinean flood.

Le mois de novembre a été caractérisé par la poursuite de la décrue dans le Bassin supérieur du fleuve Niger et le Niger Inférieur. Par contre, au niveau du Delta Intérieur et du Niger Moyen, la montée des eaux se poursuit à cause de l’influence progressive de la crue guinéenne.
Au niveau des barrages de Sélingué au Mali et de Kainji au Nigeria, les réservoirs sont toujours à leur niveau de remplissage maximum pendant ce mois de novembre.
Les données utilisées pour les différentes analyses ci-dessous proviennent des réseaux d’observations hydrométriques des Services Hydrologiques Nationaux et des Agences de barrages des neuf (9) pays membres de l’Autorité du Bassin du Niger (ABN).
L’analyse des écoulements dans le bassin du Niger est faite aux stations hydrométriques de référence, à savoir Koulikoro (Mali) pour le Niger Supérieur, Diré (Mali) pour le Delta Intérieur, Niamey (Niger) pour le Niger Moyen

The hydrological situation during the month of August 2022 was characterized by the continuation of the rise in the water level over the entire Niger River basin and the recording of some significant flash flood in certain sub-basins based on the situation of its rainfall conditions. At Niamey station, the water level reached the orange alert threshold on August 29, 2022.
As for the water level at Sélingué Dam in Mali, its filling began since 20th June 2022 due to the prevalence of the rainy season.

In the month of July, the rainfall is well confirmed in all compartments of the Niger basin causing sometimes very rapid rises in flows on the main course of the Niger River and its tributaries.
As for the water level at Sélingué Dam in Mali, its filling began since 20th June 2022 due to the prevalence of the rainy season.

The hydrological flow situation of the Niger basin during the month of January was marked by a low flow in the Upper Niger basin and in the Lower Niger basin. However, a decreasing flow situation is observed at the Inner Delta and the Middle Niger due to the low flows of the Guinean flood, which began in these parts of the basin since November 2021.
The Selingué dams in Mali and Kainji in Nigeria have begun to release water moderately to support the low flow situation downstream of the dams.
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)
