Hydrological flow situation in the Niger basin during the month of February was characterized by a continued decrease flow in the basin. Furthermore, dry flow situation was observed at the Upper and the Lower Niger.
Releases of water from Selingué Dam in Mali as well as Kainji Dam in Nigeria continue.
The data used for the various analyses below came from the National Hydrological Services and Dam Authorities of member countries.
The flow analysis situation was carried out by dividing the basin into four 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)

The hydrological flow situation of the Niger basin during the month of January 2020 was characterized by a low flow situation at the Upper Niger and the Lower Niger. While at the Inner Delta and the Middle Niger, the basin witnessed a mid-level flow situation due to the arrival of the Guinean flood or Black Flood, which started on these parts of the basin since November 2019.
Reservoir water releases from Selingué Dam in Mali as well as Kainji and Jebba Dams in Nigeria is on process to support the low flow situation at the Upper Niger and Low Niger.
The flow analysis situation was carried out by dividing the basin into four 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).

The end of October month was characterized by a low flow in the Upper Niger Basin. Meanwhile in the Inner Niger Delta and the Middle Niger the increase in flow continues due to the incoming black flood from upper Niger Basin. The Lower Niger River marks an alternation of the decrease floods and of the high “local floods”
The filling up of Selingue dam in Mali and Kainji dam in Nigeria have reached the normal filling level.
The flow analysis was carried out by dividing the basin into four sub-catchments 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).

In the month of September, the rainy season was drawing to its end on most part of Niger Basin. The concentration of previous months’ runoff water significantly contributed in increasing flow level in the Niger River’s main course where the flood wave were propagating.
The reservoirs of Sélingué dam in Mali and Kainji dam in Nigeria were being filled up and reached a significant filling level.
The hydrological analysis below covers four hydrometric stations representing four sub-catchments: Koulikoro (Mali) for Upper Niger, Dire (Mali) for Inner Delta, Niamey (Niger) for Middle Niger and Lokoja (Nigeria) for Lower Niger.

The hydrological situation in the Niger basin during the month of August 2019 was characterized by the continuous increase in flow in some catchment of Niger River Basin as a result of effective installation of rainy season.
The filling of Selingue Dam in Mali and Kainji Dam in Nigeria is ongoing.
The flow analysis situation was carried out on the four sub-catchments basin using the data recorded from the reference gauging stations which are: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria)

The hydrological flow situation of the Niger River Basin during the month of July 2019 was characterized by the continued rise of water in due to the installation of the rainy season.
During this period, it is noted that the Selingue dam on the Sankarani tributary in Mali and Kainji dam on the Niger River in Nigeria began their filling.
The flow analysis situation was carried out by dividing the basin into four 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)

The month of June 2019 marks the beginning of the 2019/2020 hydrological year in the Niger River basin. Overall, the month of June marked the onset of the rainy season throughout the basin area.
During this period, it is noted that the Selingue dam on the Sankarani tributary in Mali and Kainji dam on the Niger River in Nigeria still continue to release to support the low water.
The flow analysis situation was carried out by dividing the basin into four 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)
