The hydrological situation in the Niger basin during the month of March was characterized by decline of flow at the Inland Delta and the Middle Niger. While a low flow situation is observed at the Upper Niger and the Lower Niger.
The Sélingué water reservoir in Mali and Kainji water reservoir in Nigeria continue to release water to support the low flow situation in the basin.
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 (4) sub-catchments also represented with reference gauging stations as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger at Niamey (Niger) and Lower Niger at Lokoja (Nigeria)
