Monthly Hydrological Bulletin. December 2019

During the month of November, the flow of River Niger was characterized by a low flow situation in the Upstream and the Lower Niger. In the Inland Delta at Diré, the flow began the decrease. As for the flow in the Middle Niger, the arrival of the Guinean flood continues.

The Selingue Dam in Mali and Kainji Dam in Nigeria have reached their maximum filling level and have started release so as to support low flow downstream.

The flow analysis was carried out by dividing the basin into four sub-catchments 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.
