The end of October month was characterized by a low flow in the Upper Niger Basin and the Lower Niger River. 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 filling up of Selingue dam in Mali and Kainji dam in Nigeria is ongoing.
The flow analysis situation was carried out on four reference gauging stations representing the four sub-catchments as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria)

Hydrological flow situation in the Niger basin during the month of April was characterized by a continued low flows in the Niger basin.

Regards to Dams, the reservoir water releases from Selingué Dam in Mali and Kainji and Jebba Dams in Nigeria continues to support low flows situation.

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)

During the month of November, the flow of River Niger was characterized by a low flow situation in all part of the sub-catchment areas, except the Inland Delta at Dire and downstream where the level of water is continuously rising because of the Black flood coming from up stream.

The Sélingué dam in Mali, Kainji, Jebba and Shiroro dams in Nigeria are in filling up situation and have reached an optimum reservoir capacity level.

In September the rainy season draws to its end on most of the Niger Basin. The concentration of the previous month runoffs in the main river has significantly increased the river water level and the rise of the flow is progressing.

The Sélingué dam in Mali, Lagdo dam in Cameroun, Kainji, Jebba and Shiroro dams in Nigeria are in filling up situation and have reached a significant reservoir 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 hydrological flow situation in the month of August 2015 was marked by the rise of the water level in all sub-basins of the Niger River basin. The local flood in Niamey observed this month has reached a maximum flow of 2123 m3/s equivalent to a water level of 580 cm on 5th August 2015. The flow situation needs more attention in the monitoring of the water level at hydrometric stations located upstream Niamey, namely stations on tributaries of the right bank of the River Niger which influence more the station of Niamey.
The Sélingué dam in Mali, Lagdo dam in Cameroun, Kainji, Jebba and Shiroro dams in Nigeria are in filling up situation.

The hydrological flow situation in the month of July 2015 was marked by the rise of the water level in all sub-basins of the Niger River basin. The local flood in Niamey observed this month has already reached a maximum flow of 1400 m3/s equivalent to a water level of 490 cm on 31stJuly 2015. This value is therefore the highest ever recorded during the month of July at this station of Niamey since gage height observations began in 1929. In this period, the flow situation needs more attention in the monitoring of the water level at hydrometric stations located upstream Niamey, namely stations on tributaries of the right bank of the River Niger which influence more the station of Niamey.

The Sélingué dam in Mali, Lagdo dam in Cameroun, Kainji, Jebba and Shiroro dams in Nigeria are in filling up situation.
