The hydrological situation in the Niger basin during the month of January was characterized by a continued decline in flows across the entire basin. In addition, a situation of low water has commenced at both the Upper Niger and Lower Niger sub-basins. The peak of the Guinean flood was recorded at the Niamey station during this month.
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 (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)
