ABN/NBA - Système Observation Cycle Hydrologique du Bassin du Niger (Niger-HYCOS) - SIH/HIS

Monthly hydrological buletin. September 2015



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) as shown in figure 1.
