The hydrological flow situation in the Niger basin during the month of April was characterized by a continuation of low flow situation in the entire basin. However, there are some localized rainfalls recorded in some parts of the Upper and Lower Niger sub-basins.
The releases of Selingué reservoir in Mali and Kainji reservoir in Nigeria are gradually on-going to support the 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 (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)
